Bill Warner:
"not atrox, possibly aequalis or....? It is in a group that needs peckers checked, but I think there are only one or two in that group in CA. Most are in bird nests and are rare in collections."
Moved from Trox atrox.

not T. atrox
We have a series of Trox atrox identified by Vaurie in our museum and this, unfortunately, isn't it. Trox atrox has much longer setae at the pronotal margins and the elytral intervals have a "single row of equidistant setae in center"- this obviously as spaced patches of setae. I'll try to post a picture of T. atrox later today or tomorrow.

According to Vaurie's key (1955), this likely T. aequalis or T. affinis (depending on size), less likely T. fascifer or T. scaber. I've found these critters to be fiendishly difficult to pin down, but fun to work with...
cheers, z

The specimen as T atrox
was identified by a specialist from CA, I'll find his name to attach it.
