THE BUTTERFLY GUIDE

By Dr. W. J. HOLLAND
Author of “The Butterfly Book,” “The Moth Book,” Etc. Similar to the “Pocket Nature Guides”

This is the first Butterfly Book of pocket size giving each species in its natural colors. It is uniform in style and binding to the popular Pocket Nature Guides series, and makes a valuable companion volume to these books.

Dr. Holland, Director of the Carnegie Museum, Pittsburg, is the greatest butterfly authority in the country, and has had more experience in the mounting and artistic posing of moths and butterflies than any other living man. The plates in the Pocket Guide are entirely new and reproduced by a special process under Dr. Holland’s personal supervision, from specimens in his own collection.

This book is the most authoritative and valuable guide for field use ever published. It makes the identification of our common butterflies a simple matter for amateurs.

Illustrations of 250 butterflies in their natural colors.

Index. Boxed. Flexible Linen, net, $1.00; Full Limp Leather, net, $1.25
