ined and all species accredited to localities within our limits have 

 been included in the list with the proper references. This has 

 proved no inconsiderable part of the compiler's task and has 

 resulted in the addition of many interesting species largely from 

 the labors of Mr. A. R. Grote. 



Except in the case of the more common and widely distrib- 

 uted species the locality or localities of capture have invariably 

 been given, followed by the surname or initials of the collector. 

 The authority has also been affixed to all notes on the life-history 

 or habits of the species, and wherever the occurrence here of a 

 species has already been recorded in print the reference is appen- 

 ded if known to the Author. 



When the publication of this list was first suggested it was 

 the intention of Prof. Kellicott to undertake its compilation, but 

 unfortunately his removal from our city rendered this inconve- 

 nient and the labor of its preparation necessarily devolved on 

 another. Although losing in value by this change of author- 

 ship it is hoped that the list has suffered little in the mere quan- 

 titive enumeration of our species, thanks to the hearty co-opera- 

 tion of our local collectors. The list as here presented enume- 

 rates 773 species representing 336 genera, and includes all the 

 Lepidoptera known to have been captured within our limits with 

 the exception of the families Tortricidae, Tineidae, and Ptero- 

 phoridae, or the Micro-Lepidoptera, our collections of which are 

 still too meagre to warrant their inclusion at the present time. 

 It is hoped a list of these may be published later with such addi- 

 tions as may be made to the present list. 



The Author takes pleasure in recording here a few personal 

 acknowledgements; first of which is his indebtedness to Mr. 

 A. R. Grote to whose kind attentions and personal instructions 

 he owes such measure of success as he may have attained in his 

 entomological studies, and to whom he also owes the determina- 

 tion of most of the material taken by him at Lancaster. He has 

 likewise been placed under deep obligations to the following 

 students of this order for assistance in the determination of 

 material: Prof. J. A. Lintner, Prof. J. B. Smith, Rev. Geo. A. 

 Ilulst, and Prof. D. S. Kellicott. To these and to the local col- 

 lectors before mentioned as well as to all who have assisted him 

 with notes or specimens he wishes to express his sincere thanks.
