Unknown Oklahoma beetle - Geopinus incrassatus

Unknown Oklahoma beetle - Geopinus incrassatus
Hinton, Caddo County, Oklahoma, USA
August 3, 2002
I can't figure out what family this beetle belongs to, let alone genus or species. Any ID help would be appreciated. It was crawling on the ground under a street light.

Geopinus incrassatus
This is a quite distinctive carabid (as far as carabids go). It is very pale in color and superficially almost scarab-like. Also, the front tibia are characteristically expanded into a plate-like process at the apex (tip). G. incrassatus is the only species of the genus, and is quite wide-ranging, from the east coast west to Idaho and Nevada.

My first post on the Guide, I hope it's up to par!

Ground beetle
This is a ground beetle, family Carabidae. I'd say it is one of the "seedcorn" beetles, Stenolophus sp., very abundant in the plains states. As the name implies, they feed on damaged corn and other grains, as well as prey on other insects.
