Labrum transverse or arcuate, not incised ; anterior coxae strongly oblique and vertical at apex ; clypeus either very short in both sexes or strongly prolonged and even bi-lobate in the male. The shape of the labrum and of the anterior coxae characterise this group which is represented in South Africa by five species, belonging to one or possibly two genera, the males of which have the two or three basal tarsal joints dilated and hairy underneath ; this dilatation can also be traced in the female of some species.

Body moderately convex or plane above ; labrum hidden under the clypeus; ligula fused with the mentum ; maxillae robust or slender, but not as massive or as robustly dentate as in the Melolonthini, except in the genus Diplognatha, and provided with an inner corneous lamina or inner lobe, and surmounted by an upper lobe varying in size and Bhape ; antennae 10-jointed, antennal club tri-jointed ; elytra leaving the margin of the propy- gidium and the pygidium uncovered, and also the edge of the dorsal part of the three abdominal segments ; mesothoracic epimera always greatly developed, vertical or strongly bulging; anterior coxae vertical ; abdominal segments seemingly ankylosed but with the sutures plainly distinct; claws of tarsi strong, simple, of equal length; hind tarsi with two long spurs at the inner angle. The affinities of the Cetonin.k lie in two directions. Certain Trichini and Myodermini connect this Sub-Family with the Melo- lonthin-E ; the Cetonini seem to be more closely allied to the Dynastin^:. From the latter they are divided by the shape of the mentum, and that of the mandibles, whereas these two parts are nearly akin to those of the Melolonthini ; in many species the lower spur of the hind tibiae of the female is often greatly dilated, and even spatuliform, also in the manner of many Melolontliini, and when of normal shape it is always blunter than that of the male. The mode of flight is unique among the Coleoptera, the wing-covers being merely raised vertically while the wings protrude underneath. Although the majority of these insects are living in the imago state on the pollen of flowers, the juice, sap, or gum exuding from many plants, many are termitobious or mvrmecobious ; others are coprophagous, some of them live in the larval state in the nests of birds, feeding on the excrements of the young, and making there their cocoon of stercorarious matter. The Sub-Family is divided into five sections, based on the shape of the scutellum and of the mesothoracic epimera. A . Scutellum short, cordiform, not acuminate at tip. B . Mesothoracic epimera invisible if looked at from above. . Tpichiini. B'. Mesothoracic epimera vertical, laminiform, visible from above Myodermini. A1. Scutellum long, or very long, sharply acuminate at tip. B3. Mi isothoraoio epimera vertical, not visible from above .. Valgini. B'. Mesothoraoia epimera large, or very large, plainly visible from above Cetonini. 1907.] Catalogue of the Coleoptera of South Africa, 295 The number of species recorded from the South African area is 223 divided into 101 genera. This is a good example of how great the tendency is, nowadays, to divide the genera on the slightest plausible reasons ; for there are few Sub-Families among the Coleop- tera which are as closely related to each other as the Cetonin^: are. The multiplication of species on the flimsiest characters excels that of the genera. I have satisfied myself, by an examination of the male genital organs, that a great many of them cannot be considered as valid. The endemic genera number 33, distributed as follows : — Tkichiini, 4. Agcnius ; Stegopterus ; Brachagcenius ; Eriopel- tastes. Myodermini, 2. Elpidus, Xiphoscelidus. Cetononi (Cetonides) 15. Xiphoscelis; Bhinocceta ; Lipoclita ; Atrichelaphinis ; Goraqua ; Trichostctha ; Odontorrhina ; Ischnostoma ; Gariep ; Heteroclita ; Baceloma ; Mazoe ; Gnathocerida ; Amazula ; Atrichia. (Cremastochilides) 12. Macromima ; Phymatopteryx ; Anatochilus; Plagiochilus ; Proxenus ; Astoxenus ; Genu- chus; Trichoplus; Myrmecochila; Anatochilus; Scaptobius; Placodidus. Six of these genera will probably be met with outside the South African area. Tribe TKICHIINI In the insects included in this Tribe, the elytra are either convex or plane, the ligular part of the mentum is deeply and broadly scooped out, the labial palpi are inserted in the outer face of the mentum, the upper lobe of maxillae is elongated, simple, and bears a long pencil of hairs, and the inner lobe is not distinct, the clypeus is a little longer than the head, the antennal club is as long or much longer than the pedicel in the £ ; the basal angles of the prothorax are not rounded but are always angular, and even sharply so, and the median part is not arcuate ; the scutellum is cordiform and as broad as long ; the apical end of the hind tibiae does not end in three teeth or spines, and the spurs are long, the upper one is occasionally strongly compressed in the 5 (Stegopterus) ; the tarsi, especially the hind ones, are very long and slender, with the claws long ; the basal joint is longer than the second, and there is no mesosternal process, except in Stripsipher. The body is partly pubescent, or glabrous, the pubescence is not squamose. 296 Transactions South African Philosophical Society, [vol. xiii. The South African species are found on flowers. They fly with great rapidity. The livery of the female differs from that of the male in some species belonging to the genus Agenius. It is not known if the laiwae make for themselves a cocoon. The characters distinguishing this Tribe are constant, provided that the genus Polyplastus, which, however, has not been met with as yet in the South African area, be removed from it. It is a very abnormal form, having dentate maxillae, a quadrate mentum, a scutellum as sharp at apex as the Cetonini, the mesothoracic episterna are conspicuous, and the hind coxae project beyond the elytra. The facies is, however, that of a Trichiid, the outer angles of the prothorax are sharp, and the outer teeth of the fore tibiae are similar to those of Stripsipher. Key to the Genera. A2.

