Habitat in India Orientali. Ncerauck, D. E. T. Downes. 
Corpus totum nitidum pare© pubescens, rufo-castanexim : caput antic© vix emarginatum, linea 
longitudinali vis impressa verticem fere attingente. Antennaruni clava prothoracis mag- 
nitudine margin© omni acuto ; externo vero prop© basin incision© lata et profunda dent© 
basali acuto. Prothorax capite pauUo latior, lateribus antic© rotundatis postice paullo 
angustior (sc. cordato-truncatus) impression© tenui transversa pone medium. Elytra 
tborace vix dimidio latiora angulis hnmeralibus prominentibus rotundatis, singulo cum 
tuberculo ordiuario ad angulum posticum externum instructo, rufo-castanea, singulo 
macula magna triangular! nigra versus medium suturam fere attingente. Abdomen apice 
nigro, subtus 4-articulatnm. Pedes castanei tibiis mediocriter dilatatis, apice oblique 
truncatis. 
This species was collected in the interior of India, at Neemuck, 
by Assistant-Surgeon E. T. Downes, who informs me that he 
caught a single specimen in his room by lamplight, having observed 
it crawling on his table. 
Species IV.— Platyrhopalus Acutidens. 
Syn. _ Platyrhopalus acutidens, “Westw. In Lin. Trans, xvi,, p. 661, pi. xxxiii., fig. 50. 
Ditto xix., p. 51. 
This species was proposed by me upon an incomplete specimen, 
preserved amongst the insects hx’ought from Nepaul by Maj.-Gen. 
Hardwicke, and now in the British Museum, of which the elytra, 
legs, and abdomen are wanting- The head and prothorax are 
smaller and darker-coloured than in P. denticornis ; the prothorax 
is proportionahly rather longer; the eyes are black ; the head 
rounded and subdepressed in front, and not emarginate; the inter¬ 
nal margin of the clava of the antenna exhibits a stronger contrac¬ 
tion at the base than in that species, and the incision on the outer 
edge is much wider ; and the basal tooth vei'y acute. In some of 
these respects it approaches P. angustus; but, until a more complete 
specimen is obtained, it is impossible to determine whether it"he 
identical therewith or not. The regular hind margin of the clava 
of the antenna, separates it from P. Westwoodii. 
Species V.— Platyrhopalus unicolor. (Plate 68, fig. 4.) (Copied from Sclionherr.) 
P. latus brunneo-castaneus, antenuarum clava magna ovata compressa juxta basin externo 
incisa ; dente obtuso, prothorace antic© utnnque rotundato dilatato. Long. corp. (see fig. 
Sebouberri), lin. 4J.
