PREFACE 7 



Edwards's " New Catalogue of the Butterflies of North 

 America" has been followed. 



It has been suggested that I should give, in addition 

 to the table for tracing species to their description, a table 

 of larvse. In my opinion our present knowledge is not 

 sufficient to make a satisfactory one. Though much is 

 known of the preparatory stages of our butterflies, there 

 are still too many gaps : these, however, are being filled 

 up, so that in a few years a table can be given that will 

 be more satisfactory than any that could be prepared 

 now.

PREFACE TO THIRD EDITION. 



In an addenda to the second edition of " Butterflies 

 of the Eastern United States" three species were added 

 that were not known to occur here when the first edition 

 was published,-^ Colcenis Delila, Nconympha Mitchellli, 

 and Pampkila Aaroni. These were referred to their 

 appropriate places in the body of the work by number 

 and the number of the pages. Since the publication of 

 the second edition seven species and four varieties have 

 been found in the territory covered by this work that 

 were not known to exist there before. Five of the 

 species and three of the varieties were new to science, 

 having been described since 1890, and the others have 

 wandered from their former known habitats.