The species included in this genus are strictly South African. One species (T. fascicularis) ranges from Cape Town to Natal and the Transvaal, and will probably be found in the South African area wherever Protcea grow. The larvae of another species {T. capensis) are found under the base of the small mounds made by the white ant (Termcs latericius), and are commonly found there in company with the large grubs of the Dynastid Pseudocyphonistes comiculatus ; they both feed on the material the mound is made of. This is the only genus in the Sub-Family Cetonini known to me in which the humeral callus is continued as a supra-lateral costa. 360 Transactions South African Philosophical Society, [vol. xiii.

Like the type, but the elytra and pygidium are opaque, roseate brown with a short marginal white line along the humeral part, and a few white dots, they are sometimes sub-seriate, in the anterior dorsal part. This variety occurs in Natal (Durban, Maritzburg, Frere) ; Trans- vaal (Potchefstroom, Lydenburg, Pretoria). Var. natalis. Like the var. prunipennis, but in addition to the four longitudinal white bands of the prothorax there is occasionally a central median very short line or elongated spots, the elytra are opaque, dark bottle-green and splashed all over with white macules ; some examples have no traces of a central line on the prothorax, and are only sparingly splashed with white punctures. Burmeister described this variety as having been captured by Drege in Natal. My examples are from Victoria West and Dordrecht, in the Cape Colony. Length 21-25 mm. ; width 13-15 mm.

Clypeus glabrous, deeply punctulate, the punctures not closely set, frontal part clothed with a fairly long ashy-grey pubescence ; the prothorax is moderately closely punctulate, and the punctures, although hidden by the opaque indumentum, bear each a long greyish or whitish seta ; scutellum impunctate ; elytra with the humeral costa reaching to about the median part, and having also a dorsal one reaching slightly further down, this dorsal costa is oftener than not nearly obliterated, the intervals are tilled with numerous, shallow sub- seriaie punctures, all the dorsal ones of which bear a long erect greyish or whitish seta ; pygidium with a long greyish or whitish pubescence; pectus, edge of the dorsal part of abdomen, and also the sides of the ventral part clothed with a long greyish or greyish-white pubescence ; legs and under side shiny. The opaque indumentum, the white markings, especially those on the elytra, and the dorsal setae are very often partly rubbed off (T. oculata, hottentota, fusco-r libra).

This species closely approximates rubbed examples of T. capensis, but the genital armature of the male differs considerably in shape. The head and prothorax are black and shiny, the latter has a narrow median reddish band, often reduced to a triangular reddish patch above the base, and a non-interrupted narrow white band along the lateral margin, both head and prothorax are glabrous, and the latter is very distinctly punctate laterally ; scutellum black ; elytra bright sienna-brown with the suture, the humeral costa, and the hind callus infuscate, they are opaque, indistinctly punctulate, the humeral costa reaches to about the median part, but the posterior callus is elongated, the dorsal costa is almost obliterated in the posterior part, and there are a few setae in the first and second intervals ; the pygidium is pubescent and has four longitudinal flavescent- white macules, the pectus and sides of abdomen are clothed with a dense fulvous pubescence. In some examples the elytra have a narrow sub-flavescent marginal band in the rounded posterior part. Length 19-22 mm. ; width 101-12 mm. Hah.

