TEANSFOEMATIONS OF SOME SOUTH-AFRICAN LEPIDOPTERA. 297 



Family PAPILIONID.E. 



Subfamily Pierinjd (Bates). 



12. Pieris severwa (Cramer). (Plate XLVI. fig. 18, larva; figs. 19, 20, pupa.) 



Larva. Dark green on 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 ; 1st segment light jellow anteriorly. 



Feeds on Capparis corymhifera. 



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) i. 



13. Pieris hellica (Linnaeus). (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 (I. c.) of this larva was made from numerous JN'atalian sjwcimens 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." — 

 E. Trimen.
