E. metalobum limps, differs from minutum (24 g) by the lobularly extended, but not turned over 
and roughly haired proximal angle and anal angle of the £. The body is blackish-brown, mixed with grey; 
neck yellow. Palpal base, forehips and spots on the legs are whitish. Abdomen blackish-brown with yellow 
lateral spots on the last rings, beneath white. Forewings similarly marked as in minutum., greyish-white 
with brown veins, spots and dentale lines. Hindwings diaphanous grey, towards the margin tinted brownish- 
black. Expanse of wings: 30mm. Peru. 
E. phaeophlebium Hmps. The <$ hindwing exhibits a cover of yellow hair in a fold on the under 
surface at the proximal margin. Head and thorax yellowish-brown, the abdomen more blackish-brown. 
Palpal base, hips and ventral side light rosy red. Forewings yellowish-brown with darker veins, the hind- 
wings blackish-brown. Expanse of wings: 30mm. Argentina. 
E. integrum Rothsch. resembles the following species, but the border of the hindwing is convex, 
not concave. Head and thorax grey, with darker spots and stripes; palpi and legs are of a deep black. The 
abdomen is carmine, above at the base spotted yellow, with a black anal apex. Forewdngs yellowish drab, 
with black spots being similarly arranged as in excavatum. Hindwings dark grey, above the cell lighter 
diaphanous. Length of forewings: 19 mm. Amazon (Fonte Boa). 
E. excavatum Dogn. and the following species are very characteristic by the peculiar shape of the 
wings: both pair of wings are very broad, the hindwdngs between the greatly produced anterior and poste¬ 
rior angles concavely indented. The species before us has white forewings with black spots, the hindwings 
are whitish diaphanous in the basal halves, at the margins broadly black. The abdomen is carmine, at the base 
black, at the apex black and white. 
E. flavum Dogn. (24 h) is apparently not a form of excavatum, but rather a good species distinguish¬ 
ed by its larger size, the abdomen being above and beneath yellow, and by the peculiarly blurred, dull 
not distincly black spots of the forewdngs, French Guiana (St. Laurent clu Maroni, Nouveau Chantier). 
E. perexcavatum Rothsch. is somewhat larger than excavatum, with a unicolorously slate-grey abdomen, 
a sooty-black, not rosy-red underside, a unicolorously grey thorax, olive-yellow, not whitish-grey ground¬ 
colour of the basal 4 / g of the forewing, dark grey hindwings with a still more deeply concave border 
and a longer pointed proximal angle, Length of forewings: 19 mm. Amazon (Fonte Boa). 
E. kennedyi Rothsch. Head and thorax sooty-grey, marked lighter, neck orange. The abdomen is 
black, the 3 last rings above carmine-rosy; the whole underside is light carmine rosy. Forewings orange- 
yellowish, with a rosy tint, in the basal two fifths with a number of grey spots; in the disc there is a 
broad, irregular band composed of similar spots, behind the cell a dark-grey spot from the costa to the 
middle radial, and an antemarginal series of spots. Hindwings dark grey, towards the base extensively 
diaphanous lighter. Length of forewdngs: 16 mm. South Brazil (Minas Geraes). 
E. cinctum Schaus. Very much like the two following species, as large as metoidesis. Forewdngs 
and thorax greyish-brown with black markings. Abdomen black, above from the 5th to7th segments red, 
beneath yellow-reddish. Described from Trinidad. 
E. rubroanale Rothsch. is very near to cinctum (24 g) and differs by the sooty black, not yellow- 
reddish or whitish colour of the ventral side, much darker thorax and blackish-brown forewings on which 
the light markings are confined to a small spot in the cell and a very fine, undulate, postmedian trans¬ 
verse line. The hindwings are darker and more uniform by the much less diaphanous basal half. The 
present species is besides much smaller. Length of fore wings: 12 mm. Venezuela, Bolivia. 
E. metoidesis Hmps. (= cinctum Hmps., latifascia Btlr.) (24 h) is easily recognized by the costal 
margin of the hindwing being very concave at the base. Head and thorax brown, spotted black with two 
carmine spots in the neck. The black abdomen is carmine from the fifth to half of the 7th segment. The 
grey forewings, being more brownish at the margins, are spotted black, the semi-diaphanous whitish hind¬ 
wings at the border black. Distributed from French Guiana as far as the Amazon. 
E. obscurum Mdschl. (= stellifera Btlr.) (24 g) is a small species with narrow wings, easily recog¬ 
nizable by the bronze-lustrous black colour into which bluish-white scales, being partly in the shape of 
dentate transverse lines, are interspersed. The black abdomen has posteriorly a metallic blue lustre. Distri¬ 
buted from Mexico through Central America as far as the Amazon. 
E. lemoulti Schaus. The body is black, on the collar and thorax with a leaden lustre, in the neck 
orange. Forewings bluish-grey, with black veins and base of the proximal margin. Hindwings black, in 
the disc diaphanous. Expanse of wings: 29 mm. French Guiana (Maroni River). 
E. meruloides Schaus. Head, thorax and forewings dark leaden grey, the veins velvety black; a 
black postmedian shade. The abdomen is black. Hindwings bluish-black, in the disc diaphanous. Expanse 
of wings: 39mm. Peru.
