TRANSACTIONS OF THE AMERICAN ENTOMOLOGICAL SOCIETY. VOLUME XXXI. Revision of the Genera and Species of the Tineid Sub-families Amydriiiue and Tineinse inhabiting North America. BY WILLIAM G. DIKTZ, M.D. The present essay is the result of studies, carried on over a period of about three years, of our North American species of the Micro-lepidopterous family Tineidse in its restricted sense, or more expli-citly stated, in the sense of the older authors, exclusive of the Adelidae and Taliporidse. The pursuit of these suffered many inter-ruptions and encountered not a few difficulties. The former chiefly due to professional duties, the latter: 1st, to the comparatively small number of well authenticated and recognized species among the large number enumerated in our lists and found in collections; 2nd, the descriptions, scattered among various publications, principally periodicals and long out of print, are often defective and leave much to be desired to enable a positive identification of a given species. Fortunately, however, the existence of Dr. Clemen's types in the collection of the American Entomological Society, at the Academy of Natural Sciences, Philadelphia, and a number of the types of Mr. Chambers and several of Prof. Zellers, in the Museum of Com-parative Anatomy, Cambridge, Mass., has enabled me to examine and study these and thus clear up many doubtful points not possi-ble otherwise. In this connection I wish to express my special obli-gation to Prof. Samuel Henshaw of Cambridge, and also to Dr. Henry Skinner of Philadelphia for the courtesy and assistance ex-tended to me on these occasions. I likewise wish to express my deep appreciation to my friend and colaborator, Mr. A. Busck of Washington, D. C, for much valuable advice, loan of material and TRANS. AM. ENT. SOC. XXXI. (1) JANUARY.
