^ Didl-brotvn vjith a tinge of ydlow-ochrcous. Forc-u-ing : unicolor- 

 ous, with only the faint indications of a transverse row of darker spots 

 near hind-margin. Hind-iving : an ochreous tint prevails towards 

 hiud-margin which has an edging of thin lunules darker than ground- 

 colour ; beyond middle, parallel to hind-margin, a row of five small, 

 rounded, blackish spots between nervules. U^'DER side. — Falcr. 

 Fore-wing : duU-ochreous, somewhat glistening ; on costa, a little be- 

 fore middle, an obliquely transverse dark streak, inclining outwards as 

 far as third median nervule ; immediately beyond streak a dusky, ill- 

 defined, darker space ; apical portion pcdc ycUowish-grcyish, with four 

 elongate black spots near the inner edge of the greyish colouring ; a 

 row of seven dusky-blackish short streaks parallel to hind-margin, 

 not reaching to anal angle. Hind-iving: i^cde yellowish-grey ; before 

 middle a broad, irregularly-shaped, violet-grey fascia with brown 

 edges ; beyond middle a row of seven contiguous ocellated spots, 

 violet-grey, black-centred, in golden-brown rings ; on inner margin is 

 an indistinct, smaller, eighth ocellated spot, ivithout a black centre, a 

 little hefore the row of spots ; beyond these a thin dark streak, parallel 

 to hind-margin, composed of united lunules. 



$ Fcder, strongly suffused with yellow-ochreous. Fore-wing : shaded 

 with blackish in apical portion, from extremity of discoidal cell, with 

 an oUiqiie, chdl, yellow-ochreous stripe^ interrupted on third median 

 nervule, from costa about middle to second median nervule, not far 

 from hind-margin; nearer apex is a much shorter, narrower, paler, 

 and less distinct stripe, parallel to the larger one. Rind-iving : yel- 

 low-ochreous tint pervades the whole surface, but is strongest near 

 hind-margin, where the row of black spots is conspicuous, and the 

 brown along hind-margin forms a distinct border to the wing. Under 

 SIDE. — Fore-u'ing : warm y elloiu- ochreous ; the dusky oblique markings 

 from costa in this sex assume the form of two conspicuous blackish 

 stripes ; colouring at apex mueh imler than in ^, yelhwish-ichite, 

 varied with pale-brownish, the black spots very conspicuous. Hind- 

 iving : ground-colour yclloivish-whiie ; fascia before middle much paler 

 than in ^, its brown edges conspicuous ; row of contiguous ocellated 

 spots much paler, their black centres very conspicuous. 



The constantly smaller size and much darker colouring distinguish 

 this form from C. Natcdcnsis, Boisd. In the ^ these characters are 

 very marked, but some of the larger $ examples exhibit a yellower 

 tint than the ordinary ones possess. The under-side markings are 

 all more strongly defined and darker than in C. Natalensis.
