I Hymenoptera Orientalis ; or Contributions to a know- ledge of the Hymenoptera of the Oriental Zoological Region. By P. Cameron. Communicated by John Boyd, Esq. {Received March iit/i, iS8g.) Part I. Introduction. Notwithstanding the large number of our countrymen who reside in our East Indian possessions, our knowledge of their insect fauna, ev^en of the Hindostan peninsula, is exceedingly meagre and fragmentary. A good beginning has been made towards the study of the Lepidoptera, but the same can hardly be said of the other orders. As regards the Hymenoptera, excellent work has been done by our distinguished countryman, Mr. A. R. Wallace, more par- ticularly in the Islands ; and his labours have been recorded in numerous papers by my late friend, Mr. Frederick Smith, of the British Museum. But, with all that, very much remains to be done before our knowledge of the Oriental Hymenoptera can be fairly stated to be at all adequate. The fact that less than 2,000 species have been recorded from the Oriental region is sufficient evidence of the truth of this statement ; and of the need of the attention of Indian residents being directed to such a promising field of entomological study. My own attention was drawn to the inquiry by Mr. G. A. James Rothney offering to place at my disposal for study the beautiful and extensive collection formed by him during many years' residence in India, chiefly in the Calcutta district. This valuable source of information has been 2 Mr. Cameron 07i supplemented by Mr. E. C. Cotes, lending me the material in the Calcutta Museum ; by a large collection belonging to the Bombay Natural Society, formed by Mr. R. C. Wroughton, District Forest Officer at Poona ; and by various small collections, including a small, but very interesting one, made by Mr. George Lewis, in Ceylon. In order to make this paper as useful as possible, more particularly to Indian residents, I have given : — (i) A catalogue of all the known species, with their localities, synonyms, habits, &c. (2) Descriptions of rare or imperfectly known species. (3) Descriptions of the new species. (4) A list of all the works and papers relating to the Oriental Hymenoptera, and (5) Observations on their geographical relations. Mr. Rothney's collecting was chiefly in the Calcutta district, namely, in the neighbourhood of the City ; in Barrackpore, Sittaghui, Samnugga, Ishapue, Serampue, Chandauague, Gusery ; at Port Cauumy to the south, Burdwan to the north ; Nischindepue to the north-east. Also in Tirhoot, Bengal ; Mussourie, North-west Province (in September and October), in Allahabad, North-west Province ; and a few species from Dargeeling, Madras, Bombay, and Ceylon. Mr. Wroughton's collecting is principally from Poona (Dekhan) and Bombay. SPHEGID/E. Ammophila. Ainniophila, Kirby, Trans. Linn. Soc. IV., p. 195. PsammopJiila, Dahlbom, Hym. Ent. I., p. 16.

Antennx short, thick ; the second joint two-and-a-half times the length of the fourth. Head broad, retreating Hymenoptera Orientalis. 5 behind the eyes, which are large and almost parallel ; ■covered with a short sparse white down, and sparsely with longish black hairs ; front and vertex obliquely aciculated, the former only excavated immediately above the antenna; and without a longitudinal furrow ; clypeus sparsely punc- tured ; its apex almost transverse in the middle, the sides somewhat oblique ; the centre slightly incised ; mandibles obscure reddish towards the centre, the outer side broadly at the base striolated. Thorax covered with a fuscous pubescence ; the tubercles and a spot on either side of the median segment silvery. Pro- and mesonotum strongly transversely striolated, the striolations rather widely sepa- rated ; propleuras obliquely striolated ; meso- and meta- pleurae longitudinally rugosely punctured ; metanotum transversely rugosely punctured ; scutellum longitudinally striolated ; mesonotum with a shallow channel in the centre ; metanotum not elevated in the centre ; a shallow indistinct furrow below the spiracles. Petiole longish ; the second joint usually blackish at the base. Coxs covered with a dense moderately long silvery pile ; the trochanters, tibije and tarsi, with a shorter and thinner one ; hind coxa; coarsely punctured ; tarsal spines black ; fore calcaria red ; hinder black, reddish at base ; apex of tarsi black. Second cubital cellule at top a little wider or a little narrower than the space bounded by the recurrent nervures ; third cubital cellule a little wider at top than at bottom, the second transverse cubital nervure bent outwardly at the bottom ; tegulae blackish to piceous. A. Jmmbertiana, Saus. from Java, seems to be the nearest ally of this species, but it has the metanotum " postice oblique in V-formam elevato-strigato," and the trochanters are not black. A. basalis is also nearly related to it, but is smaller (15-17 mm.), has the face silvery pilose, densely so on the clypeus ; the head smooth, impunctate, wings hyaline, &c.

