This butterfly, whose eyes during life are pale grey, is, I think, the same 

 as the Appias Taprobana Moore of Ceylon. In this species also the process 

 of the colour-evolution reveals itself as colour-dimorphism, but not, as in the 

 former one, also in the same country. The $ have become white all over 

 at the same time showing a strong increase of the black ; but the 6 have become 

 white in some regions only, but have remained partly yellow elsewhere. In 

 Java all the 6 are white already, but there are also such, whose white shows 

 still a strong yellow hue, certainly because a certain number of scales have 

 preserved the yellow pigment. For little by litde, and very irregularly, does 

 every evolutional change advance. 



W. J. Common in the forest of Pademangan in the lowest part of the 

 surroundings of Batavia, but rare in the somewhat higher regions there (3 — 14). 

 Further at Depok (95), Buitenzorg (265), in the localities adjacent to Pelabouan 

 Ratou or Wijnkoopsbay (+ 1 50) on the south-coast, and from mount Tjerimai 

 in the province of Tjirebon. 



C. J. Touban (2) on the north-coast, Bojonegoro (258) and from the province 

 of Madioun (500); Semarang (4). 



E. J. Malang (445), Kediri (64), in the Wilis mountains, and atjember(98) 

 in the province of Besouki. 



At Buitenzorg the caterpillar feeds on kapok oulan (Crataeva Magna d. c.) ; 

 in Ceylon, according to Moore, it feeds on Crataeva Religiosa Forst. ; in 

 the Botanic Gardens at Buitenzorg I found it also on Roydsia Inaveolens 

 Rub. It is of the Pieris type, head and back are greyish-green, with a gold- 

 coloured dorsal stripe and sprinkled over with small black dots which, when 

 magnified, proved to be sharp spines. The under-side and the sides are pale 

 green, while an indistinct white line forms the edge between these two. The 

 pupa is closely related to that of P. Nerissa F. On the thorax there is a 

 transverse ridge which ends in a long, laterally flattened projection of the 

 head. The middle of the back is broadened, which broader part ends on each 

 side in such another, but shorter projection, beside which there are still two 

 much shorter ones. The common colour is sometimes grey, but generally 

 greyish-green sprinkled over with black dots ; the upper edge of the transverse 

 ridges or enlargements and of the processes, however, is brown, broken here
