Head, antennae, legs, and prothorax piceous red. elytra and 

 pygidium ferruginous red ; head with a very long and sharp conical 

 tubercle ; antennal club thick, somewhat oval, carinate all round, 

 inner margin slightly sinuate, outer angle produced in a moderately 

 long, sharp, stout, slightly curving spine ; it is thicker in the middle, 

 and has four shallow striae extending on the upper part of the outer 

 declivity from about the median part towards the apex ; the club is 

 smooth in the basal part only, the rest is very briefly pubescent ; 

 prothorax divided in two by a broad transverse grooved impression ; 

 the anterior part is a little emarginate in the centre and truncate 

 behind, the posterior is as broad as the anterior, but a little less 

 abruptly truncate, and somewhat angulate laterally ; elytra sub- 

 parallel, shining, and with regular series of very short, slightly 

 flavescent, moderately closely set hairs ; tibia3 compressed, broad, 

 but not dilated. Length 11-11^ mm. ; width 4|— 4f mm.

 Piceous red, with the posterior part of the elytra from the median 

 part castaneous ; head with a sharp, long, conical spine ; antennal 

 club thick, but a little compressed in the basal part of the inner 

 declivity, marginate all along the inner apical part and slightly 

 sinuate near the apex, slightly incurved near the apical part, 

 which thus appears as if it were a little curved, posterior margin
