That section of the genus Itame to which have been assigned the names argillacearia and occiduaria of Packard, modestaria and olivalis of Hulst and andersoni Swett has provoked many a sigh of exasperation among collectors and systematists trying to organize their material. The present paper represents several years of intermittent study and observation, and although no drastic changes in nomenclature or arrangement seem warranted, I shall set forth my conclusions for what they are worth. This may actually be regarded as a supplement to Dr. J. McDunnough's remarks on the group in a paper of 1924 (Notes on the Ribearia Group of the Genus Itame. Can. Ent., Vol. 56, p. 271), additional material having been examined that was not available to him at that time.
