These gaily colored flies, so useful to ag-riculturists from their habit of feeding upon Plant-lice, closelyresemble the wasps in form and coloration, Jiaving hemis-pherical heads,, large broad eyes, and rather flattened bodiesornamented with yellow bands and spots. The wings have thethree basal cells much prolonged, the third longitudinal veinsimple, a spurious longitudinal vein between the third and fourthlongitudinal veins ; while the fourth longitudinal vein is united 398 Fiar. 317. at its eud with the thud, and there is no intercalary vein. Thegenital armor of the male is unsymmetrical, and there is noempodium. They hover in the hot sunover and about flowers, resting uponthem to feed on their sweets. Thelarvae either live in the water, when thebody ends in a long extensile breathingtube ; or are terrestrial, living in decaying wood, or parasitically in nests ofbees, or, as in Syrphus, live among plant-lice. The singular spherical larva of Mi-crodon glohosus (Fig. 317 ; a, puparium ;s, spiracular tubercles; v, vent; 6,anterior view of the same ; c, larva justbefore pupation) is found, according toMr. Sanborn, under sticks in companywith sliells. Milesia strikingly resembles, in its style of coloration andform, the common large yellow wasp. The antennae are short,drooping, with a stout oval terminal joint,
