Not infrequently, where an outbreak of caterpillars occurs, wasps will be seen carrying them off to their nests in considerable numbers; we have observed them at work on the cotton boll-worm and leaf-worms in the South. But two genera are com- mon in the East. Polistcs are black ringed with yellow, or are brownish, and have long, spindle-shaped abdo- mens. Their nests are composed of a single comb and are attached by a short stem. The genus Vespa includes the hornets and yellow-jackets, which are black, spotted or banded with yellow, or yellowish-white, with a short, stout body, and the abdomen attached by a very short peduncle. Their nests are formed of several layers of combs, all of which are covered with a waterproof covering of paper, made from weatherworn wood of stumps, trees, fences, and buildings. The nests are gradually enlarged, new combs being added and the outer envelope being enlarged to cover them. The males and workers die in the fall, and the females hiber- nate over winter and start a new colony in the spring. 3.
