strongly convex towards the base. A subterminal macular band with the longest spot between the median 
veins and the largest between the middle radial and lowest subcostal vein; a terminal row of spots from the 
apex to the upper median vein, below it the margin is white. From Mexico (Orizaba: March and August) and 
Costa Rica (Juan-Vinas). 
E. scyton Cr. (25 i) differs from aroa by grey forewings with a brown tint and without any yellow, with 
black veins and other markings: an antemedian, doubly angled transverse line; a postmedian, oblique line 
from the costa to the upper median vein, where it makes an angle and runs to the middle of the proximal margin; 
behind it there is a light spot with a dentate, distal border. The marginal area is dark with irregular, often 
contiguous, grey spots. Hindwings diaphanous blackish-brownish, towards the margin darker; body as in aroa. 
Expanse of wings: 32 mm. Distributed from Mexico through British Honduras, Surinam as far as Sao Paulo. 
E. schausi Rothsch. is much larger and of a purer white than scyton. Head and thorax greyish-white, 
margined by a darker sooty grey, in the neck spotted orange. The abdomen is sooty grey, the last ring yellow, 
proximally margined by black. The underside is broadly banded white. Forewings white with blackish-brown 
veins, irregular spots and stripes. Hindwings diaphanous grey with darker margins. Length of fore wings: 
19 to 23 mm. Mexico; Costa Rica; Colombia; Ecuador. 
E. lithosioides Rothsch. Head and thorax light yellowish brown, abdomen darker sooty brown, with 
a yellowish anal apex. The forewings are in the basal 4 / 5 yellowish wooden brown, in the distal fifth more 
yellow reddish; antemedian and postmedian, curved, darker brown transverse bands. At the transverse vein, 
on the median, at the base of the lower median vein, and in the disc and at the proximal angle on the inner- 
marginal vein there are black dots. Hindwings brownish grey, in the disc diaphanous. In the $ the fore wings 
are darker ribbed; the transverse bands are more distinct and at the transverse vein there are 2 dots. Length 
of forewings: 17 to 19 mm. Rio de Janeiro; Venezuela. 
E. fuscatum Rothsch. Head and thorax dark brown, in the neck spotted orange. The abdomen is above 
black with an orange-yellow anal apex, beneath yellow, banded black. Forewings light clayish-brown or more 
greyish brown with irregular, dark brown transverse bands at the base, in, behind the middle, and before the 
margin. Hindwing in the basal half diaphanous drab, distally darker grey. Length of forewings: 17 mm. Ecuador. 
E. fuscobrunneum Rothsch. is uniformly dark olive-brown with a black abdomen and a yellow anal 
end. The forewings exhibit 2 darker transverse lines and a whitish postmedian shade from the costa to the proxi¬ 
mal angle. Hindwings diaphanous sooty-blackish. The $ is larger, the hindwings darker. Length of forewings: 
15 mm, $ 17,5 mm. Ecuador (Paramba). 
E. fuscoirroratum Rothsch. is a small, monotonously dark chocolate-brown insect. The forewings are 
watered with numerous, irregular, yellowish-grey transverse lines and bands. Length of forewings: 14 mm. 
Venezuela. •—- subsp. minor Rothsch. from the Rio Madeira (San Antonio) is still smaller and exhibits orange 
spots on each side of the abdominal rings 3 to 6. 
E. strix Rothsch. The body is dark brown, beneath mixed with whitish. Forewings wooden brown, 
striated darker brown; at 2 / 5 of the length of the costal margin there begins a broad black line forming an arch 
and running on the inner-marginal vein into the base; at the transverse vein there is a dark line, behind it a 
bent transverse line followed by an oblique whitish line terminating on the lower median vein into the margin. 
The apex and a bent antemarginal line whitish. Hindwings diaphanous sooty grey, veins and margin darker. 
Length of forewings: 21 mm. Colombia. 
E. ino Druce has an entirely unicolorously fawn-coloured body with a light yellow anal tuft. Forewings 
light fawn-coloured with darker brown veins and 2 narrow, brown, transverse lines, the first one near the base, 
the 2nd at the cell-end. Hindwings whitish diaphanous, apex and margin brownish. Expanse of wings: 42 mm. 
Colombia. 
E. mizar Druce. Head and collar brownish-white, thorax and abdomen dark brown, the 2 last rings 
orange; venter banded white. Forewings grey-white, clouded in a darker brown, with dark brown veins. Hind¬ 
wings dark brown, towards the base lighter. Expanse of wings: 40 mm. Ecuador. 
E. resina Druce. Anterior body grey, abdomen black, legs brownish black. Forewings grey-white, 
strewn with a darker grey, in the cell with a round, dark-grey spot; a dark-grey zigzag-line runs from the 
apex to the proximal angle. Hindwings dark grey. Expanse of wings: 44 mm. Colombia. 
E. ignotum Druce. The body is unicolorously brownish-grey, the legs whitish. Forewings whitish, den¬ 
sely dusted with a dark grey. Hindwings diaphanous white, at the margin broad black. Expanse of wings: 
42 mm. South East Peru. 
E. irrorata Schaus. Palpi and forehead whitish; neck, collar, and thorax light brown: a white stripe 
extends from the base of the antennae to the base of the wings. Abdomen light brown towards the base, 
more grey posteriorly. Forewings brown, finely watered with black, behind the middle condensed to an
