" Shiny, black, nearly glabrous on the upper side ; sides of the 

 elytra, apex, and pygidium briefly greyish pubescent ; head simply 

 and finely punctate, that of the 2 rugose in front; clypeus produced, 

 reflexed and narrowed at apex, that of the $ truncate and hardly 

 sinuate, that of the $ deeply sinuate or bi-dentate, frontal part not 

 carinate, vertex depressed transversely between the eyes, but not on 

 each side, and bearing between the posterior part of the eyes a small 

 lamina, erect, truncate or sub-rounded at apex ; prothorax simply 

 and little densely punctate in the disk, but asperous in front and 

 towards the sides which are strongly sinuate behind, base mar- 

 ginate ; elytra broadly striate, intervals sub-convex, sparingly and 

 finely granulate towards the suture, more densely and also a little 

 more conspicuously so towards the sides ; pygidium moderately 

 densely and simply punctate.

Male: Black, moderately shiny, with extremely minute hairs in the 

 punctures of the head, prothorax and elytra; antennal club reddish 

 brown ; clypeus parabolic, but produced in the centre into a sub- 

 quadrate, strongly reflexed laminate process projecting far beyond 

 the margin, the genae are rounded, there are no traces of clypeal 

 suture, but in the frontal part there is a very slightly raised, short, 

 transverse fold interrupted in the centre, situated midway 

 between the eyes, and ending far from them, the greater part of the 

 clypeal area is transversely folded, and the rest of the surface, as 

 also of the frontal part, is deeply and closely punctate ; prothorax 

 broader than long, simple, without any basal fold, covered with 

 moderately deep punctures, slightly elongated and divided on the 

 median discoidal part by intervals about equal to their diameter, but 

 and more cicatrioose on the sides; elytra longer than the 

 prothorax, finely striate with the intervals plane, and having each 

 three or two series of fine punctures ; pygidium closely punctulate, 

 glabrous, broader than Long, and with a basal marginal fold ; inner
