P. progne and its subspecies oreas and silenus have differentlyshaped gnathos and tegumen, and have blacker undersides of their wings, than have P. gracilis and its subspecies zephyrus.A new subspecies of P. progne is described from the Southern Rockies, characterized by the underside and abdomen structures of progne and oreas, the upperside of P gracilis zephyrus.The new subspecies is uncommon and has only one generation, versus two in zephyrus.Larvae of P progne subspecies eat gooseberry, rarely currant, whereas larvae of P. gracilis subspecies eat currant.An interesting convergence is shown to affect the wing pattern in many species of Polygonia and one species of Asterocampa, which deserves further study.A synopsis of Nearctic Polygonia is given.
