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 : 331- (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 I4 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 and 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 R2 and Rt very long and narrow, R2 with a short footstalk, Rt 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 M3 stalked. Veins Cu1 and Cuz run separately into the wing margin, fork Cul& sessile. Vein Cu2 with a row of stout setae about midway on the under surface. Hind wing with Rt terminating in Sc, a faint cross-vein between it and R2+3. Apical forks Rt and Ml stalked, Cwla sessile. cj GENITALIA. 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 Cu2 in the fore wing. The venation recalls that of the Agapetinae, but in this subfamily stout 38 D. E. KIMMINS setae on or near Cu2 in the fore wing are unknown and there are always warts on the mesoscutellum. Apical fork Cula is usually lacking in the Protoptilinae, where Cu± and Cu2 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 R5 (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 M2 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 Ri+5 ', by having only two scutellar bristles ; and by having the r-m cross-vein situated well beyond the middle of cell ist M2. 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. Length : Body, 3-75 mm.; wings, 4-3 mm. by approximately 2-15 mm. in width. The above description is based upon a single male specimen. The species has been previously recorded only from INDIA.

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 Rl 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 M2. 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 M4 (Text-fig. 13). The r-m cross- vein is situated distinctly beyond the middle of cell ist M2. 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.

I use the original spelling by Rondani for this genus. 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 M2 ; and vein ^4+5 setose to beyond the r-m cross-vein. Type species : Trypeta giraudi Frauenfeld. Chetostoma interrupta sp. n.

The lower margin of each gena is thickly covered with short, black bristles as in Text-fig. 18. The gena is about one-fifth the height of the eye. The front is predominantly yellow, discolored with reddish brown and covered with yellow-grey pollen. The median portion of the front is sparsely black-setose.

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 Mz, 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 R2+3 and Ri+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 R3, ending at vein M1+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 M4 at a level with the m cross-vein. A prominent brown mark is present at apex of cell R3 and extends over into the upper apical portion of cell R5 (Text-fig. 21). The r-m cross-vein is situated distinctly before the middle of cell ist M2. The fourth costal section is one-half longer than the fifth and almost four times longer than the third section. Vein Rt+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 -R4+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.

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.

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.

The most striking character for separating the new species is the presence of three hyaline marks in cell Rj^ beyond vein R1 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.

