The preceding part under this title was published in 1945 (Can. Ent., 77:204-208). The species discussed at this time are chiefly from Oregon, where they were collected by my friends, Dr. James A. Macnab and Mr. Kenneth M. Fender, to whom I am indebted for the privilege of retaining the type materials. Dr. Macnab and Mr. Fender are engaged in detailed studies of this most interesting part of the Coast range and already have added vastly to our previous knowledge in many groups of insects.
