E. metazonata Hmps. (38 a). Hindwings of a bright orange-red, the black marginal band narrower metazonata. 
in the middle of the margin. Abdomen bright orange with a black dorsal stripe. Volcano Chiriqui, and Colombia. 
E. rogersi Drc. undoubtedly approximates the form brevicornis of aurantiaca, but it is much larger, rogersi. 
almost the size of metazonata. Forewings brown, tinted yellow; on the rosy-purple hindwing there is a black 
spot in the disc and one above the proximal angle. Costa Rica.’ 
E. esula Drc. (38 b) is almost like arbela, but smaller, the marginal band of the hindwing broader esula. 
and of a deeper black; the brown forewing with an orange-coloured costa. Mexico; apparently rare or very local. 
E. fragilis Streck. (= costata Stretch, opelloides Graef) (38 c). Forewing brown with a reddish-yellow fragilis. 
costal stripe; hindwing unicolorously orange, without the black marginal band. Texas. 
E. semirosea Drc. (38 a) is one of the largest species; forewing brown with a scarlet costa, hindwing .s temirosea. 
rosy-red with a broad black distal band being at the middle of the margin sometimes a little notched. Mexico. 
E. mathani Rothsch. (39 c) from Cundinamarca in Colombia resembles semirosea, the forewing deep mathani. 
wooden-brown; hindwings brick-red, the black marginal band narrower near the middle of the margin. 
E. laeta Guer. (= treatii Grt., rubropicta Pack.) likewise resembles semirosea, also with brown la eta. 
forewings and a red costal margin, the hindwings crimson with a black distal half; but the abdomen is likewise 
dark red with a dorsal row of black spots. South eastern parts of the United States (Florida); distributed also 
in Arizona. 
E„ ostenta H. Edw. (= calera Barnes) (38 a). Forewings like in semirosea, but the hindwings are ostenta. 
carmine only in the costal areas, otherwise quite black. From Colorado through New Mexico as far as Mexico 
and Arizona. 
E. pomponia Drc. (38 a) differs from ostenta, which it resembles extremely, by the palpi being black pomponia. 
(not carmine) at the base, and by the carmine costal spot of the hindwing being defined towards the black 
margin of the hindwing not in a uniform bow, but somewhat angularly. Mexico; very closely allied to ostenta 
as well as mirma.' 
E. mirma Drc. (38 b). Above almost exactly like pomponia, the red of the hindwings somewhat more mirma. 
extensive; different by the strong black marginal band beneath. Mexico. 
E. cetes Drc. (38 b) from Oaxaca (Mexico) has the marking and shape of mirma, though the bright eetes 
red parts of the latter are here orange-coloured. 
E. trigonifera Schs. (38 c). The hindwings almost entirely like cetes, the costal part more reddish- trigonifera. 
than orange-yellow. Besides, however, the forewing exhibits the ivhole basal half reddish-yellow, except the 
blackish-brown proximal margin. Mexico. 
C. pamphylia Drc. (38 b) is also from Mexico and similar to trigonifera, but the golden yellow extends pxmphyKa. 
farther distally at the costa of the forewing. 
E. tenuicincta Hmps. (38 c). Forewings wood-coloured, the golden yellow hindwings only very tenuicincta. 
narrowly bordered with black. Peru. The southernmost species known of the genus. 
E. disparilis Grt. (38 d). From Cuba; on the brown forewing some white spots, on the yolk-coloured disparilis. 
hindwing black spots. 
E. heros Grt. (38 d) likewise from Cuba, is the largest species, quite golden yellow, the forewing with heros. 
duller, the hindwing with somewhat more distinct, dark nebulous spots. 
E. pallicornis Grt. is another Cuban species, the size of which is between heros and disparilis. The pillicornis. 
brown forewings are speckled and spotted white, between and towards the margin shaded dark; the hindwings 
are reported to be dull pink or reddish-orange, with dark spots at the cell-end and above the proximal angle. 
The butterfly is certainly very rare, unless it be an aberration of disparilis; it is not represented in any 
museum; the type does not exist anymore. 
2. Genus: Virbia Wkr. 
This genus with about 20 species is distributed more to the south than the preceding, but it does not 
occur anymore in the United States. The species are throughout yellow and black, or yellow and dark brown, 
just like those of the preceding genus were preponderantly carmine. In the structure the Virbia are very much 
like the Eubaphe, but they differ by the upper median vein of the forewing branching off with the lower radial 
from the same place, the lower cell-angle, whereas in the Eubaphe the uppermost median vein (which is nowadays 
often denoted as the lower radial vein) rises far before the lower cell-angle. — Most of the Virbia are rather 
rare butterflies which are nearly exclusively taken by the lamp, only V. subapicalis and medarda being more
