(Original.); f^^'^The mouth-parts of the common locust are shown in figure 40, and it is evident that the different parts are adapted for biting and holding the object while biting. With the squash bug, however, the parts are not adapted for biting, but for sucking. The lower lip or labium forms the 4- jointed, grooved sheath, and the mandibles and maxillae form the four lance-like piercers, while the labrum is a scale-like flap to which, apparently, the piercers are attached. It will be obiserved that there are no palpi on either the maxillae or labium, but the parts have been modified for piercing and sucking. Fig. 40.—The mouth parts of the com- mon locust dissected out, the upper lip or labrum, (a) the mandibles, (b) the maxillse, (c) and the under lip or lab- ium, (d) (Original.).
