half of the wing, a submarginal border of brown spots along the hind margin, and two distinct brown spots in 
the discoidal cell, the white apical band nearly obsolete; the costa at the extreme base bluish white. Hind 
wing similar in colour to the fore wing, two brown spots in the cell, a whitish spot near the costa, situated 
near the centre of the wing, followed by a faint white line, but only as far as the first subcostal nervule. Ex¬ 
panse, 2. 7 in. $. Similar in colour to the male, the metallic blue on both wings somewhat brighter in co¬ 
lour. On the fore wing the white apical band broader and more strongly marked, a white spot at the extreme 
apex of the wing. Under side exactly similar to that of the male, the brown transverse band on the fore 
wing more strongly indicated than in the male. Expanse, 3.3 in. This species is allied to the E. sophus, 
Fabr., and E. aurora, Auriv., group, but is distinguished from both by its beautiful blue colour. The sexes are 
alike, which is not usually the case in this genus.” 
The following species are distinguished by the green or greenish ground-colour on the underside of both wings. In the 
$2 the apex of the forewing is often white. 
E. aurora Auriv. is only known in the female. The wings are very dark brown above, at the apex of the aurora. 
forewing to vein 5 nearly black; the dark transverse bands are indistinct; the subapical band, which forms 
a spot in cellule 4 also, and the apex of the forewing are white; from vein 2 of the forewing to vein 2 of the 
hindwing runs a very indistinctly defined, bluish violet or bronzy median band; the under surface is dull green, 
in the basal part of the hindwing somewhat darker and beyond the middle interrupted by the thick, somewhat 
lighter rings of the postdiscal spots; as in many other species, a curved, dark olive-brown stripe runs from the 
apex of the forewing to the middle of the hindmargin; in addition to the white markings of the upper surface 
the forewing has a transverse band in the cell and the hindwing a transverse streak in cellule 7. Congo region, 
on the Ubangi River. 
E. wilwerthi Auriv. (41 a, b). The is chestnut-brown above with dark transverse bands and very wilwerth 
similar to the of iturina, but beneath the wings are quite different, dark greenish, in the basal part more 
grey and in the distal more greenish; the distal part of the forewing is proximally bounded by the usual curved 
line; this is continued on the hindwing as far as vein 5 or 4, but is only in cellule 7 thick and sharply de¬ 
fined; at the costal margin of the forewing are placed 2 or 3 not sharply defined whitish grey spots and the 
apex is also more or less grey-scaled. The $ is dark brown above without distinct transverse bands, only the 
submarginal line cpiite distinct, very slightly undulate; the under surface is light greenish grey with white sub- 
apical band on the fore wing and otherwise the same markings as in the from aurora $ it differs in the 
dark apex of the forewing and the entire absence of the metallic median band on the hindwing. Congo to Ituri. 
E. demetra Godt. (41 b). The $ differs from all other species in the black-grey, somewhat glossy ground- demetra. 
colour of the upper surface; the black transverse bands are continuous and distinct; the narrow costal area 
of the fore wing is tinged with bluish; the subapical band is entirely absent; the under surface is bright green, 
somewhat darker in the distal part, the extreme apex of the forewing, a transverse streak in cellule 7 of the 
hindwing and 2 or 3 indistinct spots at the costal margin of the forewing are white or whitish; the proximally 
curved distal area of the forewing on the contrary is not or only indistinctly bordered with white. In the $ 
the wings are uniform dark brown above without distinct transverse bands; the forewing has the apex white 
and bears a narrow, hardly distinct yellow subapical band; the hindwing beyond the middle with a curved, 
anteriorly narrowed, blue transverse band; the under surface is strongly glossy, light slate-grey, scarcely tinged 
with greenish, the apex of the forewing and the narrow subapical band are white, the latter is continued 
posteriorly in a light oblique line as far as vein 7 of the hindwing. Sierra Leone to Cameroons. 
The following five species are very similar above and beneath and agree in both sexes having on the forewing a sharply 
defined subapical band, yellow above, white beneath. The costal margin of the hindwing beneath is alw r ays white at the 
base. They have the peculiarity that the apex of the forewing is sometimes white in both sexes (maximiana, flaminia), some¬ 
times only in the 2 (phantasm, phantasiella), sometimes in neither d nor 2 ( nivaria). The under surface is always bright 
green, often strongly glossy. Instead of repeating the same characters in each species I give here two synopses, by which the 
species can be at once easily determined. 
Synopsis of the 
I. Apex of the fore wing above not white or only with white fringes. 
A. Forewing beneath uniform green, not darker at the distal margin and without dark markings. 
E. phantasia. 
B. Fore wing beneath at the distal margin more or less darkened, olive-green; the dark distal area 
with its proximal margin curved. Wings beneath at least in the cell with more or less distinct dark 
markings. 
a. Wings above with the usual dark transverse bands very distinct. Smaller species, 50—-55 mm. 
E. phantasiella. 
b. Wings above deep black-brown without distinct black transverse markings. Larger species, 60—65 mm. 
E. nivaria. 
II. Apex of the fore wing above white. Both wings above uniform black-brown without or with indistinct 
transverse bands, beneath light blue-green with darker markings in the cell and often also with darker 
transverse bands beyond the middle; between veins 7 and 4 of the hindwing a whitish transverse stripe, 
a. The yellow subapical band on the upperside of the forewing only about 2 mm. in breadth and not 
reaching vein 3. Smaller species, 57-—61 nun. E. flaminia.
