This is a genus of large Hies; occasionally depauper- ate individuals as little as 6 mm. in body length and 14 mm. in wing expanse, but most species are much larger and some of these species comprise the largest known bee flies. The head is large, subglobular, and loosely attached to the thorax; the occiput is extensive but slopes strongly backward to the margin of the large, deep, central recess. The face is either bluntly protuber- ant, or very frequently acutely conical. The antennae are relatively small, very widely separated. The third segment is characteristically attenuate and has an artic- ulate, separated, apical, bristle-tipped style; this char- acter with rare exceptions separates Exoprosopa Mac- quart and allied genera from the Villa Lioy group of related genera. The antenna! style is without an apical whorl of hairs such as found in the Anthracinae. The proboscis in Exoprosopa Macquart is slender, varying from no longer than the oral recess to others where it is almost twice as long. The flies o
