Below the cell a chocolate-brown spot distally, from which a line extends to j)ostmedian line at inner margin. Reni- 
form stigma with brown surround, expanding below and dark brown posteriorly. Outer line delicate, fuscous, 
outwards to vein 7, then somewhat inwards to submedian fold, bending upwards to lower corner of reniform 
stigma and then again outwards to inner margin. Distally blackish spots from vein 6—3. Submarginal line 
indistinct, jrale, dentate, edged on both sides by fuscous. Hindwings inclijied to fuscous in marginal area. A 
delicate undulate brown line from lower angle of cell to inner margin, cj 30 mm. East Africa. 
2. Antennae of (J ciliate. Central tibiae of y obese, with a cavity, edged by coarse scales. 5'he 3 first spec¬ 
ies white. 
C. diapera Hmps. (30 h). Thorax and forewings white. Antemedian line delicately brown, angulated diapem. 
outwards on median nervure in a right angle and then inwards. Median line indistinct, double, parallel to 
antemedian. Reniform stigma indicated by brown lateral streaks. Postmedian line black, faintly duplicated 
outwardly. Slightly excuived at vein 6 and again more boldly at vein 4, somewhat impressed behind cell, 
further incurved at vein 2. A wide diffuse oblique stripe extends from apex to postmedian line. Hindwings 
yellowish white, browner at margin. 30 mm. Transvaal. Only 2 specimens are known. 
C. setifera Htnps. Antennae of with long hairs on upper side before the centre. Foretibiae with long seiifera. 
hairs, central and hind tibiae with shorter hairs. Hindwings on underside with hairs that are directed down¬ 
wards at lower end of cell, but upwards on submedian fold. Body and wings white, faintly tinged with brown. 
Forewings slightly fuscous in marginal area. Antemedian line consists of black dots forming a line downwards 
from median nervure, angulated outwards on submedian fold. A black dot in centre of cell and a streak at 
disco-cellular. Postmedian line black with a spot on costa, excurved below costa, undulate to vein 5, then 
inwards, angulated outwards below vein 2. Submarginal line whitish, edged by brown on both sides and un¬ 
dulate. Hindwings slightly brownish at margin. A black streak at disco-cellular, with a diffuse line below to 
inner margitr. Postmedian line dark, undulate, sribmarginal line pale. ($ 30 mm. Central Africa. Only this one 
specimen is known. 
C. leucoptera Hmps. (30 g). Thorax and forewings oehreous white, marginal area grey-white. Inner leucoptera 
line heavy, black, obliquely outwards to submedian fold, then vertically. Proximally a grey suffusion. Median 
line indistinct, double, brown, undulate. Reniform stigma blackish and elliptical. Postmedian line black, ex- 
curved below costa and widely in the centre. Behind the cell it is faintly incurved and more boldly again on 
submedian fold with a grey-brown shade distally. Hindwings with dark streaks on vein 1 and 2 in marginal 
area. The $ from East Africa, that we are illustrating, has a darker margin to both wings than Hampson’s 
original illustration, but nevertheless should probably be placed here. 27—30 mm. Algeria, Somaliland, East 
Africa, Aden. 
According to Rothschild in Novit. Zook 27, p. 23, fasciolata Warr., balnearia Dist., and also disjiar 
Pnglr. from the Dead Sea, impar Hrnps. and eremochroa Hmps., both from India, are all forms of one species, 
that occurs in transition forms on the coast of Somaliland. Hampson and we, in this work, have treated them 
as separate species, leucoptera Hmps., which is tlie rarest form, was unfortunately described first. 
C. metaxantha Hmps. (30 h). Forewings oehreous grey admixed with fuscous, basal area blackish. Inner metaxantha. 
line bold, black, excurved and undulate with a parallel fainter line proximally. Median line indistinct, double, 
excurved to median nervure, then vertically, darker posteriorly at costa and inner margin. Reniform fuscous, 
boldly curved. Postmedian line black, undulate, sharply incurved below vein 4, distally narrowly brown. A 
pale grey band vertically to anal angle, darker distally. Hindwings orange-yellow, an outer line indicated on 
inner margin, outer margin narrowly dark. The specimen illustrated {^) differs from the original illustration 
by the much more acute angulations of inner and outer lines on submedian fold. As only this species has orange- 
yellow hindwings, probably a specimen before me from South West Africa, will prove to be the hitherto un¬ 
known $ belonging here, especially as the illustrated also occurs there. On it the angulations of both lines 
are much less acute on the submedian fold, than in the illustration. The grey band, distally of the postmedian 
line is absent. A few further specimens from South West Africa are much less distinctly marked than shown 
in our illustration. 26—30 mm. South West Africa, Damaraland and the Cajie. 
C. minyas Fawc. (20 h). Body oehreous grey. Forewings pale fuscous at base to antemedian line. Lines viinyas. 
black and undulate, approximately vertical. Central area grey to postmedian line with indistinct dark hues. 
Reniform stigma with faint oehreous brown surround. Outer line black, distinct, angulated outwards below 
costa, again on vein 6 and 4 and angulated inwards on vein 3 behind the cell and on submedian fold. Distally 
thereof paler rusty brown with dark spots before the margin. Hindwings pale oehreous brown, somewhat darker 
at margin; double median and submarginal lines at inner margin. 30—34 mm. East Africa. 
C. griseacea Fawc. Very similar to minyas (20 h) and originally described as a form of it. Forewings griseacca. 
greyer distally of antemedian line, with a rusty brown band submarginally, that is most distinct at apex. Hind¬ 
wings paler. According to the author, these two species come between the palaearctic f/ispar Pnglr. jasciolata 
Warr. (Vol. 3, pi. 62 e and 63 a). $ 30 mm. East Africa. Only this one specimen of griseacea is known. 
C. fasciolata Warr. (30 h). Thorax and forewings oehreous reddish. In basal area, the outer median fasciolata, 
area and close behind the postmedian line, the colouration is browner. Antemedian line black, somewhat double,
