A key is given to 23 out of the total of 24 species now assigned to the genus. Five species at present placed in Lepidosaphes Shimer are transferred to the genus Andaspis MacGillivray and four of these are redescribed. Descriptions of two new species are included and a key is given to all the species known at present. Two closely related genera are described as new, one of which is monotypic and the other containing two species. INTRODUCTION ALL references prior to 1956 are to be found in Morrison & Renk, 1957 : 734. The lettering used in the figures is as follows : A. Adult female, general aspect. B. Pygidium. C. Dorsal margin of pygidium. I. THE GENUS LINDINGASPIS MACGILLIVRAY (ASPIDIOTINI) An excellent account was given by McKenzie (1950) of the genus Lindingaspis which then contained sixteen species. This number included the type species, L. samoana (Lindinger), which is still known only from a meagre description. Balachowsky (I953C, 1958) has since described three new species from Africa and illustrated two others which were not available to McKenzie. Yet another has been described from Kenya by De Lotto (1957). In the present paper, descriptions of two new species are given, one from Kenya and the other from Ceylon, and opportunity is taken to redescribe L. buxtoni (Laing), a species not discussed by McKenzie (1950) but tentatively assigned to the genus earlier by McKenzie (1939). The latter species, known only from Samoa, probably comes closest to the type species, also from Samoa. 4 D. J. WILLIAMS A total of twenty-four species is now known in Lindingaspis and a key to twenty- three of these is given on p. 10. The writer wishes to express his gratitude to Professor H. L. McKenzie, of the University of California, Davis, California, for kindly examining the three main species discussed and for giving his valued opinions. GEOGRAPHICAL DISTRIBUTION There has been no further evidence of an extension in distribution since McKenzie's discussion. All that can be stated is that the genus is not of new world origin. In the Palaearctic Region it is represented only in Japan by L. setiger (Maskell). Apart from L. rossi (Maskell), which is now almost a cosmopolitan species, eleven are known from the Ethiopian Region, five from the Oriental Region and two from Australasia. In the Pacific area only Samoa is known to possess its own species of which two seem to be most closely related to L. setiger from Japan. If it is assumed that the latter species represents an extension of the genus from the Oriental Region, there is possible evidence here, in common with many other groups of insects, that the Pacific species of Lindingaspis are an off-shoot of those from the Oriental Region. It seems obvious that many more species remain to be discovered. The Ethiopian Region will yield a good proportion of these but it is interesting that none has been discovered in the Malagasian area despite extensive collecting recently. Not a single species has been discovered in Indonesia or New Guinea but this is due probably to a lack of collecting as there are no ecological factors to exclude the group from these areas. The accompanying map (Text-fig. 4) shows the distribution based on holotype data. The known distribution of each species is given in the key. LINDINGASPIS MacGillivray Lindingaspis buxtoni (Laing) (Text-fig, i) Chrysomphalus buxtoni Laing, 1927 : 40, 41. Lindingaspis buxtoni (Laing) McKenzie, 1939 : 53. Described originally from SAMOA : Malololelei, on the bark of a shrub, July, 1924. Laing has described the scale as " deep brown to black, subcircular to elliptical, flatfish around the marginal area gradually rising to a very low nipple-like deep black excentric larval exuvium ; surface somewhat irregular and deposited in concentric layers. Size 4-5 mm. by 3 mm. in elliptical specimens, 3 mm. diameter in subcircular ones ". It is possible that the latter smaller scales are of the males. Adult female as mounted on the slide, rather large and attaining a length of 2-5 mm., slightly longer than wide, becoming sclerotized at maturity. Prosoma without lateral tubercles. Pygidium wide, with distinctive pattern of sclerotization as shown in the accompanying illustra- tion. Perivulvar pores in four groups, each anterior lateral group with 9-14 pores, posterior lateral groups each with 8-n pores, occasionally a single pore between the anterior groups. Vulva situated about one third length of pygidium from base. Anal opening smaller in diameter than a median lobe situated at centre of pygidium. Lobes well developed, there being three LINDINGASPIS AND ANDASPIS B FIG. i. Lindingaspis buxtoni (Laing) 6 D. J. WILLIAMS pairs present, median pair longest, each with single notch on outer margin ; second and third lobes about same size but smaller than median pair, each with two notches on outer margin. Plates small but distinct, apices fimbriate, distributed as follows : a pair between median lobes, a pair in each first interlobular space, three in second interlobular space and three beyond each third lobe. Beyond this point to seta of fourth segment, the margin is heavily sclerotized and serrate. Paraphyses prominent and well developed, some of the largest being clavate, the distinguishing features as follows : paraphyses arising from inner angles of all lobes by far the largest and wide ; the paraphyses arising from outer angle of second lobe small and slender ; paraphyses beyond third lobes wide and tending to be fused. Dorsal ducts of two sizes but the large-sized macroducts departing from the normal distribution in being numerous in the third interlobular space and extending well into the pygidium ; without a series of ducts extending forward from seta of fourth segment ; dorsal and ventral marginal macroducts reaching to point opposite second spiracles. This species departs from the general form of the genus in a few characters but the rather thick paraphyses between the lobes, the indeterminate and fused form of the paraphyses beyond the third lobes and the general sclerotic pattern of the pygidium ally this species to L. setiger (Maskell) known only from Japan. Lindingaspis fusca McKenzie Aspidiotus rossi Maskell ; Green, 18966 : 45 (Misidentification) . Aspidiotus rossi Maskell ; Green, 1937 : 831. (In part.) Lindingaspis fusca McKenzie, 1943 : 151, 152. Lindingaspis fusca McKenzie ; McKenzie, 1950 : 101. Specimens are at hand from Ceylon on Capparis moonii which were seen by Green and on which he based the first reference given above. These refer to L. fusca. Brain & Kelly (1917) thought that they had Green's species in South Africa and that this was different from A. rossi Maskell ; they accordingly named this species Chrysomphalus rossi var. greeni. It was indeed different from A. rossi but was also distinct from the Ceylon species. Lindingaspis kenyae sp. n. (Text-fig. 2) Scale of adult female purple-brown, about 2-0 mm. in diameter. Exuviae almost black, sub-central. Male scale more elongate but smaller, light purple-brown. Adult female attaining a length of 1-25 mm., slightly longer than wide. Thoracic tubercles prominent, situated at a point midway between the first and second spiracles. Pygidium rather narrow, rounded apically. Perivulvar pores in four groups, anterior lateral groups each with 5-8 pores, posterior lateral groups each with 3-6 pores. Anal opening slightly longer than a median lobe situated at centre of pygidium. Vulva situated nearer base of pygidium. Three pairs of well developed lobes present, all notched once on outer margin. Median lobes largest, each with broad basal sclerosis extending forward and as long as the lobe itself. Second and third lobes progressively smaller. Plates only slightly longer than lobes, with apices fimbriate ; there being one broad plate between median lobes ; a pair between each median and second lobe ; three between second and third lobes, the inner plate being quite small. There is a single membranous plate anterior to third lobe followed by two sclerotized plate-like structures. Anterior to this, pygidial margin heavily sclerotized and serrated to seta marking position of fourth segment. Paraphyses short as in accompanying diagram and with the following impor- tant characteristics : paraphyses arising from inner angle of median lobes slender and shorter LINDINGASPIS AND ANDASPIS FIG. 2, Lindingaspis kenyae sp. n. 8 D. J. WILLIAMS than basal scleroses ; those arising from outer angle of second lobes in two parts ; the middle paraphyses between second and third lobes short and slender, the spaces between the paraphyses of the second and third interlobular spaces sclerotized. Dorsal pygidial ducts of two sizes ; the large type between the interlobular spaces, there being two in the space between each median and second lobe ; the medium sized ducts extending along the margins and associated with the paraphyses, the row extending forward from near the seta which marks the position of the fifth segment reaching to a point midway between pygidial margin and lateral scar, a row also present from the seta marking position of fourth segment, these ducts extending to lateral scar but lying slightly inwards from the sclerotized area normally in this position ; two or three similar ducts also present anterior to lateral scar.

