The Raptoria, or "graspers," form one family, the Majitidce^ as odd in appearance as their habits are unusual. They are clumsy, heavy-bodied insects, with short, broad wings, the middle and hind-legs rather weak, but with an unusually long and slender prothorax, to which is attached a pair of huge forelegs, armed with sharp spurs and spines. The head is usu- ally much broader than the prothorax, with prominent, often globular eyes, short antennae, and so set as to be capable of lat- eral motion. It is, in fact, the only type capable of turning its The insects are, as a rule, sluggish, those occurring with us incapable of rapid motion, depending entirely upon such prey as The Oriental roach, Periplaneta orientalis.—a, the male ; b, the female ; c, egg-case. comes within easy reach, and securing this through their often remarkable resemblance to the vegetation among which they lurk. In other countries there are some more active species, capable of pursuing and capturing their prey. Their colors are green or yellowish, like leaves, or brownish, like bark ; the wing- covers sometimes mottled and roughened to mimic an irregu- larity or overgrown injury on a trunk or branch.
