Barber, Bureau of Entomology and Plant Quarantine, U. S. Department of Agriculture, Wa^shington, D. C. The <ienns Kleidocerys has a "wide distribution throughout the ITolaretie region and extends into the Neotropical region as far south as northern South America. K. rcsedae (Panzer) is an holarctic species; franciscanus (Stal) (=ericae (Hor-vath) probably was introduced on our west coast from Asia. Because of the great similarity among the various species of the genus occurring in the United States there has been much confusion regarding the identity of several of them. K. rescdac gonixafus (Say) is the best known species from southern Canada and much of the eastern and southern states, where it is known to feed on the dried seeds of a number of plants. Of the seven species treated here three are new. Aside from color differences the author has had to rely mainly on proportionate dimensions of body parts for differentiating the si)ecies.
