If the Carolina locust is not so easily obtained in full series as another species, any other grasshopper will do as well. All the grasshoppers and locusts belong to the group Orthoptera (or straight-winged insects). Other Orthoptera are crickets, katydids, walking sticks, mantes, cockroaches, etc. Some of these should be stud- ied, and compared with the grasshoppers in size, in relative development of organs, in relative powers of locomotion, in food, in habits, in instincts, and in economic importance. A good general idea of the group wiU thus be obtained. THE SQUASH BUG. {Anasa tristis.) Haunts and Habits. — This insect is an annoying pest of the kitchen garden. Adults, young, and eggs may all be collected from the same vines of squash, cucumber, or pumpkin. The adults are black- ish brown above, and dirty yellow beneath. The nymphs are smaller, and* relatively shorter and more rounded, than the adults. The eggs are laid in little clusters on the young leaves. No net will be needed for collecting these '^^''^'" ^''''• bugs. They may be pushed directly into the c3'anide bottle. While collecting, observe the following 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 Needham, James G.
