H. lebona Heiv. (67 a, 68 b). Both wings above as far as beyond the middle dark blue, at the lebona. 
margin broadly black; the proximal margin of the hindwing as far as or almost as far as vein 3 scaled white 
or light blue. Under surface marked almost exactly as in antifaunus. Sierra Leone to Congo and Toro. — 
The larva is of a bright green, the opening of the dorsal gland encircled by red; it is visited by ants of the 
genus Pheidole. — ab. scintillans Auriv. only deviates by the $ wings being black on being seen from above, scintilla ns. 
with a blue reflection on being very slantingly seen from the side. Cameroon. — ab. caerulea Auriv. has the caerulea. 
black marginal band of the forewing only about 2 mm broad and almost equally broad; the hindwing above 
almost as far as the margin blue, only at the apex narrowly black. Cameroon. 
H. dubia Auriv. (68 b) is very much like the preceding species; the differences are stated in the review dubia 
of the species. In the $ the wings are above black, as far as beyond the middle with a very dark blue reflection. 
In the $ the wings are above blackish-grey without a reflection; hindwing in 1 a and 1 b white and with white 
spots in 1 c, 2 and 3, and a fine, white marginal line from the anal angle to vein 4. Cameroon. 
Second Group. 
The two species of this group are closely allied to those of the preceding group and only differ by the 
shorter small tail at vein 1 b of the hindwing. In the <$ the forewing above has at the end of the discal cell 
a distinct, rounded, grey mealy spot covering the bases of the veins 3 to 5; both wings above at least in the 
basal part blue; the costal and distal margins of the forewing black. The under surface in both sexes coloured 
and marked almost exactly as in H. antifaunus. 
Review of the Species. 
1. The anal lobe of the hindwing above spotted red. Wings above in the basal parts greyish-blue. 
H. liar a. 
2. The anal lobe of the hindwing above black without red scales. Wings in the d above azure-blue. 
H. naara. 
H. liara Ham. Druce (67 a). Hinclwing above with a dark discal and submarginal band. — d- Wings liara. 
above black; forewing in the basal third scaled light greyish-blue; hindwing from vein 4 to the proximal margin 
scaled light bluish-grey. In the $ both wings are above in the basal halves covered with a bluish-grey; the 
areas 1 b to 4 of the hindwing are decorated with two transverse rows of white spots and a white marginal line. 
Ashanti to Congo, Uganda and Kavirondo. 
H. naara Hew. (67 a). d- Wings above of a beautiful azure-blue; the costal and distal margins of naara. 
the forewing narrowly black, only about 1 mm broad; hinclwing with a fine, black marginal line and white 
fringes. $ unknown. Angola. 
Third Group. 
Both wings beneath show a distinct transverse streak at the end of the discal cell, and the hindwing 
besides a dot at the base of the area 7. The eyes are hairy and the small tails of the hindwings rather short 
and almost equally long. The dd have no hair-pencil nor mealy spots. 
Some species which I place in to this group are unknown to me and insufficiently described, and it 
is therefore possible that they do not belong to this group. 
Review of the Species. 
A. Wings above with a black, dark brown or grey ground-colour. 
a. Both wings above black. Hindwing with some blue scales in the fold and on the anal lobes. Fringes 
of forewings black, of the hindwings white. H. moyamibina. 
(b Wings above dark brown with a violet or coppery lustre (d) or in the $ grey or blackish-grey with white 
markings at least on the hindwings. 
*. The discal band beneath on both wings similarly developed and moderately broad. 
§. Forewing on both sides or at least beneath at the costal margin broadly golden yellow or orange- 
yellow. H. auricostalis. 
§§. Costal margin of the forewing not coloured yellow. 
o. The transverse streaks at the end of the discal cell on the under surface are grey or blackish, 
filled up with white, rarely on the forewing with a narrow, brown streak.
