Abstract

Group IV of North American Ips (Hopping 1963a) contains I. avulsus (Eichhoff), I. bonanseai (Hopkins) and I. pini (Say), which breed mainly in pines. They have four spines on each side of the elytral declivity and the elytral interspaces are impunctate except I. bonanseai which occasionally has interspace punctures. A key to the species is given and Ips oregoni (Eichhoff) is made a synonym of Ips pini (Say). Group V has only one species, I. perroti Swaine, the only North American Ips with straight sutures on the antennal club. Data on hosts and distributions are given.
