SOUTH-AFRICAN BUTTERFLIES. 
irrorated with blue as far as middle ; in discoidal cell the irrorations 
form three transverse striae, separated from each other by streaks of 
the black ground-colour ; a waved, irregular, at third median nervule 
sometimes interrupted, blue stripe crosses wing beyond middle, from 
costa to inner margin ; beyond it commences a transverse row of six 
spots parallel to hind-margin, the first two spots being conspicuously 
hluish-ivJdte and of small size, the remainder red (the first of which 
is small, the other three large, and excavate internally ^ where each is 
marked by a deep-black spot) ; beyond this row is another of blue sub- 
lunulate spots ; a line of thin blue lunules close to hind-marginal edge ; 
fringe black, white- spotted in indentations. Hind-wing : basal area 
dusted with blue ; no strife in discoidal cell ; beyond middle, the blue 
and red stripes of fore-ioing are continued across this wing to inner 
margin before anal angle, the Uue stripe becoming indistinct in its 
lower portion, the red consisting of seven conspicuous, internally 
black-dotted spots ; row of lunulate spots and of hind-marginal lunules 
as in fore-iving^ but larger ; fringe white-marked in indentations. 
Under side. — Glossy darh greenish-hronze, with transverse blackish strice. 
Fore-iving : five sinuate, black transverse striae in discoidal cell ; a 
dull-blackish, ill-defined fascia just beyond cell, quite across wing ; 
followed by another, sharply-defined outwardly, and marking the inner 
edge of the blue transverse stripe on u^jper side ; an irregular trans- 
verse row of small black rings (the third from costa conspicuously filled 
with white) ; inner margin glossed with purplish ; a dull-reddish stain 
near anal angle ; two rows of indistinct blackish lunules along hind- 
margin. Hind-iving : much varied with indistinct blackish fascia in 
basal half ; a blackish streak, enclosing a greenish line, at extremity of 
discoidal cell ; a much-dentated, irregular, black line continues the well- 
defined one of fore-iuing to inner margin beyond middle ; also a row 
of five or six little black rings, continuous of that of fore-iuing, as far as 
first median nervule ; two rows of blackish lunules along hind-margin, 
less distinct than in fore-wing, but ending in a black mark at anal angle. 
Larva. — " Dark velvety-brown, with transverse rows of light- 
brown tubercles, which are centred with rather long, branched spines. 
Head light reddish-brown, with a black spot on each cheek, and one 
above the mouth, and crowned with two long branched spines." — 
H. C. Harford, MSS. description of Natalian specimen. 
This is the Southern representative of the West- African P. Ames- 
tris (Drury), and is separable from that species by (i) its conspicuous 
basal blue irroration, (2) the constancy and large development of the 
blue discal band, (3) the less irregular black and red discal row of 
spots, (4) the absence of red striae in discoidal cell of fore-wings, and 
(5) the uniform dark bronzy-green tint of the under side, without any 
representation of the red spots of the upper side except near anal 
angle of fore-wing. F. Sesamus is also larger than P. Amestris. It 
varies somewhat in the tint of its blue colouring, some individuals