KENYA : Nairobi, on the leaves of Calanthe volkensii (Orchidaceae). In British Museum (Nat. Hist.). The material was submitted for identification by H. K. Airy Shaw, Royal Botanic Gardens, Kew. This species comes very close to L. fusca but differs in the following characters. The middle paraphysis between the second and third lobes is short and not longer than the paraphysis arising from the outer angle of the second lobe ; in L. fusca the middle paraphysis is noticeably longer. The medium sized ducts extending forward from seta marking position of fifth segment reach only halfway to lateral scar ; the pygidium is narrower and lacks the definite pattern of sclerotization found in L. fusca. Lindingaspis mackenziei sp. n. (Text-fig. 3) Aspidiotus rossi Maskell ; Green 1937 : 33 1 - (I* 1 part.) Scale of adult female dark chocolate-brown with sub-central exuviae even darker. About 2 -5 mm. in diameter. Male scale similar to that of female but smaller and more elongate. Adult female about 1-5 mm. long, a little longer than wide. Prosomatic region membranous with thoracic tubercles on level with posterior spiracles. Pygidium narrow with sides noticeably concave, apex rounded. Perivulvar pores in four groups, each anterior lateral group with 11-16 pores and posterior lateral groups each with 5-11 pores, there being noticeable sclerotized areas on the inner sides of the anterior groups. Perivulvar pores and vulva situated near base of pygidium. Anal opening slightly larger than a median lobe, situated near centre of pygidium. Three pairs of lobes present, all of similar size and shape ; each with a distinct notch on outer margin but third lobe often with two notches ; a minute notch also present at base on inner margins. Plates well developed and slightly longer than lobes, apices fimbriate ; a pair between median lobes, a pair between median and second lobes, three between second and third lobes and a single membranous plate lateral to third lobes followed by a pair of sclerotized plate-like processes ; margin forward from these plates to a point near seta of fourth segment sclerotized and serrated. Paraphyses well developed, the important characteristics being the paraphyses arising from inner and outer angles of second lobes being of equal length and middle paraphysis in the third interlobular space noticeably longer than the two lateral paraphyses in this space ; outer angle paraphysis of median lobe much longer than inner angle paraphysis of median lobe. Dorsal ducts of the two usual sizes, there being two large macroducts in the second interlobular space ; a row of medium sized ducts extending forward from seta on fourth segment and row extending forward from near seta of fifth segment reaching a point about LINDINGASPIS AND ANDASPIS FIG. 3.

This species comes closest to L. similis McKenzie described from Samoa but differs in possessing two large macroducts in the second interlobular space instead of three or four, the plates are much less differentiated, the outer angle paraphysis is much longer than the inner angle paraphysis on the median lobes whereas in L. similis they are of similar length and the vulva is situated near base of pygidium instead of near centre as in L. similis. It differs from L. tingi mainly in the similar size of the lateral angle paraphysis of second lobes whereas in L. tingi the outer angle paraphysis is about one half the length of the mesal angle paraphysis. The species is named after Professor Howard L. McKenzie who has given the author valuable assistance on various matters in connection with the present paper and on many other occasions.

THE GENUS ANDASPIS MACGILLIVRAY WITH DESCRIPTIONS OF TWO NEW ALLIED GENERA (DIASPIDINI) In a revision of the genus Andaspis, Rao & Ferris (1952) assigned to it a total of ten species. Since then further species have been added which, together with others transferred from Lepidosaphes in the present paper, and two new species, give a total of twenty-two species now in the genus. It is not the intention here to enlarge on the definition of the genus given by Rao & Ferris. As these authors have pointed out, the type species of the genera Andaspis and Lepidosaphes are quite different but the difficulty is to determine a I 4 D. J. WILLIAMS point at which these genera can best be separated. The most important character clearly separating the two genera is the shape of median lobes. In a key to genera, Hall (1946) has given an excellent definition of the median lobes in Andaspis as being " close together, with inner margins straight, diverging slightly apically before curving round to a long oblique outer margin ". This outer margin has numerous notches and the normal lateral margin is either short or non-existent. In Lepidosaphes and its nearest relatives the median lobes have one or two notches on the outer margins but the sides always show some signs of being parallel. There are possibly intermediate forms at present placed in the genus Lepidosaphes but until this genus is revised the following species are best retained in Andaspis. The type species is almost cosmopolitan but its most important and interesting distribution is in the Oriental Region. Another species, described from U.S.A., is known from Hawaii but is recorded by Zimmerman (1948) as being intercepted from the Philippine Islands and Singapore at Hawaii. It is expected that this species will be found eventually in the Oriental Region. Of the remaining species three are known from Japan and these may be regarded as an extension of the twelve species known from the Oriental Region. Two have been described from the Austra- lasian Region and three from the Ethiopian Region which include one from Mauritius as a representative of the Malagasian area. As is common with many groups within the Coccoidea none has yet been described from Indonesia, the Philippine Islands or New Guinea, although doubtless in due course some interesting forms will be discovered in these areas. It seems possible, however, that the genus has had its origin in the Oriental Region and the numbers now known from there represent a small fraction of those still to be discovered. Included in the present revision are descriptions of two new genera which come close to Andaspis. One of these is represented by a single species from West Pakistan. The other genus contains two species, one from Northern Australia and the other from Java. Both of these genera come within the known range of distribution of Andaspis. ANDASPIS MacGillivray Andaspis dasi sp. n. (Text-fig. 5) Female scale greyish, almost transparent, rather wide posteriorly, about 1-5 mm. long, exuviae yellow brown. Male scale not seen. Adult female fusiform about 1-2 mm. long, membranous except for pygidium, lateral margins of mesothorax, metathorax and first four abdominal segments quite strongly lobed. Lateral sclerotized spurs present on first to third abdominal segments. Anterior spiracles each with a group of 6-10 pores. First six abdominal segments each with blunt spur or boss on dorsum near margin and a pair set close together on each side of prothorax. Pygidium rather pointed, with median lobes prominent, triangular, each with long blunt paraphysis at base. Second lobes much smaller but bilobed condition easily discernible, smooth. Gland spines in pairs on pygidium, very slender, those between median lobes small. Marginal macroducts numbering 6 pairs. Dorsal ducts small and slender, a large submedian LINDINGASPIS AND ANDASPIS FIG. 5. Andaspis dasi sp. n. 16 D. J. WILLIAMS group present on sixth segment and anterior to this on third to sixth segments the ducts form almost continuous rows whilst beyond these to mesothorax they are present around the sub- margins. Ventral surface with perivulvar pores in five groups, median group with 4-10 pores, each anterior lateral group with 10-15 pores and each posterior lateral group with 8-14 pores. Microducts in distinct groups on pygidium ; present also around the margins and in the median area of mesothorax. Small gland spines sparse, on margins as far forward as first abdominal segment ; absent on metathorax. Holotype. $. INDIA: West Bengal, Dooars, on Camellia sinensis(Csnne\lia.ce3ie), 1958 (G. M.

Scale of adult female narrow, elongate, about 1-5 mm. long ; dark reddish brown to almost black ; exuviae pale reddish brown. Male scale about half length of female scale, light reddish brown. A small elongate species measuring approximately i-o mm. long, pygidium always sclerotized, remainder of body either membranous or somewhat sclerotized. Anterior spiracles each with usually two pores. With small sclerotized spurs on the second, third and fourth segments. A small rounded submarginal spur or boss present dorsally on the first, second and fourth segments. Pygidium with median lobes prominent, triangular and of the type common to the genus ; apical margin straight and dentate ; ventral surface of lobe with mid-basal seta each with the socket forming a small sclerosis on inner side ; setae at basal angles normal. Second lobes well developed, bilobed, the inner lobules with two or three notches. Gland spines in pairs ; those between median lobes and between median and second lobes short and no longer than the lobes. Anterior gland spines much longer. Marginal macroducts numbering six pairs. Dorsal ducts small, a submedian group on the sixth segment and submarginal and submedian groups distinct or almost merging on the three preceding segments. Ventral surface with three groups of perivulvar pores ; median group with 2-4 pores, anterior laterals each with 5 or 6 pores, posterior laterals each with 2-4 pores. Microducts on the pygidium in small groups, sparse. Small gland spines on abdomen only, more numerous on the first abdominal segment, absent on the metathorax. Although this species is extremely close to A . punicae (Laing) there are a few small differences. In A . punicae there are small scleroses at the basal angles of the median lobes formed from the sockets of small setae whereas in A. hibisci these sockets are normal. On the other hand a ventral mid-basal seta on the median lobe of A. punicae is normal whereas in A . hibisci the socket forms a noticeable sclerosis. The LINDINGASPIS AND ANDASPIS FIG. 6. Andaspis hibisci (Grandpre & Charmoy) i8 D. J. WILLIAMS lateral sclerotized spurs of A . hibisci are, apparently, absent in A . punicae. Specimens have been examined from MAURITIUS on Hibiscus sp. (Malvaceae) sent originally by D. D'Emmerez de Charmoy and on H. rosa-sinensis collected by R. Mamet 26.^.1934. Andaspis kazimiae sp. n. (Text-fig. 7) Scale of adult female known from alcohol material only, pale reddish brown, of the form typical of the genus, about 1-5 mm. long. Male scale of similar colour but smaller. Adult female elongate oval attaining a length of 0-8 mm., membranous except for pygidium. Without marginal sclerotized spurs. Antennae with two long setae. Anterior spiracles with usually a single pore. Pygidium with anal ring at base. Median lobes large and prominent, triangular but with apices somewhat rounded ; the dorsal surface with a transverse sclerotized bar almost connect- ing the basal angles ; the ventral surface with two well developed paraphyses arising from basal angles. Second lobes well developed, represented by a single lobule only, each longer than wide and notched on each margin ; these lobes with a characteristic curved appearance which is emphasized by the curved paraphyses arising from the lateral angles. Gland spines in pairs between the median lobes, between the median and second lobes and lateral to the second lobes. Beyond these on the fourth and fifth segments they are single. Marginal macroducts numbering four pairs. Dorsal ducts sparse, there being a few submarginal groups as far as metathorax and submedian groups on the third to sixth segments, those on segments five and six being usually in pairs. Ventral surface with perivulvar pores in three groups ; median group with 3 or 4 pores, anterior lateral groups each with 6-8 pores and posterior lateral groups each with 4 or 5 pores. Small gland spines present on metathorax and first abdominal segment. Holotype. $. WEST PAKISTAN : Behrain, on Quercus sp. (Fagaceae), 20. x. 1961 (S. K. Kazimi), in British Museum (Nat. Hist.).

