The Second Volume of the "Butterflies of North Amei'ica" will not be 

 strictly confined to the descriptions and delineations of new species. In the 

 Advertisement to the First, I mentioned the fact that the preparatory stages of 

 even our old and common species of butterflies were scarcely better known than in 

 the days of Abbot, well nigh a century ago. But within the past four or five 

 years a great advance has been made in this respect, and what w^is true in 1868 

 is no longer so. Through the labors of a few zealous naturalists, it is now 

 possible to trace from the egg, through successive larval phases to the chrysalis 

 and butterfly, a large number of North American species about which little or 

 nothing was then known. To illustrate some of these changes will, I hope, 

 render this volume both interesting and valuable. 



I am pleased to be able to say that I have the cooperation of Miss Peart and 

 Mrs. Bowen, which is an assurance that the execution of the Plates .shall equal 

 in fidelity and finish those before published. The Plates belonging to each 

 Genus will not always be issued in sequence, as is observable in Part I., but 

 when the close of the Volume is reached, all will be found in proper order. 



With the last Part, a revised Synopsis of Species will be given.
