THE COMMISSION turned next to consider the appUcation (file Z.N.(S.)144) submitted by Dr. W. E. China (British Museum (Natural History), London) in regard to the names of ten genera in the Order Hemiptera (Class Insecta), each of which, it was considered, was based upon a misidentified type species. The applications so submitted sought in each case the use of the plenary powers to designate as the type species of the genus concerned the species originally intended (as contrasted with the species actually cited) by the author of the generic name in question. The applications were the following : — (a) Aquarius Schellenberg, 1800 Gerris paludum Schellenberg, 1800, had been ' selected as the type species of this genus by Kirkaldy, 1906, but it was considered that the species referred to under this name by Schellen-berg was Cimex iiajas De Geer, 1773. The Commission were asked to designate the latter species as the type species of the genus (China, 1947, Bull. zool. Nomencl., 1 : 277-278). (b) Bellocoris Hahn, 1834 Cimex maurus Linnaeus, 1758, had been selected as the type species of this genus by Westwood (1840), but it was considered that the species referred to under this name by Hahn was Cimex austriacus Schrank, 1776. The Commission were asked to designate the latter species as the type species of this genus (China, 1947, Bull. zool. Nomencl, 1 : 278-279). (c) Beosus Amyot & Serville, 1843 This genus was monotypical, the sole species referred thereto by the authors of the generic name being Lygaeus quadratus Fabricius, 1803. It was considered that the citation of this name was due to a misidentification and that the species
