B. Margin of the forewing more or less convex, sometimes almost prominently bulging; its apex sharp- 
pointed. — <$. Forewing without a black spot on the under surface at the base of area 1 b. The mealy 
spot of the hindwing above covers the base of the areas 6 and 7, sometimes also a part of the discal 
cell. Wings above as far as, or almost as far as the margin, intensely dark blue or greenish blue. -— 
Diopetes Karsch. 
a. Forewing beneath at the posterior margin at least as far as the fold of the area 1 b whitish; the light 
colour is distinctly defined. 
*. Wings beneath only with whitish nebulous bands or spots, but in the marginal area without 
the 3 or 4 fine, white transverse lines peculiar of the other species of this group. 
D. pasteon. 
**. Both wings beneath in the marginal part with 3 or 4 fine, white transverse lines. 
1. Small species. Veins on the hindwings above black. D. kedassa. 
2. Larger species. U- Veins above not black. D. catalla. 
(3. Forewing beneath at the posterior margin not or only little lighter or only in the area 1 a whitish. 
Both wings beneath in the basal part as far as the first transverse line one-coloured without markings. 
*. The innermost of the three white transverse lines of the forewing beneath is situate in the area 
1 b about 6 mm distant from the margin and is 3 or 4 times as distant from the second as the 
latter is distant from the third. — <§. Wings above dark violettisli-blue, with a slight reflection. 
D. violetta. 
**. The innermost white transverse line of the forewing beneath is situate in the area 1 b only 
3 to 4 mm distant from the margin and at most twice as distant from the second as the latter 
is distant from the third. 
1. Wings above purely blue with a slight reflection. — $. Wings above monotonously brown, 
somewhat lustrous, but without blue or violet scales. D. deritas. 
2. <$. Wings above greenish blue, with a strong reflection and for this reason, on being seen 
perpendicidarly from above, only in the basal half of the forewing blue, but distally blackish. 
— 9- Wings above for the greatest part dull blue, towards the margin blackish. 
D. corruscan-s. 
D. camerona Plotz (65 k). Wings beneath blackish with a fine, white transverse streak in the cell 
near its apex, a similar transverse streak close behind the cell in 4 and 5, 2 white discal lines and two similar 
submarginal lines; the discal and submarginal lines are often interrupted at the veins and usually form a bow 
in each area, so that the bows of the first and third lines are proximally convex, those of the second and fourth 
lines distally convex, the hindwing showing besides a fine white line close at the margin between the veins 
1 c and 5; a black submarginal spot encircled with red in 2; anal lobe above black and red with some blue scales, 
beneath black, towards the base bordered with red. Wings above in the black with blue longitudinal rays 
in 1 b, 4 to 6 and the discal cell of the forewing, and in 1 c, 5 and the discal cell of the hindwing; the latter, 
besides with blue marginal spots in 2 to 4; areas 1 a and 1 b of the hindwing whitish. In the $ the wings are 
above monotonously smoky brown, with a violet hue or scaled blue at the base. Sierra Leone to Cameroon. 
D. diyllus Hew. (66 a, b) is very much like camerona, from which it deviates beside the marks mentioned 
in the review only by the <$ showing the areas 2 to 4 on the hindwing above almost entirely scaled blue with 
black veins, and by the $ exhibiting the wings above monotonously dark smoky grey without a violet hue. 
The species is somewhat smaller than camerona. <$. Pencil at the posterior margin of the forewing beneath 
yellow. Sierra Leone. 
D. kohli sp. n. <$. Forewing above blackish with a dark brown marginal band of 4 to 5 mm width, 
the black colour being almost rectilinearly defined towards the margin and reaching about the middle of the 
areas 3 and 4; the areas 1 a and 1 b as far as the brown marginal band densely covered with scales of a blue 
reflection; the scales of the discal cell and those in the basal part of the areas 2 to 6 are projecting and 
form a large, mealy spot; the posterior margin is before the middle bulgingly expanded. Hindwing above in 
the areas 1 c to 6 and in the discal cell of a bright blue with an indistinctly defined black spot somewhat 
before the margin in the areas 2 and 3; the areas 1 a and 1 b are dark grey, 7 and 8 blackish; a fine, black 
marginal line; anal lobe red, bordered with black; small tail black, at the end white; margin at vein 3 
obtusely rounded off. Under surface dark slate-coloured merging somewhat into greenish; the markings are 
scarcely darker than the ground-colour and therefore only distinctly prominent by the white border-lines; 
a transverse spot at the cell-end, on each side bordered by a fine, white line; the discal transverse band is irre¬ 
gular, formed by square spots and only in the areas 1 b and 1 c of the hindwing decorated with some yellow 
scales; two white submarginal lines; fringes coloured dark; anal lobe of the hindwing beneath black, towards 
the base bordered by a red spot; in the area 2 a large, black marginal spot curled orange-yellow; a fine white 
marginal line is anteriorly indistinct. Expanse of wings: 25 mm. Congo District.
