Can't get this strange beetle to key out. Can anybody help? The head is very unusual to me. I've included a poor picture (sorry, I don't have the best equipment for these kinds of pictures). The head has large, fly-like eyes, and the penultimate segment of the labial palps, not the antennae, have the strangest comb-like extension (the 'folded' black structure in the fuzzy close-up picture of the head).