This species possesses only four pairs of pygidial macroducts, a character shared with A . laingi Rao and A . retrusa (Green) . It differs from these species in the well developed second lobes and in the paucity of dorsal ducts. Andaspis mackieana (McKenzie) (comb, n.)

As the median lobes are of the shape common to those in Andaspis the species is here transferred from Lepidosaphes, a move with which Professor H. L. McKenzie is in full accord. Although only known from U.S.A. and Hawaii, according to Zimmerman (1948) it has also been intercepted at Hawaii on material from the Philippine Islands and Singapore. LINDINGASPIS AND ANDASPIS B FIG. 7. Andaspis kazimiae sp. n. 20 D. J. WILLIAMS Andaspis meliae (Green) (comb, n.) (Text-fig. 8) Lepidosaphes meliae Green, 19190 : 445, 446. Mytilaspis (Lepidosaphes) meliae Green ; Ramakrishna Ayyar, igiga, : 24. Scale of adult female dull dark brown, moderately convex, attaining a length of 2-5 mm., exuviae reddish brown, often with whitish secretion. Scale of male smaller, about 1-2 mm. long, dark brown to almost black. Adult female broadly oval, about 1-2 mm. long ; membranous except for pygidium. Marginal sclerotized spurs absent. Antennae with four setae of various sizes. Anterior spiracles each with a group of 3-5 pores. Pygidium with prominent median lobes of the form common to the genus except that apices tend to be more rounded. Second lobes bilobed, the inner lobules barely perceptible. Gland spines in pairs on pygidium. Marginal macroducts numbering six pairs. Dorsal ducts minute, there being a submedian group on the sixth segment and a smaller group on seventh segment. Anteriorly on the abdomen there are submarginal and submedian groups. Ventral surface with perivulvar pores in five groups, median group with 5-12 pores, anterior laterals each with 17-21 pores and posterior laterals each with 10-15 pores. A few submarginal microducts on pygidium. Gland spines present on abdomen only, pointed except on first abdominal segment where they are replaced by small sclerotized gland tubercles. Described originally from INDIA : Coimbatore, on the " Nim " tree, Melia azederach (Meliaceae), S.iii.igiS (T. V. Ramakrishna Ayyar}. In their revision of the genus Andaspis, Rao & Ferris (1952) considered this species for inclusion but excluded it without any definite reason. It comes very close to A. mori Ferris in the general distribution of ducts and in the shape of the median lobes but differs in possessing much larger second lobes and lacking the sclerotized spurs on the margins of the abdomen. Andaspis mori Ferris Andaspis mori Ferris ; Rao & Ferris, 1952 : 21. Andaspis mori Ferris ; Ferris, 1953 : 59. Specimens are at hand from FORMOSA : Kagi, on Sapindus sp. (Sapindaceae) , i.xi.i927 (R. Takahashi), which differ slightly from the description given by Ferris. They possess only two gland spines lateral to each second lobe instead of three and more numerous submedian ducts on the seventh segment. In other respects the specimens are identical. Professor H. L. McKenzie of the University of California, Davis, California, has very kindly compared these specimens with the holotype and given some useful information for which the writer is most indebted to him. So far as is known Dr. R. Takahashi has not mentioned this record in any of his publications. Andaspis retrusa (Green) (comb, n.) (Text-fig. 9) Lepidosaphes retrusus Green, igigc : 446. Mytilaspis retrusus (Green) Ramakrishna Ayyar, igiga : 24. Scale of adult female dull to reddish brown, moderately convex, up to 1-5 mm. long, exuviae tending to be yellow brown. Male scale lighter and paler in colour, length about i-o mm. LINDINGASPIS AND ANDASPIS 21 FIG. 8. Andaspis meliae (Green) 22 D. J. WILLIAMS B FIG. 9. Andaspis retrusa (Green) LINDINGASPIS AND ANDASPIS 23 A broadly oval species measuring approximately 0-8 mm. long, membranous except for pygidium but in some specimens body tending to become sclerotized. Without lateral spurs on abdomen. Anterior spiracles with 1-3 pores. Pygidium broadly rounded. Median lobes prominent and wide, separated by a space slightly less than half the width of one lobe, each lobe with small blunt paraphyses arising from inner basal angle. In some specimens the lobes have parallel sides but in most specimens they are the usual triangular shape. Second lobes present, much smaller than median lobes, bilobed, the inner lobule usually with a single notch. Gland spines slender, in pairs on the pygidial segments, those between median lobes about the same length as the lobes. Marginal macroducts numbering four pairs. Dorsal ducts very small, numerous, the derm surrounding the orifices of posterior ducts often sclerotized. On the sixth and anterior abdominal segments the sub- marginal and submedian ducts merge into continuous rows ; present also around the submargins on the thorax. Ventral surface with perivulvar pores in five groups, the median group with 6-12 pores, anterior laterals each with 8-18 pores and posterior laterals each with 11-18 pores. Microducts in distinct groups on pygidium and in submarginal groups on the prepygidial abdominal segments and thorax. Small gland spines sparse, there being at most only one or two on the abdominal margins and metathorax but sometimes absent entirely on one or more segments. Green described this species from INDIA : Nilgiris, Dodabetta, on the mid-rib and principal veins on the underside of leaves of Litsea whiteana (Lauraceae). In possessing only four pairs of pygidial macroducts it comes close to A. laingi Rao but differs in possessing more numerous dorsal ducts and in lacking the marginal sclerotized spurs. Only three pairs of marginal macroducts were mentioned in the original description but there are clearly four pairs in all of the material studied. Andaspis vandae (Rutherford) (comb, n.) (Text-fig. 10) Lepidosaphes vandae Rutherford, 1915 : 116. Lepidosaphes vandae Rutherford ; Green, 1937 : 328. Scale of adult female very dark brown to nearly black, shiny, about 2-75 mm. long, exuviae dull brown. Male scale slightly paler than female scale and smaller. Adult female elongate-oval, about 1-5 mm. long, membranous except for pygidium and head margins ; pygidium rounded. Anterior margin of head with a number of small conical processes resembling minute gland spines but structure difficult to determine. Lateral sclerotized spurs on the second, third and fourth abdominal segments. Anterior spiracles each with a group of 9-14 pores. Pygidium with median lobes prominent, triangular and of the form typical of the genus. Second lobes smaller than the median pair. Third and fourth lobes represented by large sclerotized projections. Marginal macroducts numbering six pairs. Dorsal ducts minute. A small group present on seventh segment and a larger submedian group on sixth segment. On the prepygidial abdominal segments the submarginal and submedian ducts merge into almost continuous rows. Ventral surface with perivulvar pores in five groups. Median group with 5-9 pores, each anterior lateral group with 12-15 pores and each posterior lateral group with 9-15 pores. Microducts on pygidium in groups, each with orifice opening on to a clear area of the derm. Small gland spines present on the abdominal segments, not numerous ; absent on the metathorax.

Second and third lobes represented by, at most, small sclerotized points. Marginal macroducts present. Anal opening situated towards apex of pygidium. This genus has close affinities with Andaspis but differs mainly in the shape of the median lobes which have only one or two notches on the lateral margins and in the position of the anal opening which is situated towards the apex rather than at the base of the pygidium. Caia quernea sp. n. (Text-fig, n) Scales not seen. Adult female elongate oval, fusiform, about i-o mm. long, membranous except for pygidium. Lateral sclerotized spurs absent.

Second and third lobes absent or at most represented by small sclerotized points. Seta on the margin of the seventh segment with the base heavily sclerotized and with the inner part of the socket large and extending into the pygidium. Gland spines in pairs on pygidium, those between median lobes very slender and about as long as lobes. Marginal macroducts numbering four pairs. Other dorsal ducts much smaller and becoming smaller anteriorly ; submedian group on segment six absent ; distinct submedian groups present on segments two, three and four ; submarginal groups present as far forward as the mesothorax.

