MONOGRAPH OF THE COLEOPTEROUS FAMILY PAUSSID 43. 79 
Habitat in India Orientali. Neemuck, D. E. T. Downes. 
Corpus totum nitidum parce pubescens, rufo-castaneum : caput antice vix emarginatum, linea 
longitudinali vix impressa verticem fere attingente. _ Antennarum clava prothoracis mag- 
nitudine margine omni acuto ; externo vero prope basin incisione lata et profunda dente 
basali acuto. Prothorax capite paullo latior, lateribus antice rotundatis postice paullo 
angustior (sc. cordato-truncatus) impressione tenui transversa pone medium. Elytra 
thorace vix dimidio latiora angulis humeralibus prominentibus rotundatis, singulo cum 
tuberculo ordinario ad angulum posticum externum instructo, rufo-castanea, singulo 
macula magna triangulari 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. 
Sprcres [V.—Pratyruopatus AcuTIDENs. 
Syvn.—Platyrhopalus acutidens, Westw. In Lin. Trans. xvi., p. 661, pl. xxxiii., fig. 50. 
Ditto xix., p. 51. 
This species was proposed by me upon an incomplete specimen, 
preserved amongst the insects brought 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 proportionably 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 very 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 be 
identical therewith or not. The regular hind margin of the clava 
of the antenna, separates it from P. Westwoodii. 
Species V.—Pratyruopatus unicotor. (Plate 68, fig. 4.) (Copied from Schiénherr,) 
P. latus brunneo-castaneus, antennarum claya magna ovata compressa juxta basin externe 
incisa ; dente obtuso, prothorace antice utrinque rotundato dilatato. Long. corp. (see fig 
Schdnherri), lin. 43. .
