Two new combinations are proposed in Eupeodes (s.str.), i.e., Eupeodes (E.) nuba (Wiedemann,1830), Eupeodes (E.) latimacula (Peck, 1969). A key to the known Chinese species is also given. All type specimens are deposited in the Insect Collections of Shanghai Agricultural College.1\ Eupeodes (Eupeodes) alaceris He et Li, sp.nov.(Fig.2) Male. Eye bare. Vertical triangle longer than suture of eyes. Angle of frons at approximation of eyes 85 degrees. Face occupying 48% of head width. Postocular orbits near vertical triangle medium width. Female. Similar to the male. Dusted spots on front elliptical, occupying 9/10 of the width of frons. Dark color on frons extending beyond 1/2 of distance between front ocellus and base of antennae. Postocular orbits somewhat broader than in male. Yellow spots on tergites 3 and 4 slightly narrower than in male. Length: Body 11 0￣11 5 mm, wing 10 0￣10 5 mm. Holotype , allotype ♀, Shaanxi: Wugong (34 2°N,108 2°E), July.1,1983.Paratypes, 4,2♀♀,ditto. The male of this new species is similar to E. (E.) qingchengshanensis He, female of which is unknown, but differs from the latter in the following characters: angle of frons at approximation of eyes 85 degrees; cheek yellowish brown; genitalia different.2\ Eupeodes (Eupeodes) lepidi He et Li, sp.nov.(Fig.3) Male. Eye bare. Vertical triangle rather longer than the suture of eyes. Angle of frons at approximation of eyes 85 degrees. (The face is depressed). Postocular orbits near vertical triangle narrow. Length: Body 10 5 mm, wing 9 5 mm. Female unknown. Holotype , Ningxia: Yanchi (37 7°N,107 4°E), June.15,1988,by Sun Xingquan. This new species is rather similar to Eupeodes (E.) chengi He, but differs from the latter in the following characters: yellow band on 3rd abdominal tergite rather broad
