The collecting phases of the comprehensive ecological investigations conducted under the auspices of Brigham Young University at the Nevada Test Site in southern Nye County, Nevada, as reported by Allred, Beck and Jorgensen (1963a) yielded relatively few specimens of the beetle families Buprestidae and Cleridae. This is somewhat surprising inasmuch as these groups are usually considered to be major components of the Coleopterous fauna occurring in the desert and adjacent mountainous areas of the southwestern United States. However, several of the collections that were made do provide new or otherwise significant distributional or bionomical information for some of the species encountered. Therefore, a preliminary listing of the species of these two families taken at the Test Site along with a presentation of the available collection information, seems warranted at this time.
