black-brownish. Forewings very much like in aoris, hindwings brownish-black with a diaphanous disc. 
British Guiana (Demerara). 
E. ecuadoris nom. nov. (= buchwaldi Rothsch.) is much smaller than aoris. Head and thorax dark ecuadoris. 
grey, collar lighter grey; neck, abdomen and the whole underside monotonously yellow. Fore wings light grey 
with transverse rows of dark grey spots; 4 of them, next to the base above and below the inner-marginal 
vein, bordered with yellow. Hindwings diaphanous whitish-grey with a broad drab margin and apex. Length 
of forewings: 14 mm. West Ecuador. 
E. ladas Schaus. Head and thorax are brownish-black mixed with greyish-white. Abdomen black- ladas. 
brownish with orange-yellow transverse bands on the 3 last rings, which are more prominent in the $. Fore¬ 
wings grey-white with blackish-brown veins; in the middle of the cell and at the end minute darker spots. 
Before the middle there are traces of a dentate line, behind the middle an irregular line, the latter sur¬ 
rounds the cell in an arch-like way and then turns towards the middle of the proximal margin. Before the 
margin dark, small sagittal spots. Hindwings blackish-brown, in the $ towards the base lighter. Expanse 
of wings: 24mm. Rio cle Janeiro. 
E. xanthoperas Hmps. (= abdominale Druce) (25 i) has brownish-grey forewings with a small dark xanthope- 
spot in the middle of the cell, a larger one at the end of the cell and minute, antemarginal sagittal spots. ras - 
Hindwings brownish-white diaphanous; body brownish-grey, the 3 last abdominal rings orange-yellow. Mexico; 
Guatemala; Costa Rica. 
E. flavicincta Schaus (25 h) is easily recognizable by the penultimate yellow abdominal ring, whereas flavicinda. 
the others are unicolorously blackish-brown. Characteristic is, furthermore, the marking in the cell of the 
forewing exhibiting in the middle a black circle and on each side of it a black streak along the cell-fold; 
moreover, on the whitish-grey forewings, the veins and dentate lines are blackish; the transverse vein appears 
as a light grey angular streak out of the blackish surroundings. The hindwings are light grey, bordered with 
blackish. Peru and Bolivia (Rio Longo). 
E. sadana Druce. The head is black with a red vertex; the rest of the body dark brown, beneath sadana. 
rosy-red; legs brown. Forewings unicolorously dark brown, hindwings diaphanous brownish-black. Expanse 
of wings: 33 mm. Peru (Carabaya). 
E. mathani Schaus. Head and thorax brown, in the neck 2 yellow spots. Abdomen above blackish- mathani. 
brown, beneath yellow, with brown bands; anal hair yellow. Forewings brownish-grey with dark brown mar¬ 
kings: a basal spot, an antemedian, undulate, bent band, in the cell a square spot followed by a lighter 
brown transverse spot, at the cell-end and behind it a large spot, divided by the veins into 6; a postmedian 
row of longish spots and an antemarginal, similar, though smaller one. Hindwings brownish-grey, towards 
the base diaphanous. Expanse of wings: 33 mm. Ecuador. 
E. rabusculum Dogn. Body' dirty white, mixed with grey, abdomen curled grey, the last rings rabusculum. 
covered with long, grey hair. Forewings whitish-grey, traversed by 6 broad grey transverse bands: a basal 
one spotted black, one behind it, an antemedian band, close behind it a fourth growing much broader on the 
transverse vein and forming a large black costal spot, and 2 at the margin, which are scarcely separated, 
the distal one darkened on both the upper radial veins. Fringes grey. Hindwings white with a minute 
discal spot and a grey costal margin and border, at the apex broader. Expanse of wings: 45 to 48 mm. 
South East Peru. 
E. costulatum H .-Scha.ff. (25 h). The forewings are marked as in phaeoproctum, but the yellow is costulatum. 
darker and the apex of the abdomen is orange as in aroa. Panama, Venezuela. 
E. costinotatum Dogn. Anterior body blackish, marked whitish-yellow; abdomen black, the last eostinola- 
ring yellow, beneath black; the rest of the ventral side dirty white. Forewings yellow-white, the veins and ium - 
the middle costal third black; before the apex is a large white spot extending down as far as the middle 
radial. Forewings black, towards the costa whitish. Expanse of wings: 30 mm. Brazil (Paranapanema). 
Schaus places this species to the genus Hyaleucera and beside sororia. 
E. aroa Schaus (= costulatum Druce ) (25 h) has whitish forewings, costal margin, discocellular and aroa. 
proximal margin striped yellow. The veins, a stripe in the discocellular and the submedian fold greyish- 
brown, as far as behind the cell-end, in some places thickened to a spot, then follows a reniform, light spot; 
the apex is again smoky grey. Thorax and abdomen grey-brown, in the <$ the last ring, in the $ the two last 
rings orange. The venter is more or less whitish. On the hinclhead 2 orange-yellow spots, the shoulder- 
covers striped orange. Distributed from Mexico to Brazil. 
E. tenellulum Schaus (25 h). Palpi, head, collar and thorax brownish-grey; stripes on the shoulder- tenellulum. 
covers and 2 spots in the neck orange. Abdomen, except the orange-yellow last ring, brown-grey, on the 
ventral side more or less whitish, in the basal half and on the veins round the cell-end light ochreous-yellow. 
Blackish-brown, oblong spots arranged similarly as in aroa leave a reniform, almost purely white spot free 
before the apex of the wing, this spot projecting between the middle radial and the lowest subcostal vein
