 primaries. 



Wet phase. Dry phase. 



C. thaurama, Reak. C. Grandidieri, Mab. 



These differ much as C, pomona does from C. crocale. 



CJlorella, Fabr. C. pyrene, Swains. 



C. aleurona, Butl., is a wet intermediate phase, and 

 C. hyhJcea, Boisd., dry intermediate : all four occur together 

 and interbreed at Aden. 



C. pyranthe, Linn. C. thisorella, Boisd. 



Oddly enough, C. cJiryseis^ Drury, which is seen by the 

 under-surface characters to be a dry type, is distinctly larger 

 than C. pyranthe and quite as heavily bordered on the upper 

 surface; the size probably has a local significance (many 

 Chinese forms being large). Other intergrades between the 

 extreme wet and dry phases are G. alcyone^ Cram., G. minna^ 

 Herbst, and G. ilea, Fabr. 



G. evangelina, Butl., is a representative of G. pyranthe^ 

 occurring in Flores, Bali Island, and Sumatra; it is a very 

 round-winged species with a wet character of upper surface 

 but a distinctly dry under surface. 



G. nephte^ Fabr., is a wet pliase with a very dry aspect of 

 upper surface; the dryest phase of it which I know is 

 G. gnoyna, Fabr., but it is not very marked. It seems related 

 to G. lactea from Australia, of which I know only a dry 

 phase. 



C. gorgopJione, Boisd. C. hinda, Butl. 



I have recoo:nized only females of the dry phase, from 

 which I should judge that the males have a much closer 

 resemblance to those of typical G. gorgophone. 



C. scylla, Fabr. C. etesia, Hewits. 



I think this last doubtful ; it is quite possible that it is 

 merely a variation with no seasonal significance.
