Upper Amazons; rare at Ega, but more abundant a few hundred 
miles further west, at St. Paulo. I met with only one female, namely, 
in the heart of the forest at Ega. Its close resemblance to the figure 
of Cramer leaves no doubt about the right name of the species.

3d. Very similar in shape and colour, above, to E. Castaha (Hewits. /. ¢. 
f.4); fore wing rather more pointed. In size it is much larger, measuring 
2" 5'", Beneath: fore wing slaty brown, with the apex reddish; the 
central part is dusky, with three ashy spots, and the cell has a distinct 
black spot. Hind wing reddish, with a bluish or slate-coloured gloss ; 
the basal part has two short castaneous lines; the central line of the same 
hue is much inflected in the middle, owing to the anterior ocellus lying 
much nearer the cell than usual, and out of the line of the other two. The 
anterior ocellus is castaneous, with a paler iris, and two large pale-blue 
pupils bordered with black: the inner one of the two anal ocelli has a 
small pupil also of a pale-blue colour, but the outermost has only an ob- 
scure central spot. 
Q. Same shape as the f. Above dark brown, with a light violet-blue 
tinge, especially near the base ; apical part of fore wing rather darker, and 
crossed by two macular belts of a dull-whitish hue, each belt consisting 
of three ill-defined spots. Beneath same as the ¢, but much paler, the 
hind wing having a light-reddish hue. 
This species has pretty nearly the same range as #. Veronica; the 
two being found in great numbers at Tunantins and St. Paulo. It 
also occurred further east, at Ega, but was there a very rare insect.

A. very abundant species in some parts of the Upper Amazons. I 
once saw it in flocks of many hundred individuals (males only), flying 
over a half-dry watercourse near the village of Caicara.
