Bacillus, whose long body, together with the elongate legs, looks like a dry branched twig; some species in South Europe. In the East Indian, Phylliwm siccifolvwm, the Leaf-insect, the broad abdomen and elytra are leaf-like. 7. The Termites, (genus Termes, and others) possess four large, thin wings, which ai-e all alike, and cannot be folded up. The antennse are short, and moniliform, the legs are like one another. The Termites are specially remarkable for living in large colonies, including, besides fertile males and females, a large number of apterous and blind individuals in which the sexual organs (in some examples male, in others, female) remain in an immature condition. Some of these wingless individuals are possessed of larger heads and more powerful mandibles, and are termed "soldiers, " whilst the others are termed "workers"; the nest is made by the workers, either by gnawing passages and chambers in tree-trunks and lining them with a layer of excreta, or by constructing such dwellings out of excreta and earth. They often form extensive tunnels in the ground. The soldiers defend the nest against attack. Before pauing the males and females leave the nest, fly about for a.. Fig. 212.

Then, in many forms, the abdomen of the female enlarges* to an extraordinary extent. Besides the winged males and females there are apparently others which, as regards the stnioture of the wings, remain at one of the older larval stages, in which merely short stumps are present; they do not leave the nest, and only become functional if none of the males or females which f
