A pretty species, distinguished by its delicate grey colour and by the extensive patch 
of chalky white on the apical portion of the primaries. Mr. Bates described it from 
specimens obtained by us in the interior of Guatemala !, where, however, it is by no 
means common, and confined, so far as we know, to the department of Vera Paz. We 
have a single specimen from Acapulco, in Mexico, captured by Captain A. H. Markham, 
and it also occurs in Yucatan, according to Boisduval?; the same authority records it 
from Costa Rica, whence, however, we have no specimens, though we have several from 
the adjoining State of Nicaragua. 
A single specimen captured by Mr. F. Simons at Manaure in northern Colombia 
differs to some extent from Central-American examples. ‘The cretaceous white of the 
primaries is more extensive and more broken up with grey marks; it has also some white 
spots near the apex of the secondaries. ‘These discrepancies are to some extent in the 
direction of A. ferentina, and the specimen may hereafter prove to be an extreme form 
of that insect, or possibly a distinct species. 
6. Submarginal ocelli of secondaries black with a blue centre.

Hab. Mexico (Mus. Staudinger); Guatemana, Chuacus (f. D. G. & O. S.1, Hague). 
The first example of this species was taken by us in the little hamlet of Chuacus in 
Guatemala, situated in a valley which opens into that of the Rio Motagua at an 
elevation of about 3000 feet above the sea. This specimen was a female and was 
described by Mr. Bates!. Mr. Hague subsequently obtained a series of examples from 
the same spot, where alone it has yet beenfound. With all the characteristic markings 
of this genus, A. atlantis has peculiarities not shared by any other species except the 
following. The chief points of note are the strong greenish tinge of the upper surface 
of the wings, the rounded primaries, the blue pupil of the ocelli, and the black apical 
portion of the underside of the primaries of the male.
