4 Boy Scouts are two generations in the Southern states, and one 'in the Northern states. The moth which comes out of the cocoon has a wing spread of fully five inches. It is reddish-gray or some- 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 a?d a regular eyespot (clear in part and blue in the rest)'in the cen- tre 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 Cor- nell 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, a?d "The ?VIoth Book," also by Doctor Holland, Caterpillar to chry?l?s and published by the s?me firm. Other Insects There are many more different kinds of insects tha? 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 ?ll together amount to so many different kinds as there are insects. This makes the classification of insects quite com- plicated. There are eighteen or nineteen main orders, a?d each one is subdiv/ded almost indefinitely. There is not one of these that is not full of interest. The habits of ants, for ex- ample, living in communities by themselves, afford a tremend- ous opportunity for interesting observation. A good book about them has been recently written by Dr. W. M. Wheeler, of Harvard, entified "Ants, their Structure, Development, and Behavior," published by the Columbia/oh?iy?e?/ty Press, New York.
