An introduction, for the young student, to 

 the nauies and something of the relationship 

 und lives of our commoner butterflies. The 

 author has selected for treatment the butter- 

 flies, less than one hundred in number, which 

 would be almost surely met with by an in- 

 dustrious collector in a course of a year's or 

 two year's work in our Northern States east 

 of the Great Plains, and in Canada. While 

 all the apparatus necessary to identify these 

 butterflies, in their earlier as well as perfect 

 stage, is supplied, it is far from the author's 

 puipose to treat them as if they were so many 

 mere postage-stamps to be classified and ar- 

 ranged in a cabinet. He has accordingly 

 added to the descriptions of the diff'erent spe- 

 cies, their most obvious stages, some of the 

 curious facts concerning their periodicity and 

 their habits of life.

In this book the author has tried to present 

 in untechuical language the story of the life 

 of one of our most conspicuous Ameiican 

 butterflies. At the same time, bv introduc- 

 ing into the account of its anatomy, devel- 

 opment, distribution , enemies, and seasonal 

 changes some comparisons with the more or 

 less dissimilar structure and life of other but- 

 terflies, and particularly of our native forms, 

 he has endeavored to give, in some fashion 

 and in brief space, a general account of the 

 lives of the whole tribe. Bv using a single 

 butterflv as a special text, one may discoinse 

 at pleasure of many • and in the limited field 

 which our native butterflies cover, this meth- 

 od has a certain advantage from its simplicity 

 and directness.
