The under side ofthe head is prolonged into a beak shape, with the parts of themouth joined into a kind of sucker-like sheath, out of whosefree end the bristle-formed jaws project. The larvae and pupa3 much resemble the perfect insect inshape, and in the first stage are active, in the second aresluggish. The male of the T. jjhysapus (Kirby) is wingless. The Corn and Potato Thrips are examples of this Order. 5. NEUPvOPTEPiA (Limijeus).Dragon-flies, May-flies, Stone-flies, &c. Wings four, nearly equal in size, membranaceous, withmany *nerves sometimes forming a network. The under ENTOMOLOGY. 385 wings are occasionally folded. Head usually with jaws, butthese are sometimes absent, as in the May-flies, which, onlyliving for a short time, do not require apparatus for feedingwith. Abdomen generally long and 1, Golden-eye, Glmjsopa perla; 2, eggs of Chnjsopa; 3 and 4, larva;5 and 6, cocoon, nat. size and magnified. Larvae with six legs ; pupae various, in some cases active, andsomewhat resembling the perfect insect; in others inactive,with the limbs folded beneath them. The famihes of the Dragon-flies (Lihellulidcs), Stone-flies(Perlida), and May-flies {Ephemerichf^, pass their first stagesin the water, and have active pup?e as well as larvae. Ilemerohiidce (see C. licrla, figured above) are peculiar inlaying eggs fixed by a long stalk of a viscid secretion; thelarvae feed ravenously on Aphides. In the eleven families ofwhich Neuroptera is composed, it is said that there is scarcely a leading characteristic of the Order which does notmeet with an exception. G. TEICHOPTERA (Kirby).—Caddice-flies.
