The paper deals with thirteen species of the genus Kolla Distant from China,of which three are new to science: K.pentistigma sp.nov., K.nigrifascia sp.nov.,and K.rhabdoma sp.nov..A key to species is given.The type specimens are deposited in Institute of Entomology,Guizhou University. Kolla pentistigma sp.nov. (Figs.1～6) This species is similar to Kolla polita (Walker,1857),but its crown with five black spots,scutellum orange with a basal triangular black stripe on each side,male connective extending posteriorly beyond style apices,and the shape of aedeagus is also different. Body length (incl. tegm.):♂ 6 0?mm,♀ 6 2?mm. Holotype ♂,Guizhou Province:Fanjing Mt.(1 000～1 200 m),July 22,1986,coll.by LI Zi\|zhong.Paratype 1♀,same data as holotype. Kolla nigrifascia sp.nov.(Figs.7～16) The new species is related to Kolla pentistigma sp.nov.,but differs from the latter in:crown with different colour pattern;face with a longitudinal black stripe;thorax beneath with black spots;male aedeagus with shaft broader,and process between shaft narrower than them. Body length (incl.tegm.):♂5 5～6 5 mm,♀6 0～6 8 mm. Holotype ♂,Guizhou Province:Libo County,September 27,1996,coll.by YANG Mao\|fa.Paratypes 6♂♂,1♀,same locality as holotype,October 15～16,1988,2♂♂,5♀♀,Shiqian County,August 14～16,1994,2♂♂,8♀♀,Daozhen County,September 14,1988,3♂♂,11♀♀,Shuicheng,August 22～27,1986,5♂♂,7♀♀,Pan County,July 29,1985,1♂,Rongjiang County,August 13,1989,3♂♂,1♀,Sandu County,October 24～27,2♂♂,1♀,Fanjing Mt.,July 22,1986,2♂♂,Guiyang,June 28,1977,2♂♂,Suiyang County,August 2,1984,4♂♂,2♀♀,Wangmo County,June 27,1986,coll.by LI Zi\|zhong;7♂♂,8♀♀,Ziyun County,July 23～24,1996,5♂♂,2♀♀,Sichuan Province:Emei Mt.,July 13～14,1995,YANG Mao\|fa's collections;8♂♂,2♀♀,Yunnan Province:Lijiang County,May 28,1996,coll.by Du Yu\|zhou. Kolla rhabdoma sp.nov.(Figs.17～25) This new species is closely related to Kolla insignis Distant,1907,but can be distinguished from the latter by face with a longitudinal black stripe,scutellum with different colour pattern,male aedeagus with shaft spine\|like process on outer margin at end,process between shaft small stick\|like. Body length(incl.tegm.):♂5 5～6 1 mm,♀5 7～6 4 mm.
