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, sulcate thorax 
and dark colour of the upper surface. 
1 he last ventral segment in this and the next species is triangular, the sides nearly 
stiaight, 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.

The colour beneath is somewhat variable. I have a male with the body entirely green, 
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.
