CHRYSOPHANUS THOK OF GRAY – WHY IS IT NOT C. HYLLUS, CRAMER?

Extract

In my Catalogue of Fabrician Diurnal Lepidoptera, p. 173, I (in 1869) unhesitatingly identified examples of a Chrysophanus in the British Museum collection with Cramer's Papilio hyllus, and at the present time I do not see the slightest valid reason for altering that decision.

In his “Butterflies of the Eastern United States,” Dr. Scudder, at the end of his synonomy of Chrysophanus thoe, says, “Not Papilio hyllus, Cram.”; but, in his account of the species, I find no reason adduced for this assumption, though I can readily believe that the incorrect locality, “Smyrna,” given by Cramer, and the somewhat careless drawing of the spots across the disk of primaries, may have influenced him.