Long. 17 — 19 mm. Similar to the preceding species, but smaller, with the pubescence shorter and sparser, and of a more silvery tint ; the wings without such a decided yellowish tinge, and with the nervures blackish ; the first abdominal segment is red, except at the apex, and the third antennal joint is shorter, not being twice the length of fourth. Mandibles broadly red at the base, which is striated ; clypeus punctured, densely covered with a silvery pubescence ; its apex with a broad shallow sinuation ; front and vertex shagreened, sparsely and shortly pilose. Antenna; with the base of first joint testaceous, the flagellum covered with a pale pile. Pro- and mesonotum strongly transversely striolated ; metanotum more closely and not so strongly ; scutellum strongly longitudinally striolated ; propleura perpendicularly striolated, meso- and metapleura obliquely rugosely striolated ; the raised part of the metanotum shield-shaped. The tubercles and the sides of the middle segment densely silvery pilose. The second joint of the petiole is black above at the base ; the apex has a silky pile ; the hind coxae are white with a dense silvery white pubescence ; the trochanters are red, blackish towards the base and apex, the anterior broadly black at the base ; the tips of four anterior tarsi and the posterior from the base of the second joint blackish ; spurs blackish. Alar cellules pretty much as in A. budd/ia. The ocelli do not form a triangle ; the anterior not being placed very far in front of the posterior. The clypeus and tegulse in some specimens are tes- taceous ; the apex of the second joint of the petiole may be black ; the basal joint of the antennae may be testaceous,, Hynienoptei'a Or'ientalis. 7 and the middle joints may show a tendency towards fuscous coloration. In size there is some variation. Ammopiiila nigripes, Smith. A specimen from Barrackpore agrees with Smith's description so far as it goes. It is fully one line longer ; the hair on the thorax is longish and tolerably thick ; the clypeus is broadly transverse at the apex, the sides being angled ; the mesonotum is furrowed in the centre ; the legs are thickly pruinose ; the second cubital cellule at the top is about one-fourth shorter than the third, and about equal in length to the space bounded by the second recurrent and second transverse cubital nervures ; the third cubital cellule is almost equal in length at top and bottom, and the third transverse cubital nervure is sharply elbowed a little below the middle. Ammophila atripes, Smith. The Barrackpore specimens of this species, as named by Smith, are uniform in coloration — black, the second joint of petiole is red beneath, the first joint black, the other seg- ments steel-blue ; the wings more or less fuscous, the nervures black. Face and clypeus densely covered with silvery white pile ; apex of clypeus transverse, the sides rounded ; vertex and front with scattered punctures, shining. Pro- and mesonotum strongly transversely striolated ; meta- notum more closely and not so strongly ; scutellum and post scutellum longitudinally striolated ; pleurae rugose. The pubescence on the thorax is short and cinereous ; the abdomen is thickly pruinose. At the top the second cubital cellule is about one-half the length of the third, and a little more than the space bounded by the second recurrent and second transverse cubital nervures ; the third cubital cellule is nearly equal in length at top and bottom ; the third transverse cubital nervure is elbowed near the middle. The 8 Mr. Cameron on female agrees in coloration, punctuation, and clothing with the male. Differs from A. nigripes in being longer, in having the hair on the thorax less dense and shorter, the clypeus more rounded at the apex, the mesonotum with the central furrow less distinct, the wings darker, and with black nervures. Barrackpore — common. B. mesonotiiui punctured. f^- Ammophila Vischu, sp. nov. Nigra, nitida, punctata; apice petioli, abdominisqiie segmentis i — 2, rufis ; alls fnscis. Long. 22 — 24 mm. Antennae stout, microscopically pilose. Face and clypeus covered with a silvery white pubescence ; the front and vertex bear long fuscous hair. Clypeus broad, flat, the apex margined, truncated ; sparsely punctured. Front depressed ; a distinct furrow down the centre ; rather strongly punctured ; the vertex with the punctures more widely separated. Thorax strongly punctured, the pleural and metanotum rugose ; scutellum with the punctures larger and closer than on the mesonotum ; post-scutellum rugose. Mesonotum with a distinct furrow, which becomes wider towards the apex, where it is nearly filled up by a keel. The pubescence is long and cinereous, long and dense on the pleurae ; sparser above. The tubercles, an oblique stripe on the pleurae and the middle segment laterally, densely covered with silvery pubescence. Second segment of petiole stout ; the extreme base black. Second segment above wider than the space bounded by the first recurrent and first transverse cubital nervures ; the third cellule much narrowed at the top, usually there not one-fourth of the length of the bottom. Tcguke black. The male has the clypeus produced and rounded at the apex, and is, as well as the face, densely covered with silvery pubescence. Hynnenoptera Or'iental'is. g A. punctata, Smith, is apparently closely allied to this species ; but no mention is made of the mesonotum being furrowed, and the metanotum is said to have a longitudinal carina in the centre ; the collar has "a minute tubercle in the middle," and the wings are hyaline. Petiole composed of one joint {Psanunop/iila). ■ Ammophila HIRTICEPS, Sp. nov. Nigra; longe nigra Jiirta ; abdominis segmentis 2 — ^ rufis ; alis fere Jiyalinis, apice fnnatis, nervis nigris. Long, fere 15 mm. Antennae stout ; pilose ; the third joint about one quarter longer than the fourth. Head hardly punctured ; covered with long and black hair ; the face and clypeus densely covered with silvery pubescence ; apex of clypeus broadly rounded, almost sinuated in the middle ; ocelli nearly in a triangle ; the posterior separated from the eyes by about the length of the third antennal joint ; front hardly depressed. Thorax somewhat punctured ; the scutellum apparently indistinctly longitudinally striolated ; metanotum obliquely striolated, furrowed down the centre, and with a keel in the centre of the furrow. The one-jointed petiole is a little longer than the second segment, and is covered with long black hair, the fifth segment is red at the base. Above the second and third cubital cellules are sub-equal, and the former above is about three-fourths of the space bounded by the recurrent nervures ; the third cellule below is about half the length of the second, and is rounded at the apex below ; the third transverse cubital nervure bulges outwardly on the lower half, then retreats towards the second cubital nervure, thus making the third cubital cellule wider below than above. Claws reddish. Owing to the matting of the hair on the head and thorax, I am unable to make out the sculpture of these parts clearly. The species is a true Psammophila. lo Mr. Cameron on Ammophila erytiirocephala, Fab. This large and striking species is a Parapsamniophila. The head is large ; the eyes reach onh- exactly opposite the level of the hind ocelli, the vertex being much more developed behind them than usual ; they are quite parallel, not converging at the bottom as in A. violaceipennis ; the antennae issue from nearl}- opposite their middle, and not so high up as in the latter species ; the clypeus does not project in the middle, and is truncated at the apex. The mandibles are very large and projecting, almost as in Ampulex. The neuration of the wings is very much as in ViolaceipeJinis. Antennae black, pilose ; the 3 — 4 basal joints red, the third is nearly twice the length of the fourth. ^AmMOPPIILA violaceipennis, i-/". 710V. Nigra ; scapo antennannn,petiolo pedibjisque, rufis ; coxis apiceque tarsoruni nigris, alls violaceis. $ Long. 29 mm. Head shining, sparsely punctured ; the clypeus and face covered with silvery pubescence ; the front and vertex with longish, blackish hair ; clypeus somewhat projecting ; the apex with a distinct margin, a little sinuated ; mandibles broadly red in the middle. The antennae incline to fuscous beneath, especially at the base ; the third joint is longer than the first and second joints united, and about one-fourth longer than the fourth. Thorax densely covered with blackish hair ; coarsely punctured ; the mesonotum rugo.sely striolated in the middle at the apex ; scutcllum coarsely rugosel}- striolated ; metanotum coarsely rugosely punctured in the middle, at the sides obliquely striolated ; the pleurae coarsely rugosely striolated. Pygidium broadly rounded,, pilose. Second and third cubital cellules above subequal ; the transverse cubital cellules elbowed towards the middle, thus making the third cubital cellule wider in the middle than at top or bottom ; the first recurrent nervure is recei\-ed Hymenoptera Orientalis. il before the middle of the cellule ; the second at nearly the length of the third cubital cellule at the bottom from the apex ; at the top the second cubital cellule is as wide as the space bounded by the recurrent nervures. This species belongs to Parapsammophila^ Taschenberg, which is chiefly distinguished from AmmopJiila and Psam- mophila by the tarsal claws being bidentate at the base. Pelopoeus.

