Three news species collected from Yunnan are described. Specimens of the new species are kept in the Institute of Zoology, Academia Sinica, Beijing and Yunnan Control and Quarantine Station of Forest Diseases and Insect Pests respectively.1. Dendrolimus evelyniana Hou et Wang, sp. nov.

Three transverse lines invisible.Exp. 52-53mm 76mm Length 21-24mm 29mm This new species ( ) is somewhat allied to D. serious Lajqnquiere, but differs from the known Dendrolimus spp. in the following respects: 1) The genitalia are markedly very different as shown in Figs. 6-8 aedeagus short, densely scattered with slender spines about 1 / 2 of the whole surface, minor harpe of male genitalia approaching to 1 / 5 the length of the major. The female genitalia are strongly chitinized with mid-antevaginalis oblong and latero-antevaginalis nearly triangular with 3 longitudinal ridges. 2) Reddish-brown, primaries and secondaries without discocellular spot and line. 3) Keteleeria everyniana Mast is the hostplant.Holotype , allotype , paratypes 3 , 2, all these specimens are collected from Lufeng (102.05 ° E, 1800m) Yunnan province. 25-V-1987 by Wang Yongxian.2.Trichiura sanwenensis Hou et Wang, sp. nov.

Primaries with three lines, white discocellular spot indistinct, veins yellowish brown, very distinct. Secondaries light brown, with deep brown band. The posterior margin of 8th sternite with hollow.Exp. 39-40mm. Length 17-18mm.This species is very close to Trichiura khasiana Moore in appearance, but may be distinguished from it by the following characters: 1) prothorax with deep yellow thick scales and some fringes. 2) submarginal line strongly curved, and genitalia very different as shown in Figs 11.3) secondaries with dark brown band.Holotype , paratype , all these specimens are collected from Zhenyuan (23.9 ° N, 100.9 ° E, 2750m) Yunnan province. 15-Ⅶ-1984 by Shen Chenren.3.Gastropacha yunxianensis Hou et Wang, sp. nov. (Figs. 3-4,13-14) Brown, antennae yellowish-brown, head, prothorax deep brown. Primaries with distinct black discocellular spot, apex and hind portion with black mark. Secondaries deep brown with the basal area lighter yellowish-brown, a large light yellowish discocellular spot being present with 2 small black spots on it. Genitalia highly chitinized, aedeagus double-sticked, tarsal clasper with 7-8 teeth at the apical end. Brown. Primaries oblong-triangular with many black scales, black discocellular spot small but distinct, with a black brown mark at the hind angle. Secondaries brown, the basal area lighter.Exp. 27-29mm 31-33mm Length 20-21mm 22-24mmIt is allied to G. pardale sinensis Tams, but smaller in size and male genitalia very different as shown in Figs. 13-14.Holotype S , Yangbi (25.7° N, 100° E, 1700m) Yunnan, 10-Ⅶ-1980, allotype , paratypes 3 ,1 Yunxian (24.5 ° N, 100.1° E, 1100m) Yunnan, 10-20-Ⅶ-1980; 1 , Yunlong (25.9° N, 99.3 ° E, 1500m) Yunnan, 22-VI-1980.
