It looks like Anobium sp. to me. The Lyctus I've seen tend to have a thorax that is more narrow than their abdomen, whereas Anobium seems like their thorax and abdomen are pretty equal in width. Anobium also seems to have it head positioned lower, as if the thorax gives it a little neck shield. I found a site with a good explanation of identifying the differences between Lyctus sp. and Anobium sp. that you may find useful: http://ipm.ucanr.edu/PMG/PESTNOTES/pn7418.html Bugguide.net also has good pictures. For an artifact, I would approach a similar treatment for either -- anoxic chamber would be my first choice if you have that available; if not, then freeze treatment over heating treatment, which I would be concerned that you'd run the risk of over drying the wood and cause cracking. Then clean it really well with a HEPA vacuum and brushes.

We will be freezing the mask. The beetle pictured was found in the wrapping (it was found dead). I am wondering, can anyone confirm if this is a Powderpost beetle vs a Furniture beetle? In the end, does distinguishing between the 2 really matter? (treatment methods, severity of damage, one being considered "worse" than the other...) Thanks!
