In this paper, two new species of Helina and a known species of Scathophaga are discribed. All the type specimens are preserved in the Shanghai Institute of Entomology, Academia Sinica, Shanghai, China. 1. Helina ateritegula, sp. nov. (Figs.1～3) ♂: Body length 7.5 mm. This new species is closely related to Helina alternimacula Xue et Wang, 1986, but differs from the latter in: Legs wholly black; abdomen without deformed spots; lst sternite bare; male surstyli backward on distal part in lateral view. ♀: Unknown. Holotype ♂, Mt. Erlang (Ganhaizi, 2790 m; 29°54′N, 102°09′E), Sichuan Prov., 01 Ⅶ 1988, coll. by Feng Yan. 2. Helina arcuatiabdomina, sp. nov. (Figs.4～8) ♂: Body length 7.0 mm. This new species is closely related to Helina calceicerca Xue et Wang, 1986, but differs from the latter in: mid tibia without pv seta; on 3rd and 4th tergites of abdomen without spots; male cercus without a projection on anterior margin of distal part. ♀: Unknown. Holotype ♂, Mt. Erlang (Forest Farm, 2680 m; 29°54′N, 102°08′E),Sichuan Prov., 15 Ⅸ 1990, coll. by Feng Yan. 3.
