Carabidae: Calosoma? - Calosoma calidum

Carabidae: Calosoma? - Calosoma calidum
Turtle River State Park, Grand Forks County, North Dakota, USA
June 14, 2011
Size: Length ~ 2.5 cm
Could this specimen be C. scrutator or C. calidium (are those gold spots on the elytra?). Caterpillars gallore in the oak-linden-ash forest where found, and my left thumb and index finger did stink after handling the specimen to get a close-up shot. Hoping for help with the species identification, if possible. Thanks! ;-)

male calidus [one 'i']
Moved from Beetles.

 
Thanks, v belov!
Great! That's a new beetle for me. And I note that Callisthenes is a genus that does not appear in any one of my four insect books! Callisthenes replaces Galosoma now? Hmmm...I reckon it's time to get better, more recent book on beetles! Thanks for you help with this beetle!

 
Calosoma frigidum?
Not so sure. This might be Calosoma frigidum instead?
