EURASIAN & AUSTRALIAN NEPTINI 125 



I prefer to divide the complex into five species since : — 



a. this emphasises the distinctive characters, which are more comprehensive 

 than the few selected for my key, of the assemblages of subspecies found in each of 

 the five main zoogeographic divisions of the Papuan subregion. 



b. I think that differentiation has proceeded so far that interbreeding between 

 any of these assemblages would be unlikely in nature. 



c. it involves minimum interference to the arrangement made by previous 

 authors, notably by Fruhstorfer (1913, in Seitz).

Phaedyma heliopolis C. & R. Felder 



Dimorphic throughout the North Moluccas. The typical dimorph f. heliopolis, 

 with narrow white markings and very dark under surface ground colour, occurs 

 unchanged throughout the group (except that there are no examples in BMNH 

 from Morotai). The other dimorph, with wider white markings and paler under 

 surface ground colour, varies geographically. In Obi f. graciella has very wide 

 white markings and the under surface ground colour is markedly paler. In Ternate 

 f. ternatensis is intermediate in all respects. In Bat j an, Halmahera and Morotai
