The preceding part under this general title was published in 1945 (Can. Ent., 76:217-222). In the present paper I am describing certain species of unusual interest that were collected and sent to me by Messrs. Aitken, Bohart, Degener, Melander and the late Millard C. Vall Duzee, to all of whom I express my sincere thanks and appreciation for this aid. Except where stated to the contrary in the text, the types of the novelties are preserved in my personal collection.
