250 SOUTH-AFEICAN BUTTERFLIES. 



genus comprises two sections very distinct in ajipearance. The first of 

 these, represented by the type C. Madarjascaricnsis, Boisd., consists of 

 middle-sized or rather small butterflies, with apically produced fore- 

 wings, and of dull yellow-ochreous and brown 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 shining-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 — Natalcnsis, Boiscluvali, and Morantii — are closely related to 

 the Malagasy type-species ; but the very rare C. Bosa, Hewits,, dis- 

 covered at Delagoa Bay, is a very handsome member of the second 

 section above described. 



C. Natalcnsis and C. L'oisduvali 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.

^ Bull i/dlounsh-ochrcous, clouded with fitscous-hroumisJi in ajncal 

 area of fore-vnng ; a common discal row of small black spots and a 

 common row of thin black lunules close to hind-margins, which are 

 narrowly clouded with brownish. Forc-u-ing : 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-ivmg 

 and a2Jcx of fore-wing lioary-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
