Trogoderma, Latr., has the club of the antennœ lax, 4-jointed, and the body oblong. Anthrenus elongatus, Fab. Anthrenus, GcolT., has the antennae terminated in a solid obconical mass, lodged in short cavities beneath the fore angles of the thorax. The species of this genus are very small, living upon flowers in the perfect state, but feeding in the larva state on dried animal matters, especially preserved collections of insects. Tliese larvae are oval, clothed with hairs, which are sometimes denticulated, forming brushes, the posterior ones being elono-ated behind like a tail. The last skin of the larva; serves as a cocoon for the pupa. Byrrhus verhasci, Linn. Globicortm, Latr., has the antennae terminated by a solid globular mass. Megatoma rufitarsis, Latr. The eighth tribe, Birrhii, differs from the preceding in having the feet entirely contractile, the tibiaî folding upon the femora, and the tarsi upon the tibiae, so that when these limbs are thus contracted and closely applied to the body, the animal seems absolutely destitute of feet and lifeless ; the tibiîe are ordinarily broad and compressed, the body is short and convex. This tribe is composed of the genus Byrrhus, Linn. Nosodendron, Latr., differs from the rest in having the mentum entirely exposed, wide, large, and shield-like, the antenna; suddenly terminated in a short 3-jointed mass. The species are found under the bark of trees. Byrrhus proper, differs in having the mentum of the ordinary size. In some the antenna; increase gradually, or terminate in an elongated 5 or 6-jointed mass. S.^(7«
