The antennae are comparatively short, with not more than twenty-four joints. The first joint, or scaju, is generally stouter and longer than the second, which is often more or less globular, and is sometimes called the ring-joint. The remaining joints form the flayellum; they are sometimes long Fig. 5.—Antennffi of (A) Locusta, (B) Gomphocerus, (C) Acrida. and uniformly cylindrical; sometimes the flagellum is much thickened towards the base and tapers more or less towards the extremity; and more rarely the joints of the flagellum are flattened; or some of the terminal joints are expanded or even form a club.
