In color this species is usually greenish bronze. The surface is 
more or less alutaceo-granulate with elevated smooth spaces.

and the color varies from bronze to nearly black. The elevated smooth 
spaces of the elytra vary in number and extent.

B. punctatostriatum Say. —Trans. Am. Phil. Soc. 1823, II, 
p. 83. 
The color is bronzed. The surface is more shining than in the last 
three species, and, as a consequence, the elevated smooth spaces of the 
elytra are feeble or nearly obsolete. The quadrate foveae on the third 
interval are also less marked. 
Habitat: From the Atlantic to the Pacific, extending as far south 
as Arkansas.
