    • 1877, Samuel Hubbard Scudder, Antigeny, Or Sexual Dimorphism in Butterflies, page 151:
      It is a curious circumstance that, while albinic antigeny finds its most complete expression in high temperate regions, and melanic antigeny prevails toward the tropics, the albinic females of a partially antigenic species never appear in the spring brood, but increase in numbers throughout the hot season []