The genus is restricted to the South-Western part of the Cape Colony. The two massive species included in this genus belong plainly, in spite of the conformation of the basal joint of the hind tarsi of the male, to the Goliathites. Westerman states that he has found 0. jiubescens under dry cow- dung. Both 0. pubescens and 0. hispida fly round such places where cattle congregate, very much in the manner of a Scarabaus searching its provender, but they have not been detected, to my knowledge, in either the fresh or the dry cow-dung.

Sub-Tribe CETONITES. In this Sub-Tribe are included all the Cetoninous insects, the facies of which is somewhat elongated, and usually plane or depressed above, and in which the elytra when striate have the striae simply punctate, or geminate without punctures and reaching from base to apex; the basal joint of hind tarsi is obtuse at apex or sub- nodose. While the first group of this section, the Ischnostomii, have very distinct characters separating them from the others, the Cerator- rhinii, Heterorrhinii, Uymnctii, Pachnodii, Elaphinii, Porphyronotii, and Diplognathii merge into one another in such a manner that it is impossible to define them except by purely arbitrary characters.

Female : Like the male. The head is red, except the basal part of the head which is black ; the lateral band of the prothorax is 388 Transactions South African Philosophical Society, [vol. xiii. narrower and the anterior lateral denuded patch is connected with the black discoidal part ; the punctures on the upper side are setigerous.

Male : Black, covered on the upper side of the head and cephalic horns as well as on the prothorax with a muddy grey tomentum with the exception of a moderately broad, median longitudinal velvety black band which reaches from apex to base, and a minute, round, supra-marginal spot of the same colour on each side of the prothorax ; the elytra are covered with a velvety black tomentum and have on each side a dorsal row of four round, orange fulvous patches, and a lateral one of five similar but slightly smaller ones ; under side black, pectus very sparingly hairy, legs black with the hind tibiae and tarsi red ; the tomentum hides entirely the sculpture of the upper side ; the clypeal horn varies much in size (4-8^ mm. in the curve), the bifid process being almost straight in the smaller development and strongly divaricating in the larger, but the two hamate teeth of the vertex and the supra-ocular raised process are equally strongly developed in all the examples that I have seen, irrespective of their size ; the lower margin of the pygidium is densely hairy, and the hind tibiae have a few hairs near the base, and are not dentate on the upper side. Female : Coloured like the male, but the head has no tomentum, and is black with a median longitudinal red band on the clypeus ; the median thoracic black band is broader than in the male, the pygidium is briefly pubescent, and the pubescence along the margin is as long as in the male.

Natal (Durban, Maritzburg, Lower Tugela) ; Transvaal (Potchefstroom, Barberton) ; Mozambique (Lourenco-Marquez, In- hambane) ; East Central Africa (Usambara, &c). In the South African examples the colouration is singularly constant, the lateral denuded macule of the prothorax being, however, almost obliterated in some females, but in examples from East Africa that spot develops into patches, and even in a supra-lateral band reaching from apex to base, and partly or com- pletely connected along the base with the median longitudinal one (Boileau, Bull. Soc. Ent. Fr., 1898, p. 217, c. fig. ; Kraatz, D. E. Z., 1896, p. 349).

Female : Head and clypeus simple, the latter with the angles moderately rounded, and both deeply and somewhat closely pitted ; the prothorax is much more deeply pitted than in the male, and the intervals between the punctures are aciculate ; the lateral punctures of the scutellum and the seriate rows of punctures on the elytra are much more distinct ; the outer face of the marginal part of the anterior femora is as densely ciliate as in the male, and the fore tibiae are sharply tri-dentate outwardly. In the examples from Natal the prothorax is occasionally dull dark green, and the elytra of a lighter straw-colour than in examples from the Northern Transvaal and Southern Ehodesia. Yet I have received from Manica specimens with brighter green thorax and light elytra, but among them were examples of the normal hue. It is a somewhat similar light-coloured variety from Damaraland that Kraatz described under the name of E. hereroensis. North of the South African limit (Mamboia, Usambara, &c.) the type form is replaced by the variety euthalia, Bat., which differs from it in the colour of the elytra being of a rufescent yellowish hue with a tinge of green, the suture is narrow and green, and the apical elytral patch is narrowly edged with green. The variety penetrates also in the South African area, as it has been recorded from Mel- setter in Southern Ehodesia, but the solitary example which I saw is still nearer to the light variety of the type form than to my 392 Transactions South African Philosophical Society, [vol. xiii. examples of cuthalia from Mamboia.

