The margin of the hindwing projects somewhat angularly at the anal angle and shows a distinct small 
tail at the end of vein 2. 
The $ is distinguished by the ground-colour above being lighter with distinct black discal spots of 
the forewing. 
Review of the Species. 
A. The proximal submarginal line of the hindwing beneath is not connected with the margin along vein 2. 
The discal spots of both wings are filled up with white, ring-shaped. — rf. Forewing above dark violettish- 
blue without velvety spots or velvety streaks. C. antinorii. 
B. The proximal submarginal line of the hindwing beneath is continued along vein 2 to the margin. At least 
the discal spots of the forewing are not filled up with white. — <$. Forewing above with a large, black 
velvety spot at the end of the discal cell or with separate dark longitudinal streaks in the areas 1 b to 6. 
a. The discal cell of the forewing beneath between the basal spot and the apex with two distinct black 
or brown transverse bands. The discal spots of the hindwing beneath more or less rounded off and separated 
in the centre filled up with white, ring-shaped. 
*. Larger, 35 to 40 mm. Both wings above with a beautiful violettish-blue reflection (<^), or at least 
the forewing for the greater part scaled blue. — <$. Forewing above with a large, black velvety spot 
behind the apex of the discal cell. C. crawshayi. 
**. Smaller species with an expanse of 25 to 30 mm. Both wings above with a coppery brown ground¬ 
colour and without or almost without a violet reflection. 
1. $. Forewing above with a large velvety spot in the centre. 
a. The velvety spot is almost cordiform, covering the discal cell, the basal halves of the areas 
4 and 5 and a great part of the areas 3 and 6 as well as a small part of area 2, but it does not 
reach to vein 2. C. cordatus. 
b. <$. The velvety spot is more elongate and extended posteriorly, so that it reaches to vein 1. 
C. lunifer. 
2. $. Forewing above with 7 separate, more or less elongate velvety spots, two in 1 b, and one each 
in 2 to 6. C. yoggei. 
(3. The discal cell of the forewing beneath between the large basal spot and the apex only with a dark trans¬ 
verse band. The discal spots of the hindwing beneath are quadrangular, more or less united into a transverse 
band and not or only rarely partly filled up with white. 
*. <$. Forewing above with a large, cordiform, black velvety spot between the discal cell and the apex, 
almost entirely like in C. cordatus. C. 7iubifer. 
**. Forewing above in the areas 1 b to 6 and in the discal cell with fine black streaks on the folds. 
The discal spot 2 of the forewing beneath is situate much more towards the base than the spot in 
area 3. 
a. Forewing shorter and broader, entirely as in nubifer; the small tail of the hindwing is about 3 mm 
long. Upper surface very dark brown. C. delatorum. 
b. Forewing somewhat longer and narrower; the small tail of the hindwing is only 2 mm long. Upper 
surface light coppery brown. C. jalkensteini. 
C. antinorii Oberth. has above dark violet forewings bordered with blackish, and bluish-grey hindwings antinorii. 
being darker at the margin and base; it was at first described from Abyssinia, but it occurs in East Africa as 
far as Rhodesia and the Manicaland and was also met with by A. Schultze near Bamenda in Cameroon; $ 
unknown. 
C. crawshayi Bull. (72 k) is the largest species of this subordinate genus and easily recognizable by erau-shay 
the marks stated above; the $ is above in the basal part of the forewing scaled greenish blue, with a transverse 
streak in the discal cell, a large spot at the end of the discal cell, a coherent transverse band of 6 discal spots, 
and the marginal band black or blackish. Nyassa Land. 
C. cordatus Em. Sh. (72 i) has in the above dark coppery brown wings without any other marks cordatus. 
but the velvety spot of the forewing and the two marginal spots of the hindwing being decorated with some 
blue scales. On the forewing beneath the discal spots of the areas 1 b and 2 are absent; $ unknown. British 
East Africa near Kavirondo and Kikuyu. 
C. lunifer Rebel agrees beneath with cordatus and differs above only by the velvety spot of the forewing lunifer. 
being extended posteriorly and reaching to vein 1; it thereby forms a transition to the following species. 
Described according to a single <$ from Bukoba in East Africa.
