Third Group of Species. 
Frons as in the species of the second group black with white lateral margins. Legs also white, but with, 
distinctly prominent black rings or spots. Anal lobe of hindwing above black and white with some metallic 
scales, but without any red. In all the dd known the forewing only shows 11 veins. The mealy spot on the 
hindwing above is surrounded by a large, lustrous dark zone. Hindwing above with a fine, black marginal 
line sometimes a little widened at the apex of the wing. 
Wings beneath white and in all the species with almost quite the same markings; forewing beneath 
with two widely separated, blackish-grey postmedian lines which are continued on the hindwing as far as 
vein 3 and are often little distinct; hindwing then between veins 3 and 1 a with a thick, irregular reddish- 
yellow or red transverse band which is parted by a metallic lustrous greenish or silvery line; in addition a 
black submarginal dot in area 2 and at the anal angle. As the $ is only known of one species, the following 
review only refers to the AcC 
Review of the <$. 
A. The blue colour of the forewing above almost covers the whole discal cell and also the base of the areas 
2 and 3. 
a. Wings above light blue with a distinct green reflection. I. bellina. 
(3. Wings above deep blue without a green reflection. 
*. Forewing at the anal margin very much and broadly sinuate. Mealy spot of the hindwing very large. 
I. sappirus. 
**. Forewing at the anal margin with a smaller indentation. Mealy spot of the hindwing smaller. 
I. gemmarius. 
B. The blue colour of the forewing above is very much reduced, covering the basal half of the discal cell at 
most and leaving the areas 2 and 3 entirely (or almost entirely) free. 
a. Forewing beneath as far as the proximal transverse line darkened (the distal line indistinct). The distat 
transverse line on the hindwing beneath towards the apex of the wing thickened and reddish-yellow. 
Hindwing above without a black apical spot. I. sapphirinus. 
[3. Hind wing above with a black apical spot. The distal postdiscal line on the hindwing beneath at the 
costal margin neither red nor expanded. I. sciaphilus. 
I. bellina Plotz (= iaspis Drc.) (68 d). We have only to add to what has been said above that the 
hindwing above generally shows two black spots in area 1 c; these spots are much larger in the $ and separated 
by a white spot. The $ differs besides from the by the blue colour being less extensive and of a greyish 
tint; costal margin of hindwing as far as vein 5 black. Sierra Leone to Cameroon. 
I. sappirus H. Drc. (68 d) only deviates from bellina, as the figure shows, by the marks stated 
above. Sierra Leone. 
I. gemmarius H. Drc. (68 d) is probably only a race of the preceding species. Cameroon. 
1. sapphirinus Auriv. (= aurivillii Bob.) (68 e) is easily recognizable by the shape of the blue area of 
the forewing. Gabun on the Ogowe River. 
1. sciaphilus Schultze (68 e). I have not seen. The description says: on the forewing above jet-black 
with a large, bright, light greenish-blue basal spot (of the same extent as in sapphirinus ); hindwing above with 
a bright light greenish-blue ground-colour, areas 1 a and 1 b black, from the proximal margin to vein 5 a fine 
black marginal line, then a large, jet-black costal-marginal spot; scent-spot very large, filling up the whole 
cell except a small, blue basal spot; in area lea black spot cohering with the proximal margin and towards 
the base from it a sagittiform spot on vein 2. likewise connected with the proximal margin by a broad black 
streak; anal lobe black, posteriorly white, mostly with some metallic green scales; scent-spot lustrous grey, 
in the centre with very much upturned, golden brown scales. Beneath as in I. bellina, except the metallic median 
line of the hemochrome spot being continued on the anterior side of the orange colour towards the anal lobe. 
The 2 differs from the $ by the discal cell of the hindwing above being scaled blue and the hindwing showing 
a small, short tail at vein 3. 24 to 28 mm. Cameroon in the district of the Upper Cross River. 
Fourth Group of Species. 
To this group I place all the species in which the frons is above more or less yellow or reddish-yellow 
and the forewing beneath marked as in the three first groups. Most of the $$ being unknown, I must 
here likewise contrict myself to the <$<$ in the review of the species.
