This is a common insect, and has a very extended range; it is included by Smith and 
Abbot in their work on the Lepidopterous insects of Georgia; and our collection 
contains a continuous series of examples from all countries southward to the Argentine 
Republic. Individuals are subject to slight variation: the four black spots within the 
cell of the primaries in some are united so as to form only two, while the number of 
those occupying the discal area of the secondaries varies from one to three; the amount 
also of the black stripes towards the outer margin of the primaries varies; and this 
occurs without reference to locality. This species was named by Linnzus, who, in his 
description, refers to the figures in Clerk’s ‘Icones Insectorum,’ Merian’s ‘ Surinam,’ 
and Sloane’s ‘History of Jamaica.’ Fabricius, referring to the same figures, renames 
the species P. passiflore, doubtless having ascertained the food-plant of the insect; 
and Smith and Abbot follow him in this, remarking that in Georgia D. vanill@ does 
not feed on the Vanilla, but on the Passion-flower (according to Mr. Strecker Passifiora 
cerulea and P. incarnata), as the former plant does not grow there, and therefore 
Linnzeus’s name is not a suitable one. Specimens from Haiti, Cuba, and Jamaica are 
identical with those from the mainland. 
In Guatemala Agraulis vanill@ is found in suitable localities from the sea-level to an 
altitude of about 3000 feet above the sea. 
CLOTHILDA. 
Clothilda, Blanchard, Hist. Nat. Ins. iii. p. 440 (1840); Doubl. Gen. Diurn. Lep. p. 155; Salv. 
Trans. Ent. Soc. 1869, p. 391. . 
With the general appearance of some members of the genus Argynnis, Clothilda 
differs in many important particulars. The chief and most obvious of these is the 
presence of a well-defined discocellular nervule in the secondaries, which completely 
closes the cell of those wings. The first and second branches of the subcostal nervure 
of the primaries are thrown off before the end of the cell. There is no upper disco- 
cellular, the lower discocellular is abruptly bent, where it throws off a small recurrent 
nervule. ‘The costa of the primaries is strongly arched near its proximal end. The 
antenne have thirty-three joints, the terminal nine forming a moderate-sized club.
