The venation- of the wings much resembles that of the genus Promaelms, though the form of these insects is very different. In Mallophora and Promaeus the venation is as represented in Fig. 177, where, as will be seen, the second vein (Fig. 177, b) forks, while in the genus Asilus (Fig. 172) the third vein is forked, though in all three genera the third joint of the antennae (Fig. 175) ends in a prolonged bristle. One of the most common of these pests, which I am informed by Dr.

One of the most common of these pests, which I am informed by Dr. Hagen is Mallophora orchid, Weid, (Fig. 178) is one inch long, and expands one and three-fourths inches (Fig. 179). The head (Fig. 175) is broad, the eyes black and prom- inent, the antenna? three-jointed, the last joint terminating in a bristle, while the beak is very large, strong, and, like the eyes and antenna?, coal black. This is mostly concealed by the light yellow hairs, which are crowded thick about the mouth and between the eyes. The thorax is prominent and thickly set with light yellow hairs. The abdomen is narrow, tapering, and covered with Fig. 178. Fig. m- yellow hairs except the tip, which is black. Beneath, the sect is clear black, though there are scattering hairs of a gray- ish yellow color on the black legs. The pulvilli, or feet pads (Fig. 176, 6), are two in number, bright yellow in color, sur- mounted by strong, black claws (Fig. 176, a), while below and between is the sharp spine (Fig. 176, c), technically known as the empodium. The habits of the flies are interesting, if not to. our liking. Their flight is like the wind, and perched near the hive, they rush upon the unwary bee returning to the hive with its full load of nectar, and grasping it with their hard strong legs,.
