Thank you, William
Thanks for the identification....there were several locations under the bark of this particular tree where three or more of these beetles were hibernating...Do their larva feed on these trees? I was surprised that the adults varied in size as much as they did.

these are all Cibdelis blasch
these are all Cibdelis blaschkei, good find :)
