From simmondsii it appears to differ in size (2-8 mm. long), white hairs on the frons anteriorly, in having a more distinct bifid process apically on antennal joint 3, and in having broader yellowish knees.

St. Petersb., vol. xvii, 1912; Engel, p. 127, Die Fliegen. d. Pal. Eeg. Lief. 69 (Bombyliidae), 1933.) This peculiar genus has been adequately described by Loew. Its chief diagnostic characters are the presence of only 3 posterior cells in the wings, absence of a discoidal cell, the straight second longitudinal vein and vein between submarginal cells, the apically acute and stalked anal cell, the broadly triangular axillary lobe and the apically spined and peculiar third antennal joints (see text- figs. 257, a and b). Additional points of interest are: eyes in $3 usually in contact above but sometimes separated; the palps are either long and well developed, with the apical joint slightly thicker than basal one or the palps may be very short in some species; proboscis Text-fig.
