1921] MouLTON : Malaysian Butterflies. 185 



The intensive blue reflection in the male in menetriesi 

 is not very noticeable in ten males from the Malay Penin- 

 sula compared with the Siamese subsijecies limborgi 

 Moore, of which there is one very beautiful male from 

 Hat Sanuk or Tasan, S.W. Siam, in the F.M.S. Museums 

 One male from Selangor however approaches limborgi in 

 the more pronounced and better defined white spots of the 

 hind wing above. 



One other species of this subgenus occurs in the 

 Malaysian subregion, viz : — 



39. Euploea haworthi Luc. haworthi Luc. 



Euploea haworthi haworthi Fruhstorfcr 1910, p. 237. 



Distrih. The typical form occurs on Java and Bali 

 with a subspecies on Sumatra : — 



E. h. haivorthi Luc. Java and Bali. 



E. h. inconspicim Moore Sumatra. 



Subgenus Stictoploea, Butl. 



The two sexual brands in the fore wing of the male 

 and the very deep blue reflection on the fore wings of both 

 sexes at once make the only Malay Peninsula species of 

 this subgenus easily recognizable.

Distrih. This subspecies extends north to Siam, 

 Burma and Cochin-China.^ 



Fruhstorfer {I.e.) keeps as separate species : harrisi 

 for the continent, lacordairei for the Indo-Malayan islands 

 and dufresne for the Philippine Islands. It seems to me 

 preferable to treat them as one species, subspecrfically 

 distinct from one another in their own particular regions. 

 I therefore adopt the oldest name dufresne Godt. for the 

 species instead of harrisi. Fruhstorfer evidently inclines 

 to the same view, as he writes : " Whether all the three 

 species now regarded as separate belong to one species is 

 a question which can only be solved by further anatomical 

 research." hi discussing Austro-Malayan forms' hv writes: 

 " But in spite of all the statements to the contrary, there is 



' One example in the F.M.S. Mus. from Pulau Condore is 

 referable to Moore's melanotic aberration croiuleyi originally 

 described from Tenasserim.
