The body is covered with a hardskin, and usually has head, tliorax, and abdomen distinctlys parated. The abdomen of the female is often supplied with a sting,or with an ovipositor, by means of which she can pierce intoanimal or vegetable matter to insert her eggs. In some casesthis is done by means of a kind of borer; in some, as withthe Saw -flies, by means of a kind of saw-like apparatus. The laivte are usually maggot-Hke and footless, with themouth commonly but slightly developed ; but in the family of ENTOMOLOGY. 387 the Sawflies (Tenthredinidce) the larvae are more like Butterfly-caterpillars, and have usually, hesides the six true feet, twelveto sixteen sucker-feet. (The Corn Sawfly, see p. 94, is anexception, being footless.). Turnip Sawfly (AthaUa siiinanim): caterpillars, pupa, and pui^a-case. Sawfly,magnified, with lines showing nat. size. Pupae are inactive, with the limbs of the future insect dis-tinguishable, but wrapped in sheaths and folded beneath thebreast. Change sometimes takes place in cocoons. This Order contains the families of Sawflies {Tcnthrediniche),Sirices {Uroceridce), Gall-flies (Cynipidcc), Ichneumon-flies{Ichneumonida) (and other kinds of Parasite-flies), Ants{Formicidce), Wasps {Vespida), and various kinds of Bees[Andrenidce and Ajndce), classed under the head Mdlifcra.
