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
