The tribe Tryxalides includes a great many species of grasshoppers. In them the front of the head joins the upper part at an acute angle (Figs. 165 and 173). This tribe and the Acridiides are the most numerous in species of the family. To the latter belong most of the migratory locusts of the New World (Fig. 175, Galoptenus spretus). A Spanish species of this trilje, Eupre- pocnemis 'plorans, though provided with well-developed wings, possesses the remarkable habit of seeking shelter by jumping into the water and attaching itself below the surface to the stems of plants. The tribe Pamphagides- includes some 200 species, found chiefly in Africa and the arid regions near the Mediterranean Sea. They are mostly apterous forms, and this circumstance has, FlO. 183.—Pyrgoimrpha grylloides. South Europe. (After Fischer.). Fig. ISi.—Xiphooera (Hoploloplm) asina. S. Africa.
