From what i gathered from your site, this appears to be a Broad Necked Root Borer? I guess that would make sense since it crawled out of my lawn. Have to say its strength was impressive as it powered its way back into my thick tall fescue.

California Prionus

Hi redfive,
The Broadnecked Root Borer is an eastern species.  This is a California relative, the California Prionus, and it is a male judging by his impressive antennae.  It is a little late in the season for a sighting, so we are speculating that this image is from your archive.

Daniel,
Yes, this is from my archive, but still not too long ago. August 7 of this year to be exact.  Thanks and I’ve enjoyed your website for awhile. Keep up the great work!
