I found this dead in my New Mexico garden. I've never seen one like this alive, and would love to know what it is. Please forgive the hairs and other stuff I never noticed until I looked at the photos! This is a good sized beetle at 46 mm. The color is pretty much silvery gray with black spots and splotches.

How big is it? Maybe a female Dynastes granti?

That does look like it, Sue. Thank you! Apparently it is Dynastes grantii. Some mis-spelling going on in the web.

I thought that too, the spelling does look wrong, but according to the Catalogue of Life Dynastes granti is the correct accepted name:

What a beauty. Found this discussion on i vs. ii on Bugguide.

Thanks, Sue & Leslieray. @GregC. Any input on this one?

Probably Dynastes granti, Dynastes tityus would be more eastern in distribution

Thank you all for the help! I appreciate it.
