Abstract

Group IX of North American Ips contains I. grandicollis (Eichhoff), I. confusus (Leconte), I. montanus (Eichhoff), I. cribricollis (Eichhoff) and I. lecontei Swaine. I. chagnoni Swaine is made a synonym of I. grandicollis (Eichhoff). Ips of Group IX differ from other Ips by having five spines on each side of the elytral declivity. Species are described and a key is given. They breed in various species of Pinus and most of them occur south of the boreal forest.
