摘　　要：山西地形狭长,南部和东南部可渗入东洋区昆虫,北部与内蒙古接壤,有来自东北亚西伯利亚,中亚细亚,甚至远源地中海成员,所以蚧类区系应该是丰富的。然而解放前调查研究工作做得很少,正式记录不超过10种,其中有美国的C.L.Marlatt,约在1901年深入山西调查梨园蚧 Quadraspidiotus perniciosus(Comst.)。In the course of study on the fauna of Coccoidea,Homoptera,in Shanxi Province,we found three species new to science and one genus new record to China.All type specimens are deposited in the University's Coccoidea Collection.1. Rhizaspidiotus taiyuensis sp.nov.(fig.1)Adult female mounted on slide about 0.63-0.81 mm long and 0.57-0.70 mm wide,derm membranous except for the pygidium weakly sderotized.Perivulvar pores;(8-9)7-10,scale of female convex and ventral scale formed white in color,with exuviae yellowish and central in position;of male elongate but similar in texture and color to the female'sMaterial examined:Holotype,Paratypes 4 and all larval stages collected from Taiyue Mountain in Shanxi,Aug.19,1985 on Artemisia argyii by Guang-lu Shi.The new species is distinguished from others of this genus by ordinarily and stably developed the fourth and fifth lobes on the pygidium which fully with plates present the bifurcare or chelate appearance.2.Tsugaspidiotus piceae sp.nov.(fig.2)The genus is for the first time recorded to China.Material found on the needles of Picea asparata at Ningwu County,May 14,July 25,1985 and Shuimen Village,VII 25 and 30,1985,represents a new species.Material mounted on slides includes different developmental stages.The 2nd stage female(fig.2c)about 0.54-0.56 mm in length ovoid in shape.The adult female just moulted pyriform in shape(fig.2b),about 0.60-0.65mm long,but when fully developed and pregnant,body composed mostly of the enlarged membranous prepygidial portion like a bag,then the pygidium becomes quite small and sunken into the body,by this time the whole expanded body length about 0.95-1.00mm(fig.2a).The two periods are very similar to each other morphologically except that the interscgmental marginal scleroses are weak and faint in the young period but obvious in the pregnant period as illustrated in the accompanying figures The perivulvar pores of two periods are all variable from 2-5 groups:0-4(2-3)0-3.pygidial lobes are all in 3 pairs,L3 variable even on each side.Thoracic s
