The Synopsis of North American Butterflies which accompanied Volume I. 

 was issued in 1872, and for various reasons, among them the imperfect knowl- 

 edge of many of the species described and of their distribution, which I shared 

 with the other lepidopterists of the country, it was much at fault. In 18^74, I 

 published in the Transactions of the American Entomological Society a Catalogue 

 of the Diurnal Lepidoptera of America, north of Mexico, which was unquestion- 

 ably an advance upon the Synopsis. In the intervening years many supposed 

 species had been found to be synonymous, and many others to have been erro- 

 neously credited to our fauna. Corrections were made accordingly. The ge- 

 neric names were somewhat changed, and most of those in the Hesperidae dropped. 

 A revised edition of the Catalogue has recently been printed in Volume XI. of 

 the Transactions spoken of, lS§4>^with extended references, and in all respects 

 as complete as I am able to make it. The present List follows the revised Cata- 

 logue, and the numbers of the species in the two cori'espond. The List gives no 

 synonyms, but simply the names of species and varieties. For information 

 beyond that I refer to the Catalogue, which may be had separately on applica- 

 tion to Mr. E. T. Cressox, Post-office Box 1577, Philadelphia, Pa.
