QWim\<m:.wm3 ][;^aJKtas Il-inopus T]oi*]*,. ORTIIOPTERA. 557 The Orthoptcra are insects* which undergo a semicomplcte 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 month of the Orthoptera is composed of a labrum, two mandibles, two maxilla?, andfour palpi; those of the nia.\illic have always five joints; the labial jialpi, 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 lu-e generally composed of a nuich greater number of joints. JIany, inaddition to the conijiosite eyes, have two or throe ocelli. Th