Pelopoeus bengalensis. This is an external builder, erecting its nests on rough walls, or corners, on grass, or on leaves. When on a grass stem the mud is continued far up, thus breaking the out- line of the cell, which is in consequence not so readily observed. A solitary cell may be built, or over a dozen may be placed side by side, the whole being then covered well over with mud. (Home, Trans. Linn. Soc. VII. p. 163). Hymenoptera Orientalis. 13; Pelopeous madraspatanus. Of this abundant species (commonly called the mud- dauber) an interesting account is given by Home {Trans. Linn. Soc. VII., p. 161 — 163). In May, June and July the females are found congregating by small puddles near wells, treading the mud into little pellets of about the size of buck-shot, which, when ready, are brought in the mouth of the insect to the place where the nest is to be constructed. This is in the most various situations. In window-sills, in hollows in walls, in locks, in any cavity between the wall and door-frame ; in a depression on the floor, anywhere, in fact, inside or near a house. Home relates how one individual commenced to build in the corner of a door-frame, where it w^as crushed every time the door was opened. Six times did the industrious creature commence its habitation only to have it crushed every time. It takes about a day to complete a cell ; two, or three, or five are built together, the whole being then covered over with a smooth coating of mud, so that it looks like a dab of mud accidentally left on the wall. When the cell is finished it is filled with small spiders to the number of twenty. Spiders are the regular prey of the Pelopoens, but Home has also seen it store small green caterpillars. In the pupa state it remains from one to six months according to the season. Pelopeous bilineatus. Unlike P. Madraspatanus, this form does not frequent houses, but builds on hedges and trees, a favourite position being a fork in the bough of Lawsonia spinosa. As a con- sequence of the more exposed situation chosen for its nests,. these are much more solidly built. Smith thinks that P. bilineatus is only a form of Madraspatanus . 14 Mr. Cameron on Pelopoeus javanus. Wallace states {Jour. Linn. Soc. Zoo/. XL, p. 296) that this species enters houses where it constructs small earthen cells, which it stores with paralysed spiders as food for its young. According to Maurice Maindron {Ann. Soc. Ent. Fr. 1878, p. 390) the largest nests are 7 centimetres long by 5 in breadth ; contain five cells and are made of treaded mud, almost black in colour, but covered in parts by a layer ■of white earth. The largest and external cell is incomplete and is formed of a whiter earth than the others. In form the nests are irregular and arched ; and Wallace (/. c.) mentions that they may be plastered over with mud in an irregular manner, so that the shape is completely hidden. The cocoon is /» of an inch in length, and of a delicate brown colour. P. COROMANDELICUS. This species has frequently the scutellum and metanotum without the reddish spot. The clypeus is reddish towards the apex, which is incised in the middle. The mesonotum is transversely striated ; the scutellum finely longitudinally striated, but not nearly so strongly as the mesonotum ; the pronotum is depressed in the middle ; the second cubital cellule is not much narrowed above compared to the bottom, and is broad compared to the length ; the first recurrent nervure is received a little before the middle.

Rufa, ahdoniine negro-cceruleo ; alls fiavo-hyalinis, apice fiunatis, nervis nifo-testaceis. Long. 17 mm. Scape of antennae on lower side bearing short black, bristly hairs ; the second joint curved inwardly on the inner side ; the third thin, more than one-half longer than the fourth. Head almost shining, sparsely covered with black hairs ; the front and vertex closely punctured ; the face and clypeus more shining, imperceptibly punctured ; the labrum and clypeus fringed with short black hairs, the latter with two short stumpy teeth on either side of the middle ; a thin furrow runs down from the vertex to the ocelli ; the central part of the vertex slightly raised, but not forming a distinct field. Mandibles bearing long black hairs ; and some stout furrows towards the middle tooth ; the apex is black. Palpi reddish. Thorax shining, sparsely covered with short black hair ; the pronotum strongly striolated ; the top shining, impunctate, and with a wide and deep furrow in the centre. Mesonotum with scutellum very shining, almost glabrous, sparsely and minutely punctured. Median seg- ment striolated, depressed in the centre and with a furrow along the sides above; the apex rounded,semi-perpendicular, and bearing long black hair ; the oblique furrow on pleura is wide and deep, and is divided at the top by an oblique raised projecting part. Abdomen shining ; sparsely punc- tured ; pygidial area covered with long black hairs. Legs longish ; the hinder row of spines on the hind tibiae black ; the others reddish, and there is a tuft of black spiny hair on the apex of the hinder femora. Tarsal spines thick and stout ; metatarsal brush short, thick, reddish. There are some stiff black hair on the hinder tarsi before the claws. Second cubital cellule a little wider at the bottom than at 5o ' Mr. Cameron on the top, which is a little longer than the top of the third cellule, the latter being very much narrowed at the top, the bottom being more than twice the length of the second cellule, and its apex reaches near to the apex of the radial cellule. The first recurrent nervure is received a little beyond the middle of the cellule ; the second quite close to the second transverse cubital nervure. Sphex aurulenta, Fab. A variable species. The commonest Bengal form is the var. aurulenta ¥a.h. = Fabricii, Dhm. = /erru^inca, Y.&^.^godcffroyi, Saussure. The var. sericea, l^Qp. — Lcpek- tierii, Sauss. also occurs ; but I have not seen any Indian specimens that could be referred to the var. scricca Fab. = fcrox Smith, a form chiefly, distinguishable from var. Lepe- letierii by the hair on the pleurae and middle segment being blackish-brown. The $ from Bengal is the typical lincola Lep. The hair on the head and thorax is hoary white; the wings are hyaline, smoky at the apex ; the abdomen black, the base and the segments at the apices above and beneath reddish ; the tegular and legs are blackish. A $ var also is met with ; it has the legs red, except at the base and the tarsi : the tegulae are red ; the hair cinereous ; and the abdomen may be red from the petiole, or red onK- at the base as in the typical lincola. This does not quite agree with the description of *S'. vclox, Smith, which has the hair fulvous. - Sphex erytiiropoda, sp. nov. Nigra^ fusco pubescens ; pcdibus rujis ; basi aplceque tarsoruni, nigris ; alls flavo-fij'alinis, apice fumatis. Long. 15 — 18 mm. Antennae of the usual length ; covered with a sericeous pile ; th:3 third joint not much shorter than the fourth and fifth united. Head .shining, bearing a scattered punctua- Hyimnoptera Orientalis. 21 tion ; the front and vertex sparsely covered with longish blackish hair ; the cheeks, face, and clypeus densely covered with silvery pile and with longish fuscous hair. Eyes slightly converging beneath ; the ocelli hardly forming a triangle ; a furrow along their side, the furrows meeting into a V-shaped depression, which has a sharp raised pro- jection in its centre. Clypeus broadly rounded, the apex depressed and with a short incision in the centre. Thorax sparsely covered with a fuscous to black pubescence ; the pubescence on the middle segment dull fulvous. Pro- notum with a distinct and broad depression in its centre ; the mesothorax is also slightly depressed in the centre, and the scutellum and post scutellum are distinctly and broadly furrowed. Median segment transversely and regularly striolated ; a wide and deep furrow in its centre at the apex, and there is an elongated pear-shaped depres- sion on the upper part. Abdomen shining, with a plum- beous tint ; the petiole covered with long black hair, and a little longer than the coxae ; the pygidial area shagreened, and with a few scattered punctures. Legs with the coxae, trochanters and four apical joints of the tarsi and the spines on the hinder tibiae, blackish. In the colour of the body and pubescence this species comes nearest to 8. rufipennis, but is readily known from it by the reddish legs. It can hardly, I think, be an extreme variety of 8. auriilenta, from which, apart from the dif- ference in coloration of the head and thorax and their pubescence (comparing the females), it differs in having the pronotum more distinctly raised above and separated from the mesonotum, besides being broadly furrowed in the centre ; the mesonotum and scutellums are also broadly furrowed, and the median segment, instead of having three or four raised ridges, is uniformly and regularly striolated. The amount of black on the tarsi varies, as does also the colour of the spines and wings, the latter in one specimen 22 Mr. Cameron on having the yellow tint very feebly developed. The tegulae are for the greater part black. I have seen four females in the Calcutta Museum col- lection. Sphex rufipennis, Fab. This species appears to be a common one in India. The colour of the wings varies, the base, especially in the form diabolicus, Smith, being more or less blackish, and the yellow tint is something suffused with fuscous. S. rufipennis has been recorded from South America, but inasmuch as the $ genitalia differs considerably from that of the Indian form, it is probable that the American form, notwithstanding its almost identity in coloration, size, &c., really represents a different species, which I have provisionally named yst.

