This is the commonest form of the female both in the Malay Peninsula 

 and China.

This form only differs from male polytes in being larger, and in having tlie 

 band on secondaries formed of smaller spots. The female of this form agrees 

 very well with the same sex oi polytes as figured by Cramer (/. c). 



M. Oberthiir (/. c.) refers to a variety of this species from Chapa and 

 describes it as follows : — 



Var. thibetanus. " Les taches blanc jauniitre du disque des ailes infericures sont extreme- 

 meat retreeies et partiellement obliterees ; dc plus, on voit le long du bord exterieur des ailes 

 inferieures une rangee intranervurale de croissants fauves, qui se termine par une grosse 

 tache anale de meme nuance ; j"ai designe cette variete, dont le facies est tout a fait different 

 du type, sous le nom de thibetanus." 



Distant, in his ' Rhopalocera Malayana,' gives two figures of the varietal 

 form A of the female ; I have examples of both sexes from China whicli 

 agree with his figure 9. Some male specimens from Omei-shan are very 

 interesting, because they have red submarginal lunules on the secondaries, 

 characters which are generally found only in the female of this species. I 

 have a female example from Foochau which is an exact counterpart of these 

 males, and a similar specimen of the female is figured in Moore's ' Lepido- 

 ptera of Ceylon,' pi. lix. fig. 1 a, under the name Laertias romulus. 



In Southern China 1 captured typical males, and also females exactly 

 corresponding with them in colour and marking. In Northern and Western 

 China the var. borealis appears to be the dominant form, but is subject to
