Century Dictionary and Cyclopedia
    • insecta A class or other large division of invertebrated animals, to which different limits have been assigned. With Linnæus, a class divided into eight orders: Coleoptera, Hemiptera, Lepidoptera, Neuroptera, Hymenoptera, Diptera, and Aptera. But the last of these orders included crustaceans and arachnidans, so that in this sense Insecta corresponds to the Cuvierian Articulata, the Latreillean Condylopoda, or the modern Arthropoda, one of the main branches of the animal kingdom.
