The body is shorter than in the following: genus, with the thorax broader than long. One of the sexes has in some species a hook at the tip of the elytra ; the basal joint of the antenna; is often dilated and irre- gular-shaped in the males ; their colours are agreeable. [These are active, pretty little insects, found in the spring and summer months, especially frequenting umbelliferous plants to prey upon the weaker insects which inhabit those flowers.] Types, Caiilharis ccnea,l,\nn., &nd Caiit/iaris bipmtulata, Linn, [two very common British species]. Dasyfes, Fabr., has filiform palpi ; the thorax is not furnished with vesicles ; the antennae at least as long as the head and thorax,and the body generally narrow, and sometimes linear. D. aerideus, Fabr. Zyffia, Fabr., and Meli/ris proper are composed of exotic species, having the ungues unidentate; the antennas shorter than the head and thorax, and the body shorter and of a more solid consistence. Pelecophorus, Dejean, has the maxillary palpi terminated by a large hatchet-shaped joint. NofoAriis lUiçieri, Sch. Diglobicerus, Latr., has the antennas only distinctly 10-jointed, the last two joints being large and globular. The fourth tribe of the Malacodermi, that of the Clerii, so named from the typical genus Clerus, is distingiiished by the following characters :—Two of the palpi at least are advanced, and terminated in a mass ; the mandibles are dentate ; the penultimate joint of the tarsi bilobed, and the first very sliort, or indistinct in many species ; the antennae are either filifo
