. Cuvier's animal kingdom : arranged according to its organization. Animals. NEUROPTERA. 577 THE SECOND FAMILY OF THE NEUROPTERA,— The Planipennes,— Which composes, with the following, the greater portion of the order Synistata of Fabrioius, com- prises those Neuroptera which have the antennae always composed of a great number of joints, and longer than the head ; the mandibles are distinct, and the lower wings nearly equal to the upper, extended, or simply folded under at the inner edge. They have generally the wings very much reticulated and naked, with the maxillary palpi ordinarily filiform, or rather thickened at the tips, shorter than the head, and composed of four or five joints. I shall divide this family into five sections, composing, on account of their habits, so many small distinct sub-families. 1. The Panorpaltp of Latreille, which have five joints in all the tarsi, and the anterior extremity of the head prolonged, and narrowed in the form of a beak or rostrum. They constitute the genus Panorpa, Linnajus,— And have the antennae setaceous, and inserted between the eyes ; the clypeus prolonged into a corneous conical plate, grooved beneath to receive the mouth ; the mandibles, maxillae, and lower lip nearly Unear ; four or six short filiform palpi ; those of the maxilla; appearing to me to consist of only four joints. The body is long, the head vertical, the first segment of the thorax very small and collar- like. The two sexes differ greatly in many species. Their transformations have not been observed. Nemoptera, Latr., Oliv., has the hind-wings exceedingly long and linear, and the ocelli are wanting. These singular insects have hitherto been only observed iivthe hottest parts of Europe, Africa, and the adjacent parts of Asia. [See the recent monograph of Klug in the Berlin Transactions.^ Bittaeus, Latr., has the four wings of equal size, as well as ocelli ; the abdomen is alike in both sexes, and the legs long and terminated by a single tarsal un
