Kev. ZooL, 1866, p. 73. 



Head with a greyish tomentum ; prothorax cordiform, closely 

 punctured, broadly grooved in the centre, with a longitudinal pubes- 

 cent white band ; elytra oblong, depressed in the anterior part, more 

 plane behind, each one with eight sharp costae reaching from the 

 base to a short distance of the apex, intervals with small alveolae, a 

 sutural white band reaching from the base to the apex, and merging 

 there in a white pubescence covering the latter part. Length 

 23 mm. 



The only examples of that species I have seen are in De Chaudoir's 

 collection.
