basal line diffusely rufous, followed by oblique rufous marks in and below cell; inner line faint towards 
costa, double and oblique from submedian fold to inner margin; orbicular stigma and inner edge of 
reniform represented by oblique double redbrown lines filled in with white, forming a V-shaped mark, 
with redbrown patch between them extending to costa, the outer edge of reniform with an oblique white 
striga beyond lower angle of cell; a somewhat diffuse redbrown median shade oblique from lower angle 
of cell to submedian fold, then vertical; outer line double, red brown filled in with white, minutely waved 
above and inwardly oblique below vein 4; a quadrate redbrown patch from costa to vein 6 before the 
whitish subterminal line, which is diffuse at apex, inwardly angled on discal fold, with a small triangular 
redbrown patch beyond it, then angled outwards to termen at vein 4, below which it becomes obsolete; 
a redbrown terminal line defined by white on inner side from apex to vein 5, followed by redbrown striae 
similarly defined; hindwing whitish suffused with redbrown; fringe white. The type, from Sarawak, Bor¬ 
neo, is a in bad condition. 
E. pulchrilinea Walk. Forewing yellowish suffused with rufous and irrorated with black; pulchrilinea. 
the veins a little paler; subbasal line marked by pale striae below costa and cell; with an oblique 
striga beyond them across cell; inner line white edged with black, slightly angled outwards below costa, 
then strongly excurved, a double white streak before it defining the submedian fold for a short distance; 
orbicular represented by an oblique white striga across cell, connected by a white streak on median vein 
with the reniform, which is whitish with a black line near inner edge, oblique, sejmrated from orbicular 
by a black costal patch, and followed by some black marks in the interspaces and a whitish striga 
beyond its lower extremity; outer line white slightly black-edged, incurved below vein 5; subterminal 
line white, defined on inner side by two black dentate marks below costa, then with blackish marks be¬ 
fore and beyond it to vein 5, angled outwards at veins 7, 6, and to termen at vein 4, then incurved 
and nearly obsolete; a terminal row of black spots internally edged by a white line; hindwing reddish 
brown; fringe yellowish with brown line through it. Sarawak, Borneo. 
E. juventina Cram. (= purpureofasciata Filler, lagopus Esp., pteridis F., formosissimalis Hbn.). juventina. 
(Vol. 3, pi. 44d.) Forewing olive brown, shaded in parts with black; the veins pale, towards termen rosy and 
cream coloured; inner and outer lines double, finely black, filled in with rosy and followed by rosy 
bands, that beyond outer line broad; both lines commence on costa as oblique white strigae before the 
subcostal angulation; stigmata olive brown tinged with rosy, their annuli white, more prominent in the 
reniform and forming a sort of hook at lower extremity externally; sometimes a rosy streak on sub¬ 
median fold beyond the very obscure claviform; subterminal line yellowish white, forming oblique streaks 
above veins 6 and 7, followed by a pale apical patch, angled inwards above 5, and acutely outwards 
at 4, thence obscure; a lunulate yellowish white line before termen; the terminal area rosy; fringe che¬ 
quered, ochreous and dark olive brown; hindwing ochreous, suffused with pale fuscous, with broad dark ter¬ 
minal border, an outer line, and cellspot; the Japanese form obscura Btlr. (Vol. 3, pi. 44d) is duller, all the rosy obscura. 
tints being greatly reduced in extent and brilliancy. Occurs in the Kliasia Hills, Assam; a widely spread 
palaearctic species. Larva green, with whitish or yellowish oblique lunular subdorsal markings; lateral line 
yellowish white; all the yellowish markings some times edged with pink; head reddish; on Pteris Aquilina. 
E. xanthopera Hmps. (19b). Forewing deep velvety black brown; the veins rufous; subbasal line xanthopera. 
white at costa; inner line black, edged finely on both sides with bluish white, white only and single 
above subcostal vein, preceded by a curved reddish streak from submedian fold to vein 1; orbicular stigma 
with rufous edges, oblique and narrower below; reniform with the lateral edges curved, slenderly white, 
the centre curved and rufous, its outer lower end followed by a brightly white triangular spot; outer 
line white at costa, then slender, edged inwardly by a row of black lunules preceded by a lilae grey 
shade, and outwardly by a belt of lilac grey and rufous; subterminal line marked by two snowwhite spots 
above veins 7 and 6, the apex beyond them rustcoloured, the line inwards to above vein 5 and outwards 
to vein 4 rustcoloured, but white before reaching 4; a white dash obliquely between veins 2 and 3; a 
line of white lunules before termen, preceded below vein 3 by lilac grey shading; fringe deep purple 
brown with a bright rufous line at base, swollen into spots at apex and vein 4; hindwing dark glossy 
fuscous; the fringe white, with fuscous inner line beyond a ferruginous basal line, which intersects the 
fringe beyond the veins; the <$ is not so dark, being more mixed with grey, and the markings clearer 
and thicker. Madras, Travancore, Ceylon, Tenasserim, and the Kei Islands. 
E. rivularis Walk. (19c). Forewing blackish on a greyish ochreous ground; the veins whitish; lines rivularis. 
double, blackish, filled in with white; orbicular stigma oblique, V-shaped, black with white edges; reni¬ 
form with a black, followed by a yellow, linear mark in centre, the edges white; a white spot beyond 
lower angle of cell; between the stigmata a black patch extending to costa; submarginal line white, preceded 
by black in the interspaces, with the usual angulations, but more or less obscure, a white line before
