to me undetermined material, and by freely communicating to me 

 their notes and observations. My sincere thanks are jointly extended 

 to them for their courtesy. I am under special obligations to Dr. H. 

 G. Dyar, Professor John B. Smith, Mr. August Busck, and Mr. W. D. 

 Kearfott for their kind assistance in determining numerous species for 

 me. Dr. W. J. Holland has accorded to the list his editorial super- 

 vision, and has added here and there the names of species known to 

 him as occurring in the region, and has here and there appended notes. 

 I have followed the nomenclature and order given in " A List of the 

 North American Lepidoptera, " published by Dr. H. G. Dyar, as 

 "Bulletin No. 52 of the United States National Museum." I have 

 departed in some places from that List, especially in the case of the 

 Micro-lepidoptera, where these have been studied and revised by 

 authors who have published since Dr. Dyar gave his List to the world. 

 This is more particularly true in the case of the Tineidce, upon which 

 Messrs. Dietz and Busck have recently published extensively. The 

 rapid increase in our knowledge of the subject very soon causes the 

 best list to become antiquated.'

 typographical errors which are found in that publication, to which it may not be im- 

 proper to call attention. I only cite those which relate to the following list.
