E. casca Dogn. (25 c). The large, white, subapical oblique spot of the brownish-black forewing makes cawa. 
the species easily recognizable; the veins are striped orange-yellow, of which colour are also 3 small costal spots, 
the third at the beginning of the subapical spot; a small spot in the middle of the cell is whitish. Hindwings 
diaphanous with blackish margins. Body blackish-brown, anterior body with orange stripes and spots, the 
three first ventral segments with white bands, the two last rings above spotted orange. Ecuador, Bolivia. 
E. pseudocasca Rothsch. is discernible from casca (25 c) by the pale sea-green, not orange-yellowish pseudo- 
veins and spots; the dark ground-colour recedes greatly; the basal area of the hindwing is of a much purer 
and more extensive white, and the ventral side exhibits a white, not yellow spot. Length of forewings: 
19 mm. Peru (Carabaya), taken in January. 
E. albinotum Dogn. is smaller than casca (25 c) and differs by the absence of the white spot on the albinotum. 
metathorax, the abdomen being entirely brownish-black, only the anus and a small dorsal spot on the 1st 
ring being yellow, beneath the rings are margined with yellow. The postmedian white spot on the forewing is 
shorter, extending only to the middle radial, and is dentate on the 1st radial vein; beside the small orange spot- 
above it there are at the costa 2 more, one in the middle. Expanse of wings: 34 mm. Colombia (San Antonio). 
E. darantasia Druce (26 1) is larger than casca (25 c), otherwise on the whole rather like it, but the white darantasia. 
spot behind the cell is absent ; instead of it we notice a very pointedly dentate, yellowish transverse line. 
In the middle of the cell and at the end of it there are black spots, between them a small whitish spot. 
The orange spots in the neck and the whitish spots on the metathorax are absent. Expanse of wings: 46 mm. 
Costa Rica. 
E. flavicaput Hmps. (= leucophaea Druce) (25 b). This species and the following ones are very much flavicaput. 
alike; the forewings exhibit, on the yellowish ground-colour, dark veins and 3 dentate lines crossing each 
other. E. flavicaput is one of the darker species, of a yellow-brownish ground-colour, suffused with olive- 
brown particularly at the proximal margin, base and cell-end. The brownish-grey head exhibits on the ver¬ 
tex two orange spots, the two last abdominal segments are orange. Mexico, Guatemala, Costa Rica, Ecuador. 
E. bricenoi Rothsch. Like flavicaput (25 b), but with a much lighter yellow ground-colour. The brieenoi. 
median area of the forewing and a postdiscal band from the subcosta to the upper median vein are entirely 
white. Venezuela (Merida); Colombia (Choachi). 
E. griseatum Rothsch. differs from the preceding by the olive-brownish grey-ground-colour. The hind- griseatum. 
wings of the $ are white in the basal 3 / 4 , in the $ entirely dark grey. Peru. 
E. leucophaeum Wkr. (25 c) from Brazil (Rio de Janeiro) and Paraguay is the most similar to the leuco- 
following species, distinguished by the metallic blue spot on the forehead, and the metathorax exhibits a pnaeum. 
blue spot, too, both, however, being absent in the $. On the abdomen the two last rings are above orange, 
in the $ on ly one ring. The hindhead shows two whitish spots. 
E. xanthurum Schaus (25 c) differs from leucophaeum particularly by the two dark orange spots on xanthurum. 
the hindhead. Forehead and metathorax in the do not exhibit any blue spots. In both sexes only the 
last abdominal segment is orange. Mexico, Costa Rica, Brazil. 
E. apicaflava Kaye differs from xanthurum chiefly by the absence of the antemedian dentate lines of apicaflava. 
the forewings which are clouded grey with darker scaled veins. At the costa above the middle of the cell 
there is a dark spot and in the surroundings of the transverse vein a large spot extending to the costa; 
the subapical dentate band is followed by a narrow, greyish-white macular band. At the proximal angle 
there is an irregular spot. Venezuela (Caracas). 
E. decorum Schaus. Body blackish-brown, thorax and shoulder-covers striped white; the 1st palpal decorum. 
joint, the hindhead, a small spot at the articulation of the forewing, and the 2 last abdominal rings are 
orange. Venter spotted white. Forewing as far as the posterior transverse line light brown, then whitish; 
the veins, a stripe from the base of the median to the upper cell-angle and one below the submedian are 
black; before the middle a dark transverse line being angular in the cell; the posterior transverse line makes 
two bends from the costa to the upper median vein, then turning to the middle of the proximal margin; 
an antemarginal, irregular, blackish-brown shade; the uppermost radial vein and the 2 subcostal veins above 
it are of a more intense black. Hindwings blackish-brown, in the disc whitish. Expanse of wings: 42 mm, 
$ 49 mm. Costa Rica. 
E. surcatum Dogn. Head and thorax brownish-grey; neck yellow; abdomen above black, the 2 last surcatum. 
rings yellow; the underside yellowish. Forewing yellowish-brown, traversed by irregular, rusty-red zigzag¬ 
lines: 3 near the base, and 5 in the distal half, between there is a large discal spot. Hindwings blackish. 
Expanse of wings: 42 mm. Ecuador (Loja). 
E. lutetia Druce (25 d) exhibits on the brown forewings behind the cell an indistinct white spot, lutetia. 
The brown body has an orange-yellow abdominal end. Panama.
