The present paper deals with four species of the genus Gergithoides Schumach er, of which two are new to science, i.e., Gergithoides undulates Wang et Che, sp. nov. and Gergithoides gibbosus Chou et Wang, sp. nov. New species are described and illustrated.A key to all species of this genus is pr oposed. The type specimens are despoisted in the Entomological Museum, Northwest Sci Tech University of Agriculture and Forestry. 1. Gergithoides carinatifrons Schumacher Specimens examined: 1♂2♀♀, Jianfeng Mountain, Hainan Province, 14 Ⅻ 1974, coll. Yang Chikun;1♂, Jianfeng Mountain, Hainan Province, 30 Ⅺ 1981, coll. Liu Yuanfu; 1♀, Jianfeng Mountain, Hain an Province, 22 Ⅶ 1982, coll. Liu Yuanfu. 2. Gerithoides rugulosus Melichar Specimens examined: 1♂, Wuyi Mountain, Fujian Province, 30 Ⅶ 1984, coll. Cui Zhixin; 1♂, Sangang, Fujian Province, 02 Ⅹ 19 81, coll. Jiang Fan; 1♀, Daming Mountain, Wuming, Guangxi Zhuang Autonomous Region, 24 Ⅴ 1963, coll. Yang Chikun;1♀, Qingcheng Moutain, Sichuan Province, 12 Ⅷ 1957, coll. Zheng Leyi ;1♀, Guantai, Qiube i, Yunnan Province, 27 Ⅵ 1979, coll. Liao Qiyu. 3. Gergithoides undulatus Wang et Che, sp. nov. (Figs.1～ 6) Length (incl. Teg.): ♂6.0 mm, ♀6.2 mm; Tegmen: ♂4.6 mm, ♀4.9 mm. This species is similar to G. rugulosus , but can be separated from the latte r by: 1) legs yellow brown, coxa and the base of femora of fore and middle legs black, hind femora black, but in the latter, coxa dirty green, femora with brown stripes; 2) tegmen without mark, but in the latter with white mark; 3) in dorsa l view, the shape of anal segment likes the head of a wolf, lateroapical angles obviously rise, but in the latter, apical margin straight, the shape likes a cup . Holotype ♂, Xiandi, Rong county, Guangxi Zhuang Autonomous Regio n, 08 Ⅶ 1981, coll. Luo Guibiao. Paratypes 1♀, Jianfeng Mountain, H ainan Province, 1412 m, 27 Ⅶ 1983, coll. He Jianli; 1♀, Jianfeng Mount ain, Hainan Province, 01 Ⅷ 1983, coll. Hua Lizhong; 1♀, Jianf eng Mountain, Hainan Province, 26 Ⅱ 1982, coll. Chen Zhen yao ; 1♀, Jianfeng Mountain, Hainan Province, 24 Ⅺ 1981, coll. He C hongbin; 2♀♀, same locality, date and collector as holotype; 1♀, Dali, Putuo, Yulin, Guangxi Zhuang Autonomous Region, 31 Ⅶ 1980, coll. He Yandong; 2♀♀, Jianfeng Mountain, Hainan Province, 23 Ⅹ 1981, 20 Ⅵ 1981, coll. Gu Maobin;1 ♀, Jianfeng Mountain, Hainan Pro vince, 24 Ⅻ 1981, coll. Liu Yuanfu. 4. Gergithoides gibbosus Chou et Wang, sp. nov. (Figs.7 ～13) Length (incl. Teg.): ♂5.5 mm,♀6.0 mm; Tegmen: ♂4.4 mm, ♀5.1 mm. This species resembles G.carinatifrons , but can be distinguished from th e latter: 1) tegmen pale brown with black mark, but in the latter dark brown wit h pale yellow mark; 2) in dorsal view, the shape of anal segment likes the head of a bear, lateroapical angles obviously rise, but in the latter, apical margin shallowly rise; 3) aedeagus with W shaped processes, but in the latter with S shaped processes.
