摘　　要：1980年8—11月,在云南、贵州和四川三省进行蝗虫调查,采到许多标本。现将蝗亚科(Acridinae)中的一新属二新种记述如下。模式标本存陕西师范大学生物系。 长翅黄佛蝗Chlorophlaeoba longusala Zheng,新种 雄性 体中小型。头部较长,长于前胸背板,颜面极倾斜,颜面隆起狭,在中眼以上侧缘几平行,在触角间略膨大,在中眼以下渐向唇基扩大,中央纵沟明显。This paper reports a new genus and two new species of grasshoppers from Yunnan and Guizhou. Type specimens are deposited in the Department of Biology, Shanxi Normal University. Chlorophlaeoba longusala sp. nov, (Figs. 1-7 ) The new species is allied to Chlorophlaeoba tonkinensis Ramme, but differs by the head longer than the pronotum;hind margin of pronotum incised in the middle;the elytra of male reaching the top of hind femur;upper keel of hind femur with fine teeth. Length of body. (?)20-21.5;(?)28-31mm. Length of antenna, (?)1.3-13;(?)11-13mm. Length of pronotum. (?) 3-3.5;(?) 5 -6mm. Length of elytra, (?)13-15;(?)16-17mm. Length of hind femur. (?)11-12;(?)15-16mm. Holotype (?), allotype (?), Yunnan, Mengla. 28. IX. 1980, 660M, Zheng Zhemin;paratypes 30 (?),15(?) Yunnan, Mengla, 28-29. IX. 1980. Zheng Zhemin, Lian Zhengmin, Xi Gengsi. Bidentacris gen. nov. Size median. Antennae filiform, extending beyond the hind margin of pro-notum, the length of middle segments larger than the width about 2 times. Frons oblique, frontal ridge flat, with the margins parallel. The median and lateral carinae of vertex distinct, and extending to the occiput. The lateral carinae of pronotum nearly parallel, slightly curved in the middle. The interspace of meso-sternal lobes nearly square, and the metasternal lobes contiguous posteriorly. Elytra developed, not or reaching or reaching beyond the top of hind femora;cubital area of male wider than median area about 1.7-2 times. The inner side of hind femora provided with a row of stridulatory pegs;the tip of lower kneelobes rounded. The inner lower spur of hind tibia longer than upper spur about 1.1-1.5 times. Annal plate of male with the basal lateral margin curved upward, and on each side of lateral margin near the top with a sharp tooth. The new genus is allied to Aulacobothrus I. Bol., but the annal plate of male with the basal lateral margin curved upward, and on each side of lateral margin near the top with a sharp tooth. Type species, Bidentacris guizhouensis sp. nov. Bidenta
