Possibly a rove beetle species (Staphylinidae)? There are a couple dozen genera and several thousands of species of these guys, so you'd have to narrow it down based on your location first and then morphology. I don't think they're a common museum pest, but they do eat other insects and dead animals, so that would also depend based on your collection.

Hello all - I have some images of another insect I've never seen before. We've found two of them in the same room. The back of the abdomen looks oddly flattened, but it appears that way in both insects. I'd love to know what these are!
