narrow from the costal margin to vein 4, becomes broader in cellule 3, then bends round towards the hind- 
margin and reaches vein 1, but in cellules 2 and 1 b is divided by a transverse shade into two branches; 
hindwing above with traces of three lighter transverse lines; the under surface scarcely different from that 
of cinaethon $. 
Fifth Group. 
The species of this group may be known at once by the markings of the under surface. This is quite similarly 
marked in all the species and only differs somewhat in the lighter or darker ground-colour. The hindwing beneath has a 
straight black-brown transverse band, 2—3 mm. in breadth, which extends from the anal angle (extremity of vein lb) to 
the costal margin somewhat beyond the middle and is then continued on the forewing in a gentle curve as far as the apex, 
but is sometimes indistinct anteriorly; the submarginal line of both wings is distinctly though weakly undulate or dentate, 
before it a transverse row of black dots: before the transverse band on both wings an irregularly sinuous median line, 
which on the forewing runs almost as in ikelemba (41e); in the cell of the hindwing are placed 2 or 3 dark ring-spots and 
before them a similar ring in cellule 7; all these rings stand in a straight line; the ring-spot in cellule 7 otherwise occurs, 
but more indistinctly, only in the species of the fourth group; on the forewing there are also 3 dark rings in the middle 
of the cell and behind them 1 or 2 similar rings in cellule lb. The sexes are very dissimilar above, the nearly al¬ 
ways darker and with more distinct dark transverse bands; of the typical dark transverse bands the first is entirely absent 
or only weakly indicated; the second is well developed, at least on the forewing, and is sharply dentate at veins 4 and 5; 
the third is more or less indistinct, shadowy, and little darker than the ground-colour, but at the costal margin of the 
forewing much widened in cellules 5 and 6; the fourth always consists of free, rounded, often light-margined spots and 
the fifth forms a distinct submarginal line; between the second and third transverse bands there is at the costal margin 
of the forewing in the $ always a white subapical band and in the $ often a yellow one.

only the second transverse band and some sinuous transverse lines in the cell of the forewing black and very 
distinct; the subapical band of the forewing wanting; the postdiscal spots of the forewing sometimes with 
indistinct yellowish rings. The $ is dark olive-brown above, at the apex of the forewing blackish; the 
subapical band in cellules 6—4 white and sharply defined, then in cellules 3 and 2 yellowish and not sharply 
defined; the postdiscal spots are small and bordered with white or yellowish dots; the hindwing yellowish 
beyond the middle as far as the submarginal line. Gold Coast.

line of the forewing on veins -4 and 5. In the $ the wings are dark red-brown or chestnut-brown above, with 
distinct black markings, only the third transverse band is scarcely darker than the ground-colour and hence 
only shows up at the costal margin of the forewing where it is light-bordered; the yellow subapical band of 
the forewing is very narrow (about 1 mm. in breadth) and is only present as a yellow bordering to the distal 
side of the second band in cellules 3—6; the postdiscal spots are large and rounded and at least on the forewing 
margined with orange. The $ differs from the other species in the light upper surface; the basal part is 
light brown-yellow and distally shades gradually into the whitish ground-colour of the distal half; the dark 
markings as in the <$; both wings darkened at the distal margin. Cameroons to Congo. 
E. niardania F. (40 c, d). In the $ the hindwing and the basal half of the forewing are dark red- mardania. 
brown and the apical half of the forewing blackish with broad, sharply defined yellow subapical band; 
the postdiscal spots are on the forewing more or less distinctly ringed with yellow or whitish and on the hind¬ 
wing posteriorly indistinct; transverse bands 2 and 3 are suppressed or very indistinct in the red-brown 
part. In the $ the hindwing and the basal half of the forewing are brown-yellow and the apical half of the 
forewing black with broad white subapical band and white rings or marginal spots to the postdiscal spots; 
in the brown-yellow colour only the submarginal line and the postdiscal spots of the hindwing stand out dis¬ 
tinctly. — Pupa glossy green with yellowish dorsal spine and transverse band on the third abdominal seg¬

Sixth Group. 
Wings beneath with a common, broad, dark transverse band, running from the apex of the forewing to the middle 
of the inner margin of the hindwing and very irregularly defined; frequently this transverse band is indistinct or scarcely 
more than indicated, but in the last species it is very sharply expressed. The species are large and are distinguished by 
having the ground-colour only present between the confluent black transverse bands of the forewing as separate light 
spots-white or whitish, rarely yellow. The sexes are similar.
