152 SOUTH- AFRICAN BUTTERFLIES. 



rather diffused, and near base extending a little into discoidal cell, its 

 extremity broad and more or less truncate. Hlnd-iving : base rather 

 widely blackish except on inner-marginal border ; a wide costal black 

 stripe, a small downward projection of its extremity marking commence- 

 ment of discal ray ; this ray linear or obsolete as far as radial nervule, 

 but inferiorly broad, black, diffused internally, but externally more or 

 less completely confluent with a wide hind-marginal black border radi- 

 ating deeply on nervules, so as to leave nothing more than four nar- 

 row white rays or white lines on inter-nervular folds. Uinder side. — 

 Forc-iving : base sometimes slightly tinged with sulphur-yellow ; apical 

 orange well developed, rarely with the faintest trace of inner dark spot, 

 externally bordered (very broadly apically) with pale sulphur-j^ellowish ; 

 disco-cellular terminal dot always distinct ; inner-marginal stripe grey, 

 with extremity blackish. Hind-wing : white, yellowish-white, or dull- 

 creamy ; costa conspicuously orange-edged from base to beyond middle ; 

 a disco-cellular terminal black dot, in contact anteriorly with a much 

 larger pointed orange spot ; a very faint shade indicating position of 

 costal stripe of upper side ; discal ray and hind-marginal border also 

 usually scarcely indicated, but the former sometimes better expressed 

 (especially at its costal origin), and in a few specimens diffusedly marked 

 in brownish-red or pale-ferruginous. In both wings a terminal nervular 

 series of minute but veiy distinct black dots. 



^ IVIiite, or ycllowish-ivhitc ; orange of cqnccd patch exceedingly vari- 

 able in extent, — in some examples almost as in $, except for a very faint 

 and narroio traversing series of dushy nervular marks, — more often 

 reduced to a narrow curved hand only partly invading a broad inner 

 hlackish border, — still more diminished to a centred series of three to five 

 separate very dull ixde-orange, yellowish, or even whitish, spots in a black 

 apical patch, — rarely wholly obsolete, leaving thepcdch dusky -blackish only. 

 Fore-wing : disco-cellular terminal spot much larger than in ^, and 

 almost always touching inner-marginal black stripe, which is broadei', 

 and almost fills discoidal cell, — its superior terminal portion projecting 

 so as to join inner border of apical patch on second median nervule. 

 Hind-wing : basal blackish extending thinly beyond cell as far as lower 

 part of discal ray ; costal stripe as ii\ $ ; a small, but usually quite 

 distinct, terminal disco-cellular black dot ; discal ray complete from 

 its costal origin, and usually more distinguishable from hind-marginal 

 border than in ^, the white inter-nervular rays being broader, and 

 sometimes themselves confluent. Under side. — Much duller and deeper- 

 tinted them in ^ ; hind-unng and apex of fore-wing varying from dull 

 greyish-creamy or yellowish-creamy to reddish-creamy , sparsely irrorated 

 with dark-grey ; markings similar to those of $, but stronger. Fore- 

 wing : apical orange very variable, usually much narrower and fainter 

 than in ^, never wholly absent ; a dusky streak traversing it near its 

 inner border.
