The empodia are wanting. Family BOMBYLIID^ (Bom-by-li'i-dae). The Bee-flies, These flies are mostly of medium size, some are small, others are rather large. In some the ^ body is short and broad and densely clothed with long, delicate hair (Fig. 563). Other species resemble the horse-flies somewhat in appearance, especially in the dark color or markings of the wings ; but f^^- s^z^-Bombyiius, these can be distinguished from the horse-flies by the form of the antennae and the venation of the wings. The antennae are usually short; they are three-jointed ; the third segment is not ringed; the style is sometimes present and sometimes wanting. The ocelli are present. The proboscis is sometimes very long and slender, and sometimes short and furnished with fleshy lips at the ex- tremity. Vein III of the wings (Fig. 564) is four-branched ; cell III3 is sometimes divided by a cross-vein ; cell V3 is obliter- ated by the coalescence of veins Vg and VII^; in a few genera cell V, is also obliterated by the coalescence of veins Vj and V^; cell VIII is narrowly open, or is closed at or near the border of the wing. The alulets are small or of moderate size. The adult flies feed on nectar, and are found hovering over blossoms, or resting on sunny paths, sticks or stones ; they rarely alight on Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the origina