Type species : Mytilaspis recurvata Froggatt. Female scale elongate, exuviae terminal. Male scale smaller, smooth. A genus of the tribe Diaspidini and of the Lepidosaphes group with two-barred ducts, these minute and distributed in no definite arrangement on the pygidium ; marginal macroducts absent. Gland spines present, a pair of which lie between the median lobes. Anal opening at the base of pygidium. Median lobes prominent, triangular, the apical margin, at least, with numerous notches. Anterior spiracles with pores. This genus comes close to the genus Andaspis, differing in lacking marginal macroducts which are replaced by minute ducts similar to the dorsal ducts. The shape of the median lobes appears to be variable but the lateral margin is diagonal to the longitudinal axis of the body. Metandaspis recurvata (Froggatt) (comb, n.) (Text-fig. 12) Mytilaspis recurvata Froggatt 1914 : 683. Scale of adult female elongate, white, often peculiarly bent, sometimes at right angles or even U-shaped.

Lateral sclerotized spurs absent. Anterior spiracles each with usually a single pore. Pygidium with median lobes prominent, the apical margin quite long and serrated, and with a slender paraphysis arising from near each basal angle. Second lobes well developed, bilobed, the inner lobules variously notched. Sclerotized projections present in the places of the third and fourth lobes. Gland spines present in pairs on pygidium, the pair between median lobes shorter than the lobes. Dorsal minute ducts distributed rather evenly on pygidium and in more or less transverse rows on fourth and fifth segments and around the submargins to meta- thorax ; ducts on pygidium each with sclerotized area surrounding orifice. Ventral surface with microducts sparse on pygidium but more numerous around submargins. Perivulvar pores absent. Small gland spines present as far forward as metathorax.

Male scale similar but smaller. Adult female elongate about 0-6 mm. long, sides subparallel. Body membranous except for pygidium but older individuals often sclerotized on head margin and in a characteristic pattern on the prepygidial abdominal segments. Without lateral sclerotized spurs but dorsal surface with submarginal tubercles which are rounded, blunt and sclerotized on first to sixth segments. Anterior spiracles with 2 or 3 pores. Pygidium with very prominent median lobes departing from the usual shape of those of the Andaspis series in having inner and outer margins roughly equal in length but entire margins serrated ; ventral surface with well developed basal scleroses extending into pygidium and with paraphyses, the inner of which extends forwards near the midline. Second lobes smaller than median, with outer margins much longer than inner, serrated ; ventral side showing paraphyses. Gland spines very small, there being two between median lobes and arranged in pairs on remainder of pygidium. Dorsal ducts minute, numerous, in no definite arrangement on pygidium ; in transverse rows as far forward as metathorax. Ventral surface with perivulvar pores in three groups arranged in a broad arc ; median group usually with two pores, laterals each with usually four pores. Microducts quite numerous in transverse rows on abdominal and thoracic segments. Holotype. . JAVA : without known locality, on Pterospermum javanicum (Sterculiaceae), (A. Zimmerman), in British Museum (Nat. Hist.). Paratypes. 8 $. JAVA : same data as holotype, in British Museum (Nat. Hist.). There is some doubt as to whether this species belongs to the same genus as the previous species. The very prominent median lobes are the chief distinguishing characters together with the peculiar paraphyses on the ventral surface and the large basal scleroses. Rather than erect a new genus it may remain here until further related species are discovered. REFERENCES BALACHOWSKY, A. S. 1958. Les Cochenilles du Continent Africain Noir. Vol. 2.

KIMMINS SYNOPSIS A study of the collections made by the two British Museum (Natural History) Expeditions to Nepal, 1954 an d 1961-62, has resulted in a list of twenty-eight species, of which one genus and fourteen species are here described as new. BOTH expeditions included an entomologist, Mr. J. Quinlan in 1954 and Mr. R. L. Coe in 1961-62, but in neither case were Trichoptera the sole object of their attentions. The present list can therefore be regarded only as a beginning, and specialised collecting, over a wider area, will undoubtedly result in a very much greater list. As far as I know, no previous list of Nepalese Trichoptera has been published. In addition to those included in the present list, two other species have already been described in manuscript by Dr. F. Schmid. The types of new species described in this paper are in the British Museum (Natural History). To save space, collector's initials only are given in the list, (RLC) = R. L. Coe and (JQ) = J. Quinlan. Family RHYAGOPHILIDAE Rhyacophila sp. n. A This species is being described by Schmid. Taplejung Distr., Sangu, c. 6,200 ft., xi. 1961-1.1962, i $ (RLC).

This species is closely related to S. incurvatus Kimmins (Burma), differing in the longer cercus, which is more strongly convex on its inner surface, and in the details of the clasper, especially in the presence of a row of comb-like teeth on the inner surface. A single female Synagapetus from Sangu may belong to this species, but as it comes from a different locality, it is left undetermined. Nepaloptila coei gen. n., sp. n. (Text-figs. 5-8) o*. The holotype was not in good condition and has been mounted as a microscope preparation. The general colour was dark grey, with greyish pubescence on the wings. Spurs 0.4.4. Pronotum with the dorsal surface densely covered with erect, blackish, scale-like hairs. Two rounded warts present on mesoprescutum, two on mesoscutum (one on each side of scutellum), the latter without warts. Wings rather narrow, venation lightly sclerotized, cross-veins somewhat obscure. In fore wing, all five apical forks present, forks R 2 and R t very long and narrow, R 2 with a short footstalk, R t sessile. These two forks extend basally to the middle of the wing. The discoidal cell extends from the middle of the wing to within one fourth from the base. The media forks at about the middle of the wing, forks M : and M 3 stalked. Veins Cu 1 and Cu z run separately into the wing margin, fork Cu l& sessile. Vein Cu 2 with a row of stout setae about midway on the under surface.

Process of the sixth sternite slender, slightly clavate apically in side view. Ninth segment with the centre of its dorsal apical margin produced in a strong, triangular tooth, curving slightly downwards. Tenth segment fused to ninth, appearing as a pair of short, downwardly directed processes, one arising from each upper lateral margin of the ninth segment. Aedeagus long, stout basally, its apex tapering to an acute point and with its dorsal surface before the apex bearing some inflated membrane, within which are two curved, sclerotized rods and some spines. Claspers fused to ninth segment, broad at base in side view, extending in a digitate process, whose apex is slightly dilated in ventral view, the inner apical angle toothed. Between the claspers, the margin of the ninth sternite is produced in a broad triangle, whose apex is bilobed slightly, each lobe terminating in a seta. $ Unknown. Length of fore wing, <$, 2-5 mm. Holotype ^ (mounted as microscope preparation), Arun Valley, below Tumlingtar, R. Sabhaya, west shore, c. 1,800 ft., on dead leaves lying in sun on sandy shore, 22.xii.i96i (RLC), BMNH. The holotype has very much the appearance of a small Agapetus, but it has been placed in the Protoptilinae on the absence of mesoscutellar warts, the presence of rounded warts on the mesoscutum and the presence of stout setae on Cu 2 in the fore wing. The venation recalls that of the Agapetinae, but in this subfamily stout 38 D. E. KIMMINS setae on or near Cu 2 in the fore wing are unknown and there are always warts on the mesoscutellum. Apical fork Cu la is usually lacking in the Protoptilinae, where Cu and Cu 2 often fuse apically in the fore wing, although they are separate in Matrioptila. The general plan of the venation is otherwise like that of Matrioptila and the male genitalia also show some resemblance. In its retention of fork Cu^ in the fore wing, Nepaloptila would appear to be more primitive than Matrioptila, and this makes its discovery in Asia a matter of some interest, since all previous records of Protoptilinae are from the New World. The presence of warts on the mesoscutellum has been listed by Ross (1956) as one of the characters of a primitive caddisfly ; these warts occur in the Agapetinae and are lacking in the Protoptilinae.

ON THE TRICHOPTERA OF NEPAL 51 In the absence of males, these two specimens are left with a generic determination only. Several species have been described from China, based upon males only, and since there is a sexual dimorphism in the venation, it is preferable to wait until males are available.

Uenoa spp. " of this species, which is a male, has been examined by courtesy of the Humboldt Universitat, Berlin. The type male mentioned by Grose-Smith & Kirby is apparently missing. The specimen of rezia above shows an evenly curved distal margin to the fore wing, whereas in 4 specimens of benitensis Holland, before me, 2^2$, the distal margin is distinctly angled at vein 3. The markings, however, both above and below, are identical. On the shape of the distal margin of fore wing of benitensis and due to the paucity of material of rezia it is felt safer to use the two names with the proviso that they are possibly conspecific. It is significant that at the end of the original description Grose-Smith & Kirby state : " We believe that Dr. Holland considers the specimen figured to be his Epitola benitensis (Psyche, vol. V, p. 425), but the anterior wings of our species do not exhibit the peculiar 'falcate' form which he describes ".

