SOUTH-AFRICAN BUTTERFLIES. 
is described as less reduced than it appears to be in M. Oberthur's 
specimens. 
An aberrant taken by Mrs. F. W. Barber near Grahamstown 
shows just the opposite tendency, the stripe in the fore- wing beincj 
fully twice as broad as usual. 
Larva. — Deep yellowish-green. Widest portion of back, on third 
thoracic and first abdominal segments, occupied by a subovate patch 
or shield of pale bluish-green, crossed mesially by a thin whitish line, 
closely irrorated generally with white dots, and bearing near its poste- 
rior edge a transverse row of four small pinkish-lilac spots. Ante- 
riorly a greenish-yellow, posteriorly a narrow ochreous-yellow, edging 
borders this patch, the anterior edging being marked with four double 
(concentric) very small, thin, blackish rings, and at each extremity by 
a small black yellow-pupilled ocellus, surrounded by a separate, thin, 
imperfect blackish ring. All the green of the back posterior to the 
patch is mottled irregularly with greenish-yellow. From second to 
last abdominal segment a lower-lateral white stripe ; on each side of 
back more or less distinct traces of a thin yellowish stripe, which in 
some examples is crossed obliquely by a short whitish inferiorly dark- 
bordered streak. Projections on back of first thoracic segment yellow, 
shorter and blunter than in P. DemoUus, but those on back of anal 
segment pale-yellow, longer, farther apart, and with a straight creamy- 
white connectino^ streak between their bases. Head and thoracic le<js 
pale bluish-green ; pro-legs very pale-greyish with a greenish tinge. 
Described from larvae found on the Orange at Highlands, near 
Grahanistown. Mrs. Barber informed me that the native food-trees 
in that locality were Vepris lanccolatct and Caloclendron capense. The 
dorsal green (excepting the ovate patch of a blue tint) assimilates very 
closely to that of tlie upper surface of the leaves of the orange, upon 
which the caterpillar is always found resting; but Mrs. Barber {Trans. 
Ent. Soc. Loncl., 1874, p. 519) has pointed out that when the larva 
feeds on Vejjris it is of a lighter green, so as to resemble in tint the 
leaves of that tree.

Pupa. — Length, i in. 3 lin. Somewhat attenuated anteriorly, 
cephalic processes short and directed laterally outward (not obliquely 
forward, as in Demoleus), so that frontal line of head is widened and but 
slightly concave. Thoracic lateral angles moderately acute ; dorsal pro- 
minence also elevated acutely, but not inclined forward. Sides of abdo- 
men widely flattened, and so extended as to form a very marked angle 
on each side of third abdominal segment ; whence the abdomen narrows 
very rapidly and greatly to the extremity. Infra-pectoral region, where 
wing-covers meet, very strongly convex. A marked constriction dor- 
sally at junction of thorax and abdomen. In its natural position, 
attached vertically or nearly so, head uppermost, the anterior portion
