evolution of Callidryas Pomona F. and often too of Cyllo Leda L. That 

 is why I think it most likel}' that those light specimens still represent an older 

 form, wherein the increase of black pigment, now characteristic of Corva, is 

 not yet effectuated. 



A very superficial contention about a case of mimicry, which is said to 

 take place with this butterfly has rightly been contradicted even by an ardent 

 partisan of the mimicry theor}% Guy A. R. Marshall F. Z. S., page 1 1 8 and 

 following ones of Part I of the Transactions of the Ent. Soc. of London 1 908.

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

 province of Rembang. Also in the province of Japara in the north. 



E. J. Kediri (64) and also in the Tengger mountains at Pouspa (630), 

 Malang (445) and Lawang (500) (Fruhstorfer). 



The caterpillar, at Batavia as well as at Kediri, on the same kind of Cap- 

 PARis, on which feeds also that of P. Java Sparrm. L. Moore mentions the 

 same food of Ceylon and De Niceville of India. It has the common form 

 of PiERis ; the colour is green, the head concolorous with the body ; the back, 

 however, is darker than the sides which are somewhat whitish. Each segment 

 shows some transverse, parallel wrinkles. When magnified on the body numerous 

 white dots are seen and on the sides short, white hairs, though, for the rest, 

 the caterpillar is smooth. The pupa also shows the common Pieris form, green 

 with white Hnes on the abdomen ; the head has a light-brown head-process, 

 while on the edge between thorax and abdomen there is a double pointed 

 transverse dorsal ridge of the same brown colour. On the 7''' day the imago 

 emerged from the chrysalis. 



My figures of the larva and the pupa are much more accurate than those given of 

 Java ones by Horsfield (P. Coronis) and of Ceylon ones by Moore (H. Phryne).
