Myriads of these creatures infest the oak forests, making the stridulous concerts so characteristic of them during the entire day. Whittier says of them, they " Stab the noon silence With their shrill ; Or, in popular language, zeelng expresses their note, if it can be called a note, for it is the result of a mechanical rasping.

Now and theu is found in the fields a very large, locust-like insect, of a beautiful grass- green hue, and having at the end of its tail a long, flat-bladed instrument called an ovipositor, and used for the purpose of boring holes in the earth and placing its eytis below the surface. This is the Great Green Grasshopper {P7/(isgonura, or Acn'da viridiKsima), which unfor- tunately loses its soft, light green color soon after death, and as it dries becomes a dirty yellowish-brown. It is a very fine insect, often measuring two inches in length, and three inches and a half over the expanded wings. It seems to be rather capricious in its appear- ances, in some years being quite plentiful, and in others hardly to be seen. The jaws of this insect are wonderfully powerful, and its captor will act wisely to keep his finger out of their reach. The internal structure of this grasshopper is extremely interesting, and on account of its large dimensions are easily studied. The gizzard is especially worthy of notice. A SINGULAR insect is the Eyed Pterochroza. It is one of those beings in which are found a strong resemblance to other parts of creation. In this insect, we have an example of a member of the animal kingdom reproducing with startling fidelity the forms, colors, and even the accidental variations of leaves and flowers, thus exhibiting another phase of that wonderful adaptive power,
