Darkling Beetle? - Carabus nemoralis

Darkling Beetle? - Carabus nemoralis
Salt Lake City, Salt Lake County, Utah, USA
July 8, 2007
Size: 1 inch
I found this beetle dead in my garden. I don't know if the purple cast came after death or was part of its natural coloring. The antennae segments seem to get longer the further they go out from the head. Can anyone narrow this one down?

i'm sure it's nemoralis indeed
Moved from Carabus.

Carabus nemoralis

cf Carabus taedatus
While Ray Simpson's comparison image certainly fits Carabus nemoralis, the original one from Utah best fits closely related Carabus taedatus in my opinion based on non-metallic elytra vs bronzed in nemoralis, suggestion that elytral striae are more regularly linear vs irregular scale-like in nemoralis, known in Utah vs nemoralis not reported there.

Quick ID...
Thanks for finding that so quickly. Your time is appreciated