REVISIONAL NOTES ON AFRICAN CHARAXES 225 with many food plants has split up into ecological groups each covering wide areas, but which are linked together, in minor degree by " clines "! It is of interest to note that although van Son (1953 : 219, 221-2) places all kenneihi as merely a form of the nominotypical Natal race, he places maudei Joicey & Talbot from an area intermediate between Natal cithaeron and true kennethi, as a race of cithaeron. However, I am satisfied that maudei is not a race of cithaeron, but of xiphares, and that kennethi and maudei occur together on the Usambara Range, at Amani, in Tanganyika (see pp. 233 and 206). Dr. van Son has pointed out that in contrast to the general habitat of xiphares which frequents higher cool evergreen forests, cithaeron is found in the low tropical forests of the coast belt and hinterland, and in patches of savanna and gallery forest, thus inhabiting a diversity of forest types. Moreover, the range and diversity of its food plants is very considerable. The following food plants are recorded : — In southern Africa : Albizia (2 species), Acacia sp., Baphia sp. (LEGUMINOSAE) ; Celtis sp., Chaetacme sp., Trema sp. (ULMACEAE). In Kenya and Tanganyika : Afzelia sp., Crabia sp., Albizia sp. (LEGUMINOSAE) ; Gymnosporia sp. (CELASTRACEAE) ; Hippocratea sp. (HIPPOCRATEACEAE) ; Grewia sp. (TILIACEAE). All these plants are very widespread and are associated with most forest types, and it is surprising therefore that the species cithaeron has such a comparatively restricted range, and, so far as is known, has not extended into the north-west of Tanganyika nor into the Congo. In some areas of its range, the countries are subject to marked wet and dry periods, and it is not surprising to find some degree of seasonal variation in cithaeron and I shall refer to this later. Through the willing co-operation of many correspondents, I have been able to bring together a very large amount of material representative of the species through- out its known range ; these include the eastern Cape, and Natal, southern Mozam- bique, Southern Rhodesia, Nyasaland and Northern Rhodesia, southern and eastern Tanganyika and Kenya. In analysing this material into groups, I have been guided by what appears to be the predominant characters of each, in both sexes, and the stability of them. In every group there are variations, tending one way or another and some evidence of seasonal modification. In the descriptions which follow I have selected fresh examples exhibiting constancy of the chief characters, and where minor differences occur, these are mentioned. I shall also refer to, and wherever possible figure, outstanding variations within the series. Charaxes cithaeron cithaeron Felder (PI. 19, figs. 133, 134, 136, 137 ; PI. 20, figs. 138, 139) Charaxes cithaeron Felder, 1859 : 398, pi. 8, figs. 2 <$, 3 ?. Charaxes cithaeron Felder ; Rothschild & Jordan, 1900 : 379. A detailed description of the species is given by Rothschild & Jordan (1900 : 379), based presumably on south African material, but since the range of the species is 226 V. G. L. VAN SOMEREN given as " from Natal northward to Nyasaland, German and British East Africa " it may include material subsequently separated off as distinct subspecies. It is thought that a redescription of topotypical Natal material is desirable. MALE. Fore wing length 41-45 mm., majority 43-44 mm. Upperside. Ground colour blue-black with a strong blue sheen mainly on basal half ; fore wing costa brownish on basal portion ; two rows of comparatively small blue spots, discal and post-discal ; the spots in the former are two elongate beyond end of cell (very rarely a trace of a subcostal blue line), spots in 3-4 more rounded and set out distad, spot in 2 usually vestigial, often absent ; usually no spot in ib, but if present rather diffuse ; elongate blue line in la on hind margin usually free, but may be contiguous to, but not fused with post-discal spot above ; post-discal spots run parallel to outer margin of wing and are comparatively small ; subapical spots white, remainder blue, often vestigial. Hind wing black, slightly shot with blue distally, but dull toward base ; inner fold blackish at base shading to greyish at anal angle ; discal light patch comparatively narrow, whitish on inner half toward fold but strongly bluish above and distally, extending from 4-5 where it is narrow, then widening towards inner fold, sometimes represented in 5 by a rounded, separate or contiguous, blue spot and by a whitish-blue subcostal spot rather diffuse or often absent ; submarginal row of blue spots, angular or elongate, double at anal angle, becoming small and separate or fading out toward upper angle ; marginal lunules buff to ochreous, more greenish at anal angle separating toward upper angle ; fringe narrowly white, broken by ends of veins ; margin dentate ; tails long and thin, upper 5-8 mm. (seldom longer), lower 3-4 mm., black edged, centre line buff. Underside. Light greyish-olive with a slight tawny bloom over base of fore wing and disc of hind wing ; black transverse lines at base fore wing fairly constant as regards position but varying in thickness ; sub-basal bar in cell almost straight, second and third bars slightly angled ; a double bar at end of cell ; thicker sub-basal bars in ib and 2 almost straight or crescentic ; a zigzag black line outlines the inner edge of the irregular ochreous-olive discal bar ; the post-discal marks of upperside here repre- sented by two whitish subapical spots followed by rounded or lunate ochreous marks increasing in size, the lower ones encircling the tornal black spot and the one above ; the tornal mark somewhat kidney-shaped, indented on the outer aspect ; ochreous marginal spots complete but small. Hind wing basal lines thin, usually double and enclosing ochreous ill-defined bands, that in sub-basal area of subcostal in 8 almost straight, that in 7 set out and contiguous with marks crossing cell and somewhat S-shaped, and not extending into ic ; a discal zigzag narrow black line runs along the inner edge of the more ochreous-olive discal line ; post-discal spots ochreous, dusky on outer aspect and increasing in size from costa to anal angle, are mostly crescentic, that at anal angle double ; submarginal spots, purply-mauve proximally, are increasingly purply-black distally terminating in double spot at anal angle ; marginal lunules ochreous with increasing green scaling between tails and anal angle. FEMALE. Fore wing length 44-50 mm., somewhat variable, usually about 48 mm. Upperside. Ground colour blue-black on distal portions, bluer along proximal edge of fore wing white band ; browner toward base ; (old specimens are generally browner, especially in basal area). Fore wing discal white band curved, extending from costa to hind margin ; outer border more evenly curved than inner, white scaling on costa extending basad for about half its length ; three elongate white marks at end of cell, middle one longest and projecting distad, bases of all three in a line ; spot in 3 bluntly triangular and set out from spot above at about mid point, its outer border oblique ; spot in 2 more elongate, proximally rounded and in line with spot above, but outer oblique edge continuous with that above and in same line ; mark below shorter, outer edge in line with one above but inner edge reaching to about middle only, while the lower marks in ib and mark in la extend proximad, the last three at an angle to spots above, so that the inner border of the discal band has a marked double kink, at vein 2 and in line with the lower arm of the cell ; the distance of the band in xa-ib from the tornal margin is wide, though slightly variable, usually 7-10 mm., often the latter. The white mark in la may be slightly blue scaled ; postdiscal spots variable in number, but always with two large REVISIONAL NOTES ON AFRICAN CHARAXES 227 subapical, white or buff, the spots in 4-3 if present rather indistinct ; margin with hardly any indication of spots, but there may be two at tornus. Hind wing with large bluish-white discal patch shaded with bluish-violet scaling distally, inner border almost straight but rather diffuse, usually represented on the subcosta by one discrete spot or two contiguous spots, outer border of patch more curved and merging into the inner fold above anal angle ; discal patch variable in width, but on an average is 10-11 mm. wide in area 4, but is often considerably narrower. When the band is narrow, there may be an indication of whitish post-discal spots in 3-4. The submarginal row of rounded or triangular blue spots with white centres may be complete or fading out at upper angle ; marginal ochre lunules may be contiguous or separate, fading out at upper angle ; marginal black with hardly any indication of a white fringe ; tails mostly black, thin, variable in length, upper 6-10 mm., lower 4-6 mm. Underside. As in the male but fore wing discal band well marked and stopping short in ib ; the black lines more developed ; post-discal lunules of hind wing often more strongly marked ; zigzag discal line may be strongly edged whitish, almost forming a bar, but is usually narrow. Variations. FEMALES. An extreme variant may have the streak in la of discal bar only just indicated while the two spots in ib are reduced to small dots, the discal bar is thus incomplete and shortened in its posterior portion. A further variant has the discal band complete but reduced to half the normal width, conversely a specimen from Dondo, Mozambique has an exceptionally wide fore wing discal band, the increase in width being due to an extension of the white marks in 2-3 basad, and reaching the cell, while that in ib is extended basad only slightly less. The proximal border of the band is far less indented and more evenly curved than normal. MALES. There is little variation in the upper side. A very small minority may have larger discal blue spots in the fore wing than normal, and the blue streak in la may link up with the lower spot in ib. In the hind wing the whitish blue patch may not be represented beyond cellule 4 and the light subcostal spot is absent. Range : The nominotypical race extends from Pondoland up the east coast to Natal, Zululand and Swaziland to Beira in south Mozambique (Dondo and Amatongas) then westward to the eastern side of S. Rhodesia. It has usually been presumed that the species has a continuous distribution through the northern part of Mozambique to Tanganyika and beyond, but I have been unable to trace any specimens of the nominotypical race north of the Zambesi Valley. Charaxes cithaeron joanae ssp. n. (PI. 20, figS. 140-145) The species cithaeron does not appear to have been recorded from the western half of Northern Rhodesia until recently, when a single male was captured and forwarded to me by Mrs. J. Wedekind of Mumbwa. Mumbwa is situated west of Lusaka in the bend of the Kafue River. The country thereabouts is largely savanna with small patches of riverine or gallery forest. The specimen aroused my interest for it appeared to differ considerably from other known races of the species and I urged my correspondent to try and obtain further material including females ; at the same time I drew Dr. Cottrell's attention to the capture. The species does not appear to be common in the area, but the result of the com- bined efforts of these two collectors has been the taking of a dozen males and females over a period of almost two years ; they substantiate the distinctness of this race. 228 V. G. L. VAN SOMEREN The male differs from the nominotypical Natal race by the larger spots of the fore wing both discal and postdiscal, by the larger more conspicuous marginal spots ; by the larger hind wing discal patch, larger submarginal spots and more conspicuous marginal lunules. The female differs in the fore wing by its wider more solid discal band, larger sub-apical white spots, more conspicuous marginal ochreous spots, and in the hind wing by the considerably larger discal patch, larger blue submarginal spots and broader marginal ochreous border. MALE. Fore wing length 38-45 mm. (Mumbwa specimens March-April average large, 45 mm. Chisamba, Lusaka area July, 45 mm., October-November, 38-43 mm. This difference in size combined with differing underside characters may be seasonal.) Upperside. Fore wing ground colour strongly blue-black with strong greeny-blue sheen at base ; discal spots arranged as in nominotypical cithaeron but always considerably larger, those in ib usually large and may be fused with the elongate blue streak in xa and usually touching the large post-discal spot in ib ; post-discal spots larger and well marked, subapical white spots larger, other spots blue ; marginal spots well developed, white or creamy. Hind wing basal areas black, distal border blue-black ; discal patch constantly wider than nominotypical specimens and strongly suffused with bright blue in upper and outer borders, whitish towards inner fold which is greyish to greyish-white ; the patch is represented at the costa by a white or bluish- white spot. Most specimens exhibit a series of white or ochreous-tinted spots on upper portion of outer border of the discal patch or along the entire border to just above the anal angle ; black border with well developed blue arrow-head marks, white centred ; marginal lunules orange-ochre separated by ends of black veins ; tails relatively short, upper 4-5 mm., lower 3-4 mm. Underside. Much duller and lighter (almost uniform ochreous putty-coloured in dry season specimens), less strongly patterned than in Natal specimens, the black lines finer ; the fore wing tornal occular spot smaller and almost or completely divided into two ; the post-discal dark line in hind wing is, however, more apparent against the paler ground. FEMALE. Fore wing length 47-52 mm., majority 50 mm. (There is some seasonal size variation as noted in the males.) The outstanding character of this race is the very wide, solid fore wing white band, and the large discal patch in hind wing. Upperside. Ground colour less blackish, the basal areas more brownish (fading to olive-brown in old specimens). Fore wing pattern much as in the nominate race but bolder, the discal curved bar uniformly wider throughout its length, the inner edge being less indented in area 3 due to spot there, being large and its base less set-out ; the three elongate marks beyond the cell longer and very frequently with a white streak subcostal in the cell ; white scaling on costa more extended ; the lower white blocks in ia-3 often with white scaling along the veins proximally, giving the inner border a " rayed " appearance ; post-discal series of spots often entire, the two subapical ones large, the upper one arrow-head in shape, the lower more rounded or oval, the remainder whitish or slightly tinted ochre, that in 2 contiguous with the discal mark ; discal bar in ia-2 extends much nearer the tornus than in the nominate race ; marginal spots clearly indicated, often large, double in ib, slightly ochreous. Hind wing discal patch very large, extending from the costa to the anal angle and on the inner border merging with the greyish of the inner fold ; inner border almost straight but diffuse, with a defined indentation at the costal spot, outer border more curved, with evidence of post-discal spots in 7-5, the upper one free, the others merging into the border of the patch ; centre of patch whitish but margins suffused with violet-blue to mauve scaling. The large size of the patch reduces the width of the outer black border which carries submarginal blue spots, large and well developed and in continuous series from upper angle to anal angle. Marginal lunules well marked, ochreous or creamy ; margin moderately dentate, and white fringe obvious ; tails thick at base, more robust than in Natal specimens ; length, upper 6-8 mm., lower 4-7 mm. Underside. There appears to be some seasonal variation in colour and markings : specimens taken during March-April at Mumbwa are boldly lined, those captured during August-November are very pale and lightly marked. REVISIONAL NOTES ON AFRICAN CHARAXES 229 Discal white bar of upperside here reproduced and extending to the hind margin ; post-discal spots rather diffuse ; dark tornal spot less marked and almost divided and reduced in size. Hind wing ground colour paler than nominate race, dark lines almost obscured, but post-discal ochreous marks with dusky distal scaling more obvious, but the marginal lunules may be obscured.

