These are more complicated than the mandibles and each one bears a slender prolongation like an anteima, called a pal- pus. Finally, below 98), which is notched. Fig. - One mandible of i grasshopper. locust or -The thorax of the the maxillse is the lower lip (Fig. and bears two slender palpi. The thorax and its appendages locust is composed of three divisions: the prothorax, the division next the head; the mesothorax, the middle division; and the metathorax, the last division (Fig. 94). We can distinguish these divisions by the appendages they bear. For example, there are three pairs of legs on the thorax, of which the first pair is borne by the prothorax, the second pair by the mesothorax, and the third pair by the metathorax. The legs are made up of segments with joints, hence are fitted for movement. The hind pair is very long, large, and muscular. Moreover, the thorax bears two pairs of.
