The present paper deals with genus Compsihlon Reuter 1899 from North China. A new species Compsidolon punctulatus sp. nov. is described. C. absinthii (Scott, 1870) is here recorded as new to China, and C; gubicus Nonnaizab 1994 is considered to be a new synonym of Solmxyphus lepidus (Puton, 1874). Type specimens of the new species will be deposited in the Biological Faculty of Inner Mongclia Teachers' University.

The Chinese fauna of the mirid subfamily Isometopinae is examined. Fifteen species of Isometopinae are recorded from China, belonging to the genera Isometopus Fieber, Letaba Hesse, Myiomma Puton, and Sophianus Distant. The known species are reviewed in detail, including their citations, distributions, and host plants. Information about type material and the description of a new species, Myiomma qinlingensissp. nov., are given. Keys to the Chinese genera and species are given.

Two new species and a little‐known one belonging to genus Solenoxyphus Reuter are noted here. Solenoxyphus flavicans sp. nov. and S. viridulus sp. nov. living on Artemisia ssp. are described from Xinjiang, Qinghai and Xinjiang of China respectively; S. lepidus (Puton 1874) on Artemisia ssp. is recorded for the first time from China and redescribed from Xinjiang.