It may extend eastward and northward, in suitable localities. At present there appears to be complete separation from the Nyasaland race. Charaxes cithaeron nyasae ssp. n. (PI. 21, figs. 147-149 ; PI. 22, figs. 153-156 ; PI. 23, figs. 161-163) The general facies of this race bears some resemblance, especially in the females, to the T3.ce joanae of western Rhodesia. The females are, in the main, broad banded. The males exhibit a larger hind wing patch than in the Natal race and they are a brighter insect of comparatively large size. The male differs from the nominotypical race and from joanae by its brighter blue sheen especially on the forewings, the spots being larger than those of the Natal race but not so large as in joanae, and these spots having a more greeny-blue tone, especially on hind margin. The hind wing discal patch is larger than those of the Natal race, slightly smaller than in joanae but with a strong greeny-blue border on upper and outer sides and the marginal ochreous border conspicuous. The female is larger than Natal specimens as a rule ; the ground colour not so dark, the fore wing discal band wider, more solid but not so wide as in joanae ; the post-discal spots larger and more complete ; the marginal ochreous spots present but small ; hind wing discal patch large, shaded with lavender and with irregular outer border with post-discal spots visible ; the submarginal spots large, marginal ochreous border conspicuous ; the tails long. MALE. Fore wing length 43-48 mm., majority 45 mm. Upperside. Ground colour a brighter blue-black than typical Natal specimens, with a strong tinge of green sheen in basal area. The blue spots are, on an average, larger than in nominotypical cithaeron, but not as large as in joanae. The discal spots of fore wing are complete from costa to hind margin ; post-discal spots well developed and the line more inclined proximad in area 3 giving the line a distinct inward kink ; also the margin more concave ; two upper subapical spots white, remainder blue-green and in a majority of specimens discal and post-discal spots approximate or fused in ib ; margin of the wing with small but distinct creamy spots, occasionally these spots are as large as in joanae. Hind wing basal area black, inner fold ashy-grey ; the dark border with greeny-blue sheen ; discal patch comparatively large but does not extend towards costa so much as in joanae, but is represented by one discrete spot at costa and by one or two discrete post-discal spots ; upper and outer borders of the patch with strong greeny-blue 230 V. G. L. VAN SOMEREN suffusion, brighter than Natal specimens and this brightness is retained even in old specimens taken in 1928 ; black border with a complete series of submarginal blue spots, usually large, but sometimes small ; marginal lunules sometimes complete or usually divided by internervular rays, ochreous with some greeny scaling in the region of the tails and at anal angle ; tails thin and longer than in joanae, upper 6-7 mm., lower 4-5 mm. Underside. Ground colour colder darker grey, less brownish than Natal race, and much darker than the dry season form of joanae ; pattern as in nominotypical cithaeron, but post-discal row of fore wing spots slightly more kinked proximad as on upperside. FEMALE. Fore wing length 47-51 mm., mostly 50 mm. Upperside. As already stated, these females bear a resemblance to female joanae in that the fore wing is wide and the hind wing patch large. Fore wing discal white band less indented on the inner margin than Natal race, due to the larger marks in ib which extend proximad, and the frequent white scaling at end of cell ; streak in la suffused with blue as is proximal end of mark in ib, the conjoined marks here, being solid and hardly if at all indented on the distal end ; post-discal spots well developed, the supapical ones large and white, the remainder suffused with bluish and often present in 2 or even ib. Hind wing as in joanae ; discal patch large, extending up to the costa in discal row and often with a post-discal series of spots, free in subcostal area but merging into outer border of patch giving it a rayed or dentate outline, thus not so defined as in joanae, outer border strongly suffused with lavender-blue scaling ; dark distal border though relatively narrow is ill defined on its inner edge and carries a complete row of large lavender-blue white centred spots, these more bluish at anal angle ; marginal lunules creamy or ochreous, usually divided at mid point and separated by ends of dark veins ; white fringe strongly marked in most specimens ; tails moderate in length, upper 6-9 mm., lower 5-7 mm., mostly black, upper one with ochreous mid line. Underside. Ground colour as male but pattern bolder as a rule but variable ; discal and post-discal marks bold in fore wing, the former continued to hind margin. Hind wing discal and post-discal lines and spots bold, but may be suppressed on discal line. This variation may be seasonal. Variations. Although the vast majority of specimens exhibit a marked degree of constancy in pattern, one or two specimens of both sexes show a departure from the rule. Thus one male (PI. 21, fig. 149) exhibits a reduction in the size of the fore wing spots and an accompanying restriction of the hind wing patch. Two other males (PI. 22, figs. 153, 154) exhibit a fore wing pattern within the normal range but the hind wing patches are narrow and unusual and the undersides are abnormal. Females (PI. 22, figs. 155, 156), with a reduction in the fore wing and hind wing spots and discal patch suggest a trend toward the southern nominotypical race. Holotype male.

Through the kindness of Dr. Hannemann, I have been able to examine the type specimen described by Schultze from Manow, southern highlands Tanganyika, north of Lake Nyasa. REVISIONAL NOTES ON AFRICAN CHARAXES 231 Upperside. The specimen is normal in size and markings, but the ground colour of both fore and hind wings, instead of being blue-black is a curious semi-translucent brownish-black suggestive of a lack of development of melanin pigment in the scales. The underside ground colour is greyish-brown without olive shading ; the black lines are thin and the ochreous spots though present are not strongly indicated. The specimen is old, but the date of capture is not given on the data label. The tails are long and thin, upper 7 mm., lower 5 mm., thus consider- ably longer than in Ch. xiphares brevicaudatus Sch. which also occurs in the Manow area and which bears a superficial resemblance to cithaeron. I have seen no other specimens from north of Lake Nyasa, but this specimen seems to fit in with cithaeron nyasae from Lake Nyasa, and is placed to this race. Range : From the north-western shores of Lake Nyasa at Nkata Bay 1,800 ft. south to the region of Zomba and the foothills of Mlanje, and neighbourhood. I have no records of the species from the eastern shores of Lake Nyasa. Charaxes cithaeron kennethi Poulton (PI. 22, figs. 157, 158 ; PL 23, figs. 164-168) Charaxes cithaeron kennethi Poulton, 1926 : 539. This subspecies was accepted as valid up to 1953 when Dr. van Son suggested that the nominotypical race extended " over the whole eastern coastal area from Pondoland to Kenya " and that kennethi was but a wide banded female form to be found in the southern areas of nominate cithaeron. I have already commented on the evidence he adduces in support of his views, in the introduction to this section, and would here add that Dr. van Son appears to have based his views mainly on the female, disregarding the male of the race. MALE. Fore wing length 44-47 mm., majority 46 mm. Upperside. Ground colour dark blue- black with just a slight or no green sheen at base; fore wing base of hind wing black, inner fold dark to light ashy-grey. Fore wing discal spots usually well marked, complete in series to ib, but some variation in length of marks ; post-discal series generally larger than in Natal specimens ; white subapical spots larger ; spots in ib usually free, but if large and angled may meet discal spot in same area ; marginal spots if present, small, double in ib ; fringe white, interrupted by dark ends of veins. Hind wing discal patch white with blue suffusion on upper and outer borders, moderately wide and whiter than in nominotypical race, usually represented at subcosta by a white or bluish discal spot quite free ; on the upper and outerside by one or two post-discal bluish-white discrete spots ; distal black border with large submarginal angular blue spots with white centres, double at anal angle and brighter blue ; marginal ochreous line broken by a dark mid-line and separated by ends of dark veins ; fringe narrowly white ; tails long, upper 6-9 mm., lower 5-6 mm. seldom shorter. Underside. Ground colour slightly darker than Natal race, as a rule but pattern less strongly marked ; dark lines and ochre-olive shading less broad ; post-discal spots fore wing less marked. FEMALE. Fore wing length 47-51 mm., majority 50 mm. Upperside. Distal portions of wings black, proximal more brownish, fore wing discal bar slightly variable, but majority wider than in Natal specimens, the inner border of bar less indented and irregular due to the longer and larger marks in la-ib, the hind marginal blue streak shaded lavender-bluish and the inner portion of mark above in ib also lavender, moreover the third mark beyond the cell is also more elongated ; post-discal spots in the subapex large and white and this series usually stops in 4, but may extend to 3 but in more diffuse form, most of the spots covered with dusky scaling ; margin of wing without light spots, but fringe narrowly white. Hind wing discal patch usually large, but not so large as in nyasae or joanae, but the average larger than Natal 232 V. G. L. VAN SOMEREN specimens, the whole suffused with lavender scaling, the inner border extends to the costa where the mark is sharply defined proximad while the outer border is more dyslegnic and somewhat rayed with white scaling along the veins and one or two spots of the post-discal series may be present in 6-7 ; distal black border carries a series of triangular or elongate lavender-blue marks with white centres, double at anal angle and bluer ; marginal ochreous line usually present but strongly divided by black at mid-point and separated by ends of veins ; fringe narrowly white interrupted by dark veins ; margin slightly dentate ; tails long and slender, upper 9-10 mm., lower 7-8 mm., may be black or with narrow pale streak for entire length. In some specimens the submarginal spots are exceptionally small and obscured. Underside. Ground colour dark cold olive-grey or with a slight ochre-brown tinge ; discal white bar well marked ; post-discal spots obscured (except for two subapical) in the dark form, or more conspicuous when the ground colour is paler and the zigzag discal line in hind wing is more defined and the post-discal spots show up. Variations. A contrasting rare variation in the female is figured (PI. 23, fig. 167). Associated with this subspecies is material taken in the Newala district of southern area Tanganyika, north of the Ruvuma River. These specimens though not quite typical link up with material from Morogoro inland from Dar es Salaam on the central railway line (PI. 23, figs. 164-168). Range : This race, in typical form, ranges from the coastal belt of Kenya and Tanganyika north to the south Somali border at Milimani extending inland to Kibwezi, Voi and the Teita Hills and the Mutha district of Ukambani, to Makueni along the riverine forest patches. It also occurs in the foothills of Kilimanjaro at Moshi and Arusha and noted at Namanga. Specimens from Arusha and Manyara are less stable than typical coast material. Charaxes cithaeron nairobicus van Son (PI. 21, figs. 150-152 ; PI. 22, figs. 159, 160) Charaxes cithaeron nairobicus van Son, 1953 : 220. MALE. Fore wing length 45-48 mm., majority 47-48 mm. Upperside. Fore wing ground colour very dark purply-blue-black or deep blue-black with a greenish sheen at base in side light ; hind wing black at base with some blue-green reflections on distal border ; fore wing discal blue spots large, strongly blue or with a purply sheen, the series in a distinct curve, as spots in ib are set in basad and streak in ib is large and extends inward well beyond spot in area above ; post-discal spots all well developed, the two subapical ones white, the remainder blue, the two marks in ib approximating on inner edge and forming a cordate or arrow-head mark ; marginal ochreous or creamy spots well developed, often elongate-quadrate, separated by the dark veins ; tornus with double spot. Hind wing discal patch large, whitish towards inner fold but strongly suffused with blue on upper and outer borders, represented on subcosta by a large diffuse bluish spot and in the post-discal line by a distinct subcostal spot followed by a larger one in area below, these two spots free or occasionally suffused over with blue scales, very often these spots and those within the outer border of patch have a strong ochreous tint which shows up clearly ; submarginal spots usually large and somewhat angular, the bright double spot at anal angle often conjoined ; margin usually broadly ochreous divided by the dark veins giving the edge of the wing a dentate appearance ; fringe narrowly white ; tails robust and short, upper 4-7 mm., lower 3-5 mm. largely ochreous with only a narrow black edge. Underside. Slightly variable but ground colour usually dark olive-greyish with a tawny bloom, but it may be generally dark olive-grey in which case the white lines and ochreous spots show up conspicuously. In the paler form the hind wing pattern is largely obscured especially in the discal and post-discal areas and along the submargin, but the ochreous marginal border is broad and conspicuous. REVISIONAL NOTES ON AFRICAN CHARAXES 233 FEMALE. Fore wing length somewhat variable, denoting season and food plant ; in a dry season resultant specimens are stunted. In a very long series the wing length varies from 46-54 mm., but the large majority are 50 mm. There is a similar variation in the upperside pattern in respect to the width of the fore wing discal white bar and the development of the post-discal spots ; in the hind wing in the size of the discal patch and the sub-marginal blue spots. However, the overall characters of the Kenya highland race hold good. It is a large race and in both sexes the pattern is bold, particularly in the hind wing discal patch which not infrequently has a tinge of ochreous in the upper and outer borders corresponding to the position of the incorporated post-discal spots. The submarginal row of blue spots with white centres is usually strong and the margin is boldly ochreous. Underside. Exhibits some variation in ground colour being either dark olive-grey with bold lines and ochreous shading and the zigzag line through the disc of hind wing well developed often forming a conspicuous bar. In specimens with paler ground colour the pattern is finer and the ochreous suffusion results in suppression of a strong pattern. Some of these variations are shown on PI. 21, figs. 150-152. Range : The forests of the Kenya Highlands east of the Rift Valley, the Aberdares and Mt. Kenya, the upper Kikuyu forests and in the drier forests around Nairobi- Ngong where the species is plentiful. It also occurs in the riverine and gallery forests extending southward into Ukambani where there is some evidence that it may make contact with the subspecies kennethi.

