PARTHENOS. 289 



oblique black line across cell, followed by a white transverse bar, 

 two more or less triangular subh valine white spots and, beyond, a 

 white subcostal similar but elongate spot, all these spots bordered 

 by black on both sides. Following these is an inwardly-oblique 

 discal band of large subhyaline white spots of varying shape, 

 running from the costa, just before the apex, to interspace 1, 

 where it terminates in a bluish diffuse patch ; black postdiscal 

 and terminal macular broad bands ; the narrow line of green 

 ground-colour between the bands sinuous. Hind wing : a basal and 

 a subbasal transverse black streak, ending outwardly in white spots, 

 a transverse discal series of black spots decreasing in size anteriorly, 

 succeeded by a postdiscal series of narrow linear paired streaks in 

 the interspaces, each pair more or less confluent in the middle ; a 

 postdiscal curved series of triangular black spots and a terminal 

 broad black band. Underside : fore wing diffusely pale bluish 

 green, the broad discal band and the markings in cell and beyond 

 it towards apex very similar to those on the upperside, the two 

 black streaks from base wanting, the postdiscal and terminal 

 black bands faint and very ill-defined. Hind wing: basal half 

 pale bluish green, apical half white or in some specimens ochra- 

 ceous grey ; the transverse basal and subbasal black streaks absent ; 

 a discal, highly sinuous, somewhat interrupted, transverse black 

 line and the postdiscal, subterminal and terminal black markings as 

 on the upperside, but very faint and ill-defined. Antennae black, 

 head, thorax and abdomen olive-green barred with black ; beneath 

 whitish. 



Exp. <3 2 98-120 mm. (3-87-4-75"). 



Hab. Eastern Bengal : Manipur ; Assam ; Burma, and Tenas- 

 serim. 



Var. apicalis, Moore, is a slight variety, having the apex of the 

 fore wing pale as if rubbed — a variation which becomes constant 

 in the Andaman race. Many specimens from Tenasserim have the 

 base and the space between the black bars and discal line of spots on 

 hind wing blue — a feature which is constant in the Chinese and 

 Malaccan race (sylla, Donovan == Uliacinus, Butler). 



Race roepstorffi, Moore. — Similar both on the upper and under 

 sides to the typical form. Differs in being on the whole smaller 

 and in the entire absence either on the fore or the hind wing of 

 any suffusion of blue on the upperside ; the apex of the fore wing 

 always has a rubbed appearance. 



Exp. <5 2 94-104 mm. (3-7-4-1"). 



Hab. Andamans and Mcobars.
