The antennae (Fig. IS, a, a) are the horn-like jointed organs situated between, or below and in front of, the large compound eyes of all insects. They are sometimes short, as in the house-fly, and sometimes very long, as in crickets and green grasshoppers. They may be straight, curved, or elbowed. In form they are very varied, as thread-like, taper- ing, toothed, knobbed, fringed, feathered, etc. The antennas of many Hymenopterous inse

The function of the antennae is now pretty well, if not wholly, understood. That they often serve as most delicate touch-organs no observing apiarist can doubt. Tactile nerve-ending hairs are often found in great numbers. With the higher insects, like most Hyme- nopterons, this tactile sense of the antennae is doubtless very important. It is now fully demonstrated that the sense of smell is located in the antennas. Sulzer, in the eighteenth century,.
