240 SOUTH-AFRICAN LUTTEEFLIES. 



is described as less reduced than it appears to be in M. Oberthiir's 

 specimens. 



An aberrant ^, taken by Mrs. F. W. Barber near Grahamstown, 

 shows just the opposite tendency, the stripe in the fore-wing being 

 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, tliin, 

 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. Demoleus, but those on back of anal 

 segment pale-yellow, longer, farther apart, and with a straight creamy- 

 Vvhite connecting streak between their bases. Head and thoracic legs 

 pale bluish-green ; pro-legs very pale-greyish with a greenish tinge. 



Described from larvae found on the Orange at Highlands, near 

 Grahamstown. Mrs. Barber informed me that the native food-trees 

 in that locality were Vejjris laiiccolata and Calodendron capense. The 

 dorsal green (excepting the ovate patch of a blue tint) assimilates very 

 closely to that of the 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 Vepris 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
