Cuvier's animal kingdom : arranged according to its organization cuviersanimalkin00cuvi Year: 1840 IIYMENOPTERA. 581 Fig, 115.—Phryganea candis.—A. B. grating ; . Imago. These larvsc are elongate, nearly cylindric, with a scaly head furnished with strong mandibles, and a small eye on each side ; six feet, of which the two anterior are shortest and thickest, and the other four longer ; the body is com- posed of twelve joints, of which the fourth has a conical tubercle on each side in the majority of the species ; the terminal segment is furnished with two moveable hooks ; the majority also possess two series of white flexible filaments, which appear to be respiratory organs. When ready to assume the pupa state, they fix their cases to some sub- stance under water, closing each end with an open grating, which, as well as the cases itself, varies in the different species. The pupae have in front two hooks, which cross each other like a beak, and with which they make their way through the grating, [immediately before they assume their final form,] when, although pre- viously immoveable, they walk or swim with agility, by means of the'r four fore-legs, which are free and fringed. The pupae of the larger species crawl up plants out of the water, where they throw off their skin, but the smaller ones merely come to the surface, and are there transformed into winged insects in the same way as Gnats, their old envelope serving them for a boat. Some have the hind wings evidently larger than the fore ones, and folded. Sericostoma, Latr., has in one of the sexes the maxillary palpi dilated into a mask covering the face ; in the other sex they are fiUform, and 5-jointed. Phryganea proper, has the mouth alike in both sexes, and the palpi shorter than the head and thorax, and slightly villose. P. grandis, [and a great number of other species, well known to the angler and fly-fisher]. Mijslacida, Latr., has th
