58 SOUTH-AFEICAN BUTTERFLIES. 
black line or streak at extremity of discoidal cell ; on kind-margin a ! 
row of six sub-rkomboidal black spots, generally united by a very | 
faint regularly festooned blackish streak, which touches their inner 
extremity ; base slightly glossed with a pearly lustre. Under side. 
— For e- wing : similar in marking; marginal band much larger than 
on upper side, of a pale greyish-yellow, only separated by the black- 
clouded nervules. Hind-iuing: entirely pale greyish-yellow ; all the ner- 
vules broadly defined ivith Hack ; 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 upper 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 nervures, 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 black markings broader than in Hind-iving : usually 
creamy ochre-yelloiu. Fore-iving : 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-wing : a 
rather narrow basal suffusion of orange-yellow. Hind-wing : 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, 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
