Illinois; Mr. Ulke. Much narrower than our other species, 

 and clothed with fine pubescence, not with erect hairs. The 

 disc of the thorax is fuscous, scarcely variegated, and the broadly 

 depressed sides are testaceous ; the elytra are variegated with 

 fuscous and testaceous, with the narrow lateral margin testa- 

 ceous ; there are some small scattered pale spots, and a large 

 common transverse dentated pale spot extending half way from 

 the margin across the suture and a little behind the middle. The 

 head and antennae are fuscous, the under surface rufo-testaceous.

York County, Pennsylvania ; Dr. Melsheimer. Broader than 

 P. histrina ; apart from color it differs by the thorax being uni-