Natal (Durban, Tugela Eiver) ; Transvaal (Potchef stroom) ; Southern Rhodesia (Salisbury, Melsetter, Manica). Feed on Acacia gum, but is also found on the wounded branches of a species of Combretum ; has never been seen on flowers; about Durban it feeds on the gum of Albizzia fastigiata. The var. cuthalia is found on flowers of Protea (G. A. K. Marshall). Eudicella caemelita, Fairm., Bull. Soc. Ent. Fr., 1894, p. lxxxvi. Fairmaire has described, loc. cit., a species the habitat of which is unknown, but that he considers to be South African, and which, from the description, appears to be very closely allied to E. smithi. The upper side is chestnut-red, opaque ; the head and the anterior margin of the prothorax are clothed with a dense white-greyish pubescence; the suture of the elytra is vaguely infuscate, and each elytron has a very narrow marginal fuscous line which disappears before the apex ; the pygidium is fuscous with two testaceous macules. In the rnale— the only sex known — the clypeus is armed with a moderately strong and moderately elongate horn bare at the tip which is bifid, and the cephalic lateral horns are moderately short and little diverging. The main distinctive characters of this species would thus seem to be the pubescence on the head and clypeus, except the apex of the clypeal horn which is bare, and on the anterior margin of the prothorax, also the absence of dark patches on the elytra. I doubt, however, if this insect inhabits the South African area, except on its confines. Length 32 mm. Eudicella trimbni, Jans., Cist.

Male : Head punctulate ; clypeus impunctate, outer angles pro- duced each in a moderately long, almost vertical horn, and the centre of the anterior part into a curved horn, bifid at the top, but the bifid process is not divaricating much ; the length of that horn varies from 2 to 7 mm. in the large development, and the shape is very much like that of E. smithi, but the curve of the central clypeal horn is stronger ; prothorax and elytra finely acicu- late punctulate except for a series of punctures along the suture and the outer margin ; pygidium concolorous, finely aciculate ; under side very weakly punctulate on the pectus, each puncture briefly setigerous ; sternal process grooved from the base to the meso- sternal suture, and impunctate ; legs as in E. smithi, but with a plain, although small, tooth on the upper edge of the hind tibial. Female: Shape like the female of E. smithi; the head is not so deeply punctate, and the punctures on the sides of the prothorax are small, and not rugose, those on the elytra are similarly fine and not set more closely ; the under side is more deeply punctate than in the male. Length 28-38^- mm. ; width 15-19* mm. Hah. Natal (Tugela River, Karkloof). There seems to be no doubt that E. chloc, Raff., is identical with E. trimeni, and Raffray himself told me so when he was shown an example captured by A. F. Millar in Natal. The rarity of this insect in South Africa is probably due to it being a straggler from the north. Raffray captured his examples in the Bogos province of Abyssinia. Gen. NEPTUNIDES, J. Thorns., Bull.

The genus includes two species, one of which is a denizen of East and Central Africa, but it reaches also the South African area, and is so variable in colouring that no less than six varieties have been described. The other species is recorded from the Congo. The shape of the mentum greatly resembles that of Cozlorrhina, Burm., but the palps cavity is wider, and apart from the differences in the sexual characters of the males of both genera, that of the sternal process is sufficient to separate the two.

Female : Coloured like the $ , except that the simple clypeus is reddish on the sides and on the extremity only, and even sometimes nearly completely green, the whole head is somewhat coarsely punctate, and the punctuation of the prothorax, scutellum, and elytra is similar to that of the male, but slightly deeper ; the pygidium is more plainly plicate, and the pectus very deeply punctate and briefly pubescent. Bates has given a figure of C. quadrimaculata $ . In that figure the two median teeth of the head instead of being set close to each other are broadly separated, being almost equidistant from the centre of the occipital excavation and from the outer wall. In C. lorigera, Jans., these two teeth are contiguous and median ; they are also median and somewhat longer in the great development of C. homimani, but broadly emarginate with the angles of the emargination very remote, and thus approximating C. quadrimaculata in the minor development, which I take to be C. grandyi of the same author ; C. homimani has greener elytra than G. lorigera, with a distinct longitudinal deeper green band reaching from the humeral to the supra-apical callus. As for the numerous species described by Kolbe, Kraatz, himself, whom no one will take to be a "lumper," gives it as his view that C. glabrata, radei, f areata, ruficeps, poggei, and imitatrix are one species. I entirely agree with him with regard to furcata, ruficeps, and imitatrix, the authenticated examples of which are synonymous with lorigera, Jans., and this is corroborated by the genitalia of the 398 Transactions South African Philosophical Society, [vol. xiii. S which are absolutely similar in all those varieties, with those of hornimani. I have not, however, been able to obtain an assumed typical C. quadrimaculata, as figured by Bates, but if its genitalia differ, which I doubt, then C. lorigcra, Jans., would stand as the type form of all the varieties here mentioned.