INTRODUCTION THE dipterous fauna of Nepal is poorly known and this paper attempts to bring up to date both published and new records of Stratiomyidae, Therevidae and Dolichopodidae from this country. The work was stimulated by the collections of two British Museum expeditions to Nepal. On the first expedition, in 1954, the Diptera were collected by Mr. J. Quinlan. The second expedition, during the winter of 1961-62, provided the bulk of material studied and this collection was made by Mr. R. L. Coe. One new species, Hercostomus kaulbacki sp. n. from Tibet is described here because of the proximity of the locality and the unusual characteristics displayed by the fly. A full bibliography of the recorded species is not given and only references to taxonomic changes and new locality records are stated. Unless otherwise stated all type material is in the British Museum (Natural History) . The author would like to thank Mr. C. E. Dyte, of the Pest Infestation Labora- tories, Slough, for his valuable advice and criticism ; Mr. W. N. Ellis, of the Zoologisch Museum, Amsterdam, for the helpful loan of type material ; and Dr. Sadao Takagi, of the Entomological Institute, Hokkaido University, Sapporo, for his gift of type material to the British Museum. 84 D.

Trustees of the British Museum (Natural History) 1964 TRUSTEES OF THE BRITISH MUSEUM (NATURAL HISTORY) Issued 2ist July, 1964 Price Ten Shillings NEW SPECIES OF UGYOPS ? (FULGOROIDEA : DELPHACIDAE) FROM SOUTH AMERICA AND SOUTH-EAST ASIA By R. G. FENNAH SYNOPSIS The external characters of value in classifying members of Ugyops (Fulgoroidea : Delphacidae) are discussed. Seventeen new species and two new subspecies are described from the following localities : Panama, Brazil, Narcondam Island, Krakatau Island, Thailand, Borneo, New Guinea, New Hebrides, New Caledonia and Niue. SOME series of Ugyops from Brazil and south-east Asia standing in the unnamed accessions of the British Museum (Nat. Hist.) have proved to represent new species, and these are described below. Our knowledge of this genus is still fragmentary. Its members are impressively widespread among oceanic islands of the Pacific, are found in the Mascarene Islands, and range through tropical South America into the Greater Antilles. In the conti- nental areas of the Old World, however, the position, as far as yet known, is very different ; the genus is not represented in Africa and in continental Asia has been found only on the south-eastern seaboard, in " Cochin-China ". It is known that species of the genus occur in northern Australia, New Guinea, the Moluccas, Borneo and Sumatra and in some of the smaller islands of Indonesia, but the only evidence of its presence on the continent immediately north of Java and Sumatra is provided by specimens from Thailand in the present collection, and of its presence in the eastern part of the Indian Ocean by a specimen from Narcondam Island. In the delphacine Delphacidae it is customary to seek differences in the form of the male genitalia as the chief criterion for distinguishing species. In some of the Asiracinae, however, including the genus Ugyops, it is the external bodily features that exhibit the greatest amount of diversity. The range of such variation between members of a series, even between the sexes, is relatively very small, whereas between members of different species (as determined by genitalic differences and sympatric distribution) there is an evident gap between the ranges found in each. It may accordingly be assumed that the form of such bodily features is of specific value. The numerous re-combinations of " characters " found in members of Ugyops have so far not been found to form a pattern that would suggest a natural sub- generic classification. None the less, there are two main types of bodily form that afford a crude but useful basis for separating species-groups. The first of these is exemplified by the dimensions of U. percheronii Guer. and U. kinbergi Stal : members of these species are large, macropterous, with a narrow, usually parallel-sided, vertex, usually an acutely angulate profile, a frons about three times as long as broad, slender antennal segments and a pygofer elongate ventrally. The second is 120 R. G. FENNAH exemplified by U. annulipes Stal (placed by him in a separate genus, Livatis) : its members are moderately short, or even quite small, coelopterous (with the tegmina just covering the abdomen), and with a relatively broad vertex, often wider apically than at the base, a convex profile, a frons about two and a half times as long as broad, antennal segments not very slender, and a relatively short pygofer. In this second group wings may be present or absent ; the tegmina may be abbreviated to less than the length of the abdomen, and, rarely, may be brachypterous. There is generally little difficulty in deciding to which of these groups a specimen of an unknown species belongs, but thereafter the task of establishing its relationship with a known species on the basis of a verbal description may be far from easy. In the writer's experience, the degree of curvature of the margins of the head, the form of the frontal carinae and the relative proportions of the head and of the antennal segments are reasonably constant within a species, as is the colour pattern of the body and tegmina (as opposed to the rather variable colour intensity) ; these characters, in combination, vary sufficiently between species to provide a reliable means for specific determination. Variation in colour intensity between individuals of a species is common, but never extreme. Members of a series may, for instance, vary from very pale with small irregular dark areas to pale with each dark area twice as large (but occupying a truly corresponding position) : the range does not extend further to include the development of wholly dark coloration. As far as the writer knows, mere variation in intensity of pigmentation does not totally obscure the differences in colour pattern between one species and another. The measurements of the antennal segments given below represent, in each in- stance, the distance from the base to the apex. The basal segment is often of unequal width throughout, and the width is arbitrarily measured at the middle. The vertex may be horizontal or declivous, and when declivous appears shorter in direct dorsal view than in a more or less anterodorsal view. The measurement of its length is taken in each case from whichever viewpoint the maximum length of vertex can be seen : the length is taken along the middle line, from the apex of the projection in the middle of the apical margin to the middle of the basal margin, which is often very slightly angulately produced caudad. The width at the base includes the thickness of the lateral margins at this level. The writer's warmest thanks are tendered to the authorities of the British Museum (Natural History) and to Mr. J. P. Doncaster, Keeper of the Department of Ento- mology, for the privilege of studying this most interesting assemblage of specimens.

NEW SPECIES OF UGYOPS 121 Ugyops samoaensis ferus subsp. n. Form and coloration similar to that of typical subspecies.

Muir recognized that this population was distinct from the typical form from Tutuila in Samoa, and described the difference in the conformation of the pygofer. This difference is now considered sufficiently important to warrant the application of a formal subspecific name to the Niue population. The latter is rather similar to that of U. necopinus Fenn. (from Fiji), but necopinus differs from samoaensis in having a vertex relatively shorter in relation to its basal width (scarcely more than 1-4 : i, as compared with more than 1-5 : i in samoaensis), and, in the male, an anal segment with the apical angles asymmetrically produced ventrocaudad (the margin in samoaensis being symmetrical).

These examples have hitherto stood in the typical series of Epibidis godmani Fowler. From this species U. palliatus differs in its relatively longer second antennal segment (the ratio of second to first in godmani is 1-6 : i), colour pattern and, to a surprisingly large extent, in the male genitalia. The structures exhibited by U. godmani are shown for comparison. Superficially the two species can be separ- ated by the continuous broad dark band across the middle of the tegmen in palliatus. The degree of extension of this band towards the base of the tegmen is variable : the maximum development is shown in the figure. Epibidis brunnea Fowler is of larger bodily size and of entirely different colour pattern as well as of a darker colour. A male of the present series has possibly been used to provide the descrip- tion of the male genitalia given for brunnea by Fowler. Ugyops godmani (Fowler), comb. n.

In its general form and size this species is not unlike U. notivena Walker from Malacca (185 la : 88), but differs from Walker's type very markedly in the separate 126 R. G. FENNAH submedian frontal carinae (which unite at middle in notivena), antennal proportions and in colour pattern. From the Sumatran intercepta Walker it differs in the separate submedian carinae, and indeed in the shape of almost every bodily feature, and from insularis Muir (192611 : 398), from the Mentawi Islands, it differs entirely in colour pattern, insularis being characterized by three longitudinal fuscous lines on the frons and fuscous front and middle legs. The two species differ also in the structure of the male genitalia. The Christmas Island species U. aristella (Kirby) (igooa : 136) has a proportionately longer vertex than nesiotes, and the lateral margins of the frons are sinuate, not simply convex ; at each lateral margin of the pronotum there is one distinct carina and a second distinct for the anterior part of its length. This and the present species differ abundantly in colour pattern. 29 FIGS. 24-30.

This species belongs to the percheronii group, and differs from all other species of this group in bodily proportions, colour pattern and apparently in the position of the union of the submedian carinae on the frons. In this feature it agrees with U. percheronii, but differs from this species in the presence of a fuscous band on the tegmina, which are immaculate in U. percheronii. Ugyops cassander sp. n.

This species is a member of the percheronii group, but is distinguished by the broadly fused submedian carinae on the basal three-quarters of the frons, by the relative proportions of the antennal segments, and by the colour pattern. It bears a resemblance to U. liturifrons (Walker), (iSyoa : 119), the type of which is from Gilolo, but differs in the shape of the head in profile, and in the median carina of the frons, which in the present species consists basally of a broad thickened eminence, whereas in liturifrons it takes the form of two distinct carinae on an elevated ridge. In colour pattern of the frons the two species differ markedly, liturifrons having a regular pattern of four rows of small dark spots alternated with light spots. NEW SPECIES OF UGYOPS From U.flyensis Schmidt (i93ob : 12), to which it is probably fairly closely allied, it differs in the basally widened and thickened median frontal carina.

