 convex, coarsely and rather sparsely punctate, humeral angles obtusely 

 rounded, basal margin feebly sinuate. Scutellum coarsely, sparsely 

 punctate. Elytra evenly, rather thickly and coarsely punctate. Length,

Occurs throughout Indiana but apparently scarce. Found 

 throughout the year. Two specimens were taken in Vigo Co., 

 Feb. 23, 1893, from beneath the close fitting bark of a black 

 oak (Quercus velutina Lam.) log which lay on the side of a high 

 sandy hill near the Wabash River. Eight others were taken 

 Oct- 13, 1899, from beneath the bark of a gray pine, Pinus di- 

 varicata (Ait.) on the top of a high sand dune near Millers, Lake 

 Co., Ind. It is therefore seen to be gregarious while hibernat- 

 ing. In summer it has been taken singly or in pairs in Marion 

 and Knox counties, by sweeping along the margins of ponds 

 and marshes. Ranges from New York west to Minnesota, Mon- 

 tana and California. Not recorded in the east south of Mary- 

 land except by Reuter from 'Texas and Carolina." That author 

 founded for histrio (loc. cit.) the genus Callicapsus which he
