. Cuvier's animal kingdom : arranged according to its organization. Animals. COLEOPTERA. 529 mandibles are always horny, often very much porrected, largest, and very diversified in form in the males. The maxillae are commonly terminated by a long, narrow, hairy lobe, but in some they are entirely horny, and toothed ; the tonguelet consists of two small hairy setse extending beyond the large horny mentum ; the fore-legs are often elongated, with the tibiae externally denticulated ; the tarsi are terminated by two equal and simple claws, with a small appendage between them, terminated by two bristles ; the elytra entirely cover the body. We divide them into two sections, the first of which has the antennae strongly elbowed, naked ; labrum very small, united to the clypeus ; maxilla; terminated by a membranous or coriaceous lobe, very hairy like a pencil, without teeth, or with only one ; the tonguelet either entirely concealed, or incorpo- rated with the mentum, or divided into two narrow, long, hairy lobes : this section forms the genus LUCANUS. Those which have only three or four joints in the club of the antenuœ form a first division. Sinodendron, Fab., has a strong resemblance to Oryctes: the body nearly cylindrical, the mandibles hidden, without teeth, and alike in both sexes; the head of the males has an erect horn. ScarabauscyUndricus, Linn., a common British insect. Those with the body convex, ovoid, and the mandibles elevated vertically, and shorter than the head, form two subgenera,— ^salui, Fab. (having the body short and convex, the mandibles terminated above in a horn, and the maxillae covered by the mentum, composed of a single European specie», ^s. scarabieoides, Fabr.), and Lamprima, Latr. [composed of splendid metallic Australian insects, Lethrus ceneus, Fabr., &c.], with the body more elongated, the mandibles much longer than the head in the males, and very much toothed and hairy within. Those with the body flatter, especially in the females,
