This paper deals with two new species of the genus Alopecosa belonging to the family Lyeosidae。 Type specimens are deposited in the Teacher's University of Inner Mongolia. The diagnostic characters of new species are given below. 1. Alopecosa curtohirta sp. nov. (fig. 1) HoIotype, allotype♀, paratypes 12♀♀; Huhhot (40.8°N, 111.7°E), Inner Mongolia, May 12, 1985。 Length of males 7.1—7.5mm. carapaee dark brown, median band light brown, lateral band lacking. Anterior row of eyes proeurved. AM larger than AL. Width of elypeus about equal to the diameter of AM. Chelicera reddish brown in dorsal surface, promargin 3 teeth, retromargin 2 teeth. Legs yellow, with ligh brown annulations. Dorsal surface of abdomen brown with white pubescence, ventral surface yellow. Cardiac pattern absent。 Male palp cymbium with 2 pairs of stout and curved bristles. Shape of appophysis as shown in fig. Length of females 10.8—11.4mm。 All marking of the body clearer than that of the male. Epigynum with a pair of copulatory tube stout and short. This new species is allied to Alopecosa albostriata (Grube, 1861), but can easily be distinguished frim the latter by the different shape of epigynum of female as well as median apophysis of male palp. 2. Alopecosa hingganica sp. nov. (fig. 2) Holotype♀, paratype 1♀, Arxan Hinggan Meng (47.1°N, 119.9°E), Inner Mongolia, June 25, 1984. Length of females 11.3—11.5mm. Median band yellow, lateral band yellow, continuous and clear, extending to clypeus。 Anterior row of eyes weakly proeurved, AM slightly larger than AL. width of elypeus slightly larger than the diameter of AM。 Promargin of ehelieera 3 teeth, retromargin 2 teeth. Legs reddish brown, with dark brown longitudinal bars. Dorsum of abdomen dark yellow, with a pairs of brown longituinal bar in the lateral sides. This new species is related to Alopecosa hokkaidensis Tanaka, 1985, but can be distinguished from the latter by the different shape of epigynum.
