Primitive Bombardier Beetle - Metrius contractus

I moved it here for now...

Carabid
That pronotum suggests Ground Beetle to me, worth another look

 
Might be!
Yes, this reminds me of a kind of primitive bombardier beetle, Metrius contractus, which should occur in that locality.

 
I like it
Didn't have any particular genus in mind, just didn't say darkling beetle. Metrius certainly looks good - did a little reading and very odd carabid indeed.
