The specimens above quoted agree well with Cramer’s figures. The female from the Sulla Islands differs only in having more yellow towards the anal angle of the lower wings. The specimens figured by Cramer in pls. 10, 11, under the name of “Hypolitus” seem to be a remarkable variety, in which the female has much of the character of the male. Messrs. Doubleday and G. R. Gray have adopted Panthous as the specific name of this insect; but this name was first used by Linnæus for the female of Priamus only, in the 10th ed. of the ‘Systema Naturæ’ (1758). Clerck (in 1759) adopted the name, but supposed he had found the male in the female of Remus. Linnæus, in Mus. Lud. Ulric. (1764), and in the 12th ed. of the ‘Systema Naturæ’ (1766), adopts this error, so far as referring to Clerck’s two figures; but in both these works his description refers only to the female of P. Priamus, indicating that the supposed other sex (P. Remus) was not known to him personally. The name of Panthous must therefore altogether drop, it having been applied to this species only through a double error—first, that of Linnæus, in supposing his Panthous to be distinct from Priamus, and then that of Clerck, in thinking that a female Remus was the male of the Linnean Panthous.
