The existence and the niimher of legs of the larva, thepermanent or variable form of the head, the comparativestructure of the organs of the mouth with those of theimago, the number of the spiracles and disposition of thetrachese, the moultings of the skin, and the quiescent oractive state of the pupa, are all important considerations,upon which the distribution of insects from the characters oftheir metamorphosis may be effected. Hence the Lepidoptera (figs. 35, 36, and 37), are dis-tinguished by the number of legs, scaly head, &c. of the.
