It is timid andFig. 397. slow in its movements, and when, disturbed seeks ashelter, or mimics death. We have found the larva () of probably another species of Dermestes, crawling upthe side of an out-house. It was nearly twice the size ofD. lardarius. Attagenus peUio Stephens is another insectwhich infests museums. It is shorter than Dermestes, black,with two dots on the wing covers. The larva (Fig. 397, en-larged three times) is long and slender, cylindrical, with red-dish brown hairs closely appressed to the body, giving it asilky, shining appearance. The abdomen ends in a long pen-cil of hairs. It has been known to eat holes in carpets. Anthrenus varius Fabr. (Fig. 398 ; a, larva; b, pupa) Isrounded oval, with transverse waved lines. Its larva is thick,. GEORYSSID^. 449 with long bristles, which are largest on the end of the are generally destructive in museums, and prey on stuffedspecimens of all sorts. The beetles fly about early in springand then lay their eggs. The insect is found in all its stagesthiough the j^ear. They may be killed like the Clothes-moth,also found in museums, by saturating the specimen infestedby them with benzine. To pre-vent their attacks, they shouldbe kept out of collections bykeeping benzine in constantevaporation in open and turpentine andcreosote are also very recently prepared should Fig. 398. be placed in quarantine, so we may be sure none of the mu-seum pests will be introduced into the drawers or cases of thecabinet while either in the egg or larva state. Their presencein cabinets may be detected by the dust they
