. The animal kingdom, arranged after its organization, forming a natural history of animals, and an introduction to comparative anatomy. Zoology. 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 thev are entirely horny, and toothed : the tonguelet consists of two small hairy setae 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 ; maxillae 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 antennae 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. Scarabccus ci/lindiicus, Linn., a common British insect. Those with the body convex, ovoid, and the mandibles elevated vertically, and shorter than the head, form two subgenera,— Aisalus, Fab. (having the body short and convex, the mandibles terminated above in a horn, and the maxilla; covered by the mentum, composed of a single European species, /~Es. scarab<eoides, Fabr.), and Lamprima, Latr. [composed of splendid metallic Australian insects, Lethrus tcneus, Fabr., &c], with the body more elongated, the mandibles much longer than the head in the males, and very much toothe
