GRASSHOPPERS AND CRICKETS 67 Directly back of the head, there is a large capelike seg- ment bearing a pair of legs. This is the first division of the thorax, and is called the prothorax. The remainder of the thorax is made up of two parts united. The one in the middle is the mesothorax; this bears the front wings and the middle legs. Behind this is the metathorax ; this bears the hind wings and the hind legs. The front wings Oblong I,eaf-winged Grasshopper are long and slen- der, and when at rest serve as a protective covering to the hind wings. The latter are then folded in longitudinal plaits like a fan. When the grasshopper is flying, the front wings are extended at right angles to the body, and the hind wings are stretched out. The abdomen is composed of a number of joints or seg- ments, which move freely upon one another at their points of contact. In female specimens the abdomen ends in four-pointed projections by means of which the hole in the ground for the eggs is made; these form the ovipositor or egg-depositor. Short-horned Locusts The common Grasshoppers or short-horned Locusts form one of the most important families (Acridiidae). These have short antennae or " feelers," short ovipositors, and but three joints to the tarsi— the short joints at the ends of the legs. They feed upon grasses and other forage crops, and are often very destructive. In many of the males, there is a sound-producing Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Weed, Clarence Moores, 1864-1947.
