Calosoma protractum
based on my microscopic examination of this male specimen. Known range is AZ, CO. Type image here. Note characteristic fine uniform punctures along barely visible striae on elytra; evenly rounded pronotum. I measured apparent body length to be 24.5 mm which is diagnostically important (in part) for separating similar but larger C. macrum known in AR, LA, TX.
