38 MR. A. R. WALLACE ON THE PAPILIONIDÆ 
Guinea district that I visited ; nor was it seen during the exploration, a few years ago, by 
a Dutch steamer which visited the part of the coast where the only specimen known was 
said to have been obtained.

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 Linneeus for the female of Priamus only, in the 
10th ed. of the ‘Systema Nature’ (1758). Clerck (in 1759) adopted the name, but sup- 
posed he had found the male in the female of Remus. Linnæus, in Mus. Lud. Ulric. (1764), 
and in the 12th ed. of the ‘Systema Nature’ (1766), adopts this error, so far as re- 
ferring 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.

The females from these localities are always sooty, with the spots and markings on th 
hinder wings of a dull buff-colour even in the freshest specimens. 
a. Local form Bouruensis.— Male : exactly resembles the Amboyna specimens, except 
that the yellow patch is more variable in form and extent. 
Female: nearly black, and with the markings on the lower wings almost as pure and 
deep yellow as in the males : size a little smaller than in the type.