The account of the expedition given by Mr. Andrews (1900, A Monograph of Christmas Island (Indian Ocean), London, British Museum (Natural History)) shows clearly that this is the Christmas Island that is situated south of Java, and not the island of the same name in the Pacific. Cophinopoda philippinensis sp. n. (Text-fig. 14) Ommatius fulvidus Osten-Sacken, 1882, Berl. ent. Z. 26 : in, nee Wiedemann, 1821. Osten-Sacken, in his account of Diptera from the Philippine Islands, brought home by Dr. Carl Semper, records : " Ommatius fulvidus Wied. A. Z. I. 420. Must be as common in the Philippines as in Amboina, Celebes, etc.". The single female I have seen from the Philippine Islands looks, indeed, indistinguishable from chinensis Fabricius (fulvidus Wiedemann), until we look at the genitalia, which are sharply different. Until I have more specimens for comparison I am not able to give any other points of difference, but the genitalia have proved so diagnostic in this genus that this one structure is sufficient to define the species (Text-fig. 14). Cophinopoda timorensis sp. n. (Text-fig. 12) The only known specimen is so similar in general appearance to C. chinensis that it is difficult to pinpoint any significant differences. The brown tomentum of the head and thorax is perhaps more greyish, and the tibiae have more distinct apical black rings, especially the fore tibiae. The species is really defined on the female genitalia as shown in Text-fig. 12. Holotype $. TIMOR : a single specimen collected by Alfred Russell Wallace, and given by him to W. W. Saunders. It came to the British Museum with Saunders' collection, B.M. 1868-4. DIPTERA FROM NEPAL 253 Wallace's comments in his book THE MALAY ARCHIPELAGO (1894) on the origin of the fauna of Timor are apt in comparing this species with the others of the genus. THE IDENTITY AND ORIGIN OF Ommatius androcles Walker, 1849 As already stated, this species was founded upon one specimen, a female recorded as from : " Sandwich Island. Presented by Captain Beechey ". This specimen stands in the British Museum at the present day, but unfortunately its eighth sternite is broken, and the most that can be said of it is that it appears to be indistinguishable from Cophinopoda chinensis (Fabricius). The locality attributed to this specimen is especially intriguing because no Asilidae are known from the Hawaiian Islands. Captain Beechey, who commanded the sloop H.M.S. Blossom, was despatched to the Pacific during the years 1825-28 for the purpose of waiting in the Behring Strait in case either Parry or Franklin should succeed in finding a North- West Passage. During the periods in which the Strait was frozen, Captain Beechey was ordered to cruise usefully among the islands of the Pacific, charting and surveying. He called twice at " Woahoo " (=Oahu) and actually left his naturalist there for eight months from May, 1826- January, 1827. The naturalist, Mr. Tradescant Lay, was suffering from dysentery, and Captain Beechey reasonably argued that he would be more usefully employed ashore in Hawaii than cruising in Behring's Strait. There is thus no direct reason to question the locality of the Asilid : it could have been taken in Oahu. On the other hand it could have been taken later on the voyage when the ship called at Macao. Here officers not only went ashore, but lived ashore for some time in the houses of Portuguese officials. One would think that if anyone did this the naturalist would be among them. He might easily have caught this fine Asilid there and afterwards mistakenly included it in his Hawaiian catch. I asked Prof. D. Elmo Hardy for his opinion, and he concurs in the view that Walker's type is probably a chinensis from the mainland. Prof. Hardy thinks it unlikely that such a large predatory insect would have become totally extinct in Hawaii since Beechey's time ; while I am impressed by the similarity to the eighth sternite of chinensis, and feel that if the species had really lived in such isolation on the Hawaiian Islands it would have become as distinct as andrewsi orphilippinensis.

COE SYNOPSIS The material studied comprises twenty-two genera and sixty-two species, of which eleven are described as new. Some existing species are discussed and where necessary redescribed, and keys are included to certain genera. INTRODUCTION THE bulk of the material dealt with in this paper was collected by the author while a member of the British Museum (Natural History) East Nepal Expedition 1961-62. Also included is other B.M. (N.H.) material from South-East Asia and two collections from the same region submitted for identification by Drs. F. Kuhlhorn and F. Reiser, of the Zoologisches Sammlung des Bayerischen Staates, Munich, Germany and the Naturhistorisches Museum, Basel, Switzerland respectively. As entomologist with the British Museum expedition, I was working in the field from late September to early February, a period when most of the wild plants were in seed and failed to attract Syrphidae. Moreover, cold winds and frequent frosts had by late November decimated the insect population except in sufficiently sheltered places. In the high damp evergreen oak forest above our base camp at Sangu, frost and frozen snow had by that time restricted successful collecting to barely an hour around midday when the overhead sun raised the temperature along the narrow exposed track sufficiently for the insects to take flight from their obscure hiding places. During this brief spell of activity in the high forest Syrphidae were occasionally taken throughout the winter months at altitudes up to nearly 10,000 feet. Near our base camp at around 6,200 feet a cultivated Composite (Guizotia abyssinica Cassini), from the yellow blooms of which the natives extract an oil, survived the nightly frosts of late December in a field facing south and sheltered by high evergreen shrubs from the north and east. Some interesting Syrphidae were attracted to the flowers. In early December the blooms of the same plant afforded good collecting on the Tumlingtar plateau in the Arun Valley at an altitude of about 2,000 feet. With wild blooms almost absent this cultivated plant was extremely useful for collecting Syrphidae and other insects, Hymenoptera in particular. Of the species dealt with in this paper, fifty-one were collected in East Nepal, and an analysis of their distribution reveals some facts of interest. Only nine occur in the Palaearctic Region ; twenty-seven occur in the territories extending 256 R. L. COE southward through Burma and Thailand as far as Sumatra and Java ; three occur still further south, i.e., in Northern Australia ; and three occur in the Ethiopian Region. However, of the twenty-two genera taken in East Nepal, twenty occur in the Palaearctic Region ; one (Megaspis) occurs in the Ethiopian Region ; and one (Lycastris) is peculiar to the Oriental Region. In the following text, collectors' names are given when the material was taken other than by the author. Subfamily SYRPHINAE Paragus tibialis tibialis (Fallen) Pipiza tibialis Fallen, 1817 : 60.

