PROCEEDINGS OF THE Entomological Society of Washington Vol. 71 JUNE 1969 No. 2 NEW SPECIES OF CHRYSOBOTHRIS FROM THE PACIFIC NORTHWEST! 2 ( COLEOPTERA : BUPRESTIDAE ) William F. Barr, Department of Entomology, University of Idaho, Moscow, Idaho 83843 ABSTRACT — The new species described are as follows: Chrysobothris horningi from southern Idaho, C westcotti from eastern Oregon, C. potcntillae from west central Oregon, C. idahoensis from southern Idaho, C. breviloboides from south-ern Idaho, C. beeri from western Oregon and southcentral Washington and C. Columbiana from southeastern British Columbia and eastern Washington. Detailed studies of the Buprestidae in the region encompassing the states of Idaho, Oregon and Washington and the province of British Columbia preparatory to a presentation of the species in the final volume of Hatch's "Coleoptera of the Pacific Northwest" has resulted in the discovery of a number of previously undescribed species. Seven such species belonging to the genus Chrysobothris Eschscholtz are described herein in order that their names may become immediately available. Many individuals have offered specimens for study for which I am very grateful. I am especially indebted to F. M. Beer, Oregon State University; M. H. Hatch, University of Washington; D. S. Horning, Jr., University of California, Davis; M. T. James, Washington State Uni-versity; H. B. Leech, California Academy of Sciences; and R. L. West-cott, Oregon Department of Agriculture, for their cooperation and assistance. Chrysobothris horningi Barr, n. sp.
