An inLroduction, for the young st~lclent. lo the names and something of the relationship and 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- duslrioiis collector in a course of" a year's 01- two year's work in our Northern States ei-ist of the Great Plains, and in Canada. While all the apparatus necessary to identify these butterflies, in their earlier as well as perf& stage, is supplied, it is fa- from the author's puipose to treat them as if they wereso many mere postage-stamps to be classified find 81.. ranged in a cabinet. He has accordingly
added to the descriptions of the different spe- cies, their most obvious stage&, some of the curious facts concerning their periodicity and their habits of life.

In this book tlie author has tried to present in untechnical language the story of the life of one of our most conspicuous American
b~ittcrflies. At Llie same time, by introduc- ing into the account of its anatomy, devel- opment, distribution, enemies, and seasonal cli~inges some comparisons with the more or less dissimilar stritrture and life of other but- terflics, and particuliirly of our native forms, lie has endeavored to give, in some fashion and in brief space, ;i general account of the lives of the whole tribe. By using a single butterfly as a special text, one may discourse at pleasure of inany: and in the limited field which our native butterflies cover, this meth- od has a certain advantage from its simplicity and dii-ectness.
