(11) =Chrysophanus snowi=, Edwards, Plate XXIX, Fig. 7, ♂; Fig. 8, ♀ (Snow's Copper). _Butterfly._--This is a medium-sized species, easily recognized by the even, rather wide black border on both wings on the upper side, and the dirty-gray color of the hind wings on the under side. Expanse, 1.15-1.25 inch. _Early Stages._--Unknown. Snow's Copper, which is named in honor of the amiable Chancellor of the University of Kansas, occurs in Colorado at high elevations, and is reported from Alberta and British Columbia. (12) =Chrysophanus rubidus=, Behr, Plate XXIX, Fig. 5, ♂; Fig. 6, ♀ (The Ruddy Copper). _Butterfly._--This is a rather large species. The male on the upper side is prevalently pale, lustrous red, with a narrow black marginal band and uniformly conspicuous white fringes. The upper side of the female is accurately depicted in the plate. On the under side the wings are shining white, the secondaries immaculate. Expanse, 1.30-1.50 inch. _Early Stages._--These are altogether unknown. This exceedingly beautiful species is found in Oregon, Nevada, and Montana. (13) =Chrysophanus sirius=, Edwards, Plate XXIX, Fig. 3, ♂; Fig. 4, ♀ (Sirius). _Butterfly._--The male closely resembles the preceding species on the upper side, but is brighter red, especially along the nervules of the fore wings. The female on the upper side is dusky. On the under side the wings are whitish or pale gray, but the hind wings are not without spots, as in the preceding species, and carry the characteristic markings of the genus. Expanse, 1.20-1.30 inch. _Early Stages._--Unknown. The species has been found from Fort McCleod, in British America, as far south as Arizona, among the North American Cordilleras. THE UTILITY OF ENTOMOLOGY All the forces of nature are interdependent. Many plants would not bear seeds or fruit were it not for the activity of insects, which cause the pollen to be deposited upon the pistil and the seed-vessel to be fertilized. Attempts were made many years ago to grow clover in Australia, but the clover did not make seed. All the seed required for planting had to be imported at much expense from Europe. It was finally ascertained that the reason why the clover failed to make seed was because throughout Australia there were no bumblebees. Bumblebees were introduced, and now clover grows luxuriantly in Australia, making seed abundantly; and Australian meats, carried in the cold-storage rooms of great ocean steamers, are used to feed the people of Manila, Hong-Kong, Yokohama, and even London.
