B. Wings beneath in the basal halves at least with one transverse streak at the end of the discal cell and 
with a dot in area 7 of the hindwing. The small tail of the hindwing always shorter than the hindwing 
itself. 
a. Forewing beneath without markings between the base and the transverse streak at the end of the discal 
cell. Eyes hairy. Third group. 
(3. Forewing beneath in the middle between the base and cell-end with a reddish-yellow transverse streak 
continued also on the liinclwing to the proximal margin. Eyes bare. Wings in both sexes above mostly 
blue. — Hemiolaus subgen. nov. Fourth group. 
First Group. 
Forehead black or blackish with white lateral margins. The wings above are in the S6 more or less 
reflecting blue, in the $$ blackish-grey or blackish-brown with white spots at the anal angle or before the margin 
of the hindwing. The d'd' usually without a hair-pencil and mealy spots, rarely with a minute mealy spot at 
the base of area 2 and vein 1 of the forewing above. 
Review of the Species. 
A. The discal band of the forewing beneath is at the posterior margin much farther distally removed than 
the discal band of the hindwing and therefore does not converge with the latter, but with the submarginal 
line of the hindwing. The black spot scaled greenish in the anal lobe of the hindwing beneath without any 
red bordering. 
a. <$. Forewing above with a faint blue reflection; hindwing above without white spots in the areas 2 and 3 
or only with a small marginal spot in area 3. $. Wings above with a blackish-grey ground-colour. Hind- 
Aving above at the margin as far as vein 3 or 4 with 2 (or 3) Avhite bands. H. hatita. 
(3. Forewing above blackish; hindwing above with a white spot in area 2 about 3 mm distant from the 
margin and with two white spots in area 3, the proximal one being much smaller or indistinct. — $. 
W T ings above with a faint bluish-violet reflection. $. Wings above without a blue reflection. 
H. nigra. 
B. The discal band on the forewing beneath is always situate exactly in the prolongation of the discal band 
of the hindwing. The black spot of the anal lobe of the hindwing beneath towards the base and towards 
vein 1 b bordered by a red spot. 
a. A larger species with an expanse of 28 to 29 mm. — Forewing above in the basal half faintly greyish- 
blue with a slight reflection; beneath as far as the posterior margin white. H. antifaunus. 
(3. Smaller species with an expanse of 20 to 24 mm. — rf. Forewing above black, at least as far as the 
middle with a blue or greenish reflection, beneath at the posterior margin in the areas 1 a and 1 b 
extensively covered with black; above at the base of vein 1 with a narrow, strigiform, mealy spot covered 
with brown hair. 
*. The white proximal margin of the hindwing above is very broad, penetrating more or less into the 
area 2, where it is in the $ covered with blue. — Forewing above without a mealy spot in area 2. 
H. lebona. 
**. The white proximal margin of the hindwing above is narrower and anteriorly bordered by vein 2. — 
J. Forewing above in the angle between vein 2 and the median with a minute, triangular, brown, 
mealy spot. A. dubia. 
H. hatita Hew. (68 b). $. Wings above blackish with a blue reflection, particularly on the hindwing; 
the hindwing at the proximal margin as far as vein 2 grey and white with a white submarginal spot in 1 c. 
$. Wings above blackish-grey without a blue reflection; the transverse lines beneath showing through as 
dark lines; hindwing with Avhite marginal spots in 1 c and 3 and white submarginal spots in 1 c to 3. To the 
description of the under surface mentioned above we may only add that the forewing is rather broadly darkened 
at the margin. Sierra Leone to Angola and Congo District. •— ugandae E. Sharpe is unknown to me and some¬ 
what indistinctly described, but it seems only to differ from the type by the wings beneath being white as far 
as the margin without a dark marginal band. Uganda; Kiwu and Ukerewe. 
H. nigra Ham. Druce (68 b) was already figured by Heavitson as hatita (fig. 23), but it was only 
in this year established as a separate species by Druce. It is easily recognized by the white spots of the areas 
2 and 3 on the hindwing above. Larva green, shaped like a wood-louse. Sierra Leone to Cameroon. 
H. antifaunus Dbl. & Hew. (-6M)). Both wings above in the basal half as far as the discal band 
showing through from beneath distinctly covered with a greyish blue; hindwing above with the same white 
spots as in nigra-ft. The $ is above similar to the d\ but somewhat lighter. The under surface is described 
in the review. Sierra Leone to Angola and Uganda.
