Philippines. Twentj-seven examples. B. M. 

 A male from Borneo in the Hewitson collection agrees 

 with Seraper's male of P. asterope. 



10. Tacliyris yalawanica. 

 Appias nero, var. palawanica, Staudinger, Lep. v. Palawan, p. 22 (1889). 



The male varying above from brick-red to bright orange, 

 the veins of primaries, and sometimes the veins on apical 

 area of secondaries, dusky ; the apex and outer margin of 

 primaries sometimes with a soft graded brownish border : 

 under surface much more ochraceous, without markings, the 

 centre of primaries more orange than the remainder of the 

 under" surface. 



Expanse of wings 72-77 millira. 



The female varies above from bright orange, through 

 mixed ochreous and tawny, to pure white with dusky basal 

 area and spotted black-brown outer border (as in T. nero and 

 allies) ; below also the wings vary from bright ochreous to 

 ochreous and white commingled or to tawny and ochreous 

 primaries with white subapical streak and pearl-white second- 

 aries clouded with sandy greyish ; the ordinary markings 

 (corresponding with those of the upper surface) more or less 

 defined. 



Expanse of wings 59-66 millim. 



Palawan and Labuan. Ten examples, B. M. 



I cannot regard this as a variation of any known species ; 

 the primaries of the male are more acute than in T. domitia 

 and the under surface unmarked, whilst the female is ex- 

 tremely variable, but has not at all the character of T. zam- 

 hoanga {T. domitia ? ), but more nearly resembles T.figulina 

 [T. nero, var., ? ) ; its small size and invariably paler 

 colour readily mark it as a different species. 



11. Tachyris flavius.
