Trochanter composed of two rings. Larvae phytophagous, resemble caterpillars. Fam. Tenthredinidae (Leaf-wasps). Saw-flies. Abdomen sessile with short borer. The larvie have rarely three, usually nine to eleven pairs of legs, and resemble caterpillars. The females lay their eggs in the epidermis of leaves, the puncture causes the flow of .sap. which the egg imbibes and thereby increases in size. The young larvae feed on leaves, often in early stages live in societies, and become pupae in a cocoon. They are distinguished from the caterpillars by the greater number of legs, and by the two ocelli on the horny head. Lyda betulee Tenthrcdo (Atlialia) larvas sometimes on roses. Nematus ventrlcxsus Klg., larvae on gooseberries. Cimbex frin a fata L. Fam. Uroceridae (Wood-wasps). Abdomen with first tergum split, and usually long, freely projecting oviposi- tor (egg-borer). The females bore holes in wood and deposit // W//>/x/\ their eggs therein. The larvae bore further into the wood and live a long time. Sin .r L.