The ? has the clypeus convex, ending in a rounded point before the apex, from which point it goes obliquely to the labrum, ending on Hynienoptera Or lent a lis. 13 either side in a blunt tooth, the teeth forming with the apical point a triangle. Eyes almost parallel. Ocelli not forming a triangle, the hinder separated from the eyes by the length of the second and third antennal joints united ;, and from each other by not very much more than the length of the second joint. The third antennal joint is fully one half longer than the fourth, and not much shorter than the first. There is a short blunt triangular tooth on the hinder edge of the mesosternum. The punctuation of the head is moderate ; on the thorax much coarser and rugose ; the metanotum is rugose ; the triangular area on the median segment is large, transversely striated, and indistinctly furrowed down the middle. The pygidial area is opaque, irregularly punctured ; twice broader at the base than at the apex, the contraction taking place beyond the middle ; the apex rounded, the sides punctured, the hair fringe long, dense, and fulvous. Hypopygium finely punctured, opaque ; the incision triangular, reaching a very little beyond the middle. In the $ the clypeus is equally convex, bluntly keeled in the middle, the apex broadly rounded ; the triangular area on the median segment is longitudinally striolate, the striae wide apart ; the pygidial area is of equal width and is punctured irregularly. In both sexes the petiole is wider than long, sparsely punctured ; the sculpture on the other segments is weak and becomes almost obsolete on the fifth segment. ^^Cerceris Rothnevi, sp. iiov. (PI. X., f 3, a, b). Ferruginous, the vertex for the greater part black ; the fourth and apical segments of abdomen dark piceous ; the scape beneath, the cheeks, clypeus, basal half of mandibles, tegulae, a line on the pronotum, tubercles, scutellum, meta- notum, the base of second abdominal segment, the third segment, except on semi-circular space at the base, the fifth 14 Mr. Cameron on segment, the basal two ventral segments and the penulti- mate on either side and the legs, yellow ; the femora lined with fuscous above. Wings clear hyaline, the apex infus- cated, the stigma and nervures fuscous. Body covered closely with whitish pubescence, which is especially thick on the head. The punctuation of moderate intensity ; the trigonal area of median segment smooth, impunctate, and there is an impunctate space on the sides of the median segment and on the metapleura. Clypeus moderately convex, the apex transverse, with a short blunt tooth at either end. Hinder ocelli separated from the eyes by the length of the third antennal joint, and by a slightly less distance from each other. Eyes a little diverging beneath, the orbits behind clearly margined. The scutellum is smooth, with a border of widely set apart punctures ; the metanotum is impunctate. The furrow down the centre of the trigonal area is shallow ; the margin of the area is crenulated. Petiole a little longer than wide. Pygidial area elongate, narrow, rounded at the apex ; the base narrower than the apex ; the top closely and finely transversely rugose ; the hair fringe white ; hypopy- gium not incised. Antennae blackish above ; the flagellum obscure rufous beneath. Second cubital cellule with the peduncle not much shorter than the width of the cellule itself; the first recurrent nervure is received in the basal third ; the second a little beyond the apex of the cellule, and almost interstitial. Length lo mm. This species comes nearest to C. instabilis ; but may easily be known from it by the clypeus not being incised ; by the punctuation being not so strong, especially on the scutellum and median segment ; by the smooth, not rugosely punctured, trigonal area, by the narrower, longer, straighter, pygidial area, which in instabilis is wider at the base than at the apex, it bearing also large punctures, and by the shorter second cubital cellule. Hymenoptera Orientalis. 15 CerCERIS INSTABILIS, Smith, (PI. X. f. 4 — 4 a, b). A common and variable species, especially as regards the amount of black on the thorax and abdomen. The $ is C. velox, Smith. L- 6ERCERIS PULCHRA. (PI. X. f. 5, a, b.) Black, the scape beneath, the cheeks, clypeus, mandibles except at apex, two lines on the pronotum, tegulae, meta- notum, a mark on the base of the second abdominal segment, the third segment except the base in the centre ; the fifth segment, the second ventral segment laterally, and the legs, yellow ; the petiole and second abdominal segment ferruginous, except the yellow and a black mark on the latter. Clypeus a little gaping at the apex, which is black and incised. Eyes parallel. Hinder ocelli separated from the eyes by near the same distance they are from each other. Body covered with longish pale fulvous pubescence, almost golden on the face; the punctuation is strong and coarse ; the scutellum strongly punctured. Trigonal region rugose, and with some stout keels ; the central furrow deep. Petiole distinctly longer than broad ; pygidial area elongate, gradu- ally narrowed towards the apex, which is almost transverse, but with the edges rounded ; the incision in the hypopygium is a little longer than wide, rounded at the base, and becom- ing wider towards the apex ; the top of the pygidial area is irregularly punctured, without a hair fringe, and covered with long pale pubescence. The coxae are black at the base ; the hinder femora are for the greater part black ; the hind tibice are fuscous on the outer side at the apex. Antennae rufous ; the third joint curved, twice the length of the second and longer than the fourth. The wings are suffused with fuscous ; the apex broadly smoky ; the second cubital cellule has the peduncle not much shorter than the cellule ; the first recurrent nervure is received in the basal fourth ; the i6 Mr. Cameron on second a little beyond the second transverse cubital nervure ; the nervures fuscous. The $ has the clypeus at the apex broadly rounded ; the black on the second abdominal segment is more extended ^ the fifth segment is black and the sixth yellow ; the pygidial area is punctured strongly, narrowed a little at the base, and with the apex transverse. Length 7 — 8 mm. This species is represented by numerous examples of both sexes, and it appears to be tolerably constant in coloration. Vischnu may be known from it by the black face, by the truncated clypeus, by the absence of yellow on the thorax and on the second abdominal segment ; dentata by the teeth on the thorax. ^Cerceris Visciinu. (PI. X., Fig. 7 — ya, b.) Black ; the scape, the apex of the clypeus, the antennal ridge, a mark on the cheeks, a small mark on the sides of the pronotum, the apex of the third abdominal segment, a mark in the centre of the fifth, the four anterior tibije in front, the four anterior tibiae, the base of the hinder, pale yellow ; the femora beneath and the hind coxae rufous ; the petiole and base of second segment ferruginous. Clypeus with the apex projecting, but not sharply and with a slight incision. Ocelli in a curve ; the posterior separated from each other by more than the length of the third antennal joint and by its length from each other. The face covered with a silvery pubescence, the rest of the bod}' with pale hair ; the punctuation close, rugose. Trigonal area not very clearly defined, rugosely punctured. Petiole a little longer than broad ; pygidial area rugose, slightly narrowed towards the apex, which is bluntly rounded ; the hair fringe dense, obscure fulvous ; the incision in hypopygium a little longer than broad, the base rather sharply pointed. Wings clear hyaline, the apex smoky ; the second cubital cellule longer than broad ; the recurrent nervure received shortly Hymenoptera Orient alls. 17 before the middle. The antennae have the flagellum pale fulvous beneath ; the eyes are parallel. The $ has the clypeus broadly truncate at the apex in the middle, and with the lateral laminae pale ; the clypeus wants the yellow mark ; the petiole is black ; otherwise as in ? except that it is the 6th abdominal segment which is marked with yellow. Length ? nearly 9 mm ; $, 7 mm. A distinct species. What appears to be this species has a small yellow mark at the base of the abdomen, the petiole beneath and later- ally and the base of the second segment are rufous and there is a small white mark on the base of the latter. Xerceris tristis, sp. 710V. (PI. X. f 7, a, b). Eyes parallel. Ocelli not forming a triangle ; the posterior separated from the eyes bynearlythe lengthof the second and third joints united and from each other by less than the length of the third. Middle lobe of the clypeus convex, gaping at the apex, which is broadly and narrowly incised. Punctuation of head close and rather strong ; the face densely covered with silvery hair. Head below the antennce and the orbits for the length of the scape above the base of the antennae, and the mandibles, except at the apex, yellow. Extreme apex of clypeus black. Thorax strongly punctured, more coarsely on the pleurae ; the tegulae, a lineoneithersideof thepronotum, and metanotum, yellow. Trigonal area obscurely aciculated, the sides punctured irregularly ; the central furrow crenu- lated. Petiole longer than broad, distinctly bulging out at the sides ; the segments with a moderately strong punctua- tion ; a mark broader than long on the base of the second segment ; the apex of the third segment (narrowed in the centre) and a narrower belt on the fifth,also narrowed in the centre, yellow. Pygidial area elongated, narrower at base than at apex, the latter bluntly rounded ; the surface irregu- larly rugose. Incision in hypopygium broad, a little longer i8 Mr. Cameron on than broad, gaping at the apex, the base broadly rounded. Lateral hair fringe sparse, silvery. Legs black ; the apex of coxae and trochanters ; the greater part of the femora beneath ; and the tibiae and tarsi, except the apices of the posterior, yellow. The $ has the clypeus slightly convex ; the apex pro- jecting in the middle, black and with a short broad, blunt tooth in the middle. The coloration is as in the ? except that the fifth segment is entirely black and the sixth nearly entirely yellow. Pygidial area of equal width throughout ; depressed before the apex, shining and sparsely punctured. Length 7 — 9 mm. May be known from C. novarcB by the median segment wanting yellow marks ; by there being only a central basal yellow mark on the second abdominal segment; by the legs being broadly black at the base, by the third joint of the flagellum being distinctly longer than the fourth ; by the central lobe of clypeus being roundly convex and gaping at the apex, &c. Cerceris fervens. Smith. It is probable that this will prove to be identical with C. novarce. So far as the description of the 9 goes the only difference is that m fervens there are two lines on the scutellum ; but in both the females of NovarcB I have examined, there is a minute yellow mark on either side of it. Smith's description of the $ differs moreover, it having the sixth segment (not the fifth) yellow marked ; and apparently the median segment wants the yellow marks. Smith, I may add, named, in Mr. Rothney's collection, the $ of the species I have called ViscJimi, fervens ; but it does not agree with the description of fervens ; and my specimen is certainly not the $ of Novarce. It is possible that Smith has assigned the wrong $ to \C\s fervens. Hymenoptera Orientalis. 19 <-€erceris NOVAR./E, Sauss., (PI. X. f. 8, a, b). Clypeus flat, slightly convex in the middle ; the apex projecting a little beyond the lateral pieces ; the apex trun- cated, but with the sides rounded. Eyes a little converging beneath. Ocelli not forming a triangle, the anterior being too much in front of the posterior ; the posterior separated from the eyes by a little more than the length of the third antennal joint, and by its length from each other. Front and vertex strongly punctured ; the face and clypeus with shallow punctures. The face, oral region, antennal keel and the orbits to the length of the scape above the base of the antennae; the mandibles, exceptattheapex, and aspot behind the eye near the top, yellow. The vertex is sparsely pilose. Thorax more strongly punctured than the head; thepunctures larger and wider apart, the pleurae more coarsely punctured than the mesonotum.

