. Economic entomology for the farmer and the fruit grower, and for use as a text-book in agricultural schools and colleges;. Insects; Pests. THE INSECT WORLD. 87 age in roads, fields, or meadows, but not favoring dark woods. They have no external ovipositor, but the female is furnished with four horny valves, between which the eggs pass, and which are also useful in making the hole, in soil or wood, into which the eggs are laid. The term "short-horned," as applied to these insects, is relative, and means that the antennae are moderately stout, the joints well marked, and the whole member not as long as the entire insect,—in fact, rarely even half as long. A curious Fig. Rocky Mountain locust ovipositing.—a, a, females with abdomen inserted in the soil; b, an egg-pod broken open and lying on the surface ; c, a few scattered eggs ; d, section of soil removed to show eggs being put in place ; e, an egg-pod completed ; /, an egg- pod sealed over. character is a pair of ears situated one on each side of the basal segment of the abdomen, and we therefore expect and do find that most of the species are capable of making some kind of song or noise, though this ability is confined to the male. A series of species characterized by a very receding front, meeting the vertex of the head in an acute angle, is referred to the sub-family Tryxalmcz, of which there are many species throughout our country, none of them abundant enough to be injurious. They are partial to low, sedgy land or meadows, es- pecially on sandy soil, and I have met with the species most abundantly near the sea, or on the sandy plains not far inland. Some species are common on or near cranberry bogs, but are not injurious. Quite a series of species is referred to the sub-family CEdipodincB^.
