first median nervule ; apex edged with ferruginous-brown from first 
subcostal nervule on costa to third or second median nervule on hind- 
margin ; a hind-marginal series of minute inter-nervular black dots. 
Hind-wing : slightly paler on inner margin ; a hind-marginal series of 
dots as in fore-wing. Under side. — Hind-iuing and apical area of 
fore-wing deep chrome-yellow with ferruginous marks. Fore-wing : paler 
than on upper side, whitish on inner margin ; close to apex, two or 
three small ferruginous spots with large silvery centres ; a very small 
blackish terminal disco-cellular dot. Hind-wing : sometimes rather 
deeper in tint than apex of fore-wing, thickly or sparsely flecked with 
ferruginous or ferruginous-brown ; a row of rather darker spots along 
costal edge (which is fringed with pinkish and brown hairs), the largest 
and most conspicuous spot elongate, variable in shape, a little beyond 
middle, touching first subcostal nervule ; a curved discal row of six (as 
many as four sometimes obsolete) small ferruginous spots, of which the 
last, between first median nervule and submedian nervure, is much 
the largest and always well marked. Hind-marginal minute spots a 
little larger than on upper side in both wings, ferruginous. 
$ Faler. Fore-iving : orange apical patch duller, sometimes almost 
obsolete, rarely wanting wholly ; apical ferruginous-brown edging wider, 
somewhat diffuse ; a submarginal series of five inter-nervular ferru- 
ginous-brown spots, of which the lowest, between second and first 
median nervules, is indistinct. Under side. — Fore-wing : pale lemon- 
yellow ; beyond discoidal cell orange, deepening into ferruginous-red, 
tinged with pink at apex ; spots at apex larger ; other submarginal 
spots of upper side sometimes faintly indicated. Hind-iuing : more 
thickly flecked than in the spots and atoms pi^iJcer ; the largest spot 
on costa silvery-centred ; spots of discal row enlarged, rounded^ silmry- 
centred, especially a greatly-enlarged spot lying between radial and 
third median nervides ; beyond this conspicuous spot and the smaller 
one just above it, a patch or cloud of ferruginous-red tinged with pink 
extending to hind-marginal edge ; usually a diffused pink stain from 
base between median and submedian nervures to beyond middle. 
In both sexes, but usually more prominently in the the under 
side of the hind-wing also bears an obliquely-transverse ill-defined fer- 
ruginous streak running from the extremity of the discoidal cell to 
submedian nervure before middle. 
There is much variation in size as regards both sexes.^ In colour- 
ing and pattern the $ is much more constant than the ^ ; the upper 
side offering merely some modifications in the tint and development 
of the apical ferruginous-brown or dark-brown edging in the fore- 
wings, which when best expressed radiates slightly on the nervules, 
and the under side exhibiting a deeper or lighter chrome-yellow and 
^ Boisduval {op. cit.) observed that Abyssinian specimens were a third smaller than those 
which he had received from Natal ; but I have received very small examples as well as very 
large ones from the latter country.
