Vol. 35, pp. 95-96 August 30, 1922 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON CHANGES IN NAMES OF AMERICAN RHYNCH(3TA CHIEFLY EMESINAE. BY W. L. McATEE AND J. R. MALLOCH. Owing to the extreme and touching sohcitude of certain of our contemporaries for the taxonomic welfare of groups of Hemiptera recently specialized upon by us, we deem it advis-able to place on record the subjoined changes in nomenclature which otherwise would have been withheld until publication of comprehensive sj^stematic treatises now well advanced. EMESINAE. Barce Uhler = Metapterus Costa. Luteva Dohrn = Ploiaria Scopoli. Ploiariopsis Champion = Ploiaria Scopoli. Ploiaria Carolina Banks not Herrich-Schaffer = Ploiaria hirticornis Banks. Ploiariola Reuter = Ploiariodes White. Ploiariodes californica Banks = Ploiariodes rubromaculata Blackburn. Ploiariodes euryale Kirkaldy = Ploiariodes rubromaculata Blackburn. Ploiaria maculata Haldeman = Ploiariodes culiciformis De Geer. Ploiariodes errahunda Banks not Say = Ploiariodes culiciformis De Geer. Ploiariodes tuberculata Banks = Ploiariodes errabunda Say. Ploiariodes hirtipes Banks = Ploiariodes vagabunda Linnaeus var. pilosa Fieber. Ploiariodes canadensis Parshley = Ploiariodes vagabunda Linnaeus var. pilosa Fieber. Luteva arizonensis Banks is a Stenolemus. Myiagreutes Bergroth is a subgenus of Westermannias Kirkaldy. ISOMETOPIDAE. Isometopus of Am-^rican authors is not Isometopus of Fieber and we pro-pose for it Corticoris new name. Genotype Isometopus pulchellus Heidemann. 19— Proc. Biol. Soc. Wash., Vol. 35, 1922. (95)
