Moved from Prionus.

Prionus californicus
This species is common and widespread across the western U.S. While P. heroicus has been recorded from California, it is encountered primarily in Arizona and New Mexico. Prionus heroicus is distinguished from P. californicus by its very broad prothorax (almost as broad as the base of the elytra) and its darker, not reddish coloration. Also, the male antennae of P. heroicus do not show the pronounced external projections as seen in this male P. californicus.

Thanks, Ted
I guess i have a chance to find P. heroicus then here in AZ

Moved from Prionus.
