58 SOUTH-AFRICAN BUTTERFLIES. 



black line or streak at extremity of discoidal cell ; on hind-margin a 

 row of six sub-rhomboidal black SjDots, generally united by a very 

 faint regularly festooned blackish streak, which touches their inner 

 extremity ; base slightly glossed with a pearly lustre. Under side. 

 — Fore-iuing : similar in marking; marginal band much larger than 

 on upper side, of a j;«/e greyish-yellow, only separated by the black- 

 clouded nervules. Hincl-iving : entirely pale greyish-yelloio ; all the ner- 

 vules hroadly defined ivltJi Uach ; festooned submarginal streak much 

 darker and well developed, and presenting an additional separate por- 

 tion (beyond middle, but before the main portion) between costa and 

 second subcostal nervule ; spots on hind-margin much thinner than 

 on upj)er side, sublinear ; costa at base edged with bright-yellow ; a 

 bifid black longitudinal streak in discoidal cell, and a simple similar 

 streak between median and submedian ner\T.ires, becoming bright- 

 yellow near base ; a short transverse diffused black mark from extremity 

 of discoidal cell to near middle of submedian nervure, and a similar 

 shorter mark between median and submedian nervures before middle. 



$ All Hack marhings hroadcr than in $. Hind-iving : usually 

 creamy ochre-yellow. Fore-icing : white spots in hind-marginal border 

 always smaller and diffused, sometimes tinged with yellowish, occa- 

 sionally almost obsolete ; costal transverse bar very variable in breadth ; 

 when broadest, not, or very slightly, constricted in the midde. Hind- 

 wing : submarginal festooned streak usually complete and well-marked, 

 as on under side, but variable in development ; hind-marginal spots 

 sometimes so large as almost to touch each other. Under side. — 

 Hind- wing and apical hind-marginal border of fore- wing usually of a 

 clearer yellow than in $, inclining to lemon-yellow. Fore-tving : a 

 rather narrow basal suffusion of orange-yellow. Hind-iving : a short 

 faint edging of orange-yellow on costa a little before apex. 



I have captured three unusually small individuals of this species, 

 viz., a ^ (exp. i in. 9 lin.) and a ^ (exp. only i in. 5! lin.) at 

 Knysna, and another $ (exp. i in. 8 lin.) at Port Elizabeth, Cape 

 Colony. 



The $, as a rule, has the upper side of hind-wings ochre-yellow, 

 and that of the fore-wings sometimes has a very faint tinge of lemon- 

 yellow. The two ^ s in my collection, which resemble the ^ in having 

 the upper side of the hind-wings white, I took at Knysna. 



Specimens of both sexes from the Eastern districts of the Cape 

 Colony, Kaffraria, and Natal are usually a little larger than the typical 

 form from Knysna district, and they almost always have the yellow of 

 the under side clearer and more decided, with an inclination to the 

 tint of sulphur. A ^ taken by Colonel Bowker at Malvern, near 

 D'Urban, Natal, in August 1885, has the under-side yellowish dull 

 and pale, as in the type form, but on the upper side the white hind- 

 wings have a moderately wide border of pale sulphur-yellow all along 

 the hind-margin. Another $ (without label of locality, but taken, I
