DrPTEKA. 619 a perpendicular or incuned beak ; the palpi are curved under, or recurved, but in the latter case they have not more than two joints. Liniiceus united them in his genus TiPULA {Tipulari(B, Latr.), Which we divide in the following manner:— A first section is composed of species with antennae longer than the head, at least in the males, slender, filiform, or setaceous, more than 12-jointed in the majority, and with long and blender feet. Some, having always wings, are destitute of ocelli, the palpi always short, the head scarcely prolonged in front, the wings horizontal or roof-like, with but few nerves ; tlie eyes crescent-like, and the tibiae not spined. These are small species which reside, in the early states, either in water or in the galls of vegetables. The Tipulides Culiciformcs resemble Gnats, having the antennae entirely pilose, but with the hairs much longer in the males than in the females. Their larvae live in the water, and resemble those of Gnats. Some of them have false feet; others have arm-like appendages at the posterior extremity of the body ; they are generally of a red colour. The pupje are also aquatic, and respire by two outer appendages placed at the anterior extremity of the body. Some have the power of swimming. Corethra, Meg., has the antennae composed of fourteen oval joints, the terminal ones scarcely differing from the preceding', and the wings horizontal. T. culiciformis, De Geer [the Straw-coloured Midgej. Chironomus, Meig., has the wings inclined, the antennae 13-jointed in the males, and Gjointed in the females, with short hairs, the last joint, as in the males, being very long. T. annulata, De Geer, [a very numerous genus of Midges]. Tanypus, Meig., has the wings also deflexed, but the antennae are 14-jointed in both sexes; the penultira;te joint very long in the
