Scudder's Brief Guide to the Com 

 moner Butterflies. 



By Samuel H. Scudder. xi + 206 pp. 

 l2mo. $1.25. 



An introduction, for tlie young student, to 

 ttie names and sometliing 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 bv 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 

 pui pose 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 de,scriptions of the different spe- 

 cies, their most obyious stages, some of the 

 curious facts concerning their periodicitv and 

 tlieir habits of life. 



Scudder's The Life of a Butterfly. 

 A Chapter in Natural History for 

 the General Reader. 



By Samuel H. Scudder. 186 pp. i6mo. 

 $i.oo. 



In this book the author has tried to present 

 in untechnical language the story of the life 

 of one of our most conspicuous American 

 butterflies. At the same time, by 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. By using a single 

 butterfly as a special text, one may discourse 

 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.
