(1) Kritempis, subgenus of E»pis. Type E. algira, Macquart: includes livida, Linnaeus, Maquarti, Becker 
(— geniculata, Macquart, not Zetterstedt), macropalpa, Egger, migrimana, Becker, sibillina, Bezzi. ^ Anal vein faint, not 
reaching margin, discal cell not truncate, with the first or the first and second posterior veins not reaching the margin, 
cubital fork rather acute; a small bristle in comb at tip of hind tibize behind; male facets scarcely enlarged, no rows 
of long bristles beneath the middle femora, upper lamelle of pygidium often very large, always much larger than the 
side lamellze, in //vida composing almost the whole of the pygidium; species never very small. 
(2) Leptempis, subgenus of Enpis. Type E. grisea, Fallen. Rather large, narrow-bodied, long-legged, wings 
ample, never blackish, sometimes maculated, anal vein distinct to margin; hypopygium with side lamelle long and 
narrow, upper lamelle rather prominent and bilobed, penis long and usually very undulated ; female legs extensively 
yellow. 
(3, Rhadinempis, subgenus ot Empis. Type E. Bazini, Collin, the only assigned species. Resembles the Holoclera 
group of Rhamphomyia, but has the third vein forked. Antenna short, the third joint short and pointed, about as long 
as the basal two together, and half as lons as the microscopically pubescent arista; acrostichals absent, dorsocentral 
bristles uniserial; axillary excision of wings greater than a right angle. 
(4) Originally assigned to the Bombyliidze, but superficially resembling T'malphes fumosa, Hutton. Type, and 
only species, F. perspicuus, Hutton. Eyes contiguous, upper facets coarser; third antennal joint swollen at base and 
gradually tapering to a long point; proboscis short; thorax black, humeri brown, scutellum yellowish, pleurz silvery; 
abdomen linear, brown; wings smoky, stigma large, third vein forked, third basal cell closed and petiolate, fourth vein
