what buff in color with darker bands near the edge of the wings, which themselves are pinkish on the outside, and with a large clear spot near the centre of the forewing and a regular eyespot (clear in part and blue in the rest) in the centre of the hind wing. One wishing to know about butterflies and moths should consult a book entitled, "How to Know the Butterflies," by Prof. J. H. Comstock of Cornell Univeristy and his wife, Mrs. Comstock, published by D. Appleton & Co., of New York, or, "The Butterfly Book," by Dr. W. J. Holland of Pittsburg, published by Doubleday, Page & Co., .of New York, and "The Moth Book," also by Doctor Holland, and published by the same firm.
Other Insects
There are many more different kinds of insects that there are of flowering plants, and ff we were to add together all of the different kinds of birds, mammals, reptiles, fishes, crabs, mollusks, and all of the lower forms of animal life, they would not all together amount to so many different kinds as there are insects. This makes the classification of insects quite complicated. There are eighteen or nineteen main orders, and each one is subdivided almost indefinitely. There is not one of these that is not full of interest. The habits of ants, for example, living in communities by themselves, afford a tremendous opportunity for interesting observation. A good book about them has been recently written by Dr. W. M. Wheeler, of Harvard, entitled "Ants, their Structure, Development, and Behavior," published by the Columbia University Press, New York.