(N.H.). Paratypes, same data, 2 $ $. This species superficially is not unlike the sympatric U. sulcatus Muir (i93ib : 70), but differs in the consistently much darker frons, without the bold pattern of subcontiguous round spots found in sulcatus, in antennal proportions, structure of the male genitalia and in tegminal markings. The feature which perhaps most readily separates the two is the coloration of the lateral lobes of the pronotum : in U. sulcatus these are mostly stramineous or ochraceous, with only a little fuscous interpustular marking, as contrasted with the striking pattern of pallid marks on a dark ground shown in the figure of cheesmanae. This species is dedicated to Miss L. E. Cheesman, whose collections in the south- west Pacific have contributed much to our knowledge of the insect fauna of this area. Ugyops orestilla sp. n.

Cheesman), B.M. 1930-178, B.M. (N.H.). NEW SPECIES OF UGYOPS 135 This species is closely allied to U. brevipennis Muir from Tutuila (Samoa), and the two apparently occupy an isolated position, and can readily be distinguished from all known species by the form of the head, the great length of the rostrum, or the structure and coloration of the tegmina. From one another they can be separated by the relative length of the antennal segments, the second segment in U. brevipennis exceeding the first in the ratio i-i : i, and the basal segment being relatively more slender, the ratio of length to width at middle being 6 : i. Moreover in U. brevi- pennis the lateral margins of the frons (in anterior view) are more strongly incurved to the frontoclypeal suture. The two species differ also in the profile of the head.

This species belongs to the annulipes group, and of this the geographically nearest known member is U. butleri Muir (i925d : 221) from Netche, Mare. From this the present species differs in the pattern of marking on the frons, which in butleri consists of four narrow longitudinal fuscous stripes, two overlying the submedian carinae, which are separate and parallel, and two occupying the disc between the submedian carinae and the lateral margins. In the type specimen of U. butleri, the only one available for study, the post-tibiae are only two-spined laterally. FIGS. 100-106.

The number of teeth laterally on the post-tibiae alone would suggest a close affinity between this species and U. inermis Dist. and U. houadouensis Dist., and indeed they are closely similar in most respects, and undoubtedly form a natural group. All are known only from New Caledonia. The present species is nearer to U. inermis in the form of the frons, but this is relatively narrower than in inermis. The feature that readily sets U. menelaus apart from the others is the relatively much longer second antennal segment. This species also differs appreciably in the colour pattern of the frons. The three species are known only from the respective male holotypes. The male genitalia have not been dissected, but it was evident from superficial examination that those of U. menelaus differ from those of the others in the detailed shape of the margin of the pygofer, as well as in the profile of the apex of the anal segment.

ELMO HARDY SYNOPSIS Only twenty specimens of Tephritidae were collected by the British Museum (Natural History) Expedition to East Nepal, 1961-62. This small group, however, contained four subfamilies, six tribes, nine genera, and eleven species ; six of the species are apparently undescribed. THIS collection is a most important one since it represents the first information we have concerning the fruit fly fauna of this little known region and I am most grateful to R. L. Coe and the British Museum (Nat. Hist.) for having had the privilege of studying this interesting material. For the art work I am indebted to Mrs. Elizabeth Twigg-Smith Pfeffer.

Subfamily DACINAE Tribe Dacini C ALL ANT R A Walker Callantra Walker, 1860, Linn. Soc. Lond. (Zoo/.) 4 : 154. Mellesis Bezzi, 1916, Bull. ent. Res. 7 : 114. Calantra Hendel, 1914, Wien. ent. Ztg. 33 : 74. This genus, composed of approximately two dozen known species, is apparently confined to the Oriental and Pacific regions. These are wasp-like in appearance and are readily differentiated from other Dacini by the elongate, slender antennae (Text-fig, i) ; the second and third segments combined are about equal to the vertical length of the head, and the length of the entire antenna is greater than the combined lengths of the front and the face ; the first antennal segment is equal in length to the second and at least half as long as the face ; and by the strongly clavate and petiolate abdomen, which bears a prominent hump on each side of the first segment (Text-fig. 4). Type species : Callantra smieroides Walker. Callantra nepalensis sp. n. (Text-figs. 1-5) This species appears to be related to C. munroi Rab (1961) but differs by having two superior fronto-orbital bristles rather than only one ; by having one strong anteroventral spine on each front femur, rather than three stout ventral bristles ; by having a longitudinal, brown to black median vitta extending over terga three and four separating off two large yellow submedian spots on tergum four, rather than having a single large pale spot occupying the greater portion of the fourth tergum. Also the female ovipositor is much shorter and less conspicuous in nepalensis (Text- fig. 3) than in munroi (cf. fig. 2 in Rab, 1961). In the description of munroi, Rab states that the ocellar bristles are black. This is probably an error since this group should possess no ocellar bristles, and his drawing shows none. $. Head. As seen in lateral view the head is distinctly higher than long and the compound eye is rather elongate (Text-fig, i). The front is about equal in width to the compound eye. The frontal bristles are very weakly developed, small and setae-like, two superior fronto- orbitals are situated, at about the upper one-fourth of the front and one inferior fronto-orbital is located just below the middle (note : on one side a tiny black seta is also present near lower portion of front in the specimen at hand) . The vertical bristles are well developed, the outer is subequal to the inner. The front is predominantly yellow with a transverse grey-black streak extending across the median portion and with a velvety black mark on each side at the lower edge of the front. The vertex is tinged with brown and the ocellar triangle is shining black. The face is yellow except for a polished black band extending along the lower margin. A faint indication of a brownish discoloration is present at the lower portion of each gena. The occiput, mouthparts, and palpi are yellow, the latter lack bristles or prominent setae. The antennae are 150 D. ELMO HARDY rufous, tinged with brown. The first two segments are approximately equal in length, the third is almost equal to the two basal segments (Text-fig, i). Thorax. Predominantly rufous, brightly marked with yellow on the humeri, on the suture, the notopleural calli, the scutellum, the posterior one-third to two-fifths of each mesopleuron, the major portion of each metapleuron, and with a spot of yellow at the upper median edge of each sternopleuron. A faint indication of a median yellow mark is present, extending from behind the suture about halfway to the hind margin of the mesonotum. The anterior margin of the scutellum is narrowly bordered with black. The metanotum is shining black on the sides and a vertical streak of black extends through the median portion of each mesopleuron ; the front portion of the mesopleuron is yellow, tinged with rufous. Only the postalar bristles are developed on the mesonotum except for the small notopleural bristles. One pair of small scutellar bristles are present. These are approximately equal in size to the posterior supra-alars. The scutellum is approximately three times wider than long. Legs. Predominantly rufous, tinged with brown.

DIPTERA FROM NEPAL 151 mid and hind femora are pale yellow. The hind femora are blackened ventrally. The tarsi are yellow, tinged with brown. The legs are yellow pilose. Each front femur has one strong posteroventral spine at about the apical third of the segment plus a small black bristle (Text- fig. 2). Wings. With a broad yellow-brown band along the costal margin, extending across the wing into the upper one-third to one-half of cell R 5 (Text-fig. 5). The second, third and fifth costal sections are approximately equal in length ; the fourth costal section is approxi- mately one-fifth longer than the others. The r-m cross-vein is situated near the middle of cell ist M 2 and is rather strongly curved. The cubital cell is developed into a long slender apical point which is approximately equal in length to the basal portion of the cell (Text-fig. 5). Abdomen. Very strongly petiolate, predominantly red, tinged with brown and densely white pilose, especially on the sides. The base of the first tergum is yellow, the apex of the second is yellow, and a pair of large yellow submedian spots are present on terga four and five, these are separated by a median brown to black vitta (Text-fig. 4). The ovipositor is short, inconspicuous, mostly concealed within the ventral concavity of the abdomen and protrudes but a short distance beyond the margins of the terga (Text-fig. 3).

This genus is readily recognized by the bare vein R i+5 ', by having only two scutellar bristles ; and by having the r-m cross-vein situated well beyond the middle of cell ist M 2 . The only previously recorded Oriental species is O.formosae (Hendel), which was placed in this genus by Shiraki, 1933 : 358. This combination was also listed by Chen (1948 : 70). Type species : Aciura tibialis Robineau-Desvoidy. Oxyaciura monochaeta (Bezzi) comb. n. (Text-figs. 6-9) Aciura monochaeta Bezzi, 1913, Mem. Indian Mus. 3 : 150, pi. 10, fig. 54. Bezzi allied this species to Aciura xanthotricha Bezzi but said that monochaeta differed by having the post-vertical and superior fronto-orbital bristles black, the median portion of the front very sparsely haired, and the ovipositor narrow and equal in length to the abdomen ; rather than having the post-vertical and the superior fronto-orbital bristles pale yellow, the front clothed with short and thick whitish hairs, and the ovipositor broader, shorter than the abdomen in xanthotricha. As noted above, it is probable that the latter species also fits in the genus Oxyaciura. This species is readily recognized by the generic characters, by the distinctive wing markings (Text-fig. 7), the predominantly black coloration, and the long ovipositor of the female (Text-fig. 9). 152 D. ELMO HARDY The antennae are yellow, the third segment is three times longer than wide. The aristae are distinctly pubescent. The palpi are entirely yellow, thickly setose around the margins. The head bristles are entirely black. The ocellar and postocellar bristles are short, approxi- mately two-thirds as long as the superior fronto-orbital bristles. The front possesses one pair of superior fronto-orbitals and three pairs of inferior fronto-orbitals. The front is yellow to rufous, tinged lightly with brown and rather thickly covered with yellow-brown pollen. The front is approximately equal in width to one compound eye. The head is shaped as in Text-fig. 6. The thorax is entirely polished black in ground colour, covered with grey pollen. The anterior dorsocentral bristles are situated slightly in front of a line drawn between the anterior supra-alars. The scutellar bristles are strong, approximately two times longer than the posterior dorsocentrals. The wings are marked as in Text-fig. 7. The coxae and femora are predominantly dark brown to black, tinged with yellow on the apices of the first two pairs. The tibiae and tarsi are yellow.

