Thanks
This was in the backyard, so I could likely get more pics. What features would you need better pics of for a specific identification?

 
Hi Ben, Currently the dive
Hi Ben,

Currently the diversity of this genus is not completely known in northeastern North America, so species ID is impossible at the moment. I am working on a paper with a colleague to address this issue for the future, hopefully we will be done sometime this year,
Cheers,
Adam

neat antennae -- of the type shown in Callicerus
...on Fig.319(1) -- the book says, "one undescribed sp., Ontario, in groundhog burrow" -- so may be a member of one of related genera, of which i know squat...

Moved from Rove Beetles.