Petiole longer than broad, slightly bulging out at the middle, coarsely punctured. The other segments are also strongly punctured. Pygidial area an elongated oval, narrowed at base and apex, the surface irregularly rugose.

The legs are yellow, 20 Mr. Cameron on except the apical half of the posterior femora and tibise. The scape is yellow; the flagellum fulvous beneath; the third and fourth joints are sub-equal. The $ is similarly coloured, except that the mesopleurse want the yellow mark and the scutellum is entirely yellow. Length 7 — 10 mm. XlERCERIS Wroughtoni, sp. uov. (PI. X. f. 9, a, b).

The second recurrent nervure is almost interstitial ; second cubital cellule rather shortly pedunculated ; the apical nervure longer than the basal. The wings, although, dark smoky throughout, are darker along the radial cellules. Length 8 mm. * I suspect that the rufous tint is caused by cyanide of potassium. 26 Mr. Cameron on Cerceris interstincta, Fab. What this species may be is rather doubtful. On the whole the description fits best with the $ of humbertianay but it differs from it in no mention being made of the two marks on the median segment. With this exception, how- ever, the description, so far as it goes, suits Jmnibertiana fairly well. Cerceris dissecta. Fab. I am quite unable to recognise this species from the description. It may be added that neither Smith nor Schletterer includes this species in their Catalogues. The description of the Fabrician species are subjoined.

Petiole broader than long. Pygidial area narrowed a little at base and apex ; the apex rounded ; the hair-fringe dense pale fulvous ; incision in hypopygium reaching near to the middle ; there is a tuft of hairs on the apex of the segment at the sides. The second cubital cellule forms almost a semi-circle ; and receives the recurrent nervure near the middle. ,^-<;erceris nebulosa, sp. nov. (PL X., f IS, a, b.) Eyes slightly diverging beneath. Ocelli hardly forming a triangle ; the posterior separated from the eyes by fully the length of the third antennal joint, and by the length of the fourth from each other.

The hinder ocelli are separated from them by a little more than the length of the third antennal joint, and by nearly the same distance from each other. The middle of the clypeus projects considerably, the projection almost truncated at the apex, except that there is a waved projection in the middle ; the sides of the projection are obliquely curved. The lateral hair fringe is dense and golden. The third antennal joint is a little longer than the fourth and attenu- ated at the apex. The puncturing on the top of the head is very deep and coarse, on the thorax it is not quite so strong. The trigonal area of median segment is smooth, shining, and impunctuate, and has very narrow and in- distinct furrow down the middle. Pygidial area bearing large oval punctures; it is a little narrowed and truncated at the apex and has there a golden pile. The petiole is broader than long and rugosely punctured. The other segments bear large, separated punctures of moderate length. May be known from the S of vistabilis by the clypeus of the latter not projecting so squarely in the middle ; by the trigonal area being coarsely longitudinally striolated ; by the petiole being much narrower, being clearly longer than broad ; by the yellow band on the vertex, &c. Apparently a common species. Cerceris EMORTUALIS. I should say, judging how very variable Jiunibertiana is, that this will prove to be a variety of the latter. Hyvienoptera Orientalis. 29 Cerceris hilaris, SmitiL (PI. X., f. 17, a, b.) The clypeus is longer than broad, and becomes gradually broader towards the apex ; the five basal joints of the flagellum of the antennae are rufous, and the remaining joints are rufous beneath ; the third joint is slightly curved, and about one-third longer than the fourth ; the trigonal area is coarsely longitudinally striolate; the hypopygium is transversely rugose, and narrowed gradually towards the apex, and rounded there.

