2. Oemilius Group. 
Wings above black with a common, straight white transverse band, broadly margined with bluish at both sides, 
starting from the costal margin of the forewing beyond the middle and terminating at vein 1 b of the hindwing near the inner 
margin. 
C. oemilius Doumet (34 a). Both wings above in addition to the median band with two rows of oemilius. 
rounded white spots dusted with blue, running parallel with one another and with the distal margin; the me¬ 
dian band of the forewing produced distad along the veins. Costal margin of the forewing in the <$ white 
as far as the cell. The under surface is light green with white median band and rows of whitish spots, be¬ 
tween which the ground-colour is ornamented with small black submarginal dots; cell of the hindwing with 
two fine black rings, that of the forewing with two dentate transverse lines. Old Calabar to Gaboon. 
C. frederica Dist. Of this apparently very rare species only the $ is known. It differs from that of frederica. 
the preceding species in the entire absence of the light spots in the distal part. Instead of these the spots of 
the broad median band show tongue-shaped prolongations almost to the distal margin in the middle of each 
cellule. The under surface is marked as above, but coloured as in oemilius. Old Calabar. 
3. Hyarbita Group. 
The species of this beautiful and rare group are nearly allied and are especially distinguished by having the r^o 
entirely different from the $?. The hindwing in both sexes is uniformly rounded and not produced at the anal angle. The 
distal margin of the forewing in the $ is straight and almost entire, in the y only weakly excised and somewhat undulate. 
— both wings above more or less broadly darkened at the base and the hindwing at the inner margin, then light yellow, 
before the distal margin orange-yellow for a greater or less extent and at the distal margin narrowly darkened. Beneath 
the wings are light yellow with dark brown markings and red-brown median line. The $$ on the contrary all have a black 
ground-colour above, white and blue spots in the cell of the forewing, a white transverse band on the forewing starting from 
the middle of the costal margin and running obliquely towards the distal margin and a broad white or light yellowish median 
band on the hindwing. The black submarginal line is absent or indistinct. 
C. reinholdi Plotz is the largest and most beautiful of the species. J: base of both wings above blue- reinlioldi. 
grey; on the forewing the blue-grey colour reaches vein 2, on the hindwing the apex of the cell, covering 
more than half of cellule 2 and also the base of cellule 3; cellules 1 a and 1 b on the other band are blackish; . 
beyond the middle both wings have an orange marginal band about 9 mm. in breadth, which proximally 
shades into the light yellow ground-colour without any distinct boundary; the blackish submarginal line is 
not thickened at the folds and is separated throughout from the narrow black distal margin. Beneath the 
wings are light brown-yellow, divided by a quite straight red-brown median band, which is black in cellules 
lb and 2 of the forewing; the basal part is uniformly coloured, only with distinct black transverse markings 
in the cells, at their apices, in cellule 1 b of the forewing and in cellule 7 of the hindwing; in the distal 
part the postdiscal spots and the submarginal line are only weakly indicated. The $ is very similar above 
to the $ of hyarbita , but has a pure white transverse band on the forewing, reaching vein 2 and in cellule 2 
further removed from the distal margin; beneath the ground-colour of both wings is light brown-yellow 
and the hindwing has a nearly straight rust-brown transverse line which crosses the white median band; 
this transverse line is entirely absent in hyarbita $ — Cameroons. 
C. hyarbita Hew. (36 a) differs in the $ from reinholdi in having the basal part of the upper surface hyarbita. 
black instead of blue-grey; the black colour covers cellules 1 a—2 but not the base of cellule 3 on the hind¬ 
wing and is posteriorly united with the narrow black marginal line; the submarginal line is absent or only 
indicated by dots. Beneath the wings are much darker and more varied than in reinholdi, having a median 
line, which is distinctly curved on the hindwing, and in the basal part of the hindwing a broad, black-edged, 
chestnut-brown curved band, while the distal part of the hindwing from the inner margin to vein 5 is dark 
brown. The $ (36 a) has a whitish transverse band on the forewing, not quite reaching vein 2, but in cellule 2 
extending nearly to the distal margin, and beneath is entirely without the brown transverse line of the hind¬ 
wing. -— Old Calabar and Cameroons. 
C. hyarbitina Auriv. (35 b) is smaller and darker, but otherwise very similar to the preceding species hyarbitina. 
and perhaps only a local race of it. The $ (35 b) differs from that of hyarbita in having the base of both 
wings above dark grey, cellules 1 c—3 on the hindwing dark brown, irrorated with black, and especially 
in having the submarginal line entire and at the inner angle strongly thickened; the distal margin is also 
much more broadly darkened than in hyarbita. The under surface agrees almost entirely with that of hyarbita 
S, but is somewhat lighter and has a distinct submarginal line. The $ is very similar to that of hyarbita, 
but smaller and with the median band of the hindwing only about 8mm. in breadth; the ground-colour beneath 
is more yellow-brown. Congo region, on the Sankuru River. 
C. beckeri H.-Schaff. (= theodota Hew.) (34 c). <$: wings above light yellow, at the base bluish beckeri. 
grey; costal margin and a very broad marginal band on the forewing orange-yellow; hindwing with very
