Black beetle - Carabus nemoralis

Black beetle - Carabus nemoralis
Salt Lake City, Salt Lake County, Utah, USA
May 25, 2009
Size: 1 inch
I posted a European Ground Beetle before, if this is what this is, but my question is why doesn't the elytra of this insect fit the body? Is it in the "family way" and nothing fits?

Gravid female
It certainly appears to to Carabus nemoralis, and the reason that the elytra do not seem to 'fit' the body is that this is likely a gravid female, and her abdomen is distended with eggs.

Yes,
this appears to be Carabus nemoralis. I'm unaware of any reports of occurence in UT. It is known in adjacent states ID, NV, WY according to the catalogue by Bousquet & Larohelle (1993). The data are worth saving at BuGuide.
