Economic entomology for the farmer Economic entomology for the farmer and the fruit grower, and for use as a text-book in agricultural schools and colleges; economicentomol00smit Year: 1906 THE INSECT WORLD. 179 for much mischief in tanneries and factories producing leather goods. Where fumigation is possible, bisulphide of carbon may be employed with good effect, while gasoline readily destroys both beetles and larvae where it can be brought into contact with them. Larvae similar to those above described, but much smaller, are often found in museum collections on mounted animals, eating the skins, hair, and feathers, and in entomological collections, destroying the specimens entirely. The beetles from these larvae are smaller and more ovate, and belong to the genera Trogodcnna or Megatoma. They are often found on flowers Fig. 158. The carpet-beetle, AnUwenus scrophtilaria.—a, larva; b, larval skin split to expose the pupa within it; c, pupa; d, beetle. in this stage, in company with species of Anthrcnus, in which the larvae are stouter, more clumsy, equally clothed with hairs, but with the ability to expand two larger tufts posteriorly. Ajithrenus also contains museum pests as well as the 'carpet- beetle,' A. scropliularia, which feeds on woollens in the larval condition, and is then better known as the ' buffalo-moth,' from its tufted appearance. The beetles are very broadly oval, with brick-red scales along the middle of the wing-covers, and two irregular white scaly bands transversely across the elytra. I have found them very early in sj)ring under the loose bark of trees where they had passed the winter. Later they fly into open windows, and lay their eggs wherever they And a supply of
