In Dr. Dyar's recent very full and careful List of North American Noctuids, Wash. Cat., pp. 98–247, are a few errors which I would briefly point out in this journal. They have mostly arisen from a neglect of a couple of papers in Can. Ent., and one in Proc. Am. Phil. Soc., 1895, as well as from a two literal following of Prof. Smith's Washington list. With regard to the general sequence of the order adopted, I have given that preferred by myself in these pages, and can only repeat here that the Noctuid series (Lithosia—Noctua) affords a parallel to that of the blues and skippers in the butterflies, and that I should place them below the series Bombyx, Lachneis—Geometra, disturbing as little as possible the older classifications.
