Katydids.—^The katydids include several species, but the one most properly called katydid has broad, concave wings with rather prominent veins, quite strongly Fig. 33.—Conocephalus ensiger, female—natural size. (After Lugger.) The name of the species is Cyrtophyllum concavum. They are noted for their song, and sing particularly during the twilight and early part of the night. This species is the best singer of the katydids. Their life history is practically the same as that of Conocephalus. A species nearly related to this is the angular-winged katydid, which deposits eggs on the surface of twigs, the eggs overlapping each other like tiles on a roof. Stone Crickets.—In this family also have been placed the stone crickets. Most of them are included in the genus CeuthojMlus. Quite a large number of species is included in this genus. They have changed from the food habit of.
