Yes, Cucujus.
I should have told you what it was that shed its skin :-) The urogomphi or tail spines are in the Cucujus configuration. See flat larva urogomphi compared here, here, and here.

Pyrochroid?
Cucujus is one possibility, that family another. Pyrochroid larvae are similar, and also found below bark.
