The ochraceous-ashy fascia at the commencement of the posterior declivity of the 
elytra is straight and unusually well defined, contrasting strongly with the uniform 
purple-brown colour of the rest of the surface. In a natural position of the legs the 
colour of the fascia is seen to be continued to the inner side of the femora. The 
tubercles of the elytra are not pointed or much elevated, nor are they furnished at their 
summits with fascicles of bristles, as usual in the genus.

sed minus elongatus, fulvo-fuscus, thorace subcinereo, elytris interdum hic illic viridi-eeneo-tinctis ; thorace
