One new species, Fiorinia nanningensis Zhang ＆ Feng sp. nov. from China, is described and illustrated. The new species is similar to F. linderae Takagi, 1969, with both having gland spines absent on the pygidium, and second lobes reduced, at most represent by a slight prominence, or absent; but differing from the latter in： 1） median lobes of new species small and narrow, without notches, ends often truncated （median lobes large and serrate, pointed apically in E linderae）; 2） gland spines or gland tubercles absent on body （with 1-3 gland tubercles on metathorax and 3 or 4 on abdominal segment I, and 1-2 gland spines on abdominal segment II in E linderae）; 3） interantennal process absent between antennal bases （small and conical in E linderae）. The type specimens are deposited in the Entomological Museum of Northwest A ＆ F University, Yangling, Shaanxi, China （NWAFU）.
Two soft scales, Kilifia deltoides De Lotto, 1965 and K. americana Ben-Dov, 1979 are recorded from Hainan, China for the first time. Detailed descriptions and illustrations of adult females are given. A key to the Chinese species of adult females is provided. The specimens examined are deposited in the Entomological Museum of Northwest A ＆ F University, Yangling, Shaanxi, China （NWAFU）.
Cypress plays an important role in urban afforestation in Tibet of China, and scale insects are a serious pest group that attack Cypress. In this paper, a new species, Lepidosaphes xizangensis Feng, sp. n. from Tibet, is described. Its damages to cypress trees are recorded. The new species is similar to Lepidosaphes pineti Borchsenius, 1958, with its perivulvar disc pores arranging in eight groups, but can be distinguished from the latter by the following characteristics： （1） gland spines between median lobes longer than median lobes; （2） distance between median lobes similar than width of median lobes; （3） dorsal gland ducts are much more slender. It enriches the diversity of Lepidosaphes fauna of China and adds new information of coccids＇ damages to cypress.
A new species of the genus Odonaspis Leonardi,1897（Hemiptera：Coccoidea：Diaspididae） is described and illustrated：Odonaspis longyanensis Wang et Feng,sp.nov..A key to known species of this genus from China is given.
The genus Ericeroides Danzig, 1990 and one species E. zaitzevi Danzig, 1990 of Coccidae are recorded for the first time from Yunnan, China. The new recorded genus is close to Ericerus Gu6rin-M6neville, with both having numerous stigmatic spines and claw denticles, but it can be distigusihed by lacking dorsal tubular ducts and preopercular pores. Detailed descriptions and illustrations of adult female are given in this paper.
