Many species in the northwest
Many species in the northwest..need to scope to see things like microsculpture, etc..if you have Lindroth on hand, try running it through the key.

Bembidiini?
a large Elaphropus-like thing? The palps look bembidiine-like (at least in these images)

haha
You're right, the palps at this angle look exactly like Bembidion, but the last two segments are equal. I'm using a different scope now and realized there's a setigerous puncture in the scrobe. I need to use this scope more often.
