It occurs on Long Island, in New York, New Jersey,Pennsylvania, Delaware, Maryland, District of Columbia, Vir-ginia, West Virginia, North Carolina, Tennessee, Georgia, Ohio,Kentucky, Indiana, Illinois, Michigan, and Wisconsin. BroodVII., of the thirteen-year race, and Brood XXII., of the seventeen-year race, come in contact in Southern Illinois and NorthernGeorgia, and it may happen, as it did in 1885, that these twobroods appear during the same year at the same place. 10 146 AN ECONOMIC Fulgoridce, or lantern-flies.—a Scolops,sulcipes; b, Pceciloptera truncaticornis:twice natural size.
