INSECTS, INSECTA, in Natural History, a smaller sort of animals, commonly supposed to be exsanguous; and distinguished by certain incisures, cuttings, or in- dentings in their bodies. The word is originally La- tin, formed of in, and sero, "I cut;" the reason of which is, that in some of this tribe, as ants, the body seems to be cut or divided into two; or because the bodies of many, as worms, caterpillars, &c., are com- posed of different circles, or rings, which are a sort of incisure.
