ORTHOPTERA. 557 The Oithoptera are insects* which undergo a semicomplete metamorphosis, all the changesbeing reducible to the increase and developement of wing-covers and wings, which begin toappear under a rudimentary form in the pupa. This pupa and the larva resemble the perfectinsect in other respects, walking and feeding in the same manner. The mouth of the Orthoptera is composed of a labrum, two mandibles, two maxilljE, andfour palpi; those of the maxilla; have always five joints; the labial palpi, as in the Coleoptera,have only three. The mandibles are always very strong and horny; the tonguelet is con-stantly divided into two or four plates. The form of the antenna; varies less than in the Cole-optera, but they are generally composed of a much greater number of joints. Many, inaddition to t
