C. tholloni Bouv. Separated from herilla by black, not brown antennae, and stronger dents at tholloni. 
the distal margin of the fore wing. Fore wing traversed by 2 deep brown lines, the interior line with a convex 
bow inwards below the cell, the exterior line parallel to the distal margin, strongly notched, also in the apex 
projecting correspondingly distad. Behind it somewhat pink, also at the base as far as the cell-end, behind 
it paler, greyish-pink, at the cell-end whitish, where it is straightly cut off, to the inner margin with brown 
spots. Hindwing smoky brown, at the base somewhat pink, then white as in herilla. Beneath on both wings 
only the exterior line is distinct. $ 70 mm. Congo. 
C. trefurtlii Strd. (58 c). Forewing dark brown, with a slight violet hue. The two lines are distinctly Irefurthi. 
blackish-brown, the interior line in front vertical, below the cell, obliquely inwards to vein 2, then again vertical. 
Exterior line incurved at the costal margin and thicker there, otherwise parallel to the distal margin. Around 
the cross-vein a greyish-yellow spot. In 2 of 4 specimens on hand the anterior portion of the interior line is 
more oblique, almost parallel to the exterior line. Marginal area lighter, greyish-yellow. The whole wing is 
uniformly striated dark. Hinclwing at the base and costal margin pink, otherwise somewhat lighter than the 
fore wing. Exterior line only distinct in the posterior half. Margin variably lighter. 75—90 mm. East Africa, cumeru- 
— camerunensis Strd. differs at most in its somewhat darker colouring, the difference in the antennal tips mentioned nensh 
by the author is wrong. Cameroon. 
C. lichenodes Holl. Olive grey, striated greyish-green. At the apex and at the centre of the distal lichenodes. 
margin pale ochreous-brown. Interior line deep black, interrupted, strongly excurved towards the centre of 
the inner margin. Another line is not mentioned in the description. Apical third brown with black undulate 
lines. Hinclwing at the costal margin narrowly pink, otherwise brown, at the distal and anal margins with 
black streaks and scales. A black notched line from the anal margin near the anal angle to the distal margin. 
$ 55—60 mm. Benito District. 
C. nenia Westw. (58 d). Forewing of <$ at the apex produced, distal margin of both wings sharply nenia. 
dentate. Wings of $ entirely margined, at the apex rounded off. Forewing at the base and in the anterior 
half violettish-brown. The thick interior line is slightly undulated. The exterior line projects strongly at veins 
6 and 7, as far as vein 4 inwards, then parallel to the interior line. The posterior half of the discal area and 
the distal area nut-brown, at the anal angle yellowish. At the cross-vein greyish-yellow. Hindwing similar 
to trefurtlii, in the inner portion dusted with yellowish-brown. Beneath the exterior line of the forewing is 
much steeper and more distinct as far as the costal margin. Ground-colour of forewing as far as the exterior 
line violettish-brown, in the basal area excepting the margins milky white, beneath the latter below the costal 
margin not notched. At the cross-vein a yellowish-brown spot. Hindwing blackish-brown, on the fore wing 
a similar large discal spot. 40—60 mm. Senegal, Cameroon. 
C. ansorgei Rothsch. (58 d). In the ground-colour similar to nenia, but the forewing not with ansorgei. 
apex, distal margin not notched, only slightly incurved. Hind wing only at the base red, costal margin longer, distal 
margin feebly dentate. Described before the following species, but presumably only a feebler form of it. Angola. 
C. bilineala Rothsch. $ in the shape of the wings more similar to nenia. Forewing with 2 lines, also bilincata. 
the exterior line distinct, before it from the yellowish-grey cellular spot to the costal margin blackish. The 
distal area of both wings less densely blackish-brown. Hindwing at the costal margin more intensely pink. 
It may be the same species as trefurtlii and would then have the priority. $ similar to the <$, but with broader 
wings. On the forewing without a black postcellular shadow. Hindwing lighter than in <$, without a white 
basal area. East Africa. - 
C. ducorpsi Fleur y. <$. Shape of wings as in ansorgei. Ground-colour of fore wing mouse-coloured ducorpsi. 
with a pink hue. Interior line curved and dentate. In the distal area dark brown not quite to the distal margin. 
Costal margin, apex and beginning of the distal margin mouse-coloured. Above the inner margin behind the 
interior line as far as the cell a triangular blackish-brown shadow. Exterior line as in nenia. Hindwing also 
mouse-coloured, at the costal margin pink. The exterior notched line only distinct at the anal angle, there 
at the margin a series of black dots. Anal angle itself light. Distal margin fine black with light grey dots. $ 
larger. Forewing mole-coloured, dusted with black, at the inner margin suffused with brick-red. Distal margin 
dark, the most extensively in the centre. At the cross-vein somewhat lighter. Interior line blackish-brown, 
notched, exterior line strongly excurved at the costal margin, notched. Hindwing dark mole-coloured with 
a yellowish-white spot as in nenia. Congo. 
C. cana Aur. (= junodi Obth.) (58 i). <$. Violettish-grey. Median area inside indistinctly defined cana. 
by rusty brown at the costal margin, in the posterior portion and in the indenture of the exterior line at the 
costal margin rusty brown. Exterior line in the ground-colour double, parted by a dark line, anteriorly strongly 
excurved and from there to the apex a brown shadow. Hindwing greyish-brown, at the base feebly pink. At 
the anal angle and at the centre of the anal margin violet spots. A <§ is intensely suffused with brown on both 
wings, in front the exterior line is only shadow-like. $ greyish-brown. On the forewing before the centre of 
the inner margin and at the inner angle grey, on the middle often brown. Exterior line often marked. Hindwing 
lighter, with the spots as in the <$. 50—60 mm. Delagoa Bay, East Africa. 
C. agathylla Westw., described from a very much damaged specimen, only exhibits the very much agathglla 
produced apex of the forewing and may be identical with one of the larger species. 90 mm. Congo.