Tephrostola Bezzi, 1913, Mem. Indian Mus. 3 : 153. The genus is readily recognized by its broad wings with distinctive wing markings and by the presence of two costal bristles at the apex of the subcostal vein. Type species : Platensina sumbana Enderlein. Platensina zodiacalis (Bezzi) (Text-figs. 10-11) Tephritis zodiacalis Bezzi, 1913, Mem. Indian Mus. 3 : 163, pi. 10, fig. 65. This species was badly misplaced by Bezzi and should actually have fitted in his genus Tephrostola (1913 : 153), which is a synonym of Platensina Enderlein (cf. Hendel (1915 : 461) and Hardy (1959 : 208)). This species is differentiated from other Platensina by the distinctive wing markings as shown in Text-fig, n and by having only two scutellar bristles developed. The head excepting the compound eyes is yellow, covered with brownish yellow pollen over the front. The front is approximately equal in width to one compound eye and has numerous small, flat setae in the middle just above the lunule. Two superior fronto-orbital and three inferior fronto-orbital bristles are present. A small dark brown to black spot is present at the base of each frontal bristle (excepting the upper superior fronto-orbitals), and a small brown to black streak is present on each side at the extreme lower margin of the front, opposite the bases of the antennae. The antennae are yellow, the third segment is one and one-half to two times longer than high and is straight on the upper margin (Text-fig. 10). The aristae are conspicuously pubescent. The mouthparts and palpi are pale yellow-white, the palpi are very sparsely setose along the upper margin. As seen in lateral view, the head is shaped as in 0.6mm. FIGS. 10-11.

The pleura are largely rufous, tinged with brown in ground colour and densely grey-pubescent. The metanotum is black, covered with grey pollen. The legs are entirely yellow. Each front femur has three rather strong posteroventral bristles on the apical two- fifths of the segment. The wings are as in Text-fig, n. Two prominent costal bristles are present. The abdomen is predominantly polished black, discolored with yellow in the median portion of the first tergum and with yellow markings on the sides of the first four terga.

Indian Mus. 3 : 119. This genus is differentiated by the plumose arista ; by having vein /? 4+5 setose ; by the middle tibia having only one apical spine ; the third antennal segment rounded at the apex ; the ocellar bristles strongly developed ; two or three inferior fronto-orbital bristles present ; and the wings with characteristic transverse bands. This genus shows close relationship to Gastrozona and is separated largely on the basis of the strong orbital bristles. Apparently the number of inferior fronto- orbital bristles is somewhat variable ; the type was reported to have two inferior fronto-orbitals and several of the species described by Hering have been reported to have three inferior fronto-orbitals. It is probable that Taeniostola gracilis Bezzi (1913 : 120) does not actually fit in this genus since this species has only one inferior fronto-orbital bristle and only two scutellar bristles. The genus is presently known from five species from the Oriental region and one from Borneo. Type species : Taeniostola vittigera Bezzi. Taeniostola limbata Hendel (Text-figs. 12-17) Taeniostola limbata Hendel, 1915, Ann. hist-nat. Mus. Hung. 13 : 435, pi. 8, fig. 3. This beautifully marked species is readily recognized by the pattern of markings on the wings (Text-fig. 13), on the thorax (Text-fig. 14), and on the abdomen (Text- fig. IS)- The species is predominantly yellow, the mesonotum has four longitudinal vittae extending the entire length of the segment ; the lateral vittae are slightly interrupted at the suture. DIPTERA FROM NEPAL 155 The scutellum has a prominent black spot in the middle between the apical scutellar bristles. The metanotum is polished black and a shining black spot is present on each pleuron behind the wing base. The anterior dorsocentral bristles are situated slightly behind a line drawn between the anterior supra-alar bristles. The ocellar bristles are stronger than the orbital bristles and are three-fourths as long as the inner verticals. Two strong superior fronto-orbitals and two strong, plus one weak pair of inferior fronto-orbitals are present (Text-fig. 12). The outer vertical bristles are approximately equal in size to the superior fronto-orbitals and the postocellar bristles are approximately equal in size to the anterior supra-alar bristles. The antennae are entirely yellow ; the first and second segments are fringed with black setae around their apices and a prominent black bristle is present on the dorsal surface of the second segment. 14 FIGS. 12-17.

Each front femur has a prominent row of posteroventral bristles extending the entire length of the segment ; also the posterodorsal surface is strongly setose. Each middle femur has two black postero- ventral hairs near the apical third of the segment, and the hind femur has two black postero- ventral hairs at the middle. The middle tibia has one strong apical spur, this is almost two-fifths as long as the basitarsus. Wings with two almost complete transverse bands plus two brown streaks ; the base of the subcostal cell is black, the remainder of the cell is yellow, this extends as a yellow band transversely across the wing, ending in the apex of the cubital cell. A brown band extends along the wing margin from near the middle of cell R l to the middle of cell R 5 and transversely across the wing at a level with the y-m cross- vein, ending at the apex of vein Cu^-}- ist A . An oblique streak of brown extends through cell R & just beyond the middle and ends at the wing margin near the tip of cell 2nd M 2 . A brown streak also extends across the wing from cell R & just above the m cross-vein, over the ra cross-vein and expands at the wing margin in the apex of cell M 4 (Text-fig. 13). The r-m cross- vein is situated distinctly beyond the middle of cell ist M 2 . The apex of the cubital cell is drawn out to a slender point. The first two abdominal segments are entirely yellow. A broad black basal band extends across each of terga three and four in the male (Text-fig. 15). The fifth tergum of the male is entirely shining black except for a yellow spot in the middle at the apex. The sixth tergum is not visible in the male but the ninth segment is plainly visible when the abdomen is tilted slightly. The ninth is shining black over the dorsum, yellow on the sides and on the ventral lobes. The ventral lobes are slender, slightly enlarged at apices and developed into two blunt points (Text-fig. 16). The claspers are hidden from lateral view, each is developed into two blunt, black apical points. The cerci are large, densely setose. (The genitalia have been described from specimens from India.) Length : Body, 8-5 mm.; wings, 9-0 mm. (Hendel recorded this species as body and wings, 8-0 mm. long.) In the female (specimens from India), terga three to five are rather narrowly bordered with black along the posterior margin and the sixth tergum is plainly visible from dorsal view but is only about one-third as long as the fifth. The sixth is entirely black. The base of the ovipositor is slightly longer than segments four plus five. When fully extended the ovipositor, including the base, is 7-4-8-0 mm. The piercer measures 2-7-2-85 mm. ; is one-fourth longer than the base and blunt at apex (Text-fig. 17). Type locality : FORMOSA. The type is in the Natural History Museum, Vienna. This species was recorded from INDIA by Munro (1935 : 17). It is common in northern India. I have seen numerous specimens from the foothills of the Himalayas in the vicinity of Ranikhet and Chaubattia. E.

DIPTERA FROM NEPAL 157 Only nine species of Chetostoma have been recorded previously ; two from Europe including Russia, two Nearctic, three from China, one from Burma and one from Japan. This genus is characterized by having a clump of prominent black setae or bristles on the lower portion of each gena (Text-fig. 18) ; by having three pairs of inferior fronto-orbital bristles ; the r-m cross-vein situated before the middle of cell ist M 2 ; and vein ^ 4+5 setose to beyond the r-m cross-vein. Type species : Trypeta giraudi Frauenfeld. Chetostoma interrupta sp. n.

