E. nigra Baker. Both wings above blackish-brown (<$) or brown ($). Hindwing unmarked; forewing nigra. 
in the <$ feebly scaled blue at the posterior angle of the cell and in 1 b and 2, in the $ unmarked. Wings beneath 
dull greyish-brown ($) or ochreous-yellow ($) without any other marking but the black longitudinal stripe 
of the forewing. 41 to 43 mm. Sierra Leone. 
E. adolphi friderici A. Schultze (65 b) Forewing above dull black with a faint bluish reflection; adolphi jri- 
in the areas 1 to 4 an anteriorly strongly narrowed median band formed of bluish-white, not distinctly defined 
discal spots, not filling up the bases of the areas; at the end of the discal cell a small, faded, bluish-white spot; 
of the same colour is a subapical band composed of single spots in the areas 4 to 6; beneath dull black with 
the corresponding markings above, which, however, are somewhat more extensive and of a dirty yellowish- 
white colour; the subapical band passes through the densely white-dustecl veins and interneival folds into the 
margin. Hindwing above white, at the base dusted with a greyish blue and with a black marginal band of 5 to 
6 mm width; the veins are more or less dusted black; beneath dirty yellowish-white, at the margin dusted 
blackish; this dark marginal band is radiately interrupted by the black veins bordered with white and the 
broad, white dusting of the internerval folds; terminal vein of the discal cell distinctly dusted black. In the 
$ all the white markings are more extensive and somewhat more distinctly defined. Dr. Arnold Schultze 
found numerous, newly emerged specimens of this species in the primeval forest near Yukaduma in South 
Cameroon. The pupal integuments were brown with black macular markings and, in their shape and the way 
of the fastening of the radiatingly projecting wreath of bristles at the anus, they resembled the pupae of Hewit- 
S 07 iia. The pupae were arranged in small colonies on the under surface of leaves. 
E. ernesti Karsch (65a). <$. Wings above dull blue with a somewhat silvery shade; hindwing with cmesti. 
a dark grey costal-marginal band of 1 y 2 mm width extending in a flat bow through the anterior apical half 
of the cell to vein 3, then to the middle of area 1 b parallel with the margin and finally slantingly to the posterior 
margin, where it is only 2 mm broad; posterior margin long-haired; fringes white. Hindwing above v/ith a 
grey costal margin of 4 mm width and a marginal band of 2 mm width, ending pointedly in the area 2; anal 
angle extended into a point. Both wings beneath silvery white with a light yellow costal margin and black 
marginal dots at the ends of the veins. In the $ both wings are above white, at the bases dusted blue; forewing 
at the costal margin, apex and distal margin broadly blackish-brown; hindwing w ith a blackish-brown marginal 
band ending into a point behind at vein 2; wings beneath purely white, at the costal margin of the forewing nar¬ 
rowly ochreous-yellow and at the distal margin faintly dusted brownish. Togo Land. 
28. Genus : Hewltsoaiisa Ky. 
The Hewitsonia are large and beautiful Liptenins with a very peculiar marking beneath. The forewing 
is beneath blackish-brown, the costal margin as far as the footstalk of the veins 7 to 9 and a very large apical 
spot yellowish with black veins and black streaks on the internerval folds. Hindwing beneath light yellowish 
or almost white with dark longitudinal streaks at the margin, covering either the veins or extending closely 
near to them and being inwardly combined by twos in the shape of arches; besides there are dark streaks at 
the margin on the internerval folds and 6 dark transverse lines, the two first of which extend directly from 
the base of the wing towards the costal margin, whilst the 3 following ones begin near the proximal margin, 
the last one extending between the posterior angle of the cell and the costal margin; the fourth is always the 
shortest and extends only from vein 1 b to the beginning of vein 2; the transverse lines are more or less irre¬ 
gular and sometimes broken up into dots or streaks. 
Above the sexes are not at all alike. In the the forewing shows blue spots at the anal angle in the 
areas (la), lb and 2, and a bluish-white subapical band of 4 to 5 spots of the areas 4 to 6, 9 and 10, in 
the 9 the subapical band is yellow, and at the anal angle there is only a yellowish spot in 1 b or in 2. The hind¬ 
wing is in the <$, at least in the marginal part of the areas 2 to 5, blue, whilst in the $ it is one-coloured dark 
brown without any marking. 
The larvae are long-stretched with long, lateral hair-pencils. Pupae rather stout and squat, 
in the abdominal region above very concave; sides with a sharp margin; dorsum with short, stiff bristles; 
at the anal end surrounded by the radiately extending, long hair of the shed larval skin, the separate 
ventral joints with long, fine, black hair negotiating the transition between the pupa and the hair of the 
larval skin.
