Stratiomyidae (Waffenfliegen). Stratiomys , L,, St. Odou- tomi/ia lujdrolctni L., Sarijus L. Sub-order 3. Nemocera (Tipulariae). Longhorns (fig. 478). Diptera of elongated form, with many-jointed, usually filiform, antennte, which in the males are sometimes tufted. They have long slender legs, and large, naked or hairy wings. The palps are usually of considerable length, and with four or five joints. The proboscis is short and fleshy, and often armed with piercing setae. The halteres are free. The larvse have visually a perfectly differentiated head (Eucephala), more rarely a I'ctractile jaw capsule (Tipulidce, Ceci- domyia); they live in water, in earth, and in vegetable matter (galls and fungi), and some of them have a respiratory tube. After moulting the larval skin the eucephalous larvae become quies- cent or freely moveable pupae ; the latter are provided with tracheal gills on the neck and tail. The insect when hatched swims, till the wings are hard, on the burst pupal skin as on a boat. The females of many species suck blood (gnats), and become a veritable pest in certain districts where they appear in swarms. Fam. Bibionidae QMvsciformcs'). Body fly-like ; antennas six- to eleven- jointed. The abdomen has seven segments. Bibio marci L., B. hortulamis L. The males are black, the females brick red with a black head.
