The tergum is black with a broad white band at the base as in the alHed spe- 

 cies, which, showing through the closed elytra, indicates the markings found 

 on the elytra of cinereus. Face obviously longer and more convex than in 

 cinereus, with the basal middle depressed, and the clypeus and lorse together 

 larger, the former much broader, more convex and more decurved and rounded 

 at apex. 



Distribution. The type material was taken at Effingham, Kansas.