The following Paragus species all belong to the sharply differentiated group with very deeply serrated scutellum, bearing a marginal row of conspicuous teeth, as denned by Stuckenberg (1954 : 409).

Through the kindness of Dr. Kjellander, of Stockholm, I was enabled to compare my single example of the typical form of this species with the sole existing specimen in Thomson's collection at the Naturhistoriska Riksmuseum. They agree in all respects, thus confirming Stuckenberg's interpretation of Thomson's description.

This material agrees with Stuckenberg's description of three specimens from Calcutta, in which the body is dark, the mesonotal pile white, and the mesonotal stripes complete and silvery. Also, the thorax is more coarsely punctate than in the typical form, and has dull violaceous and a few cupreous reflections. As Stuckenberg remarks there is considerable variation within the species, which could probably be divided into several subspecies if more material became available.

Frequent in EUROPE and INDIA. My Nepalese material agrees with the series of European torvus in the Brit. Mus. (Nat. Hist.), except that in both sexes the dust on frons is golden instead of grey. However, a single $ from Sweden agrees with my series in this respect. Osten-Sacken described his torvus from North America, but I have seen no material from that sub-continent that agrees with the species as now understood, and it is possible that there are two species confused here. Syrphus pellucidipennis sp. n. (Text-figs. 1-2) FEMALE. Length (exclusive of antennae), 15-5 mm.; wing-length, 14-5 mm. Eyes rather narrowly separated at vertex, the space between them steadily increasing from shortly above front ocellus to their lowest extremity ; eye-hairs dense, yellowish, rather short above, longer below. Vertex shining blackish olive, scarcely dusted, with short black hairs. Frons shining olive, with dense wide golden dusting at sides ; lunula shining blackish olive. Face (Text-fig. 2) broad, broader than the maximum width of an eye, very shortly descending below eye-level, moderately hollowed beneath antennae and with moderately produced central prominence ; yellow, with rather sparse pale golden dusting except on the shining, more orange, central prominence. Antennae greyish black, the first segment slightly shining, second and third dull ; first and second subequal in length, third about as long as first two together, rather narrow, tapering towards tip. Arista rather short, reddish, slightly darkened towards tip. Thorax greyish green, scarcely shining, becoming orange at sides, clothed with mainly rather short yellow hairs on disc and with longer light orange hairs at sides ; scutellum yellowish orange, slightly shining, with rather long fine intermixed yellow and black hairs. Pleurae mainly greyish green, extensively dulled by dense pale golden dusting and with moderately dense rather long light orange hairs. Abdomen with first tergite and extreme base of second moderately shining grey ; remainder of second tergite black, dull towards base, shining towards tip, with a pair of narrow, widely divided yellow fasciae halfway along tergite, these not extending over side-margins ; third tergite black, similarly dull towards base, shining towards tip, with a tiny isolated reddish yellow spot at middle towards base and a slight trace of reddish at middle of hind-margin ; fourth tergite black, similarly dull towards base, shining towards tip, with a much more extensive reddish marking spreading across hind-margin and extending forward for a short distance at median line, thus appearing narrowly triangular ; fifth tergite with an almost equilaterally triangular reddish marking extending forward from hind-margin. Sternites mainly blackish. Four anterior femora narrowly blackish at base, hind pair with more than basal half blackish, all tibiae yellowish, four anterior tarsi yellowish, hind pair darkened dorsally. Leg-hairs mainly following ground colour on the two anterior pairs, but on the hind pair the short black femoral hairs are continued over the yellow apical half, and the tibiae have numerous short black hairs for their entire length, these becoming conspicuous and close-set along the apical half. Squamae yellowish, fringed with long golden hairs. Halteres yellowish. Wings pellucid apart from the light yellowish brown stigma. 260 R. L. COE Holotype $.

Apart from the very restricted yellow markings on the abdominal tergites, its dull green thorax and hairy eyes would lead one at first glance to consider it a close ally of torvus Osten-Sacken (q.v.) of the ribesii- vitripennis group of the genus. However, the lower lobe of the squama is devoid on the disc of the numerous long yellow hairs characterizing that group, microscopic pile only being present. Curran (1928 : 201) described a Syrphus chrysotoxoides from a single $ taken in Siam, and this example shares with my new species the combination of characters mentioned above. Curran's type specimen of chrysotoxoides is in the Brit. Mus. (Nat. Hist.), and is gummed to a card and in very poor condition. From certain omissions of detail in Curran's description it seems probable that he described it in its present state. Although sharing the characters detailed, chrysotoxoides differs from my new species in many respects. The face (Text-fig, i) of chrysotoxoides is considerably narrower, at its maximum width being less than the maximum width of an eye ; antennae extensively reddish ; wings evenly smoky yellow ; all tergites extensively yellow ; sternites mainly yellowish ; and all femora entirely clear reddish orange. Syrphus brunettii Herve-Bazin Syrphus brunettii Herve-Bazin (pro albostriatus Brunetti nee Fallen), 1923 : 290. Syrphus albostriatus Brunetti nee Fallen, 1923 : 72. EAST NEPAL : Sangu, c. 6,200 ft., from mixed vegetation in deep gully, 11.1962, 2 (£ ; from damp evergreen oak forest above Sangu, c. 8,500 ft., 2-26.xi.i96i, i $. The above material that I took in East Nepal and one $ and two $ in the Brit. Mus. (Nat. Hist.) from North East India agree with Brunetti's description of his supposed albostriatus Fallen, as amended to brunettii by Herve"-Bazin, except that Brunetti states that the eyes in the male are " absolutely contiguous for only a short distance ". Actually, both albostriatus and the material that I now identify as brunettii have the eyes touching for a considerable distance in the male. Unfor- tunately I have been unable to check the type series of brunettii at the Zoological Survey in Calcutta, but I am satisfied that Brunetti's statement is a lapsus calami. Further, had Brunetti's examples of the male truly had the eyes touching for only a short distance, Herv6-Bazin would surely have drawn attention to this further distinction from the true albostriatus when renaming the series. Syrphus serarius Wiedemann Syrphus serarius Wiedemann, 1830 : 128. EAST NEPAL : Taplejung District, Sangu, c. 6,200 ft., from mixed vegetation by stream in gully, x. 196 1-1.1962, i <$, 5 $.

EAST NEPAL : Taplejung District, Sangu, c. 6,200 ft., from blooms of Guizotia abyssinica Cassini, io-i6.xii.ig6i, i <$. This single male example of a Syrphus of the luniger group agrees with the uncommon nitens in having the third and fourth tergites with the yellow bands not, or scarcely, broader than the black cross-band separating them, and than the black cross-band bounding the front margin of the third tergite and the hind margin of the second tergite. The yellow bands of the third and fourth tergites are, however, narrowly divided into lunules instead of being entire and the central prominence of the face is rather broadly darkened. Otherwise it agrees quite closely with typical male nitens. Occurs widely in EUROPE (typical form). Syrphus bait eat us (Degeer) Musca balteata Degeer, 1776 : 116.

I have examined the male holotype of circularis Curran, 1930, and find that it is identical with multifarius Walker and therefore becomes a synonym of the latter species. Hull (1949 : 397) gave circularis Curran as a synonym of Helophilus singularis Walker (1856 : 17), originally described as an Eristalis. Hull is incorrect here, as singularis is a true Helophilini with its widely open marginal cell. Hull's Merodonoides minutus (1944 : 43) (syn. n.) of which the male holotype is in the Brit. Mus. (Nat. Hist.) is only a pale variety of multifarius. Megaspis zonata (Fabricius) Syrphus zonatus Fabricius, 1787 : 337. Megaspis zonatus (zonalis) (Fabricius) de Meijere, 1908 : 240.

