Kertesz, Cat. Dipt. Vol. 6, p. 8 (1909). 
Characters. — Species of five or six mm, length; head globose, thorax very strongly gibbous, 
abdomen slender. Eyes contiguous above the antennz, separated below; antenne three-jointed, the 
third joint long and tapering and merging into the long apical arista; proboscis and palpi small and 
retracted. Legs slender, the femora not thickened, in the genotype the apex of the tibize and the basal 
joints of the tarsi of the male dilated. Wings dark-colored, stigma strong and long, second vein curving 
forward at tip to meet the costa, third vein forked, discal cell large, complete, emitting three veins, basal 
and anal cells long. 
Type species : Homolocnemis nigripennis Philippi, from South America (Pl. 5, Fig. 41). The 
recently described Brachystoma adelensis Miller from New Zealand, apparently belongs here. The full 
venation is somewhat suggestive of Bombyliidz but the habits of the New Zealand species, in 
darting hither and thither over the surface of pools of water, show the Empidine affinites,

3. GENUS ANOMALEMPIS, NOV. GEN. 
Characters. — Head globose, no ocellar prominence; front (female) occupying about one-
