NEW ORIENTAL PAPILIONID^. 3 



8. Troides helena neoris, subsp. nov. 



Abdomen much paler above than in hephcestus, being yellowish 

 brown, with the sides and under surface grey. 



3^ . Fore wing with very feeble vestiges of light streaks on the 

 under side ; the distal margin somewhat more incurved than in 

 hephcestus. The black marginal band of the hind wing as broad as 

 in extreme specimens of hephcestus, being much broader than in the 

 Malayan forms of T. helena. 



? . All the veins of the fore wing, inclusive of the submedian, 

 accompanied by very broad greyish white streaks, the streaks situated 

 at the second median vein being remote from the cell ; the apical 

 third of the cell greyish white above, with two blackish streaks, 

 beneath almost pure white. Golden cell-spot of hind wing proxi- 

 mally almost cut off straight ; no yellow discal spot in front of the 

 subcostal vein, the black marginal band broader than in hephcestus, 

 and the fringe-spots larger. Beneath the central area of the hind 

 wing yellowish grey, being more distinctly yellow in the centre. 



Hah. Binongka, Joekan Bessi Islands, south-east of Celebes. 

 One pair, collected by H. Kiihn in December, 1901. 



9. Troides helena mopa, subsp. nov. 



$ . Intermediate between neoris and hephcestus. Abdomen more 

 yellow than in neoris, with small black spots on the under side. 

 Fore wing as in strongly striped females of hepthcestus. The black 

 distal margin broader than in hephcestus ; the central area on the 

 vmder side as pale as in neoris at its anterior basal and posterior sides, 

 the area being the same as in neoris, except that a much larger por- 

 tion is yellow. 



Hah. Buton, south-east of Celebes, December, 1901 (H. 

 Kiihn). Only one specimen. 



10. Troides helena antileuca, subsp. nov. 



The abdomen as black above as in sagittatus, not being so 

 distinctly pale in the centre as in helena from Java. 



<y . Fore wing entirely without light stripes on both sides. Hind 

 wing as in helena ; no golden discal spot before the subcostal vein. 



$ . Fore wing above without grey vein-streaks, the cell also not 

 being edged with grey; beneath the light vein-streaks faintly vestigial. 

 Hind wing with a discal and a submarginal golden spot in front of 

 the first radial vein, both being small ; the golden spot situated behind 

 the cell almost extends to the base ; the black discal spots mode- 

 rately large ; the golden cell-patch cut off in the direction of the 

 first radial. 



Hah. Kangean Islands. One pair (Prillwitz). 



11. Troides helena isara, subsp. nov. 

 $ . Similar to Sumatran specimens of T. helena ; the differences 

 not constant. The grey vein-stripes of the fore wing usually indis- 

 tinct on upper side, always very distinct beneath. The yellow spot
