Abstract

Group VI of North American Ips contains I. perturbatus (Eichhoff), I. hunteri Swaine, I. utahensis Wood and I. woodi Thatcher. A key and descriptions of species are given. Members of this group have the third declivital spine capitate with the tip conical and acute. The front of the head is evenly convex except in females of I. utahensis which have the lower part of the frons faintly elevated. I. woodi breeds in pine while the other three species breed in spruce.
