formincr a parallel lobe truncate but with both the angles slightly 

 rounded and projecting a good distance beyond the eye ; this lobe is 

 roughly punctured, and the bi-impressed posterior part of the head has 

 also^ a few rugose punctures ; prothorax very diagonally attenuate 

 laterally in front, hardly ampliate towards the median part, and 

 slightly sinuose above the posterior angle which is sharp, marginate 

 alH-ound, obliquely truncate in front where there is a moderately deep 

 but somewhat broad excavation with a slightly overhanging ridge, 

 emarginate in the centre and with the angles of the excavation sub- 

 dentate, posterior part sloping towards the sides, and covered on the 

 slope with somewhat deep, round, remote punctures, the median 

 part of the disk is nearly smooth, and the supra-marginal lateral part 

 is feebly punctate, but the excavation is smooth ; scutellum smooth, 

 faintly impressed longitudinally at tip ; elytra not broader than the 

 prothorax at the base, distinctly sinuate laterally and a little ampliate 

 from the median to the posterior rounded part, moderately convex, 

 callose on each side behind, and having, besides the juxta-sutural 

 stria, three somewhat distinct dupHcate rows of round punctures, the 

 intei^als also have series of similar punctures which on the sides 

 become most irregular and are somewhat closely set: pygidium 

 obsoletely shagreened, and with a faint longitudinal median impres- 

 sion reaching from base to apex; abdominal segments impunctate and 

 glabrous, sternum densely villose. The genital armature differs very 

 much from that of the other South African species. 



Female unknown.

 Head and legs piceous red; prothorax, elytra, and under side chest- 

 nut-brown ; not quite so robust as the preceding species, more 

 elongate, and with the elytra planer; the head is very hairy m 

 the centre, the clypeus is very narrow and m the shape of an 

 aculeate tooth recurved at tip, the cephalic horn is villose laterally 

 and varies much in length, the gense, which project beyond the eyes, 

 are moderately broad, oblique in front, diagonally truncate laterally 

 in the male, but with the upper angle sharp and recurved m the 

 female in which sex there is no cephahc horn but a very high trans- 

 verse ied-e aculeate at middle and connected by a longitudinal