Psen erraticns, Smith {Proc. Linn. Soc.

I have experienced considerable difficulty in identifying the numerous species of this large family, described by the late Mr. F. Smith, of the British Museum. This is more particularly the case with the black species, and with those related to Salius flavus, Fab, These latter I find to be especially puzzling, from the fact that the same type of colouration is found in two of the sections of Salius and in Pompilius. I have myself, with the aid of numerous examples, come to definite conclusions as to the limits of the species with those of the y7crw/j-colouration ; but I am in so much difficulty about the nomenclature, that I have decided to leave them over until I have had an opportunity of examining Smith's types. I am the more inclined to do so from finding in Mr. Rothney's collection a Ponipihis, and a Salius named dorsalis, Lep., by Mr. Smith. As regards the genera, I have adopted them as defined by Kohl in his paper " Die Guttungen der Pompiliden " in Verh. s.-b. Ges. IVien, 1884. The species of FonipilidcE, as a rule, store their nests with spiders ; but very little is known about the habits of the Indian species. Major Bingham describes the nest of Fompilus bracatus as a " burrow in the ground at the foot of a large fern," and he observed it provisioning its nest A I 432 Mr. Cameron oi with a small cockroach. P. Greeinwa-s reared by Mr. Green from a cocoon in what had evidently been a large spider's nest between two leaves ; and he surmised that the grub had been feeding on the spider's eggs. Ceropale.s.

PSEUDAGENIA CAERULEUS, Smith. A specimen from Barrackpore is probably this species ; but the description is rather incomplete. The clypeus at the apex is broadly rounded, the sides obliquely truncated ; the ocelli in a triangle and separated from the eyes by a somewhat greater distance than they are from each other ; occiput slightly concave; sides of pronotum rounded; shorter than the head ; second and third cubital cellules subequal ; the first recurrent nervure received shortly before the middle of the cellule ; the second about half the length of the transverse cubital nervure from the base. I cannot see the "fuscous cloud transversing the externo-medial nervure," nor "a faint cloud" in the second submarginal cellule. The apex of the hind femora is black, a fact not mentioned by Smith for his cccrulea. It is possible that my specimen may be cyaiicus, Lep., but that has the third cubital cellule " plus grande que la deuxieme." The median segment at the apex rounded, transversely striated, and having a gradually-rounded slope to the apex ; the apex also having a tuft of white hair on either side ; the upper part of metapleurai obliquely striated ; the long spur of the hind tibi£e does not reach the middle of the metatarsus ; the Hymenoptera Orientalis. 439 base of the latter with a thick hair brush ; the other joints with short spines beneath ; the fore tarsi pilose beneath. PSEUDAGENIA FESTINATA, Smith. (PI. III. f. 3). This species, I consider, identical with P. alaris, Sauss. Smith's type is smaller, and the wings have not the yellowish tint quite so marked. PSEUDAGENIA CEL^NO, Smith. A $ from Barrackpore, is, perhaps, this species — at least it agrees fairly well with the description so far as that goes. The eyes distinctly converge towards the apex ; the clypeus is transverse at the apex ; the sides being oblique ; the ocelli form a triangle, and are separated from each other by a perceptibly less distance than they are from the eyes ; the second and third cubital cellules at the top and bottom are subequal ; the first recurrent nervure is received a little before the middle ; the second in the basal third of the cellule ; the nervures are pale testaceous. From alaris it is easily known by the truncated apex of the clypeus. The long spur of hind tibiae does not reach the apex ; the meta- tarsal brush slight. > PSEUDAGENIA ARIEL, Sp. nov. Black, shining, pubescent, eyes distinctly converging beneath, the space separating them at the top being ■distinctly greater than at the bottom. Ocelli in a triangle ; the hinder separated from each other by a less distance than they are from the eyes. Clypeus convex, the basal half laterally oblique ; the apical curved, terminating in a blunt point. Occiput bluntly rounded. An indistinct furrow runs from the ocelli to the antennae. The head is convex in front, shining, finely punctured, sparsely covered with long silvery hairs ; the cheeks and clypeus bear a silvery pubescence ; antennae longish, stout, pruinose, tapering 440 Mr. Cameron on towards the apex. Mandibles at the base finely rugose. Pronotum broad, broadly rounded in front, behind concave. Median segment short, with a rather abrupt slope, trans- versely striated. The thorax above in front is shining, minutely punctured, laterally opaque, alutaceous, the median segment transversely striated.

Occiput slightly concave in the middle. The front strongly aciculate ; the vertex shining, almost impunctate. The head, except on the vertex densely covered with a silvery pubescence ; the vertex with a few fuscous hairs ; the lower and outer orbits with some long silvery ones. Pronotum shorter than the head, roundly narrowed towards the head, shallowly concave behind. Pro- and meso- thorax alutaceous ; the median segment with a rounded slope, irregularly transversely striated ; deeply furrowed down the centre, the sides covered with long whitish hairs. Abdomen shining ; pruinose, having an olive tint, the petiole with a distinct neck. Radial cellule wide, angled where the cubital nervures are received ; the second cubital cellule at the top distinctly shorter than the third, especially on the lower side ; the first and second transverse cubital nervures with Hyvienoptera Orientalis. 441 a slight oblique curve ; the first recurrent nervure is received a little beyond the middle ; the second at a less distance from the base.

Black, densely pruinose, the hinder femora red, wings hyaline, the nervures black. Eyes curved, converging beneath and at top. Ocelli separated from the eyes by a somewhat greater distance than they are from each other. Clypeus broadly convex, broadly rounded at the apex. Occiput slightly convex, the sides rounded. A shallow furrow runs down from the ocelli. Head opaque, aluta- ceous ; the clypeus and cheeks densely covered with a silvery pubescence ; the front and vertex sparsely silvery pubescent, shewing fuscous hairs. Antennae stout, involute. Thorax alutaceous, covered with a silvery pubescence ; the pleurae and median segment with long soft white hairs ; the pronotum short, bulging out roundly laterally, behind slightly curved, angled in the middle. Median segment obscurely transversely striolate, indistinctly channelled down the centre. Petiole with a distinct neck, becoming gradually widened towards the apex ; the abdo- men shining, laterally, and at the apex densely pruinose ; the apical segment impunctate, the apex with fulvous hairs. Radial cellule elbowed slightly where the first and third transverse cubital nervures are received ; the second cubital cellule a little shorter than the third at top and bottom ; 442 Mr. Cameron on the first recurrent nervure is received a little in front of the middle of the cellule ; the second in the basal third. Legs elongated, pruinose ; the long spur of the hind tibiae does not reach the middle of the cellule. The abdominal seg- ments are testaceous at the apex. It is probable that this is P. tinctiis, Smith, with which it agrees in colouration (the only point noted in the descrip- tion), except that I fail to notice any trace of " green tinge " about the head and thorax. The four anterior femora may be entirely black, or more or less reddish. It is probably varipes, Dbm. Salius, Fab., sec. Kohl. SalzKS, Fab., Syst. Ficz., 124; Kohl, VerJi. z-b, Ges. JVz'en, 1884,43.

