PREFACE. 



The last catalogue, that by Mr. W. H. Edwards, was published 

 fourteen years ago, and has been out of print for some time. Since 

 Mr. Edward's catalogue appeared, a number of important works 

 have been published and many magazine articles. Quite a number 

 of species have been described and life histories made known. The 

 more important new works on the Lepidoptera have been " Scudder's 

 Butterflies of the Eastern United States and Canada;" the " Bio- 

 logia Centrali- Americana," and the completion of the third volume 

 of Mr. Edward's "Butterflies of North America." A single line 

 has been devoted to each reference, thus greatly aiding the eye in 

 finding what is wanted. When a species is found outside our faunal 

 limits its entire distribution is given. A few species have been put 

 into the synonymy, but only in cases where it seemed well warranted. 

 No attention has been paid to the genera, as they are in a chaotic 

 state and will require special study by some one taking cognizance 

 of the genera of the world ; therefore the genera remain practically 

 the same as in the Edwards' catalogue. All references of import- 

 ance are included, and it is hoped the catalogue will be found 

 accurate and prove useful. All sources of information were freely 

 taken advantage of, and the compiler must acknowledge his indebt- 

 edness to the catalogues of Morris, Kirby, Scudder, Strecker and 

 Edwards.
