NYMPHALIN^. 251 



grey rather narrow, bounded inwardly by a large conspicuous but ill- 

 defined subquadrate fuscous patch ; the subapical spots of discal row in 

 the middle of very indistinct brownish-ochreous rings. Sind-wiug : 

 before middle an irregular, broken, transverse ochre-yellow streak ; 

 about middle a similar but more continuous streak ; both these streaks 

 include an outer thin line of brown, and the space between them is 

 sometimes duller grey than the rest of the wing ; a short streak of the 

 same colouring at extremity of discoidal cell ; seven spots of discal row 

 well marked, in the middle of seven contiguous ochre-yellow rings ; a 

 smaller, additional, similar, rather indistinct spot before the seventh 

 on inner-margin. 



$ Ground-colour ycUoiver, clearer ; apical fuscous of fore-wing much 

 broader and darker, and enclosing two conspicuous, j^arcdlel, ohlique, 

 macular rays of a paler ochre-yellow than the ground-colour. Hind- 

 wing : discal spots rather larger than in ^. Under side. — Hind-iving 

 and ajpex of fore-wing paler than in $, all the markings letter defined. 

 Fore-wing : ground-colour deeper ; subapical fuscous patch enlarged to 

 imperfectly enclose an interrupted oblique ray corresponding to that on 

 upper side. 



Compared with its very close ally, C. Madagascariensis, Boisd., this 

 butterfly is in both sexes characterised by a more rufous instead of 

 olivaceous upper-side tint of ochreous, and by the much less develop- 

 ment of the apical fuscous in the fore- wings, especially in the ^, where 

 it is little more than a dusky suffusion without defined limits. The 

 under side hoary-grey is inclining to a lilacine tinge, and almost free 

 from the fine fuscous irroration noticeable in Madagascaricnsis, while 

 the rings of the ocellate spots and the basal and median streaks in the 

 hind- wing are ochre-yellow (the latter brown- edged) instead of fuscous. 

 All the three transverse streaks of the hind-wing are also less irregular 

 and dentated. 



This butterfly is not imcommon at D'Urban, in Natal, though apparently 

 much less numerous than its near congener, C. Boisduvali, "VVallengren, witli 

 which I associated it in my lOiopalocera Africce Aitstralis, taking the few 

 true G. Natalensis I had seen as only larger and paler examples of the same 

 species. Both forms have quite the same habits, flitting about trees in wooded 

 spots, and frequently settling on the trunk or branches. The specimens I cap- 

 tured Avere on the wing in February, but Colonel Bowker took a good many in 

 August.
