Hah. — Java, Singapore {$ , $), Sumatra, Borneo, Celebes {$), 

 Philippine Islands {$) (Coll. Wall.). 



Male. — Above, creamy white with a faint greenish tinge; upper 

 wings with the costal and outer margins narrowly black-bordered, 

 and the apex somewhat dusky. Beneath, bright ochre-yellow ; 

 all but the apex and basal part of the uppers much paler or 

 whitish, costal and outer margins finely black-edged. Head and 

 neck olivaceous, thorax and abdomen ashy. The specimens from 

 Celebes are paler and have a much narrower dark border. Those 

 from the Philippines have a rather broader border, and a narrow 

 one on the hind wings. 



Expanse of wings 2| inches. 



Female. — Above, sulphur-yellow ; upper wings with the basal 

 third dusky; a black border from near the base of the uppers to 

 the anal angle of the lower wings broader on the uppers and 

 enlarged at the apex, its outline toothed within near the outer 

 angle of the lowers. Beneath, upper wings with a black-curved 

 band from the middle of the costa to the outer angle, the disc 

 sulphur-yellow, the base deep yellow, the apex light violet-ash 

 with a yellow margin ; lower wings pale ochre-yellow, with a 

 faint violet tinge, with a narrow border of rich yellow from the 

 base to the anal angle. 



Expanse of wings 2f inches. 



A specimen from Singapore and one from Java exactly agree 

 with this description. It also exactly agrees with Vollenhoven's 

 figure and description of sulphurea {T. panda, 9). except in 

 possessing the narrow border of bright yellow beneath. Some 

 Singapore specimens are very pale yellow above, and have the 

 lower wings tinged with ochre-yellow beneath. Dr. Felder's 

 description of the male refers to a Malacca specimen ; the 

 Philippine form having a distinct border to the hind wings, and a 

 dusky patch near the outer angle of the fore wings beneath, is 

 almost sufficiently distinct, in such a group as this, to deserve a 

 separate name.