This species differs from the typical Stephanorrhina (guttata; princeps, adelpha, &c.) in having concolorous elytra ; the shape of the head of the male is also very different owing to the absence of anterior clypeal vertical horns, and the presence of an horizontal frontal lamina instead of an erect T-shaped cephalic horn.

Bright green, with occasionally a faint yellowish tinge in the dorsal part of the elytra; this green hue is, however, apt to turn bluish ; antennas chestnut-brown ; head moderately closely punctate, the punctures deeper in the anterior part ; prothorax very little punctate in the central part where there is a median impunctate longitudinal space, more densely and also more deeply on the sides where the punctures are separated by a space equal to twice their own diameter, this punctuation is the same in either sex ; scutellum almost impunctate ; elytra non-costate, plainly denticulate at the apex of the suture, very faintly punctulate in the male but more distinctly so in the female, especially in the dorsal part where the fine punctures are seriate ; pygidium transversely strigillate in the female, but with transverse punctures in the male ; under side glabrous, except on the anterior coxae and also on the outer face of the mention ; the abdomen is almost impunctate, but the pectus is punctulate and the legs deeply punctate and plicate. This handsome species was first described from the Guinea Hinterland. It does not seem to have been met with in the South African area further south than Rhodesia, but it is said to occur also at Beira. It bears a great resemblance to E. thoreyi from the West Coast, and to E. latipes from West Central Africa, but the genital armature of the male is very different from that of these two species, as also from that of E. relucens. 1907.] Catalogue of the Coleoptera of South Africa. 401 Length 27-29 mm. ; width 13 mm.

Male : Head, prothorax, scutellum black, tibiae very dark red, almost piceous ; elytra green with a strong bluish tinge, under side and tibiae dark chestnut-red ; antennae piceous ; in the general build and outline this species closely resembles E. barthi, and were it not for the punctuation of the prothorax, and the great dissimilarity of the genital armature of the male, this very distinct species might be easily mistaken for a colour variety of the same. The prothorax, however, is most finely and closely shagreened except along the median longitudinal part, instead of being plainly punctate later- ally ; the finely alutaceous elytra have no traces of punctures, and the suture is distinctly black ; the sub-rufescent pygidium is closely and finely plicate longitudinally ; the hind tibiae are glabrous inwardly, the inner sinuate ridge is much more raised, and the space between it and the upper edge much more deeply grooved than in E. barthi. Female differs from the male merely in having the anterior tibiae tri-dentate outwardly, and the hind tibiae of normal shape. The sculpture is the same as in the male. Hab. Mozambique (Beira).

This genus differs from Gnathoccra in the shape of the sternal process which projects very little beyond the coxae and is there vertically truncate ; the body is very densely hairy on both the upper and lower sides ; the basal part of the prothorax is only moderately arcuate above the scutellum which is shorter, broader at the base and not furrowed in the centre ; the upper lobe of maxillae is edentate, but the bristles are so stiff as to resemble spines.

