TRANSFORMATIONS OF SOME SOUTH-AFRICAN LEPIDOPTERA, 297 
Family PAPILIONID/. 
Subfamily P1mR1N # (Bates). 
12. Preris severtva (Cramer). (Plate XLVI. fig. 18, larva; figs. 19, 20, pupa.) 
Larva. Dark greenon back, covered all over with very fine whitish hairs. ‘Two 
lighter subdorsal lines, and below them a row of yellow spots, one on each segment, 
placed in a darker green line. A light yellow lateral line along spiracles above a light 
green line just above thoracic legs and claspers, which, with under surface, are white. 
Head dark brown with minute white spots; Ist segment light yellow anteriorly. 
Feeds on Capparis corymbifera. 
Pupa. Bluish green with two yellow spots on each segment subdorsally, and four on 
each side of thorax. A fine black line along dorsal side of thorax, and two small white 
tubercles with black bases at angle of wing-covers. 
Imago common in Durban and Maritzburg. 
This larva is described in ‘South African Butterflies’ as “Dull reddish sandy on 
back, with a median longitudinal streak of violaceous grey.” It may be dimorphic ; 
but I have never met with a specimen of this colour (‘S. African Butterflies,’ vol. iii. 
p. 69)1. 
13. Pieris HELLICA (Linnzus). (Plate XLVI. fig. 21, larva; fig. 22, pupa.) 
Larva. Yellow above, bluish green underneath ; a light blue dorsal stripe, and on 
each side of it a broader greenish stripe, and below these a pale yellow spiracular 
stripe; body covered by minute black papillae and some sparse short hairs; head 
bluish, covered with black dots. 
Feeds on a common weed in the grass of the veldt, of which I did not get the name. 
Pupa. Yellow above and green underneath, covered with minute black spots. 
Pupal stage lasted only 7 days in February. 
Common everywhere in Natal. 
1 “My description (J. c.) of this larva was made from numerous Natalian specimeus sent alive to me by 
Colonel Bowker. I observed, on the page quoted, that in its earlier stages the larva is dorsally much tinged 
with greenish, and it is of interest to find that the green tint commonly persists till the full-grown stage.”-—
