much nearing it. Both wings above and beneath without a spot or transverse streak at the end of the diseal 
cell. Ground-colour in both sexes beneath and generally also above white. Forewing always above with a 
black marginal band expanded at the apex; hindwing with a dark apical spot, black marginal spots, and a 
fine black marginal line; often also with a dark submarginal line. 
Review of the Species. 
A. Hindwing at vein 2 tailed. 
a. Hindwing beneath with black subbasal dots in the cell and in 7 sometimes also in 1 a, but not in 1 c. 
Discal spots 1 c to 6 dull, strigiform, that in 7 large and black. 
*. Wings above in the q with a greyish-blue ground-colour. C. bibundanus. 
**. Wings above with a white ground-colour. 
1. Forewing above at the base with a greyish-blue or bluish spot almost reaching to vein 2 and the 
centre of the costal margin. C. rutshurensis. 
2. Forewing above at the base not or very little darkened. C. plurilimbatus. 
( 8. Hindwing beneath without any subbasal dots. 
*. 'Hindwing beneath with a distinct black discal spot in area 7; the discal spots in 1 c to 6 are dull, 
strigiform, indistinct or absent, very much nearing the submarginal line. Hindwing on both sides 
with a distinct, often thick submarginal line proximally bordering on the marginal spots. 
1. Forewing above at the costal margin broad blackish-grey, usually as far as the marginal band. 
Hindwing beneath without a discal spot in 1 b. C. punctatus. 
2. Forewing above at the costal margin only at the base a little dusted dark. Hindwing beneath 
with a black discal dot in area lb. C. pseudopunctatus. 
**. The discal spot in area 7 of the hindwing is indistinct and pale or entirely absent. The other discal 
spots are absent or very indistinct. 
1. Hindwing on both sides and forewing beneath with a distinct dark brown submarginal line 
proximally bordering on the marginal spots. 
a. Forewing above at the costal margin as far as the centre or as far as the marginal band dusted 
with blackish-grey. C. bueronicus. 
b. Forewing only at the base feebly dusted grey. C. albicosta. 
2. Hindwing on both sides and forewing beneath without a submarginal line at all. The marginal 
spots are therefore quite separate. Forewing above at the costal margin all white, or only slightly 
darkened close at the base. C. giissfeldti. 
B. Hindwing without the small tail. —- Athysanota Karsch. Hindwing beneath without siibbasal dots, but 
with a black discal spot in area 7. The submarginal line on both wings beneath is indistinct or absent. 
Only the three marginal spots 1 c to 2 on the hindwing beneath are black and distinct. C. ornatus. 
As the species have already been dealt with at large above in the characterization of the group and 
in the review of the species, it suffices to mention their range in the following descriptions. 
C. bibundanus Grilnb., by the ground-colour above forms a good transition to C. togara Plotz. $ unknown, bibundanus. 
Cameroon: Bibundi. 
C. rutshurensis Joic. & Tcilb. was described after some A <$ from Ruwenzori is before me and rutshurcn- 
only differs above from the $ by the veins of the hindwing being black only behind their centre and the discal SiS - 
streaks being more indistinct. The under surface of the <$, according to the description, entirely agrees with 
that of the Rutshuru River. Ruwenzori. 
C. plurilimbatus Karsch (= trypherotus B.-Bak.). Baker’s description of trypherotus exactly fits plurilimba- 
plurilimbatus and is certainly the same species. Congo District: Mukenge and Makala. — A questionable $ tl(S • 
of this species I have mentioned and described in dealing with the Lycaenidae of the second German Central 
African Expedition. 
C. punctatus Dew. (74 i; under surface as pseudopunctatus) is above distinguished by the prominent punctatus. 
marginal bands on both wings and the almost invariably complete costal-marginal band of the forewing. 
Lamborn discovered the larva in Nigeria and describes its habits at large. It lives in the flower-buds of Costus 
afer (Scitamineae) and is infested and protected by ants. The pupa also rests in the dry flower-buds. 
C. pseudopunctatus Bird, is unknown to me. The description says: ,,Very similar to the preceding pseudopunc- 
species ( punctatus ), but distinguished by the costal area of the forewing being in the centre not at all and at