Greenish black on the upper side and either opaque or moderately shiny ; head with or without a yellow, lateral hand; prothorax with a broad yellow lateral band, a black spot in the anterior part, and with either three triangularly disposed yellow patches on the dis- coidal part or two only, or, oftener than not, entirely without ; scutellum with two lateral macules or not, elytra with a broad yellow border, a black humeral spot, and another apical one, this holder 1907.] Catalogue of the Coleoptera of South Africa. 437 emits past the median part a transverse yellow band stopping slightly short of the suture (flaviventris), and edging thus an elongate quadrate discoidal part which is either immaculate, or is marked with two yellow patches near the scutellary part ; this band is also often interrupted in the middle, in which case the black dorsal part bears on each side two juxta-sutural yellow patches; pygidium brownish purple and with six minute white spots ; under side either brownish red or black with a few yellowish macules, or bright yellow with the sides reddish, and a spot or a very short silvery band on the upper side of the abdomen and the epimera; clypeus closely aciculate, head sparingly punctate, the upper part is almost impunctate, except for a few faintly seriate punctures in the posterior part ; glabrous underneath except on the presternum ; the last abdominal segment is closely aciculate, the others have a few lateral punctures ; the sides of the pectus and legs are strigillate ; the horizontal sternal process is almost orbicular and without suture. This is the most protean of the South African Cetonids. The colour of the upper side changes from opaque velvety black to shiny olive-green ; that of the under side varies equally, and is dark brown or almost black and with very few yellow macules in the species with opaque upper side in which the transverse post-median transverse band is interrupted, and bright yellow except along the upper sides in those in which the transverse band is entire. P. flaviventris, Gory and Perch., is a variety in which the prothorax and scutellum are immaculate, the transverse band of the elytra complete and the discoidal background immaculate. I am of opinion that it is really the type form, and that P. sinuata is the variety. Kraatz has figured and described some 19 varietal forms (Deutsch. Entom. Zeitschr., 1885, p. 341, pi. v.). I could add to this number, but in all of them the genital clasps are absolutely alike. Length 21-24^ mm. ; width 12-15 mm. Hab.

Black ; upper side opaque ; prothorax with a broad yellow band along the anterior and lateral margins, the width of that band is 438 Transactions South African Philosophical Society, [vol. xiii. about one-fifth of the whole, and in the anterior part there is a small black spot, often obliterated ; scutellum black, elytra with a very broad yellow band invading the black background to such an extent that the latter is reduced to a quadrate dorsal patch more or less deeply incised on each side, prolonged for a short distance as a nar- row band along the suture, and coalescing there with a transverse or slightly arcuate patch as broad as the anterior one but of only half the length, in addition to these two discoidal patches there is a Lateral supra-marginal small black patch or spot situated past the median part ; the pygidium is black with a flavescent triangular patch at apex ; the under side is black and immaculate. Clypeus deeply emarginate in front, closely punctulate, frontal part deeply and numerously variolose punctate, punctures on the prothorax also numerous and deep ; those on the elytra plainly seriate punctate in shiny examples, less distinctly so in the opaque ones ; pectus and inner part of legs pubescent ; sternal process horizontal, ampliate rounded laterally but only moderately deeply arcuate in front.

The figure of P. arborcsecns, Vigors, does greatly agree with this insect, the only difference being the absence of the post-median, supra-lateral round black patch. Pachnoda bella, Kraatz, Deutsch. Entomol. Zeitschr., 1898, p. 16, pi. ii., fig. 10. picta {Phoxomcloides), Schoch., Schw., Ent. Ges., 1898, p. 109. Very closely allied to P. laticincta, but very shiny on the upper side instead of being opaque, the black markings are exactly similar, and the prothorax appears more deeply and more numerously punctate, owing perhaps to the absence of the opaque indumentum ; the pygidium is also flavo-rufescent in the centre. The genital clasps of the male, although of the same pattern as those of laticincta differ in being a little shorter and less slender in the anterior half. Length 12£-15£ mm. ; width 7-8 mm. Hab.

Head, clypeus, and prothorax deeply punctate, the punctures somewhat closely set ; the elytra have shallow punctures indistinct on the sides, seriate and fairly distinct in the dorsal part ; under side glabrous ; abdomen sparsely and finely punctate, pectus deeply punctate ; sternal process ampliate rounded laterally, somewhat bluntly rounded in front ; pygidium transversely striolate. The tooth of the upper maxillary lobe is plainly bifid, and the inner lobe is slenderly dentate. I cannot decide if P. tridcntata, Oliv., is identical with P. cor data, Drury, but I find that the South African species of the latter are, even the females, more elongated than the examples from Kumasi and Senegal, the pattern of the fusco-rufescent bands or patches seems to be less variable, the shape of the genital valves of the males are absolutely similar.

The sculpture of the upper side is similar to that of P. cordata, but the sides of the pectus are more villose, and the sternal process more rounded in front. The livery of this species closely approximates that of P. imjjrcssa, but in the latter, which is also differentiated by the shape of the sternal process, the green background has invaded the whole of the discoidal part of the prothorax, and also the scutellum.
