SOUTH-AFRICAN BUTTERFLIES. 
genus comprises two sections very distinct in appearance. The first of 
these, represented Ly the type C. Iladagascariensis, Boisd., consists of 
middle-sized or rather small butterflies, with apically produced fore- 
wings, and of dull yellow-ochreous and brow^n tints above, while 
beneath their colouring is pale-grey with darker streaks and ocellated 
spots. The second, of which C. Amulia (Cram.) is typical, are rather 
larger insects, whose fore-wings are not or very little produced, with 
blue or metallic-violet upper side and a rich yellow-ochreous or orange- 
ochreous under side, with shiniug-violaceous or greenish-white streaks 
and ocellated spots. C. Ilihhei, Dewitz, from Angola, is to some 
extent intermediate between the two sections, combining the outline 
and dark colouring of the first group with a purple upper-side gloss. 
The genus is quite tropical, but better developed to the south than 
to the north of the Equator. The three very nearly-allied species found 
in Natal — JVatalensiSy Boischtmli, and Morantii — are closely related to 
the Malagasy type-species ; but the very rare C. Ilosa, Hewits., dis- 
covered at Delagoa Bay, is a very handsome member of the second 
section above described. 
C. Natalcnsis and C. JJoisduvali are confined to wooded spots ; their 
flight is weak and short, and they keep much about a particular tree 
or group of trees in little companies, settling very frequently on the 
trunks and branches. Colonel Bowker has found them come freely to 
sugar," and I have noticed them drinking the moisture exuding from 
wounds in trees.

J Dull ydlowish-ochrcous, clouded with fuscous-lroumish in cqjical 
area of furc-vjing ; a common discal row of small black spots and a 
common row of thin black lunnles close to hind-margins, which are 
narrowly clouded with brownish. Forc-icing : fuscous-brownish ill- 
defined interiorly, commencing at about extremity of cell, and leaving 
a subapical rather indistinct oblique macular ray of the ground-colour ; 
in discal row of spots a wide interval, two being wanting between third 
and first median nervules. Hind-iving : seven spots in discal row, 
more conspicuous than in fore-wing, ringed rather widely with yellow- 
ish-ochreous slightly paler than the ground-colour. Cilia fuscous- 
brownish, with whitish inter-nervular marks. Under side.- — Hind-iviiig 
and a]jcx of fore-wing hoary-grey ; a submarginal common fuscous 
streak broken into inter-nervular spots in fore-wing, but more linear 
and continuous in hind- wing. Fore-iving : yellowish-ochreous ground- 
colour much paler and clearer, especially near inner margin; apical
