PREFACE. V 



Grote has been followed. The list in Catocala has been revised 

 by Dr. Hulst. 



The term Geometrina for the single family Geometridce is an 

 addition of my own. The list itself is by Dr. Hulst, and is based 

 upon his published papers in large part. Where he has not 

 studied the species himself Packard is followed, save that the 

 sequence is reversed as in Mr. Grote' s list, with which it also 

 connects in synonymy. 



In the Pyralidina the list is by Dr. Fernald, except in the 

 Phycitid(z and Epipaschiintz for which Dr. Hulst is responsible. 

 Dr. Fernald says as to his part of the list, that it is "only 

 provisional and will undoubtedly be more or less changed upon 

 further study of these insects." It is, however, revisional in 

 character and is based on original study. The synonymy is, 

 therefore, complete in itself. In the Tortricina Dr. Fernald is 

 also authority, and the list connects with his catalogue of 1882. 



In the Tineina Dr. Riley has prepared the entire list. This 

 series is least known among our Lepidopterists, and a vast 

 amount of work is yet to be done. That the list is, therefore, 

 tentative, and in some families scarcely critical can be readily 

 understood. The nature of the case has made some little de- 

 parture from uniformity with the rest of the list desirable, and 

 Dr. Riley in a note at the beginning of the series makes his 

 own explanation. 



The effort has been made to include here all those species 

 dropped from previous lists for want of identification. This 

 may have resulted in a few instances in the resurrection of a 

 synonym or in a duplication of names ; but such errors will be 

 quickly discovered and corrected. 



Finally, I desire to express my sense of obligation to those 

 gentlemen without whose co-operation I could not have prepared 

 this list. Their ready response to my request, in most cases at 

 a considerable inconvenience to themselves, their patience and 

 good nature under urgings and their readiness to adopt the 

 general plan proposed so as to make a uniform work, all demand 

 recognition and gratitude, not only from me, but also from those 

 for whom this list is intended.
