Portuguese, German and British East Africa. — - chalcis Fldr. (36 d) seems to be the West African form and chalcis. 
differs chiefly in having the black submarginal line at least on the hindwing composed of bidentate, W-shaped 
transverse marks; in the $ the hindwing is dark brown above and only towards the anal angle more or less 
tinged with greenish; in the $ the ground-colour of both wings above is green and the forewing has the anterior 
part filled in with white in cellules 4—6 between the first and second transverse row of spots; the hindwing 
of the d is much longer produced at the anal angle than in achlys. On the west coast of Africa to the Ubangi River. 
E. oliva Suff. recalls achlys in the greenish ground-colour, but is most nearly allied to aurantiaca, which, oliva. 
however, is always dark without any greenish gloss; the $ is more slender, entirely greenish above, with 
the markings much as in aurantiaca, but very sharply expressed; row of white dots before the apex of the 
hindwing distinct; the $ above is likewise similar in markings to the last-named, but these are also very sharply 
expressed; the white median band of aurantiaca is only represented in the anterior part by light grey colouring; 
it is continued posteriorly in greenish to the inner margin of the hindwing; a greenish distal band is also present 
on both wings, if one may call it a band at all, as here only the dark markings are margined with greenish; 
the row of light dots not standing out distinctly, their colour being light grey instead of white; the spots beyond 
them are produced into longitudinal streaks. In the shape of the wings oliva recalls plautilla more than aurantiaca, 
especially in having the distal margin of the forewing more strongly excurved, but the hindwing is also similar 
to the former. Under surface of the bright ochre-yellow, of the $ very similar to that of aurantiaca, but 
more uniform (according to Bartel). Togo and Cameroons. $-ab. albula Suff. only differs in having the white albula. 
discal band of the forewing continued to the hindmargin. Togo. 
E. ochracea Bartel differs from all known species; it is nearest to plautilla (36 d), but the $ of that ochracea. 
species is always entirely dark on the upper surface, while ochracea $ is grey-brownish, mixed with ochreous, 
most strongly in the cell, which on the forewing is almost entirely filled up with ochreous, and in the middle, 
where an ochreous band is present, which on the fore wing is indistinct, on the hindwing broad and sharply 
defined; the $, like that of plautilla ab. claudianus, is predominantly reddish brown on the upper surface, but 
differs from this in having the greater part of the forewing also brown; otherwise the markings are similar 
to the species named; in the the large blackish inner-marginal shade of the forewing of plautilla is not present; 
on the hindwing the blackish dentate stripe in the central part is much narrower and the blackish transverse 
shade following it is represented by a dentate stripe. In the $, as in some plautilla a rather broad whitish 
band is present in the distal part, consisting of single teeth and rays; the row of white dots follows beyond it; 
the black spots which it borders are strongly rounded; on the hindwing the black patches in the cell are sharply 
marked, while the median dentate stripe is dark brown and little prominent; the distal-marginal part of both 
wings is brownish grey in the The under surface of both wings in the $ is light yellow-brownish, very 
uniform, weakly marked with brown (not black); the row of dark spots in the distal part of the forewing is very 
indistinct and only faintly bordered with whitish; in the $ the under surface is similar to that of plautilla, but 
more uniform, more violet-brown, with weaker markings, the white markings on the forewing only reaching 
to the middle; hindwing very uniform violet-brown, not marked with white, but only faintly with dark brown 
and violet. Antenna above not black, but red-brown, as on the underside. Congo, at Mukenge. 
E. fulminea Bartel. This species is unknown to me and only one $ is known, which is described by its fuiminea. 
author as follows: ..Like aurantiaca Auriv., but the distal margin of the hindwing much more strongly outcurved, 
so that the apex projects much more strongly. In place of the white median band of that species there is only 
a faint light appearance; the black median (nebulous) stripe follows an entirely different course; it does not 
turn posteriorly straight towards the inner margin, but is closely approximated to the subdorsal, thus strongly 
turned towards the base; the distal dark macular stripe and also the row of white dots have a more undulate 
course. The hindwing is particularly characterized by three distal stripes, which in the posterior half of the 
wing have the spaces between them green; the outer of these stripes is also composed of much stronger teeth 
and curves than in aurantiaca. The under surface, too, is quite differently coloured, being predominantly 
brick-brown, tinged with violet in places; besides the characters already emphasized in the description of the 
upper surface the less extended light colouring at the apex of the forewing is at once noticeable, as also the 
red-brown (not ochreous) distal margin of this wing; all the markings are brown, not blackish; distal half of the 
hindwing almost entirely brown with whitish markings, similar to those of aurantiaca^ . West Africa. 
E. aurantiaca Auriv. is very nearly allied to the following species, only differing in the male in the aurantiaca 
distal margin of the forewing projecting decidedly more at the extremity of vein 4, in the transverse rows of 
dark spots on the upper surface being lighter and not widened into large spots in cellules 1 a and 1 b on the 
forewing and the under surface much lighter and more uniform yellow. In the $ the wings have the ground¬ 
colour above dark grey-brown to the distal margin with the same transverse rows of dark spots as in the <$; 
on the forewing there is a broad white band between the first and second row of spots, extending from the costal 
margin to vein 3 or 2; the under surface is light yellow as in the A- Congo.