Hymenoptera Orientalis. 461 POMPILUS CIRCE, Cam. (PI. Ill f. 5). This is the most conspicuous species of the section. The collar is more elongated, is transverse at the apex in the middle, but curves round to the tegulag at the sides ; the clypeus is rounded ; the ocelli small, in a curve, and separated from each other by a much greater distance than they are from the eyes. __j'OMPILUS PEDALIS, Sp. nov. Black, the basal two segments entirely, and the basal two-thirds of the third, red ; the head and thorax densely covered with grey pile ; the wings fusco-violaceous, the base to the transverse basal nervure subhyaline. Eyes arcuate, distinctly converging beneath. Ocelli large, in a curve, separated from each other by a much greater distance than they are from the eyes ; the anterior in a pit ; and an oblique short furrow runs from the posterior, Clypeus short, subarcuate. The head almost hoary with a greyish- white pubescence ; on the top it is shorter, convex in front, concave behind. Occiput convex. Prothorax longer than the head, longer than broad, narrowed towards the head ; at apex angled in the centre. Median segment as long as the prothorax ; with a very slight slope above, the sides at the apex projecting into a longish sharp triangular tooth. Abdomen sessile, longer than the head and thorax united ; pruinose, the apical segment impunctate. Antennae short, about as long as the thorax, stout. Legs densely pruinose ; the hinder tibize sparsely spined ; the hind tibise not much longer than the metatarsus ; the long spur of the hind tibiae reaches to the middle of the latter. For wings see fig 6, pi. III. Claws bifid at apex ; the tarsi without a brush. This species differs from the other species here noticed, in the eyes being more arcuate at the top and converging much more at the bottom. 462 Mr. Cameron on POMPILUS (FERREOLA) ARIADNE, Sp. IIOV. (PI. III. f. 7, yd). Black, the spurs white, palpi yellow, mandibles reddish, wings subhyaline. Head smooth and shining, sparsely pubescent ; eyes arcuate, equally converging at top and bottom ; ocelli large, in a curve ; the posterior separated from each other by more than twice the distance they are from the eyes. Head convex in front, concave behind ; antenna; placed immediately over the clypeus, over which the front projects ; clypeus rounded at the apex. Prothorax quadrate, longer than the head, not narrowed towards the head ; behind almost transverse. Pleura; compressed, impunctate, almost glabrous. Median part of scutellum broad, a little narrowed towards the apex : median segment longer than the mesothorax ; depressed in the middle at the apex ; the lateral projections acuteh- triangular ; the apex bearing depressed longish hairs.

A very distinct little species. /"POMPILU.S (FeRREOLA) HECATE, Sp. 710V. (PI. \\\. f 8). Black, pruinose, the face densely covered with a silvery pile, the wings hyaline, the apex infuscatcd. Eyes broadly arcuate, a little converging beneath ; ocelli large, almost forming a triangle, the posterior separated from each other by a greater distance than they arc from the eyes. Clypeus short, transverse, the sides rounded. Head behind very little developed, and almost transverse. Prothorax not much longer than the head ; almost transverse behind, not much narrowed in front. Median part of scutellum narrowed Hymenoptera Orientalis. 463 distinctly toward the apex ; median segment longer than the mesothorax, depressed in the middle at apex ; the laterally- produced angles broad, short. Abdominal segments with a broad belt of silvery pruinose pubescence. Legs moderately long ; the hinder tibisD with few spines — longish and black. The transverse basal nervure is not interstitial ; for neuration, see pi. III. f 8. Length, 7 mm. Hab. Barrackpore. From P. WrougJitoni which it resembles in colouration it may be known by being stouter, by the head being longer, by the eyes being nearer each other at the top ; by the pronotum not having such a gradual slope to the head, and almost transverse behind, by the abdomen being shorter and broader and stouter. ^POMPILUS (FERROLA ?) ROTHNEYI, Sp. nov. (PI. III. f 9). Black, pruinose with a plumberous hue, the apex of the abdominal segments broadly black, not pruinose, the pruin- osity giving the insect a greyish hue ; wings yellowish hyaline, the apex infuscated. Eyes a little converging beneath, ocelli moderate, not in a triangle ; the posterior separated from each other by a somewhat greater distance than they are from the eyes. Clypeus equally convex all over, short, broad, the sides obliquely truncated, the apex almost transverse ; labrum half the length of the clypeus, bluntly rounded. Occiput transverse, very little developed behind the eyes. Antennae moderately stout, the scape greyish pruinose. Prothorax longer than the head, not much narrowed towards the head, the sides a little convex, at apex arcuate. Median segment concave at the apex ; the sides terminating in stout, somewhat triangular projections, the apex with a thick fringe of pale hair. Abdomen subsessile. Radial cellule short, A3 464 Mr. Cameron on broad in the middle, the basal abscissa of the radius a little longer than the second, which is straight, oblique and not curved. The second cubital cellule at the top more than twice the length of the third ; at bottom not much longer than it ; the third cellule very much narrowed at the top ; the transverse cubital nervures being almost united ; the first recurrent nervure received quite close to the apex of the wing ; the second a little before the middle ; it is elbowed in the middle. Legs densely pruinose ; the spines long ; the long spur of the hind tibia; reaching before the middle of the metatarsus : the claw with a blunt, thick subapical tooth. This species forms a transition to Fej'reola^ the apex of the median segment being only moderately concave and hardly dilated at the sides ; the antennae, too, are higher up over the clypeus, and the anal nervures in the hind wings are received beyond the cubital. In one example the third cubital cellule is distinctly petiolated. Length 12 mm. P. WrongJitoni has the apex of the median segment more as in the typical Ferreola, i.e., it is produced laterally, but not quite so much as in, say, Circe, it forming, in fact, a regular curve, and it is also depressed in the middle ; the abdomen is compressed, the anal nervure in the hind wing is interstitial ; the antennae are placed immediately over the clypeus ; the head is very little developed behind the eyes ; the basal nervure is not interstitial ; the centre of scutellum not much, if any, narrowed towards the apex — the pubescence on the edge of the pronotum forms a whitish band. ^PoMPiLus Wroughtoni, sp. nov. (PI. III. f. 10). Very similarto P. RotJineyi, havingthe same greypruinose vesture, with the abdominal segments grey and black ; and the apex of the median segment concave, the head very Hymenoptera Orien talis. 465 little developed behind the eyes and the abdomen subsessile ; but is smaller, narrower, and more slender ; the wings are subhyaline throughout, not yellowish or infuscated at the apex ; the second cubital cellule is much longer at the bottom compared with the third ; the third being of the length of the space bounded by the first transverse cubital and the first recurrent, the latter being received at a greater distance from the transverse cubital ; the second recurrent is received in the apical fourth of the cellule, not before the middle, and lastly the long spur of the metatarsus reaches almost close to the apex of the metatarsus. -^ PoMPiLus Delhiensis, sp. uov. (PI. III. f 11). Black, densely covered with a silvery pubescence, espe- cially thick on the face, median segment and on the apices of the abdominal segments ; wings yellow, a broad fuscous band at the radial cellule.

