 A male from Borneo in the Hewitson collection agrees 

 with Semper's male of P. asterope. 



10. Ta cliy ris pal aw a n ica . 

 Appias nero, var. palawanica, Standinger, 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 millim. 



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 Avith 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- 

 boanga (T. domitia ? ), but more nearly resembles T. Jigulina 

 {T. ne?-o } var., $ ) ; its small size and invariably paler 

 colour readily mark it as a different species.
