1. DANAIS {Bahora) KHEILI, Staudinger, PI. R, Figs. 1, ^ ; 2, 9 , 



JD. Jiheili, Staudinger, Ex. Schmett., p. 48 (1885). 



Habitat : Nias Island. 



Expanse : ^, 2'8 ; $ , 2'9 and 3*0 inches. 



Description : Male and female. UppePvSIDe, both wings fuscous, 

 with all the hyaline markings gamboge-yellow, the marginal series of 

 dots paler. Forewing with the two discal streaks divided by the upper 

 discoidal nervule long and narrow, the lower one-third longer than 

 the upper. Undeeside, both icings a little paler than above, the outer 

 discal spots outwardly becoming whitish, the submarginal and mar- 

 ginal series of spots pure white. 



Differs from both sexes of D. aspasia, Fabricius {=D, crocea^ 

 Butler), and D. philomela^ Zinken-Sommer (which, in the female, are 

 absolutely indistinguishable except that the two streaks divided by 

 the upper discoidal nervule are shorter and broader, and the mar- 

 ginal dots do not reach the apex of the wing in the latter, though the 

 males are easily separable owing to the greater extent of the yellow 

 coloration on the upperside in the latter, which invades the discoidal cell 

 and inner discal spots), in having all the markings of the upperside yel- 

 low, in those species in the female all the hyaline markings of the 

 forewing are bluish-white except the basal portion of the submediau 

 streak, and the hindwing in those species has the markings on the 

 basal half of the wing alone yellow, those on the outer half being- 

 bluish- white. 



I cannot admit that D. aspasia^ Fabricius, and I), crocea^ .Butler, are 

 distinct, though Mr. Moore in his monograph of the subfamily in the
