In the Saltatoria, or jumpers, we find themost destructive species, and they separatereadily into three families : the Acridiidcs, or short-horned grasshoppers ; the Locustidce,or long-horned grasshoppers and katy-dids ; and the GryHides, or crickets, whichhave long horns or antennee like the Locustidce,but cylindrical instead of flat, sword-like ovipositors. The AcridiidcE, or short-horned grasshoppers, are among themost common and best known of our insects, flying up or jump-ing out of the way, however one turns, among grass or low herb- Egg masses ofStagynomantis Car-olina, from aboveand from side. 86 AN ECONOMIC ENTOMOLOGY.
