Carabinae? - Scaphinotus elevatus

Size: ~35mm
Found in flower bed. Thought it might be a Scaphinotus, but I'm not even sure of the subfamily.

Scaphinotus elevatus
This looks more like Scaphinotus elevatus to me. Unicolor is big like viduus (up to 30 mm) but has a square, rather than narrow pronotum. I remember looking at a big series of unicolor at the Univ. Maryland collection and I think they were all dull black without a lot of iridescence. Also, the posterior pronotal margins not so reflexed. So I think this is more likely elevatus. BUT, that beetle doesn't get bigger than 20 mm. Are we sure the size measurement is accurate?

 
thanks a lot for the input, Frank
i'll ask around -- esp. those in MO

Peter Messer told me offline 5/24 that "Given the huge size... is likely an overestimate, I am forced to favor S. unicolor (at 85% confidence level today)"

 
Overestimate entirely likely
Not measured in field, estimated from memory

 
I have to agree with Frank. I
I have to agree with Frank. I've caught S. elevatus near Nevada, MO that look like this. Beautiful beetle!

 
Yes, "Scaphinotus elevatus flammeus",
a subspecies west of the eastern nominate form, based in part on the apparent green-blue iridescence of elytra not seen in S. unicolor. The reported body length "35 mm" is a gross overestimate.
