oblique whitish stripes near the base (the posterior one crossed by a black 
streak), and four exterior spots. Outer margin greyish brown, with a 
plumbageous submarginal line. Hind wing whitish, with three rufous 
belts across the basal half (the two outer ones slightly divergent from 
costa to abdominal edge, and enclosing a greyish belt with plumbageous 
streaks). Outer limb grey, with two rufous-brown streaks, enclosing two 
large, round, black ocelli, with round plumbageous pupils and yellow 
irides; two black lunules, edged with plumbageous, near anal angle. 
@. Expanse 1” 10’. Above, precisely the same as in LE. postverta, except 
that the anal ocellus has a round instead of a crescent-shaped plnmba- 
geous pupil. Beneath, the same as in the ¢ above described. 
I found this species only in the neighbourhood of St. Paulo, Upper 
Amazons. It appears to be a local form of EZ. postverta, the type not 
being found in its company. As a local variety, however, it is well 
marked and constant. It is remarkable that such a modification of 
a species should occur in a district situated near the centre of the 
area of distribution of the type.

3. Expanse 1” 10-2" 2”. Similar in form and general colour and 
markings to EL. postverta. Wings, above, of the same hue of green, with 
spots of underside shining through; the outer border of the fore wing, 
however, is much broader, and has two deep, rounded emarginations on 
its inner edge. There is a curved black streak beyond the end of the 
cell, but no black spot on the disk. The hind wing, above, has a broadish 
black border, with a distinct inner limit, but without sinuation. There is 
also in’some examples a round black spot near the anal angle. eneath, 
the fore wing is tawny rufous, with five irregular white spots, namely, 
one, oblique, over the median nervure, a second, flexuous, across the 
hinder part of the disk to the hind margin, a third, elongate, near the 
middle of the costa, a fourth, subapical, broad, and elongated, and, lastly, 
a fifth, behind the middle of the ,outer border. There is a submarginal 
plumbageous line, and two lines of the same hue in the cell, the basal one 
almost circular and the other transverse, both partially edged with black. 
Hind wing very similar to that of EZ. postverta; but the ocelli are different : 
instead of having plumbageous pupils and yellow irides, they have black 
pupils with the outer sides plumbageous, and yellow edging on the inner 
sides only. The outer submarginal rufous line is also wanting, and the 
outer edge of the central belt is flexuous instead of straight. 
This species was one of the rarest of the genus. I met with it 
only on the Upper Amazons, at Tunantins and St. Paulo.

gd. Expanse 1" 10'". Above, deep black ; a large spot at the base of the 
fore wing, and a small one at the base of the hind wing, silky green.
