scales in 2 and on the anal lobe, the eye-spot in 2 proximally narrowly bordered with an ochreous yellow; in 
area 1 c there appear two accumulations of metallic scales. Frons white with a yellowish-grey median groove. 
Legs white, above spotted dark. Palpi white, at the tips blackish. Expanse 30 to 31 mm. German East Africa 
near Madibira. 
9. Genus: Trichiolaus Auriv. 
Eyes densely haired. The last joint of the palpi shorter than the second. Forewing in the d with 12, 
in the $ with 11 veins. Hindwing with three small tails (at the veins 1 b, 2 and 3), the last very short. It only 
differs from Iolaus bv the haired eyes.

T. mermeros Mob. d- Forewing above black in the basal part almost as far as the apex of the discal mermeros. 
cell and as far as vein 3 bright blue with a silvery lustre; the blue colour in 1 a to 2 separated from the margin 
by a black marginal band of only 2 to 3 mm width; hindwing above as far as the margin of a beautiful blue, 
areas la, lb, and the costal margin blackish, the black costal-marginal band expanded at the apex, almost 
reaching vein 5, large, black marginal spots in 1 b to 2, that in 1 b with yellow and lustrous scales. Both wings 
beneath blackish-grey; forewing with a fine, short transverse streak bordered with white, at the cell-end, a 
fine black discal line proximally bordered with white, and a submarginal line dissolved into white dots; 
hindwing with two black basal dots surrounded with white, one in the cell and one in 7, a small black dot 
in 1 a, a black discal line being straight at the costal margin and proximally broadly bordered with white, 
and 2 or 3 irregular, white transverse lines in the marginal part; a black dot decorated with golden lustrous 
scales in the anal lobe and a black marginal dot in 2 proximally broadly bordered with orange-red; area 1 c- 
at the margin whitish with two dark nebulous spots. The 2 differs above from the d by the basal part of the 
forewing being blue only in la, lb and the discal cell, in area 2, however, white and smaller than in 
the A: the under surface is somewhat lighter than in the d- Madagascar. 
T. leucoceros Oberth. only deviates by the transverse line of the hind wing beneath being leueoceros 
somewhat bent at the costal margin and in the d towards the base very broadly bordered with white; in the 
2 the basal part of the forewing above is nearly all white, and the ground-colour beneath purely white. Mada¬

10. Genus: Da]mloclig;ma Karsch. 
Eyes bare. Palpi long, almost smoothly scaled. Vertex with bristlj scales. Antennae rather thick with 
short joints and only gradually passing ovei into a circular, little thickened club. Anterior legs especially in 
the d almost to the tips densely long-haired. Forewing with 11 veins and an almost straight margin. Hindwing 
with three small fine tails (at 1 b, 2 and 3), of which that at 1 b is shorter or at least not longer than that 
at 2). Margin of hindwing between the anal angle and vein 3 broadly extended, then angularly incised. 
The species, which is known long ago though very rare, is easily discernible from the allied Iolaus- 
species by the marking of the under surface showing numerous fine transverse lines on a dark ground. In the 
d the hindwing above shows in the middle a large, indistinctly defined, pale yellowish mealy spot. 
D. hymen F. (68 c). d- Forewing above black with a narrow, bluish-white inner-marginal spot covering hymen . 
the basal half or somewhat more than half of the areas la and 1 b and the basal third of the discal cell, and 
ending at the rise of vein 3; hindwing above bluish-white with a small black apical spot of about 2 mm width 
and 5 mm length, and a fine black marginal line; fringes white, at the proximal margin long and brownish; 
the pale yellow mealy spot almost covers the whole discal cell and the base of the areas 2 to 5; forewing at 
the proximal margin with long white hair. Both wings beneath blackish-brown with numerous fine, white 
transverse lines and transverse streaks as is best seen on the figure; hindwing generally before the middle with 
a slanting white transverse stripe from the middle of the costal margin towards the proximal part of the proximal 
margin. The $ differs above by the whole basal half of the forewing being white as far as the costal margin 
and a little beyond the cell-apex and by the black apical spot of the hindwing being much larger. Sierra Leone

11. Genus: Iolaus Hbn. 
To this numerous genus belong the largest and finest representatives of the Lycaeninae in Africa. All 
the species are confined to the African continent (with Fernando Po) and Arabia, and are entirely absent in 
Madagascar, the Comoro and Mascarene Islands, and in the other small islands in the Indian Ocean. A single 
species penetrates into the palearctic region in Palestine. Eyes bare, palpi long, with appressed smooth scales. 
Antennae strong with short, very indistinct joints; towards the apex only very feebly and gradually thickened 
with a circular, not deposited club. Forewing in the d with 11 or 12 veins, in the latter case vein 7 always 
terminates into the margin; in the.2 always with 11 veins and with vein 7 into the apex or costal margin.
