Yes, it's Harpalus pensylvanicus.
Do you know the collection date?

Yes
The specimen is at work though. I will fill in the collection details tomorrow.
Thank you so much for the ID. For some reason I kept coming to Notiobia (Anisotarsus) in the key I was using (Lindroth, 1961). I’m sure I was just misinterpreting a feature.
I should probably get my hands on a newer reference for Carabidae. Bousquet (2010) looks like a great reference for my area. Anything else you can recommend?

Well illustrated in Bousquet (2010):
Hind tarsus with first tarsomere distinctly longer than longest apical spur of metatibia. Male front tarsi underneath with spongy adhesive setae. --> on the way to
Notiobia
.
Hind tarsus with first tarsomere not or slightly longer than longest apical spur of metatibia. Male front tarsi underneath with seriate adhesive setae. --> on the way to
Harpalus
.
Imaged here is a female so genus separation is not so obvious.
In this case, the absence of any setigerous punctures in the vicinity of elytral interval #3 lends support to subgenus
Harpalus (Pseudoophonus)
and eliminates genus
Notiobia
.

I gotta get a copy
Looks pretty hard to come by. Used copies on Amazon are pretty pricey. Any other ideas where to get a copy?

Options to acquire Bousquet (2010)
(1) Amazon.com: best price for new copy $198, beats used copies.
(2) Bookfinder.com: best price for new copy $155 (includes shipping) via AbeBooks, beats used copies.
(3) Personally photocopy the book held in a university/entomology library or, if possible, borrow it via your interlibrary loan system. I know of one grad student who used a university photocopier machine to convert blocks of pages by taxonomic sections into PDF files. If you're only interested in adults, the large larvae section can be skipped. Photographs (B&W and color plates) were captured well by the PDF files. I believe the entire copying process was free as long as everything was saved to a personal USB storage devise inserted into the machine.
