This paper reports three new species of grasshoppers from Yunnan Province. Type specimens are preserved in the Research Institute of Entomology. Zhongshan University, Guangzhou.Tagasta brachyptera, sp. nov. (Figs.1-3, 9-10)This new species is allied to Tagasta yunnana Bi and T. rufomaculata Bi, but the elytron shorter, only a little beyond the middle of hind femora in male and a little beyond the two thirds of hind femora in female; elytra without numerous small reddish spots along the longitudinal veins; wing dark orange-red but the apex pale; the inner kneelobes of the hind femora without dark bands at the base.Holotype (?), Allotype(?), Paratypes3(?)1(?), Yunnan: Yuanyang, 7-21-Ⅶ-1986, Tao Hong.Apalccris antennata, sp.nov. (Figs.4-5, 11-12)The new species differs from the other species of the genus Apalacris in the following ch acters:1.The antennae longer, beyond the middle of hind femora and the length of middle segment about 4.3 times its width in male, and beyond the base of hind femora and the length of middle segment about 4 times its width in female;2.Elytron shorter, both sexes not reaching the apex of the abdomen.Holotype(?), Allotype(?), Yunnan: Yuanyang, 21-Ⅶ-1986, Tao Hong.Ceracrispui, sp.nov. (Figs.6-8, 13-14)The new species is closely related to Ceracris fasciata (Br.-W.), from which it may be distinguished by the following fearures:1.The antennae longer, reaching the middle of hind femora in male and beyond the hind margin of the pronotum in female, the length of middle segment about 3 times its width in both sexes;2.Elytron of both sexes shorter, only reaching the front of the knee of hindfemora;3. The epiphallus different in shape.Holotype(?), Allotype(?), Yunnan: Yuanyang, 5-Ⅷ-1986, TaoHoug.
