 obliquely sloped towards the posterior angles which are obtuse 

 but rather elevated, disk convex, smooth and shining, the dorsal 

 furrow terminating in front in a triangular impressed space, the 

 base depressed and with a fovea near each angle. Elytra rather 

 straight in front, with the humeral angles obtuse but not narrowed, 

 sides almost parallel, disk depressed, livid testaceous, w r ith the 

 scutellum and a triangular patch at the base of the suture fuscous,
