New Synonymy , New Species , and Taxonomic Notes of North American Pityophthorus ( Coleoptera : Scolytidae ) , Part Iii

— New synonymies and new data affecting North American Pityophthortis are proposed as follows: chalcoensis Hopkins { = herrerai Hopkins) and nigricans Blandford ( = chiapensis Bright). Neotypes are designated for the following species described by Eichhoff: concentralis, cribripennis, infans, puchellus, and tuberculatus. New species are: carinatus (Canada), cavatus (Manitoba, Saskatchewan), euterpes (Mexico), hesperius (British Columbia), impexus (Mexico), intentus (Arizona), laticeps (Mexico), rnalleatus (Arizona), mesembria (Guatemala), montezumae (Mexico), scalptus (British Columbia, Colorado), trepidus (California), and vespertinus (Mexico). This is the third paper under this general title wherein various new taxonomic data affecting the classification of the North American Pityophthortis are proposed. A taxonomic monograph of North American Pitijophthorus is being prepared, but the data contained herein is needed for other works in preparation. It was therefore decided to publish these data now in order that they may be used without delay. The collections where type material is located are abbreviated as follows: British Museum (Natural History), London (BMNH); Canadian National Collection of Insects, Ottawa (CNC); Karl E. Schedl collection, Lienz, Austria (KESC); S. L. Wood collection, Provo, Utah (SLWC), and United States National Museum of Natural History, Washington, D.C. (USNM).
