"A BUTTERFLY BOOK OF BEAUTY." 



How to Know the Butterflies. 



By John Henry Comstock, Professor of Ento- 

 mology in Cornell University, and Anna Botsford 

 Comstock, Lecturer in Nature Study in Cornell 

 University. With 45 full-page colored plates, and 

 many illustrations in the text. 8vo. Cloth, $2.25 

 net ; postage additional. 



This book is designed as a general treatise on butterflies 

 and a manual of the species of the United States east of the 

 Rocky Mountains. It is intended especially for beginners 

 and for students of nature ; but it will also serve as an in- 

 troduction to a serious study of this group of insects. This 

 book is richly illustrated, without a confusing array of figures 

 of species from remote parts of our country; it contains 

 brief descriptions of species, but sufficiently full that the 

 reader can definitely determine the species studied ; and it 

 gives the more important facts of the lives of our butterflies. 



" This book gives the unscientific reader a direct acquaintance with a 

 large number of species, in such simple terms that classification is not 

 difficult, and with the aid of profuse colored illustrations that excite the 

 admiration of those who have contented themselves heretofore with view- 

 ing these beautiful creatures on the wing. Butterfly catching is regarded 

 by many as a cruel pastime, but there are ways of capturing these ephem- 

 erals which may rightly be regarded as humane and decent, and the 

 authors, filled with an abounding love of nature, recommend nothing that 

 is not compatible with their beliefs. Notes of the habitat of each species 

 and the facts of butterfly life are given abundantly, and, with the pictures, 

 form an unusually important book, which is certain to widen the circle of 

 those who know the joys of butterfly collecting."— The Washington Star, 



" Such blending of tints would seem to be a task fit for the painter 

 only instead of the printer. Investigation reveals the fact that the work 

 i=i a veritable treasure-house of information — perhaps the most carefully 

 prepared volume yet placed before the public dealing with the subject in 

 hand." — St. Louis Globe-Democrat. 



" One of the most interesting, valuable, and beautiful of all the nature 

 books published this spring." — Brooklyn Standard- Union.
