DESCRIPTION. 



Body oblong, depressed, black, rather glossy. Head lightly, neck confluently, punctured; nose 

 not distinct from the front ; knob of the antennae cinereous : prothorax nearly circular, anteriorly 

 emarginate, slightly punctured in the disk, more thickly at the base and sides ; a long basilar impres- 

 sion, or furrow on each side : elytra thickly punctured, with three longitudinal ridges ; towards the 

 apex, between the second and third, is a tumour, and after that an abbreviated orange band formed 

 of three spots, that nearest the suture not touching the others. 



The posterior thighs of the male of this species are not much more incrassated than those of 

 the female, but on each side of the knee-pan, or cavity that receives the head of the tibia, is a 

 minute tooth.
