beetle - Coniontis
Hayward Regional Shoreline, Hayward, Alameda County, California, USA
August 16, 2005
Size: 10 mm
This beetle has especially short antennae. Almost looks as if they were amputated (exactly the same amount on each side). That's how it looked when I found it walking across a dusty trail several yards from the San Francisco Bay.

Tenebrionidae.
I think you are right on the money with the diagnosis of amputated antennae. This is probably a tenebrionid, and probably in the genus Coniontis, which should occur in abundance down there.
