Hard part?
It's all hard to me. Thanks Boris and Tim for a wonderful job of teamwork!

Thanks Boris

genus Cerylon
:-)

 
C. unicolor
Downie and Arnett, and UNH database, list only two Cerylon for our area. As the pronotum sides are nearly parallel (except for apex) and the elytra intervals are convex vice flat, this is Cerylon unicolor (Ziegler), as are all the other Cerylon from Jim currently pictured in BugGuide.

As usual, Boris did the hard part. The rest was easy :)

 
hard part?
No, it wasn´t hard at all. Fairly easy genus to recognize, this one . . .
For me, the species ID would be hard, not having easy access to N-American literature sources.
