Sub-sp. E. halitherses bomeensis, Dist. 



The typical form occurs in India, Assam and Burma, 

 the sub-species bomeensis is confined to Borneo, other 

 sub-species occur in the Malay Peninsula, Sumatra, Java, 

 Nias, Palawan and the Philippines. The different forms 

 of the polymorphic female of this species have been given 

 a great variety of names and the result is that the rela- 

 tionships between the different forms and between 

 topomorphic varieties are much obscured. I believe 

 that three fairly distinct female forms and three only 

 can be recognised, viz. : — 



1 . A form mimicking both sexes of the species of the sub- 

 genus Danisepa, to which the name isa, Moore may be 

 applied ; alcatheoides, de Nias danisepa. Fruhst, pfeif- 

 feroides. Fruhst. etc., are merely more or less well- 

 marked varieties of this form ; in Borneo or elsewhere 

 this form is highly variable and no two specimens exhi- 

 bit identically the same markings. 



2. A form mimicking a Euploea such as Penoa uniformis, 

 to which the name uniformis, Fruhst. may be applied ; 



Jour, Straits Branch