The ocellar setae are black, well developed, one-half to two-thirds as long as the postocellar bristles. The face is entirely yellow-white and has a very slight raised area down the median portion. The palpi and mouthparts are yellow-white. Each palpus is thickly black-setose around the outer and apical margins. The antennae are predominantly rufous, the second and third segments are tinged with brown along their upper and apical margins. The second segment has one rather prominent dorsal bristle and numerous black setae around the apex. The third segment is rounded at the apex and slightly over two times longer than wide. The arista is pubescent. The head is shaped as in Text-fig. 18. Thorax. Predominantly polished black in ground colour, rather densely grey-pollinose, subshining on the pleura and with a polished area in the middle of each sternopleuron, also a polished black spot is present in the middle of the metanotum. The humeri, propleura and front margin of each mesopleuron are yellow, tinged faintly with brown. The hind margin and the ventral portion of the scutellum is yellow. The anterior dorsocentral bristles are situated approxi- mately in line with the anterior supra-alars. The mesonotum is densely black-setose. The scutellum is bare except for a few tiny hairs around the margins and for the four strong bristles. The halteres are pale yellow. Legs. The front legs are entirely yellow except for a discolora- tion of brown to black along the posterior surface of each femur. On the middle and hind legs the coxae are brown to black, tinged faintly with yellow. The trochanters are yellow, tinged with brown. The femora are predominantly black, yellow at their apices and on the apico- ventral half of the middle pair. The tibiae and tarsi are yellow except for a tinge of brown to black on the hind tibiae. Each front femur is rather densely bristled over the posterior surface (Text-fig. 19). The middle femur is conspicuously flattened down the ventral surface. Each hind tibia has a rather prominent row of black anterodorsal bristles extending the entire length of the segment. Wings. The basal cells are brownish yellow fumose, this marking extends longitudinally through the wing to connect, in cell ist M z , with the dark brown transverse mark which extends across the wing at a level with the subcostal cell and the r-m cross- vein. The pale marking is interrupted by a large hyaline spot situated in cell R just beyond the forking of veins R 2+3 and R i+5 . The subcostal cell is entirely dark brown except for pale yellow-brown fumosity at the extreme base of the cell. A narrow transverse mark extends from the costa at about one-third the distance between the apices of veins ^? x and 7?2+ 3 , across the cells 7? x and R 3 , ending at vein M 1+2 well beyond the r-m cross-vein. A complete transverse band extends across the wing from the costal margin just before the apex of cell R! to the apex of cell M 4 at a level with the m cross-vein. A prominent brown mark is present at apex of cell R 3 and extends over into the upper apical portion of cell R 5 (Text-fig. 21). The r-m cross-vein is situated distinctly before the middle of cell ist M 2 . The fourth costal section is one-half longer than the fifth and almost four times longer than the third section. Vein R t+5 has eight to ten black setae, one of these is situated beyond the r-m cross-vein. Abdomen. Polished black in ground colour, densely grey-pollinose except for a polished black area extending around the sides and apex of the fifth tergum. The abdomen is thickly black- setose and has prominent black bristles on the apical margins of terga three to five. The genitalia are black, tinged with yellow to rufous on the lower margins of the ninth segment and with the cerci yellow, tinged rather faintly with brown. As seen from a lateral view the genitalia are as in Text-fig. 20. The ventral margins of the ninth segment are elongated, extended on each side into a slender ventral lobe. The claspers are long, rod-like and each terminates in two blunt, black finger-like points. The cerci are nearly oval, very densely setose. Several strong bristles are present on the top margin of the ninth segment. Length : Body, 3-5 mm.; wings, 6-2 mm. $. Unknown. Holotype <$. E.

This genus is differentiated by having vein -R 4+5 bare or with only two or three setae at base ; by having the third antennal segment pointed at upper apex ; by the hind femora having several long antero- ventral hairs or bristles before the apex ; by having the ovipositor base very short, not longer than the sixth abdominal segment ; and by having the eyes comparatively high and narrow. About three dozen species of this genus are known, these range throughout the Holarctic and Neotropical regions but are predominantly temperate climate species. The larvae live in fleshy fruits, nuts, and in rose hips. It should be noted that Stone (1951 : 47) followed Hendel (1927 : 74) in treating Zonosema Loew as a synonym of Rhagoletis. Rohdendorf (1961 : 177) treats these as distinct genera. Type species : Musca cerasi Linnaeus. Rhagoletis rumpomaculata sp. n. (Text-figs. 22-26) This species runs to Rhagoletis in Hendel (1927 : 20), Zia and Chen (1938 : 9), and Chen (1948 : 82). In the latter two works it runs nearest to reducta Hering, from China, but the wing markings are strikingly different. In Rohdendorf 's key to the Palearctic species of the genus Rhagoletis (1961 : 178) this runs to almatensis sp. n. from South Kazachstan, U.S.S.R., but again the wing markings are very different. The species is readily differentiated from any Rhagoletis known to me by the broken pattern of the markings in the apical half of the wing ; the bands are completely disrupted, broken into scattered spots (Text-fig. 26). The front femora are more distinctly bristled than in most species which I have seen (Text-fig. 23). $. Head. As seen from direct lateral view the face is vertical and the lower portion of the occiput is rather swollen so that at its broadest point the occiput is almost one-half the width of the compound eye (Text-fig. 22). Three strong pairs of cruciate inferior fronto-orbital bristles and two pairs of reclinate superior fronto-orbital bristles are present. The ocellar bristles are strong, approximately equal in length to the inferior fronto-orbitals. The post- ocellar bristles are pale brownish yellow and are about two-thirds as long as the ocellar bristles. The vertical bristles are well developed. The occipital setae are pale brown, long and slender. The antennae are yellow, tinged faintly with brown, the third segment is distinctly pointed on the upper apical margin (Text-fig. 22). The arista is bare or nearly so. Thorax. Predomi- nantly brown to black in ground colour, densely grey-pollinose and with abundant black setae over the mesonotum. The scutellum is predominantly yellow, tinged with brown, the basal margin is black. The humeri are yellow, tinged with brown and each pleuron is tinged with rufous in the median portion. The propleura and the front margin of each humerus are densely white haired. The anterior dorsocentral bristles are situated approximately opposite the anterior supra-alars. Four strong scutellar bristles are present, these are slightly greater in i6o D. ELMO HARDY length than the dorsocentral bristles. The halteres are yellow. Legs. Entirely yellow. The front femora are densely setose and each has a row of strong posteroventral bristles extend- ing the full length of the segment (Text-fig. 23). Each hind femur has several anteroventral bristles before the apex of the segment. Each hind tibia has a prominent row of anterodorsal bristles extending the full length of the segment (Text-fig. 24). Wings. With an incomplete brown marking extending across the base ; a broad brown mark extending transversely from the costa, filling all of the third costal section (cell Sc) , across the wing into the middle of cell M 4 ; also with a single transverse streak across the middle of cell J R 1 ; another brown mark at the apex of cell R t which extends transversely across vein R t+5 into cell R 5 ; another brown spot is present at the apex of vein ^4+5 ; another is present in the upper median portion of cell R 5 ; a spot is present near the median portion of the last section of vein M l+2 ; and one is also present on each end of the m cross-vein as in Text-fig. 26. Vein R : is setose throughout its entire length. Vein R t+5 has two small setae at its base. The r-m cross-vein is situated at the middle of cell ist M z . The cubital cell is sharply pointed at the apex. Abdomen. Predominantly polished black in ground colour, lightly grey-pollinose, each tergum has a distinct yellow band along the posterior margin. Moderately strong bristles are present on the posterior margins of the terga, especially five and six. Tergum six is approximately one-half as long as five. The ovipositor is short, rather inconspicuous, as seen in situ the visible portion is approxi- mately equal to abdominal segments five and six (Text-fig. 25). Length : Body and wings, 5-7 mm. cJ.

Subfamily TEPHRITINAE Tribe Tephritini ACTINOPTERA Rondani Actinoptera Rondani, 1871, Bull. Soc. ent Ital. 3 : 162. This genus is readily recognized by having only one pair of superior fronto-orbital bristles, only two scutellar bristles, and by having the anterior dorsocentral bristles situated opposite the suture. This is predominantly a European genus, though two species have been recorded from China (Zia and Chen, 1938 : 95), one has been recorded from Formosa (Shiraki, 1933 : 447), and one new species is being described from Japan by Dr. S. Ito in a monograph of the Japanese fruit flies (in press) ; I am recording the latter species also from Nepal. Type species : Tephritis discoidea Fallen. Actinoptera sp. n. (in Ito manuscript, in press) (Text-figs. 27-28) sp. n. Ito (in press), Beitrag zur Systematik der Japanischen Trypetiden Actinoptera (Diptera) . I have had access to Dr. Ito's manuscript and feel certain that the species here recorded from Nepal is the same as the one he is describing as new from Japan. This species rather closely resembles A . discoidea (Fallen) from Europe but the wing 28 FIGS. 27-28. Actinoptera sp. n. being described by Ito. 27. head, lateral ; 28. wing. 162 D. ELMO HARDY markings differ. The most striking character for separating the new species is the presence of three hyaline marks in cell Rj^ beyond vein R 1 rather than two, as in discoidea, and by the presence of a faint brown streak extending across the middle of the second costal section. This is a densely grey-pollinose species with all yellow legs, halteres, antennae and mouthparts. It is being adequately described by Dr. Ito. The profile view of the head is as in Text-fig. 27 and the wings are as in Text-fig. 28. Length : Body, 2-5 mm. ; wings, 3.0 mm. It should be noted the specimens from Nepal are slightly shorter than those which will be recorded from Japan by Dr. Ito. His specimens measured : Body, 3-0 mm. ; wings, 3-5 mm. E.
