In spite of the great economic importance of north American Scolytidae, many taxonomic descriptions remain inadequate for the identification of species, and existing keys have been made obsolete by the recent description of new species. To bring these keys up to date and make them useful to students and practical foresters, detailed studies of the morphological structure of the various species are necessary. The purpose of the present investigation has been to clarify and revise existing keys and to describe briefly the species of Scolytidae occurring in the Logan Canyon area of Utah. The following keys and descriptions will be of value to students, foresters, and taxonomists in identifying the species of Scolytidae occurring in northern Utah. Information secured in this investigation also contributes toward the geographic and host distributional knowledge of the Scolytidae in Utah.
