Bess Beetle - Odontotaenius disjunctus
Greenwood County, South Carolina, USA
November 2, 2005
Large beetle found under a dead log in my woods. I didn't get a measurement, but it was ~4cm long. There's a tiny bug of some sort on the left side of the beetle between the pronotum and the elytra that I only noticed while reviewing the photo.

Passalid
Looks like a Passalid of some sort. These are big beetles associated with rotting wood. The tiny bug was likely a mite:.
Perhaps this is the species?

I agree
I agree that this is the species; Nearctica.com seems to prefer the name Popilius disjunctus.

This family has only three species in two genera. Popilius disjunctus is one, and there are also two species in genus Passalus. The later genus is not represented in BugGuide yet.

Bess Beetle
I think you're right on the beetle. I'll move it there shortly if noone else comments.
