Heffern 10531 Goldfield Lane Houston, TX 77064 Abstract The purpose of this publication is to provide an account of the longhomed beetles of Colorado, to present new distributional records and to bring pertinent literature records together. One hundred ninety-three species and subspecies in 88 genera are listed, including thirty-eight new state records. The overall species distributions and host plants are included to provide an understanding of the zoogeography and possible origins of the species in the state. All available county records are included from the major institutional collections in Colorado, literature records, and numerous private collections. Previous literature citations for species not occurring or unlikely to occur in Colorado are discussed. Hyperplatys montana Casey is considered a valid species and removed from synonymy with H. aspersa (Say). Neoc/ytus ascendens LeConte is considered a synonym of N. leucozonus leucozonus (Castelnau & Gory). Introduction Bowditch, T. D. A. Cockerell and others. All species of Cerambycidae known from Colorado, With an area of 26,998,930 ha (103,922 sq. including thirty-eight species or subspecies not mi.), Colorado is the eighth largest state and previously recorded, are presented here. includes three-quarters of the nation's land above 3,048 rn (10,000 ft). Colorado can be divided into Methods and Materials three distinct natural or physiographic regions (Chronic and Chronic, 1972): the western This paper is the result of the examination of extension of the Great Plains that encompasses Cerambycidae in institutional collections in approximately the eastern 40 percent of Colorado; Colorado, numerous private collections and the Mountain Region that rises abruptly from the extraction of records from literature. The author Plains, and the Plateau Region that gradually examined and identified all of the species that tapers from the mountains to the Utah border. were not previously recorded from Colorado. From the Kansas and Nebraska borders at an Colorado specimens of approximately 80% of the elevation of approximately 1,066 m (3,500 ft), the species recorded from the state in this paper were Plains Region slopes gently upward to the Rocky examined by the author. Most of these specimens Mountains. This area was once comprised are from the two major entomological museums in primarily of shortgrass prairie, but has more Colorado: the C. P.

Unless otherwise noted, all southern portion is used for rangeland. Most of records and label data are from specimens in these Colorado's largest cities and population occupy two museums. Collection codens are included for the western plains along the Front Range of the records which are not from either of these Rocky Mountains. Along the Front Range, the museums.
