Abstract
Ips concinnus (Mannerheim) and Ips mexicanus (Hopkins) comprise Group I of the genus Ips DeGeer (Coleoptera: Scolytidae). Members of this group have 3 spines on each lateral margin of the declivity and strongly arcuate sutures on the anterior face of the antennal club. I. radiatae Hopkins is placed as a synonym of I. mexicanus (Hopkins). I. concinnus breeds in Picea sitchensis in the coastal region from Alaska to southern Oregon. I. mexicanus breeds in various species of pines from Alaska to Guatemala and eastward in the United States and Canada to the Rocky Mountains. A key to the species and descriptions are provided.Keywords
