Mansfield and of which the adults were reared in a laboratory of the Department of Agriculture in Pretoria from a batch of bombyliid larvae found both in egg-packets of the brown trek locust {LocKfitana pardalina) and in loose soil in association with such egg-packets. This bombyliid cannot be referred to any other subfamily of the Bombyliidae but to the Cyrtosiinae [renamed Platypyginae]. With the latter it agrees in certain characters, such as the re- duction of the wing-venation, the presence of only one submar- ginal cell, the peculiar reduced and somewhat triangular mar- ginal cell, the characteristic quadri-articulate antennae, the slight indentation in the inner margin of the eye opposite the antennae, the absence of distinct spines and spicules on the legs, absence of macrochaetae on body, the arched or humped and convex thorax, broad and arched abdomen, and rows of small shiny depressed black spots on abdomen (present in some cyrtosiines [platypygines] ). In certain other characters, such as the vei-y much reduced, rudimentary or vestigal proboscis, the widely separated ocelli of which the middle, slightly anterior, one is remarkably large, the less developed occiput, the sculptured or punctured thorax and abdomen, the excavate venter, and even more convexly humped or arched thorax and abdomen. It, however, differs from other known genera of the Cyrtosiinae [Platypyginae] to such an extent that at least a distinct section or tribe of the latter is indicated to include it. As the life histories of all the other known South African cyrtosiine [platypygine] bombyliids (if not of the world) are unknown, the discovery of this genus and its host is of great importance. The genus is characterized as follows: B
