of the elytra are densely punctured, the first costa extends from the tip nearly to the base; 
the second commences at the middle of the base and reaches nearly to the tip; it is broadly

slightly sinuate, behind the middle; the third costa is interrupted only by the posterior 
impression, immediately behind which it unites with the second.

Lake Superior to Georgia: abundant. Readily known by the flat body, suleate thorax 
and dark colour of the upper surface. 
The last ventral segment in this and the next species is triangular, the sides nearly 
straight, with a submarginal groove, inside of which the surface is simply convex, with- 
out any distinct elevated line. The abdominal segments do not. project strongly on the sides.

and a female in which it is coppery, with purple spots at the sides of the abdomen. The 
sides of the thorax are sometimes straight, sometimes rounded, but it is never obviously 
wider in front.