The latter is in the Brit. Mus. (Nat. Hist.), together with a series of 5 <$ and 3 $ collected in the Naini Hills, NORTH INDIA (R. C. Jermyn). Brunetti's type $ has the face almost entirely orange-yellow, but two of Jermyn's females have it entirely black, while his remaining one has the upper part black and the lower part orange-yellow. In the apparently undescribed male, the ground colour of the face from the front view is completely hidden by dense whitish dusting, but by tilting the specimen 278 R. L. COE backwards and viewing the face from beneath the latter is seen to be yellow on more than the lower two-thirds. The male differs principally from the female in the following respects : — Eyes touching briefly for a distance about equal to length of the vertical triangle ; frons, including frontal prominence but excluding the orange-yellow lunule, heavily white-dusted ; abdomen narrower, hour-glass shaped, i.e., second tergite narrowing to tip, third tergite narrowing to base.

In Naturhistorisches Museum, Basel, Switzerland. This handsome species appears to be related to pallipilosa Hull (1944 : 34), described originally from a series of four males. Later Hull (1950 : 610) described the female of pallipilosa from a single specimen. All the material described is in the Brit. Mus. Nat. Hist.) and bears the following data, " Kashmir : Gulmarg, 8,500 ft., summer 1913 (Lt.-Col. F. W. Thomson) ". A striking sexual dimorphism in pallipilosa is that in the male the entire frons and the face apart from the sides is densely covered with pale brownish yellow extremely minute pubescence, whereas in the female the frons is partially shining black and the face is shining blackish brown or brown apart from a narrow band of greyish or pale yellowish dusting immediately under the base of the antennae. Described from the female only is the subspecies bicolorata Hull (1950 : 610) of pallipilosa (which differs from the typical examples in the colour of the abdominal pile) and a third related species, rubropilosa Hull (1950 : 608). These females all have the face shining black, blackish brown or brown, without dusting apart from the narrow band of greyish or pale yellowish dusting immediately under the base of the antennae. The striking and clearly differentiated sequence of black, yellow and orange in the coloration of the body-pile of tripilosa contrasts most obviously with the pre- dominantly grey body-pile of pallipilosa and its subspecies bicolorata and of rubropilosa, apart from the considerably more thickened hind femora of tripilosa with their very dense long black hairs. (Note: — While it was hoped to include a specific key to the numerous species of Oriental Criorhina in the present paper, this has proved impracticable because less than half the described species are in the Brit. Mus. (Nat. Hist.), and of the others some cannot be made available for study, and many descriptions omit to mention characters that would be of vital importance in a key.) Lycastris austeni Brunetti Lycastris austeni Brunetti, 1923 : 279. Brunetti described this handsome species from a male and female taken in NORTH EAST INDIA, Darjeeling, 6,000 ft., 26.^.1894, $ ; 7,000 ft., v.i894, $ (C. T. Bingham). Both examples are in the Brit. Mus. (Nat. Hist.). DIPTERA FROM NEPAL 281 The long shaggy body pubescence resembles that of Volucella bombylans Linnaeus, the yellowish hairs on the basal tergites being succeeded in turn by black and then reddish hairs. This species and griseipennis sp. n., described below, are much larger than the three other species known in the genus. The length (exclusive of snout and antennae) of austeni is 17 mm., and the wing-length 16 mm. Lycastris griseipennis sp. n. MALE. Length (exclusive of snout and antennae), 16 mm. ; wing-length, 15 mm. Superficially resembling austeni, but most obviously distinguished by the almost uniformly greyish wings with only slight clouding on cross-veins. Eyes in contact for not more than the distance between their posterior point of approximation and the anterior ocellus. Snout projecting for about three times the length of frons, but this may be variable as in some other species of the genus. Both snout and frons are dark brown to blackish, shining, base and sides of the frons with some pale yellow dusting, and a continuous line of similar dusting extending narrowly along the extreme lateral margin of the frons and continuing broadly along the sides of the snout for practically its entire length. Antennae and arista brownish. Thorax blackish brown, only slightly shining, with rather long dark reddish brown hairs, these more blackish towards the sides and on the reddish brown humeri. Scutellum with dark greenish ground colour, clothed with long shaggy yellowish hairs. Abdominal tergites with similar ground-colour, second tergite with long shaggy sub-depressed yellowish hairs obscuring ground-colour and extending over basal part of third tergite. The hairs on apical part of latter and on fourth tergite and pre-genital segment are foxy red (in $ paratype these become dark grey on pre-genital segment). Legs with coxae and trochanters black or dark brown ; front and mid femora brownish red for about basal half, then pale yellow, fringed mainly with long brownish hairs, these being replaced by pale yellow hairs shortly after middle ; hind femora moderately thickened, brownish red, broadly yellow- tipped, the long brownish fringe extending almost to tip, then replaced by pale yellow hairs ; front tibiae pale yellowish, vaguely darkened at extreme tip, mid pair entirely pale yellowish, both pairs fringed for entire length with long pale yellow hairs ; hind pair pale yellowish for almost basal half, then brownish red, the long pale yellow fringe of hairs on basal half admixed with brownish hairs on apical portion ; front and hind tarsi entirely brownish black, with very short brown and black hairs ; mid metatarsi pale yellow with extreme tip darkened, fringed mainly postero-ventrally with long pale yellowish hairs for about basal three-quarters, then with shorter dark brown hairs, which continue along remaining four tarsal segments, which are blackish. Wings evenly greyish, with clouding on cross-veins. Squamae greyish with fringe of rather long yellow hairs. Halteres pale-stalked with brown or black knob. Holotype $.

W. Saunders collection, its sole data being " India ". Brunetti (1908 : 85) described as new Lycastris 282 R. L. COE flavohirta from two males taken by him at Darjeeling on 10-15. ix. 1905 (Type) and on 25.ix.iQo6 (Paratype). Later (1923 : 279) he sank flavohirta as a synonym of albipes. His action in thus combining two such well denned species can be understood because he had at that time only Walker's teneral female type of albipes to compare with flavohirta. Identical with albipes is Lycastris (Xyphopheromyia) glossata Bigot (1892 : 161), which is represented in the Brit. Mus. (Nat. Hist.) by the two male co-types from Sabatoo, INDIA. I describe below for the first time the true male of albipes, and necessarily redescribe the female, which Walker, as already stated, described from a teneral female. MALE. Length (exclusive of snout and antennae), ii'5-i4'5 mm. ; wing-length, 11-14 mni. Eyes in contact for not more than the distance between their posterior point of approximation and the anterior ocellus. Snout projecting for about three to three and a half times the length of frons. Both are dark brown to blackish, shining, base and sides of the frons with pale yellow dusting, which has a tendency to spread across middle towards base and continues broadly along the sides of the snout for more than its basal half. Vertex with long yellow hairs, these becoming longer behind. Antennae and arista pale brownish. Mesonotum with shining greenish black ground colour, obscured by yellowish grey dusting and with a pair of closely applied dull greenish grey median longitudinal stripes clearly visible at least anteriorly ; clothed with rather abundant yellowish hairs, these moderately long on disc, longer towards sides and posteriorly.

Pre-genital segment shining brownish black with rather sparse and long brownish black hairs. Legs with coxae and trochanters greenish black, more or less distinctly grey dusted ; front femora moderately thickened, ventrally with a rather triangular short blackish projection shortly before middle ; hind femora considerably swollen, obviously convex above ; front and mid pairs black for more than basal half, then yellow, hind pair almost all black, narrowly yellow only at extreme tip ; all femora with rather long, mainly yellowish white hairs. Front and mid tibiae pale lemon-yellow with fringe of whitish yellow hairs, these much longer on mid pair ; hind tibiae black for at least basal three-quarters, remainder reddish yellow, the whitish yellow hairs of varying lengths and variously directed. Front metatarsi clear yellow, more or less extensively brownish towards tip, remaining four segments brownish black ; mid tarsi mainly clear yellow, only two apical segments darkened ; hind tarsi entirely brownish black ; hairs on all tarsi mainly short, whitish yellow, only mid pair with rather longer similar hairs ventrally and posteriorly.

My recent capture in East Nepal of a single female of Lycastris led me to study the genus, with the result that I find flavohirta to be an undoubtedly distinct species, of which my Nepalese specimen is the hitherto undescribed female. A redescription of the male and description of the female follows. MALE. Length (exclusive of snout and antennae), 11-12 mm. ; wing-length, 10-11 mm. Eyes in approximation for not more than distance between hind ocelli and front ocellus.

