E. thrailkilli Schs. (54 d) has the size and shape of a medium-sized dryas, but the forewingsrare more 
distinctly watered yellowish-brown, and the hindwing is in the distal half tinted rosy-red, without a dark mar¬ 
ginal band. The body is of a bright ochreous-yellow, marked blackish-brown, the tegulae showing one thick 
black dot each, the patagia being quite blackish-brown with an orange-yellow proximal margin. Abdomen 
banded black. Mexico. 
E. systron Schs. (54 d) from Parana is smaller and quite dark brown, with a collar finely edged with 
yellow, the abdomen posteriorly golden yellow, the segments margined dark; on the forewings there are some 
dispersed light dots; the hindwings are lighter smoky greyish-brown. 
E. colombiana Rothsch. (54 c) has unicolorously light yellowish-red forewings with a yellowish- 
white costal margin; in the cell and discal fold near the border a dull, dark streak. Hindwings diaphanous 
white. Fassl discovered it on Mount Tolima in Colombia. 
E. sarcochroa Dgn. (54 e) is very closely allied to colombiana, but the ground-colour of the forewings 
is more flesh-coloured, from which the name of the insect is derived. Also the hindwings are distally flesh- 
coloured. Like colombiana from Mount Tolima in Colombia. 
E. ochrota Hmps. (54 e) is the size of the preceding and has about the same colour of the forewings, 
but the hindwings are not diaphanous white, but dull greyish, with a rosy distal hue. The abdomen is yolk- 
coloured, with black bands. Colombia to Bolivia and Peru. 
E. umber Cr. Blackish-brown, hindhead and patagia with yellowish-red-orange spots; abdomen 
above orange, the margins of the segments and the hair towards the base of the abdomen brown. Hindwings 
of a rather much lighter brown. 70 ($) to 8G ($) mm. Surinam and Panama. 
E. castanea Rothsch. (54 e) is much smaller than umber, almost quite unicolorously dark brown, 
but a slightly prominent,' darker nebulous stripe defines proximally the marginal area of the forewing, a feeble 
darkening resting above the cell-end and hindwing as well as abdomen are lighter towards the base. Peru. 
E. hades Drc. (54 e) has the size and approximate shape of the preceding, but it is quite unicolorously 
deep blackish-brown with an orange-yellow apex of the abdomen. Likewise from Peru. 
E. atrata Fldr. (54 f). This species initiates a series of almost black butterflies, and it is doubtful 
whether all that have been described as distinct species should remain or rather be regarded as vicarious forms 
of few species. In atrata the head and collar, the two first abdominal rings and two bands before the black 
terminal part of the abdomen are of a bright orange-yellow. These two dorsal bands may be so broad that 
the whole abdomen turns orange except a saddle-spot and the two last segments above. Tegulae and patagia 
show one thick black dot each; the middle of the hindwing is hyaline, traversed by thick black veins. From 
Colombia and Ecuador to Peru and Bolivia. The figured specimen from Pozuzzo. -— felderi Rothsch. (54 g), 
likewise from Peru, shows the orange ring of the base of the abdomen narrower, that before the apex, however, 
much broader, the hyaline area in the middle of the hindwing reduced. 
E. subterra Rothsch. (54 f), likewise from Peru, but from a different district, as the preceding, has 
the abdomen above quite black except the narrow ring at the base, the sides and apex laterally and beneath: 
above the apex is also black. 
E. atrobrunnea Rothsch. (54 f). Larger, with broader wings, head and collar orange, as well as the 
abdomen at the base and on the posterior segmental indentations. Hindwings dark brown, without the hyaline 
discal area. Venezuela. 
E. terraoides Rothsch. (54 f) from Peru and Bolivia is almost like atrata , but the dorsum of the abdomen 
is not yellow at the base; the hyaline spot in the hindwing only reaches about the middle. Perhaps a form 
of the following. 
E. terra Drc. (54 f) entirely resembles terraoides, but the abdominal dorsum laterally with small 
yellow dots, the hyaline part of the hindwing extends on the median beyond the middle of the wing. Peru 
and Bolivia. We figure it from the Rio Songo. 
E. chimaera Drc. (54 g) from South Brazil and Paraguay greatly resembles the preceding, bid the 
head and collar are not yellow, but the vertex and patagia only show yellow dots, the abdomen is only laterally 
spotted yellow, the whole basal half of the hindwing white. 
E. tuliginosa Rothsch. (54 g). The whole bocty and forewings monotonously blackish-brown; the 
hindwings, however, quite white except the faintly brownish apical part. Peru. 
E. carbonaria Dgn. (54 h). Bod}" and forewings coloured like in fuliginosa, but the hindwings of a 
dirty earth-colour. Bolivia and Peru. 
carbonaria.
