P. Amasene and in the said female variety of P. Paulina is intermediate 

 between the more advanced stage in the colour evolution, reached by the q" of 

 P. Paulina, which have already lost the black entirely, and an earlier stage in 

 which that black must have had a still much larger extension. So is, for 

 instance, the black on the upper-side of the fore-wings of the European Pieris 

 Brassicae L. nothing but a remnant of the black, which, in a less advanced 

 stage of colour- evolution, had there a much larger extension ; this is clearly 

 indicated by the races of this butterfly, which still exist in Japan and in the 

 Canaries and which, iieing still less changed, are intermediate between these two 

 stages and, therefore, have still much more black than the European race, though 

 already much less than must have been the case in a still less advanced stage. 

 Though at present the general colour is nearly always white alread)', 

 Fruhstorfer has still caught some yellow $ in E. J., and also some, whose 

 upper-side is already white, but whose under-side is still yellow. According 

 to this entomologist yellow 9 are common in Lombock. De Niceville mentions 

 white as well as yellow 9 of Sumatra. Consequently in this respect the same 

 process of colour-evolution can be observed, which draws still much more the 

 attention in the following species P. Panda Godt. According to Neville 

 Manders {Trans. Ent. Soc. of London, IQ04) this species belongs to the migrating 

 butterflies in Ceylon in the mountainous regions. This is, as far as I know, 

 not the case in Java, where, indeed, the species is not numerous enough to 

 attract attention to the matter.
