Very instructive tables may be prepared of the different expression of European and American genera of moths We have, for instance, more than double the number of species found in Europe of the genera Apafe/a, Oncocnemis, Catocala, etc In fact, going parallel with our larger terri- Moths represented on either side of the Atlantic contain a larger number of American than of European forms and this with but few exceptions, such as Eupethecia, where the American tory, the principal genera of all species are probably but indifferently known Certain genera, very largely represented in Europe in the Moths just as in the Butterflies, are totally wanting in America, as, for instance, Zygaena I am speaking now of peculiar genera which give a determinative expression to the faunae, leav- ing out of sight the innumerable cases of nearly allied genera replacing each other on the two hemispheres comparisons will The time for the institution of such not fully come until our Western faunae are well known So important an European genus as Hypopta has only been recently discovered in Arizona, and undoubtedly we have yet much to learn before we Quite unexpectedly know what forms our territory harbors Snow found in New Mexico a species, Halisidota trigona Grote, really Prof which has an exceedingly close ally in South America, figured by Dr But what was to me a most surprising fact was the Herrich-Schaeffer discovery, by Mr W W Hill, of Albany, N Y., of Hepialus auratus This species belongs to the genus or subGrote in the North Woods genus Phisiodes of Herrich-Schaeffer, and our species has a near ally in That such a genus as Hepialus Brazil as illustrated by this authority should be so widely distributed, considering habits, is its life history, structure a proof of the great age of this type of the Moths and Other Bom- Moths would seem somewhat unwieldy flight and nocturnal habit, not H auratus has patches of dead gold scales prin- bycidae might easily spread themselves, but the Ghost by their to be of weak this structure, number cipally about the cell of primaries at base, while three bright, gilded, tri- I THE CANADIAN ENTOMOLOGIST 239 angular, superposed, brown-edged spots form part of the subterminal opposite the The hind wings cell are pinkish fuscous band both wings have ; Almost all the Hepialin
