Agonum excavatum
based on my microscopic examination of this specimen which is now a photo-voucher in the P.W.Messer collection. Thanks Tom.

One diagnostic clue is the set of foveate (enlarged) punctures atop the elytra.

Moved from Ground Beetles.
It's saved for Peter, and one I don't recognize, especially being on the large end of the scale for a bemb.
