Ranges from New England west to Illinois. Uhler says it 

 is : "Common in the Coastal region and in shallow pools, heated 

 by the sun's rays, these insects are cooked of a red color."

Raleigh, N. Car., Nov. 17 (Brimley) . Recorded only from 

 Rhode Island, Massachusetts and Connecticut. The strongly 

 rastrate pronotum with narrow vague lineations, the arrange- 

 ment of black hues on the elytra and the fewer pegs distinguish 

 this from its allies.

 ground with narrow flecks of a paler hue. Frontal depression shallow, 

 not reaching middle of eyes. Pala as in key. Length, 8.5 mm. 



Recorded only from Maine and Massachusetts.
