E. rothschildi nom. nov. (= ockendeni Rothsch. nec Druce) (25 i) greatly resembles the preceding, 
being likewise smaller than lineatum, with yellowish-grey, semi-diaphanous wings, with faded pale grey-brown 
markings which have almost vanished in the basal half. Venezuela; Ecuador; Peru. 
E. discolor Wkr. (= rububa Druce) (25 i) has brownish-white forewings with faded, grey-brown spots; 
the largest occupies the middle of the costal margin and encloses a roundish, light spot at the cell-end; further 
spots are at the apex, in the middle of the distal margin and at the proximal angle. The pale hindwings 
exhibit a somewhat darkened margin. Head, thorax and abdomen brown-grey, on the forehead a metallic 
blue spot. Widely spread from Mexico through the whole of Central America and Brazil as far as Bolivia. 
E. zizana Dogn. Head and thorax brown, forehead blue. Forewings light grey, traversed by 4 lighter 
veins, the 2 proximal ones regular and parallel, the 2 distal ones more irregular and with several white 
spots. Hindwings whitish, at the apex and margin smoky brownish. Expanse of wings: 30 mm. Ecuador (Loja). 
E. nervulum Rothsch. Body sooty wooden brown, on the head with a blue lustre; venter beneath 
in the basal half whitish. Forewings dirty white with brown veins and large, cloudy, dark brown spots in 
the disc and at the apex. Hindwings diaphanous grey, in the distal quarter darker. Length of forewings: 
15 mm. Ecuador. 
E. nubilosum Rothsch. somewhat resembles nervulum, of a deeper purple brown on the body, the 
head black with a blue lustre. The forewings are brownish white in the smaller basal half, with a darker 
brown base and some indistinct, small stripes; the distal two thirds are purple-brown, in the most distal third 
clouded whitish. Hindwings diaphanous whitish, at the apex dark grey. Length of forewings: 13,5 mm, 
$ 17 mm. Peru; Venezuela; Sa. Martha. 
E. carabayanum Schaus. Head grey, palpi and antennae black, forehead metallic dark blue; thorax 
grey, marked brown. Abdomen in the basal half grey, at the end black. Forewings grey, sparsely strewn 
with brown, with blackish-brown markings; a shade at the base, a transverse antemedian band, a broad 
shade from the cell-end to the costa, behind it a line running in an arch round the cell, being the thickest 
at the proximal margin, a broad antemarginal shade, interrupted between the lower radials, at the margin 
spots at the apex, between the lower radial veins and at the proximal angle. Hindwings white, at the costa 
and apex blackish-brown. Expanse of wings: 35 mm. Peru. 
E. sordidescens Rothsch. has duller, darker forewings than cardbayana with obsolete markings. The 
head is blue, thorax and abdomen sooty wooden brown, the venter beneath in the basal half whitish. Fore¬ 
wings pale wooden brown, in the distal two thirds with darker brown spotted clouds. Hindwings diaphanous 
light wooden brown. Length of forewings: 19 mm. Venezuela; Peru. 
E. coeruleocaput Rothsch. is considerably larger than the preceding. The head is metallic blue, the 
thorax dirty grevish-white, bordered with a sooty black; the abdomen is above light sooty blackish, beneath 
in the basal half all white, the posterior rings black, with white bands. Forewings creamy white, strewn 
with brown scales, veins and basal area blackish-brown. An irregularly spotted, dark brown oblique band 
extends from % of the length of the costal margin to the proximal angle and gets much broader below 
the median; some more deep brown spots are at the transverse vein and above it, at the apex and between 
the upper median and middle radial vein. Hindwings whitish diaphanous, at the border and apex dark grey. 
Length of forewings: $ 24mm, $ 26 mm. Peru. 
E. nebulosum Dogn. (25 g) has a dark brown body, with a somewhat lighter abdomen, forehead blue. 
Forewings dark brown with a faded, grey antemedian band; behind the cell a similar one, interrupted between 
the median veins, turning inward on the lower median vein as far as the cell-end. Antemarginal spots above 
the middle and 2 at the proximal angle. Hindwings diaphanous light brownish, at the margin and apex 
browner. Expanse of wings: 44 mm. Ecuador (Loja). 
E. album Druce (= agylloides Dyar) (25 k) is of a pure white, strikingly resembling some American 
Agylla- species; only the teeth of the antennae are blackish. Hitherto known only from Mexico: Jalapa, 
Orizaba, (January), Mirador (March, April). 
E. vestale Schaus (24 k) is larger and with broader wings than the preceding, likewise unmarked white, 
but the wings more thinly scaled, semi-diaphanous, and with a slight greenish silvery gloss. From Peru, 
Sao Paulo, and Rio Grande. 
146. Genus: Metacrocea Dyar. 
Distinguished from Eucereon by the 2nd abdominal ring being strangulated. The veins are, on the 
whole, the same; on the forewing, the 1st subcostal vein comes from the upper cell-angle. On the hindwings 
the subcostal vein rises on a short pedicle with the uppermost radial.