Lycastris cornutus Enderlain Lycastris cornutus Enderlein, 1911 : 136 ($). Lycastris cornutus Enderlein (Sack), 1913 : 7 (<$). Enderlein described cornutus from a single female taken at Kosempo in SOUTH FORMOSA on 23.1.1908 (H. Sauter}, and now in the Stettin Zoological Museum. In 1913 Sack described the male from a series of both sexes taken at Hoozan and Taihorinsho in FORMOSA by the same collector on an unspecified date. Brunetti (1923 : 279) queried the validity of cornutus as a result of examining a female in the Brit. Mus. (Nat. Hist.). This specimen bears the data : — " Formosa, Chip Chip, og.ii, Sauter, presented by Dr. K. Kertesz, Budapest Museum ". I have examined the specimen concerned and also a male from the same source, and find that they agree respectively with Enderlein's description of the female and Sack's subsequent description of the male of cornutus. The latter is certainly a good species, closely related toflavohirta Brunetti, from which my key characters clearly distinguish it. So far as is known the genus Lycastris occurs only in the Oriental Region. The five species that I recognize in the present paper are keyed below. 1 At least second tergite with ground colour hidden by long shaggy sub-depressed yellowish hairs ............ 2 - Ground colour clearly visible on all tergites, the mainly or entirely pale hairs shorter, scantier and at most sub-depressed on posterior margins ..... 3 2 Wings intensely infuscated along at least anterior half, fading off towards tip and posteriorly ........... austcni Brunetti - Wings evenly greyish, with slight clouding on cross-veins . . griseipennis sp. n. 3 Tergites 2-4 shining black, any pale markings restricted to extreme base and tip of tergites, and occasionally a small yellowish somewhat triangular area at basal corners of third tergite. Male front femora thickened, ventrally with a short blackish projection shortly before middle ; hind femora considerably swollen, convex above, pale at extreme tip, otherwise black. Female hind femora similarly coloured .......... albipes Walker - Tergites 2-4 otherwise coloured, brownish or greenish or a mixture of both.

Verrall described this rather inconspicuous species from a single male example taken by Lieut. E. Y. Watson in the North Chin Hills in BURMA, 5,000 ft., iii.i893. Its almost entirely reddish orange legs distinguish it from other Oriental species with the first antennal segment scarcely or not longer than the second. As Verrall mentions in his original description, the abdomen of the type is much spoilt by damp, and it is difficult to make out the colouring of the tergites. This apparently unique example of the species is in the Brit. Mus. (Nat. Hist.). Callicera sumatrensis de Meijere (Text-fig. 12) Callicera sumatrensis de Meijere, 1919 : 26 ($). Callicera pendleburyi Curran, 1928 : 273. Syn. n. De Meijere described this species from a single female taken at Suban Ajam in SUMATRA by Herrn. Edw. Jacobson in July, 1916. From the original description it appeared to me to be closely related to pendleburyi Curran, and at first I separated the two species in my key by the rather unsatisfactory character of the entire antennae being black in sumatrensis (as stated by de Meijere) and the first segment reddish in pendleburyi. Later, de Meijere's type female of sumatrensis was kindly lent to me by Dr. Willem N. Ellis from the collection in the Zoological Museum of the University of Amsterdam. Examination proved that the first antennal segment in this specimen is obviously reddish and not black as stated by de Meijere. Indeed, sumatrensis and pendleburyi are identical, and the latter becomes a synonym of the former. Curran fully and accurately described pendleburyi from five males taken at Cameron's Highlands, Pahang, MALAYA, the full data of the material being as follows : — Rhododendron Hill, 5,200 ft., 20. vi. 1923, i $ ; Gunong Berumban (summit), 6,050 ft., I4.iii. and 17^.1923, 3 £ ; same locality, 5,100 ft., I2.iii.i925, i <$ (H. M. Pendlebury). In subsequent years Pendlebury collected many further examples (with one exception, males) from the same localities as before, and a single male from NORTH BORNEO. His material forms the entire series of forty-two specimens in the Brit. Mus. (Nat. Hist.). Curran was apparently unaware that a female existed in the B.M. material and did not describe that sex. As de Meijere's description of the type female of sumatrensis was taken from a somewhat teneral and rubbed specimen and is not entirely accurate (as shown earlier) I give below the main features in which that sex differs from the male, 286 R. L. COE using for comparison the single female that I have found in the B.M. series of pendleburyi : — Antennae (Text-fig. 12) with segments proportionately longer ; eyes widely separated, the space between them steadily widening from shortly below front ocellus to their lowest extremity, at least twice as widely separated at level of antennae as at level of front ocellus ; eye-hairs shorter and all pale ; thorax much more shining aeneous, less greenish black ; tergites with shorter hairs ; legs almost entirely pale haired. The data of the female examined is as follows : — " Cameron's Highlands, Pahang, 4,800 ft., 7.vi.i935 ". It should be noted that in his description Curran gives the length of pendleburyi as 12-12-5 mm. This may be taken as an average body measurement, but among the long series of males subsequently taken by Pendlebury the range is from 10-13 mm. De Meijere gives the length of the holotype female of his sumatrensis as 9 mm., but actually it measures 10 mm. Callicera robusta sp. n. (Text-fig, n) This species is distinguished from other Oriental Callicera with the first antennal segment at least twice as long as second by, among other characters, the almost entirely clear reddish orange legs. It is also larger than the rest. MALE. Length (exclusive of antennae), 15 mm.; wing-length, 13-5 mm. Eyes actually touching for a distance about equal to twice the length of vertex, clothed with rather short pale yellow hairs, which become light brown on the upper part, and with a vertical central band of dark brown hairs. Frons shining bluish black, with a narrow yellowish orange lunule at base of antennae, bare.

Watson at Fort White in the North Chin Hills, BURMA, 7,000 ft., iv.iSga. This sole repre- sentative of the species is in the Brit. Mus. (Nat. Hist.). Unfortunately, for many years this specimen has been a mere fragment, headless, legless, and almost wingless, and is quite unrecognizable. On examining a series of one male and six females placed with it over the name label of sackeni and comparing their characters with Verrall's description of the latter I found that they represent a distinct species, which I have described earlier in this paper as robusta. I will not repeat Verrall's excellent description of sackeni, which has already been transcribed word for word by Brunetti (1923 : 306). It is clearly differentiated in the following key to the six Oriental species of Callicera that I now recognize.

Seven specific synonyms are newly established and three new species are described. INTRODUCTION TYLOPSIS Fieber is one of the most easily recognized genera of Phaneropterinac. Its species present more difficulty, however, and the description of a number of new African species during the past twenty years has made the identification of the Ethiopian members of the genus even more difficult. It is hoped that this revision, the first since Brunner's Monograph of 1878, will remedy this situation. The genus was first given the name Centrophorus by Fischer de Waldheim in 1846 ; he based the name on some immature specimens, which he named C. spinosus. This generic name subsequently proved to be a homonym of a genus of fish described by Miiller & Henle in 1837, and the specific name was a synonym of Locusta lilifolia Fabricius, 1793. The genus Tylopsis was erected by Fieber in 1853 for the single species Locusta lilifolia Fabricius. This generic name later became involved in a controversy concerning the type-species of Phaneroptera Serville, 1831 (see Ragge, 1956 : 206), of which one of the two originally included species was misidentified as L. lilifolia Fabricius. In 1944, however, Tylopsis Fieber was added to the Official List of Generic Names in Zoology, with L. lilifolia Fabricius as its type-species (Hemming, 1944)- Kirby, in his Catalogue of 1906, listed ten species of Tylopsis Fieber. Ten species are also recognized in the present revision, though five of these names are new to those listed by Kirby. Two of the names in Kirby's list, " T. plana (Walker) " and "T. turbata (Walker) " do not belong to Tylopsis Fieber (see below), and three further names have been found to be junior synonyms. 298 D. R. RAGGE The species listed in Kirby's Catalogue as " T. plana (Walker) ", based on a male holotype, may be placed for the time being in the genus Symmetropleura Brunner, 1878. This genus is based on a Neotropical type-species, S. laevicauda Brunner, 1878, and contains two further Neotropical species and two African species. It is quite possible that these African species will eventually be given separate generic status and that the present species, which is not closely related to them, will be considered to represent a third distinct genus, but it would not be appropriate to settle these questions here. The species listed by Kirby as " T. turbata (Walker) ", which is known only from the male holotype, belongs to the genus Phlaurocentrum Karsch, 1888. The holotype is unfortunately in very bad condition, and it is impossible to draw any conclusions regarding its affinity with the other species of Phlaurocentrum Karsch ; the genitalia, which are of prime diagnostic importance, are not mentioned in the original descrip- tion. The name is thus a nomen dubium, though it seems likely that it is synonymous with one of the nominal species of Phlaurocentrum Karsch at present recognized (see Ragge, 1962). The nomenclatural adjustments that follow from the above considerations are set out below. Symmetropleura plana (Walker, 1869) comb. n. Phaneroptera plana Walker, 1869 : 339.