Is very nearly related to P. Rot/meyi, which it also resembles in having the apex of the median segment sub- concave ; but differs in the wings having the apex hyaline, the cloud not extending to it ; the third cubital cellule is much wider at the top, in the radial cellule being longer and much narrower ; in the prothorax having the sides convex, in its apex being transverse, not arcuate ; in the scutellum being shorter, broader, and not much narrowed towards the apex, and in the white spurs and base of hinder tibiae, the tarsi, too, being much more thickly spined and fringed beneath. - POMPILUS HERO, sp. )10V. (PL III. f 1 2).

In one specimen the hinder tibiae are whitish-yellow at the base, the spurs being also of this colour. ' FOMPILUS INCOGNITOS, Sp. 710V. (PI. III. f. 1 3). This species agree in the colouration of the body, legs, and wings with P. pedestris^ Smith — having the body densely cinereous pruinose, the hind femora and tibiae red, the wings fusco-hyaline, deeply infuscated at the apex, and the abdomen with cinereous bands ; but it must be, I should think, distinct, e.g.^ although the apex of the median seg- ment is truncated, yet it can hardly be said to be " produced laterally, forming obtuse tubercles " ; and the third cubital cellule is called " subtriangular," while here it is distinctly petiolated and not sub-triangular. Eyes distinctly converging beneath ; ocelli separated from the eyes by about the same distance they are from each other. Clypeus a little convex, short, broad ; the apex transverse. Head very little developed behind the eyes : the occiput a little concave.

Legs pruinose ; the spines long, black ; the base of the hind femora and apex of the tibial black ; the long spur of the hind tibiae reaches to the middle of the metatarsus. The cloud in the fore wings commences at the apex of the radial cellule. What is probably a variety has the hind tibiae black ; this form being also smaller. Length, 12 mm. POMPILUS VIVAX, sp. nov.

Black, the third and following segments, pale fulvous, and covered with long fulvous hairs ; the wings deep violaceous. Head and thorax marked with large, clearly- separated punctures, the punctures on the head and pleurse smaller than on the mesonotum ; the front above and between the antennze raised ; the apex slightly incised ; the surface longitudinally punctured ; and above it is an impunctate border, which extends to near the middle of the eye incision. The front ocellus in a pit. The mesonotum has the furrows slightly curved, and extending from the apex to a little beyond the middle ; the apex of the scutellum is impunctate, and has a short longitudinal channel in the centre at the apex. The median segment shallowly concave at the apex ; the sides convex ; there are two converging furrows in the middle ; the space on the outer side of these at the base being impunctate. Abdomen punctured like the thorax ; the hairs on the basal two segments black ; and they have a bluish tinge ; the base of the third segment is black, the black being dilated in the middle. The antennae bare, dull black ; the joints not dilated ; the third joint distinctly shorter than the fourth. The second cubital cellule is dilated at the top ; the transverse cubital nervures bulging out. Length, 25 mm. Allied to analis and crytJirosovia, but easily known by the fulvous, not red, apex of abdomen ; differing otherwise in the head being much more strongly punctured, this being also the case with the thorax.

The clypeus impunc- tate, with a row of punctures round the apex ; the vertex impunctate, except a semi-circle of punctures round the hinder ocelli to near the eye incision ; front strongly punctured above the antennae, and there is a row of punctures at the edge of the vertex, the front densely covered with blackish, the cheeks and outer orbits with greyi.sh, hair. Thorax moderately strongly punctured, Hymenoptera Orientalis, ly except on the mesopleurK behind the margin of the propleurae, the metapleurse at the base, and the centre of the mesonotum ; the latter having the punctures sparser; and with the parapsidal furrows deep, and reaching from the apex to beyond the middle. Scutellum sparsely punctured ; the sides of the metanotum very closely rugosely punctured. Median segment short, transverse at the apex, which has a rather sharply oblique slope and is impunctate between the furrows. Abdomen shining, sparsely punctured, the hair black, longish, and sparse ; pygidial area coarsely longitudinally rugose ; the ventral segment sparsely punc- tured on the apical half and bearing long black hairs. The third cubital cellule of nearly equal width throughout.

By Peter Cameron. [Connnuuicatcd by J. Cosmo Melvill, M.A., F.L.S.] Received November 9th. Read November 17th, 1S96. In view of the fact that Colonel C. T. Bingham is at present engaged on a Monograph of the Indian Hymenop- tera, I deem it advisable to give in this part of my paper descriptions of new species only, leaving the information I possess regarding the distribution and habits of the known species to be dealt with in another paper. Compared with the immense number of parasitic Hymenoptera (Ichneumonidse, Braconidse, &c.) known from the Nearctic and Palsearctic zoological regions they are but feebly represented, in fact the}' are almost absent in the southern parts of the Indian Peninsula; but they appear to be more numerous in Ceylon, and are probably not uncommon in the Himalayas.

Differs from all known Ichneumonidae by having only three visible abdominal segments, the third ending at the apex in a semicircle which forms at each side a stout tooth ; the scutellum projects at each side in a stout triangular tooth ; there are two large spines on the centre of the median segment at the side. Antennae 25-jointed. Legs and wings as in Ichneumon. This genus does not fit well into any of the subtribes of Ichncumonidcs. The alar neuration is quite as in Ichneumon ; but otherwise the genus differs completely ; and, as regards the abdomen, it can only be compared with some Braconidae such as Chelonus. The form of the spiracles I cannot determine from the roughness of the median segment. RoTHNEYiA Wroughtoni, sp. nov. (PI. 3, f. 3).

In some cases the smooth space is present without having horny points in it, or they are very faint. In either case I believe it will be found that the base of the cubital nervure is thickened, which is not the case with Ophion, scnsu^ str. In view of the great similarity of the species of Ophion, it seems to me desirable to adopt Enicospihis as a distinct genus. Species belonging to it are found in all parts of the world.

METHOCA. Smith described two Indian species of Methoca, under the same name — orientalis — (Cat. Hym. III., 66) from Northern India and another, renamed Smithii by Magretti {Ann. Mils. Civ. Genova, xxxii., p. 259), taken by Mr. Rothney at Barrackpore {Trans. Ent. Soc., 1875, p. 35). Both were described from males; and represent, so far as can be judged from the descriptions, different species. The undernoted female is, I should say, quite distinct from either. 52 Cameron, Hynncnoptera Oricntalia. V Methoca bicolor, sp. nov. (PI. 4, f. 12).

MUTILLIDiE. Since my paper on the Indian Mutillidse {Manchester Memoirs, V., 1892) was published, some additional species have come into my possession from Mr. Rothney and from Col. Yerbury. The collection from the last- named gentleman is of especial value, as it enables us to unite the sexes of a few species. The discovery by Mr. Rothney of an apterous 6 Mutilla, although not unique, is of interest. It is remarkable that the four known apterous species of 6 Mtitilla have the thorax emarginate, as it often is with 5 Mutillce, while it never is so in the winged males. a. Males.

The ? however has the thorax black, while in the typical M. soror 58 Cameron, Hyincnoptcva Ovicnialia. it is reddish ; but in other respects the two agree, except that the hinder femora have more black.
