NOTES ON THE DISTRIBUTION AND BIONOMICS OF SOME IDAHO CERAMBYCIDAE (COLEOPTERA)i William F. Barr and Richard L. Penrose-Distributional and bionomical information concerning some species of Idaho Cerambycidae, especially those associated with range-land shrubs, has been accumulated over the past several years pri-marily during the course of field studies. Although fragmentary in scope, the more pertinent of this information is presented at this time for use by other workers. Representatives of each species treated in this paper are deposited in the University of Idaho insect collections. Thanks is given to J. A. Chemsak and E. G. Linsley, University of California, and J. N. Knull, Ohio State University, for their assis-ance in the determination of some specimens. Ammanus vittigera LeConte Linsley (1962) recorded the known northern limits of the dis-tributional range of this southwestern species as southern Utah. Two specimens have been taken in southwestern Idaho. One was associated with a stand of Atriplex canescens (Pursh) Nutt. four miles southeast of Grandview, Owyhee County. June 20, 1959 (W. F. Barr), and the other was collected from the foliage of A. confertifolia (Torr. & Frem.) Wats, eight miles northwest of Walters Ferry, Canyon County, June 15, 1961 (J. E. Henry). Asemum caseyi Linsley This species known previously from the Pacific Coast region is recorded from Idaho for the first time on the basis of specimens col-lected at Hot Springs, nine miles north of Mountain Home. Elmore County, June 16, 1957 (W. F. Barr) and Pollock, Idaho County, June 7, 1956 (R. W. Portman). Asemum nitidum LeConte This common Pacific Coast species has not been recorded pre-viously from Idaho. Collection records from the state are: Craters of the Moon National Mommient, Butte County, July 15, 1964 (D.S. Horning. Jr.), on Pinus flexilis James, Moscow, Latah County, August 28, 1954 (W. F. Barr); and Troy, Latah County, August 30, 1954 (R. H. Abbott). ^Published with the approval of tlie Director of the Agricultural Experiment Station as research paper no. 7+6. ^University of Idaho, Moscow, Idaho.
