The present paper deals with descriptions of 2 new species of the Genus Thoressa . The type specimens are kept in the Entomological Museum, Northwest Sci Tech University of Agriculture and Forestry. 1. Thoressa abprojecta Yuan et Wang, sp.nov.

Holotype: ♂, Mt. Qingling, Shaanxi Province, 29 Ⅵ 1996, coll. LI Yu fei. Paratypes: 1♂, same location and collector as Holotype, 28 Ⅴ 1995; 1♂, Mt. Lu, Sichuan Province, 1996, coll. WANG Bing hong. 2. Thoressa breviprojecta Yuan et Wang, sp. nov. (Fig.2) This species resembles Thoressa fusca (Elwes 1893), but differs from the latter in the following characters: 1) body dark brown, but the 1atter pale brown; 2) underside of hindwing brown, but in the latter light ochreous brown; 3) gnathos with apical area curved upwards and acuminate top, but in the latter, gnathos short and straight with apical area blunt.
