Part I. NYMPHALES. 



The following list has been prepared to exhibit in tlie briefest 

 possible manner the classilication, nomenclatnre, geographical dis- 

 tribution and larval food of North American Butterflies. It is the 

 prodromus of a more extended catalogue in which the writer hopes 

 to include a fuller synonymy and especially a complete index of 

 illustrations, and which, through the co-operation of his colleague, 

 IVIr, K. E. Grote, Avill embrace all the Lepidoptera of North America. 

 Complete references, however, are given here to Abbot and Smith's 

 Insects of Georgia, Boisduval and Le Conte's Lepidopteres de 1'- 

 Ameriqne septentrionale. Say's American Entomology and Edward's 

 Butterflies of North America ; a few brief notes are added where it 

 seems desirable, but the aim has been to eliminate everything un- 

 essential to the points in view. For the readier determination of 

 the genera, analytical tables have been prefixed to each ftimily. 



The species are printed in bold faced type and, Avhere they are 

 polymorphic, the names which slionld be employed for the different 

 forms are given in capitals, the synonyms in italics. The generic 

 name of each reference always follows it in parenthesis, nnless the 

 species is referred by the author to the same genus as it is in the 

 list; in such case, the generic name is omitted. 



Species not seen by the writer from the region included in the 

 list, or unknown by illustrations from the same are prefixed by an 

 asterisk. 



My thanks are especially due to Mr. W. H. Edwards, who has 

 given me every possible facility for studying the butterflies of his 

 unrivalled collection, without which the list would have been much
