2 WILLIAM G. DIETZ, M. D. 



transcripts made from publications not in my possession. To Mr. 

 W. D. Kearfott I am indebted for some very interesting material. 



Dr. Dyar in his most valuable "List of North American Lepi- 

 doptera, etc.,"* has given a complete index to the literature of the 

 genera and species described up to the time of its publication. I 

 shall therefore simply refer to this list, giving page and number of 

 species. The only exception to this are three species described by 

 Mr. A. Busck since the publication of Dr. Dyar's work. 



To claim that this paper shall be exhaustive of the subject would 

 be ludicrous, that it be free from error, worse than folly. I have 

 endeavored to clear the way to some extent at least of the many 

 difficulties to be encountered by the student of this division of our 

 North American Micro-lepidoptera. 



Passing now from these introductory remarks, I shall briefly indi- 

 cate the limitation of the subject treated of. This is practically 

 included in the family Tineidse of Prof. J. B. Smith's List of Lepi- 

 doptera of North America, edited 1901, to which must be added the 

 genus Amydria Clem., which for some unaccountable reason is there 

 placed among the Gelechhkc. However, while the genera in this 

 as well as in subsequent lists, are placed side by side, without further 

 systematic arrangement, the recognition of a character, apparently 

 overlooked heretofore, has necessitated the division into two sub- 

 families of the large family Tineidse, as defined by Mr. E. Mey- 

 rick,"j" and generally accepted by entomologists here and abroad. 

 These two subfamilies are distinct and sharply defined and one of 

 these, the Amydriinse, owing to the more or less distinct furcation 

 of vein lb of the hindwings, should follow immediately after the 

 Tortricina. Among the Tineinae, this character occurs only — as far 

 as I know — in Breckenridgia and is accompanied by vein le being 

 present. 



The two subfamilies are thus characterized as follows: 



Head rough-haired or almost entirely smooth-scaled. Tongue and maxillary 

 palpi rudimentary. Labial palpi strongly developed, porrect and 

 inure or less ascending, second joint with a brush, more or less de- 

 veloped, or simply thickened with scales beneath, terminal joint 

 pointed, erect, or rarely {Apreta) obtuse and depressed. Vein 7 of 

 forewing to costa or rarely to apex, 16 furcate at base. Hindwings 

 as wide as the forewings, vein lb more or less distinctly furcate at 

 base, le always distinct Amydriiuse.
