E. marcatum Schaus is allied to the preceding. Head and thorax white with black spots. Abdomen marcaium. 
rosy with a brown first segment and a black apex; with short brown snbdorsal stripes and a lateral row 
of black dots; underneath yellow-reddish. Forewings white with similar black spots as the preceding, and 
black margins; the most distal one of the costal-marginal spots is confluent with a large spot between the 
median veins, extending as far as the proximal angle. Fringes white, at the ends of the veins spotted 
black. Hindwings white with grey veins and border which grows broader at the apex and proximal angle. 
Expanse of wings: 33mm. Paraguay. 
E. elements! Schaus differs from all the species by the forewings being marked carmine, clementsi. 
Anterior body and forewings are of a deep dark brown; rings on the palpi, the basal joint of the antennae, 
the neck, 2 spots on the metathorax, hips and rings on the legs are carmine. Abdomen carmine with a 
triangular, brown dorsal spot at the base as far as the 3rd ring; the last ring and lateral stripes are like¬ 
wise brown. The forewings exhibit 3 red spots at the costal base, dentate and undulate red transverse lines 
before and behind the middle, ring-spots and reniform spots and oblong-oval rings before the margin. Hind- 
wings blackish-brownish, in the disc diaphanous. Expanse of wings: 36 mm, $ 42 mm. Sa. Lucia (West 
Indies). 
E. imriei Druce (24 1) is very easily recognizable by the black forewings being thinly strewn with imriei. 
yellowish-white scales, with 2 large, irregular, whitish costal spots before and behind the middle; the anterior 
one extends as far as the median, the posterior one to the upper median vein. Before and on the margin 
there are rows of more or less distinct dots. Hindwings blackish-brownish, towards the base diaphanous. 
The anterior body is black, on the thorax mixed with ochreous-yellowish. The neck, 2 spots on the meta- 
thorax, hips and abdomen are carmine, the latter above with a triangular basal spot, black apex and lateral 
macular stripes. Expanse of wings: $ 34mm, $ 42 mm. Guadeloupe; Dominica. 
E. chalcodon Bruce (24 1, 26 1) differs from the allied, very similar species by the antennae being chalcodon. 
white above. Forewings with a round cellular macula being prominently bordered with whitish. The basal 
joint of the antennae, and the neck are carmine. On the carmine abdomen only the 2 first rings are above 
black, the 3rd ring shows a black spot. Rio de Janeiro; Sao Paulo. 
E. pyrozonum Limps. (25 f) differs from chalcodon by the abdomen being black above and beneath, pyrozonum. 
with orange subdorsal spots on the 5th ring and orange dorsal bands on the following rings. Hindhead and 
shoulders spotted orange or carmine; hips carmine or orange. On the blackish-brown forewings the veins 
and linear markings are olive-yellow, arranged about as in chalcodon. Particularly conspicuous is a whitish, 
four-cornered spot behind the round, black cellular spot and a yellow-white marginal spot with 2 black 
dashes in it. Expanse of wings: 40 to 45 mm. Venezuela; British Guiana as far as Bolivia. 
E. sylvius Stoll (= lutulentum Moschl.) (25 a) is only half as large as latifascium which the species sylvius. 
resembles otherwise in the marking of the forewings and in the colouring of the abdomen, though the black 
dorsal spots are absent. The hindwings are much darker, almost one-coloured blackish-brown. Distributed 
from Mexico to Brazil (Amazon). The larva is densely covered with black and grey hair which grow much 
longer and thicker towards the posterior segments; the first segment exhibits some thick, yellow hair-tufts. 
It lives on orange-trees and makes itself a greyish-brown cocoon for the pupation. 
E. atitonia Druce is larger than the preceding species, head and palpi black, the neck yellow; on anionia. 
the brown abdomen only the 4 last rings above are red, the anus itself is black. The wings are more yel¬ 
lowish-brown with yellowish veins, the markings of a deeper black. Hindwings blackish-brown, the disc not 
being lighter. Expanse of wings: 40 mm. South East Peru. 
E. pseudarchias Hmps. (= arehias Druce) is a rather large species, distinguishable by the doubly pseudar- 
contoured pointed arch formed by the anterior transverse line between the submedian fold and proximal chias. 
margin, and by the carmine abdomen with a black terminal segment and a large, triangular, jet-black dorsal 
spot at the base. — The species is very common and distributed from Mexico to the Amazon. -— The red 
colour of the abdomen may be replaced by a burning orange: aurantiaca form. nov. (25a) which is before aurcmtiaca. 
us from Guiana and the Amazon. - — completa form. nov. is another form from the same habitats, in which compleia. 
the apical spot at the base of the proximal margin is entirely filled up with black, forming a large black 
spot. 
E. aeolum Limps. (= rhodophila Druce ) (25 a), from Mexico and Guatemala, has brownish-white aeoluvi. 
forewings with numerous, small, black-streak like spots: at the base on vein 1, two curved streaks form an 
oval being distally bordered by 2 spots of the anterior row converging into two rectangular spots; in the 
cell 2 spots being situate above each other; a middle row gets very irregular towards the cell-end. Some 
submarginal and marginal punctiforrn spots. Hindwings blackish-grey, somewhat transparent. Head and 
thorax grey, spotted black, in the neck two small orange spots. Abdomen at the base and at the end blackish- 
brown, otherwise carmine with black dorsal spots and lateral stripes, beneath yellowish. 
E. hampsoni Rothsch. extremely approximates aeolum and differs by the underside being rosy-red, hampsoni. 
not yellow. The forewings are spotted more indistinctly, and the spots are partly inclined to converge. The 
hindwings are diaphanous sooty-black, not light grey. Length of forewings: 16 mm. Bolivia.
