* Probably by an error in proof-reading the text on page 39, Papilio, I., reads: “3 females, Prescott, Ariz; 1 male, Dalles, Oregon.” Henry Edwards had no females of this species. In his collection at the Museum of Nat. Hist., New York City are 3 males from Prescott, Ariz., and 1 males from Dalles, Oregon.
