C. rosa Hew. (— mafiae Stgr.) (49 a) is to some extent intermediate between jjechueli and amulia ; it rasa. 
differs from the preceding in having on both surfaces of the forewing only 4 postdiscal spots (in cellules 5—8), 
of which the posterior one is usually much larger on the underside than the rest; the yellow markings on the 
under surface of the hindwing are usually lighter and more confluent than in r pechueli. In the $ the dark 
markings on the upperside of the forewing stand out more strongly and the distal margin is more or less broadly 
darkened. Delagoa Bay; Portuguese, German and British East Africa. 
C. amulia Cr. (49 a). The upper surface in the <$ is unicolorous dark copper-brown with violet reflec- amulia. 
tion, without markings; in the $ on the other hand there is a dark spot at the apex of the cell and a lighter 
transverse band behind the cell on the forewing and the hindwing has distinct postdiscal dots. Beneath 
both wings are bright ochre-yellow with almost exactly the same markings as in rosa, but with the grey-blue 
rings and spots even more reduced. Sierra Leone to Angola. 
Second Group. 
Forewing narrower and more pointed than in the species of the first group and with the distal margin more or less 
deeply emarginate. The under surface of the forewing is often more or less yellowish, but not bright orange-ye)low, and the 
hindwing has a grey or brownish ground-colour beneath. 
C. occidentalium Mob. (48 g). In the the wings are nearly black above with a broad brownish occidenta- 
marginal band on the hindwing, in which the postdiscal eye-spots stand out more or less distinctly; in the $ hum. 
this band has a grey reflection and is continued oil the forewing as far as vein 6, but narrowed, the forewing 
has in addition a red spot at the apex of the cell and three small light spots at the costal margin midway 
between the cell and the apex. The under surface is almost alike in both sexes; the forewing glossy yellow- 
brown (o) or brown-yellow ($) with broad black transverse band behind the cell between the costal margin 
and vein 3 and grey apex; the hindwing grey with blackish markings. Sierra Leone to North Angola and Abys¬ 
sinia. — penricei Rothsch. & Jord. only differs in having the ground-colour on both surfaces lighter and the penricei. 
subapical black transverse band on the underside of the forewing smaller. Angola. 
C. morantii Trim. (48 g). Both wings in the A unicolorous dark grey above without markings, in the morantii. 
$ the hindwing is faintly tinged with yellowish in the marginal part and the forewing is blackish in and behind 
the apex of the cell and has some light spots hi and behind the black colour. The under surface is similar 
to that of C. occidentalium, but much lighter. The species nearly approaches the preceding, but is considerably 
smaller and lighter coloured. Natal and Nyassaland. 
C. boisduvali Wallengr. (48 g) is a small, dark species. In the $ the wings are dark brown above, boisduvali. 
before the distal margin of the hindwing more or less relieved with yellow-broivn and with black postdiscal 
dots in cellules 2—6; in the $ both wings are lighter and the forewing has at the costal margin the usual 
yellowish discal and subapical spots of the $. The underside of the forewing in both sexes is yellow with 
grey apex, black subapical band and 1 or 2 black spots at the apex of the cell; the underside of the hindwing 
is distinguished by its chequered colouring of brown-grey, white-grey and black, the rings of the eye-spots 
stand out distinctly and are brown or only slightly yellowish. — The larva lives in Natal on Excoecaria reti¬ 
culata, a common tree there. It has a dark brown head and is laterally light brown and dorsally rust-brown; 
each segment bears six short black spines with fine bristles; the spines of the 10th to 12th segments are 
distinctly branched. Pupa light brown with darker markings; its head has two obtuse points. The species 
is distributed from Sierra Leone to Natal, Brit. East Africa and Uganda and is common in Natal. — kaffana kajfana. 
Rothsch. & Jord. only differs on the under surface in the darker ground-colour of the forewing and the more 
uniform, olivaceous ground of the hindwing. Abyssinia. 
C. dubiosa Strand is unknown to me and is described as follows: “Above about as boisduvali Wallengr ., dubiosa. 
dark brown with slight olivaceous gloss, occasionally perhaps almost pure black; fringes with very slight 
pale greyish gloss, on the forewing with traces of whitish spots; this wing is a little darker in the cell and the 
costal area than posteriorly; beneath it is ochre-yellow with grey-brownish margin and a large black spot between 
the cell and the apex, as well as a smaller spot in the cell itself at the discocellular; the distal and larger 
of these spots is 4mm. in length, fully as broad, and connected posteriorly with the discocellular spot; towards 
the costal margin in particular fine blackish subterminal spots or streaks are present. The apex of the fore¬ 
wing beneath and on the underside of the hindwing the basal half and the eye-spots violet, the latter 
narrowly bordered with greyish and with darker pupils; the posterior half grey-brownish, slightly olivaceous 
and with a violet-tinged marginal band about 2mm. in breadth; the eye-spot in cellule 4 is only half as large 
as the others and bears no black pupil, the one in cellule 7 is also somewhat smaller than the rest, but other¬ 
wise like them; in the basal area are placed in a transverse row 3 black lines, basally convex, lighter-marked 
proximally. The species is no doubt nearly allied to morantii Trim, and possibly only a variety of it”.