Access was gained to all the type-specimens that have not been lost or destroyed except for those of T. dubia Giglio-Tos, 1907 (in the Istituto e Museo di Zoologia della Universita, Turin) and T. coi Jannone, 1936 (in the Istituto e Laboratorio di Entomologia Agraria, Portici). T. dubia Giglio-Tos, which is based on three syn- types from East Africa, cannot unfortunately be identified from the original descrip- tion, though it is almost certainly one of the species recognized in this revision ; I have therefore been forced to omit it. T. coi Jannone is discussed on p. 305. For most of the species the material examined was rather extensive ; where the data of this material are listed I have therefore abbreviated it for all the previously described species except T. dispar Sjostedt and T. gracilis Chopard, by omitting the collectors' names, restricting the datal information to the month (represented by a Roman numeral), and abbreviating names of provinces, where repeated, to their initial letters. The data of type-material are, however, given in full for every species. Throughout this paper " Congo Republic " refers to the former Belgian colony. The author's usual conventions are observed (see Ragge, 1957 : 124).

Abdominal tergites usually with median carina ; posterior margins often produced into point. DISCUSSION. Tylopsis Fieber is a remarkably well-defined genus, with no close relatives among other Phaneropterinae ; in his Monograph of 1878 Brunner placed it in a group of its own, and it has acquired no synonyms since it was first established. Its facies is Phaneroptera-like (though usually more attenuate), but it is clearly separated from Phaneroptera Serville and allied genera by its slit-like tympanic apertures. The male genitalia of Tylopsis Fieber are unusually uniform, all the known species having a subgenital plate of the same form and showing few striking differences in the structure of the cerci. The genus is in fact unusual among Tettigoniidae in that it is necessary to have specimens of both sexes in order to be certain of the identity of some of the species. Although most of the species have a very similar ovipositor, the female subgenital plate shows marked differences in shape, clearly characterizing a number of the species. In some species, however, this structure shows considerable geographical variation : this is especially true of T. lilifolia (Fabricius) (see p. 305) and T. irregularis Karsch (see p. 307). Among non-sexual characters the shape of the lateral pronotal lobes provides a useful character for separating the species, but is also sometimes subject to geographical variation. DISTRIBUTION. Tylopsis Fieber occurs throughout the Ethiopian Region and extends northwards through the Mediterranean Region into the southernmost parts of European Russia. KEY TO THE SPECIES As mentioned above it is desirable to have specimens of both sexes when identifying species of Tylopsis Fieber : in some species the males are more easily recognizable, in others the females, and in some a certain identification is difficult if either sex is not available. In comparing the male cerci with Text-figs. 1-13 it is essential to view them from above and at right-angles to the principal plane of curvature. In determining the relative lengths of the fore wings and hind femora it is necessary to measure both these structures, and not to draw conclusions from the relative positions of the hind knees and the tips of the flexed fore wings. 1 Pronotal disc dark brown or red-brown, contrasting with the paler lateral pronotal lobes .............. 2 — Pronotal disc similar in colour to the lateral pronotal lobes, or with the dark colouring restricted to a narrow median band ........ 4 2 Fore wings less than 20 mm. in length.

This is the only species of the genus in southern Europe and the Levant. In parts of North Africa and Arabia, however, it overlaps in range with T. irregularis Karsch ; it may be readily distinguished from that species by the shape of the lateral pronotal lobes, which lack a produced posteroventral angle. The material I have examined from Algeria, Libya, southern Jordan and the Arabian Peninsula differs in several respects from material from the remaining parts of the range. The insects are usually smaller, the male cerci are more attenuate at the tip (Text-fig. 2), and the lateral lobes normally characteristic of the female subgenital plate are completely lacking (Text-fig. 35) ; also, the lateral pronotal lobes tend to be more angular (Text-fig. 19). When further material becomes available it will doubtless be advisable to regard this form as a distinct subspecies ; it may even prove to be specifically distinct from T. lilifolia (Fabricius). The material at present available is, however, quite inadequate for a definite conclusion to be drawn, and for the time being it is better to regard the specimens from these southerly parts of the range as belonging to a deserticolous form of T. lilifolia (Fabricius) . The type-material of T. coi Jannone was unfortunately not available for study, 306 D. R. RAGGE but it seems very probable from the well illustrated original description that this name is a synonym of T. lilifolia (Fabricius). This cannot be established with certainty, however, in the absence of the holotype. MATERIAL EXAMINED.

The shape of the lateral pronotal lobes and the strongly undulate tips of the male cerci enable this species to be quite easily distinguished from the other members of the genus. It is by far the most common and widespread species of Tylopsis Fieber in West Africa, and seems in fact to be the only species in much of this region. All the females examined from west of the Adamawa Highlands had subgenital plates with well-developed lateral lobes (Text-figs. 36 and 37). In the East African material, however, these lobes were almost always lacking or at the most very poorly developed ; the Congolese material showed a mixture of the two types, and this was also true of the Arabian females. The characteristic shape of the lateral pronotal lobes and of the male cerci is fairly constant throughout the range. It is impossible to be certain from the material at present available whether this difference in the shape of the female subgenital plate (which parallels the similar difference shown by T. lilifolia (Fabricius) (see p. 305)) is due to geographical varia- tion or polymorphism. The overlap in range of the two types that seems to occur in the Congo Republic, in Uganda (a female from " Karamoja " is of the West African type) and in Arabia suggests polymorphism, with a pronounced tendency towards allopatry by the two polymorphs, but this question cannot be settled definitely until more material is available. Examination of the type-specimens of T. perpulchra Burr, T. obscuripes Chopard, T. villiersi Chopard and T. lamottei Chopard has shown that they are conspecific with the type-material of T. irregularis Karsch.

The shape of the male cerci of this species is approached only by that of the deserticolous form of T. lilifolia (Fabricius) (p. 305), which, however, does not occur in Africa south of the Sahara. The subgenital plate of the female could be confused only with that of T. irregularis Karsch, from which T. bilineolata (Serville) may be distinguished in Tanganyika, where the ranges of the two species probably overlap, by the shape of the lateral pronotal lobes. The large amount of Madagascan material that was available for this study has been rather difficult to assess taxonomically. It falls into two fairly distinct groups : a large form (total length about 40-45 mm.) and a small form (total length about 30 mm.) ; a few specimens are intermediate in size. Apart from the size difference these two forms resemble each other closely ; the male cerci and female subgenital plate are very similar, and it is only the pronotum that shows an appreciable difference (see Text-figs. 26 and 27). Taken together and compared with the species of Tylopsis Fieber that occur on the adjacent part of the African mainland, the two forms agree very well with T. bilineolata (Serville) in the shape of the male cerci and female subgenital plate (and, in the case of the large form, in size), though the pronotum of both large and small forms shows some difference (see Text-figs. 24-27). I have therefore chosen to regard the Madagascan material as consisting of slightly modified forms of the present species ; the large and small forms may have resulted from two immigrations by the African population of T. bilineolata (Serville) at widely separated times.

The lateral pronotal lobes vary a little in shape. There is variation in the number of tibial spines and spurs, especially the dorsal spines of the hind tibiae. The relative length of the fore wings varies appreciably, some of the Congolese specimens having noticeably shorter wings than usual ; there is similar variation in the relative length of the legs and, in the female, of the ovipositor. REVISION OF THE GENUS TYLOPSIS 313 DISCUSSION. The nature of the female subgenital plate, with its deep median split, is unique in the genus. The male is less easily recognized, but may be distinguished from the males of the other East African species by the shape of the cerci and lateral pronotal lobes, taken in combination ; the small blackish spot on the stridulatory rib of the left fore wing is also quite characteristic, though this feature is often also shown by the Madagascan form of T. bilineolata (Serville). T. fissa sp. n. seems to be the most common species of the genus in Uganda, Ruanda, Urundi, and the extreme east of the Congo Republic, though T. irregularis Karsh occurs more sparsely in all these areas.

The almost invariable dark brown or red-brown colour of the pronotal disc (occasionally restricted to a narrow median stripe and rarely absent) enables this species to be readily distinguished from all the other species of the genus except T. rubrescens Kirby and T. gracilis Chopard ; when this dark colouring is not developed the male may be recognized by the shape of the cerci, and the female by the shape of the subgenital plate and the basal plates of the ovipositor. T. continua (Walker) may be easily distinguished from T. gracilis Chopard by its much larger size, and from T. rubrescens Kirby by the male cerci, which are not or hardly bent upwards near the apex, and the basal plates of the ovipositor, which lack a postero- ventral lobe ; the three species also differ in the shape of the lateral pronotal lobes (cf. Text-figs. 31-33). The ovipositor of this species shows considerable variation in size : it is usually relatively larger than in the other species of Tyhpsis Fieber and in some of the South African specimens examined it was extremely large (see Text-figs. 50-52). This may be an indication that sibling species are involved, but this question cannot be settled until more material is available. Three of the Southern Rhodesian males examined, and one male and two females 50 51 52 FIGS. 50-52.
