that are black on the upperside a much darker silvery blue. 

 Antennae, head, thorax and abdomen dusky brownish black ; 

 beneath : the palpi, thorax and abdomen very pale blue. 

 $ . Upperside : ground-colour of a paler blue than in the J and 

 much overlaid with dusky black. Fore wing : base broadly and 

 densely irrorated with black scales, two elongate black streaks in 

 cell that do not reach its apex and all the veins broadly bordered 

 with black ; this colour coalesces on the outer half of the wing 

 and leaves only broad streaks at bases of interspaces 1 a to 6, with 

 beyond them a transverse series of spots of the ground-colour 

 visible. Hind wing : dorsal margin below vein 1 and costa above 

 cell white, all the veins except the upper discocellular more or 

 less broadly lined with black, which colour coalesces outwardly 

 and forms a broad border to the termen ; two or three of the 

 streaks of the ground-colour between the veins are succeeded by 

 subterminal spots of the same tint. Underside : silvery white, 

 the veins more prominently picked out with black than in the c? 

 Antennae, head, thorax and abdomen as in the tf but darker. 



Exp. c? 2 78-90 mm. (3-08-3-54"). 



Hab. Sikhim, from 1000 to 5000 ft. ; Bhutan ; Assam ; the 

 Khasia and Naga Hills; the hills of Burma and Tenasserim. 



The Tenasserim avatar is a smaller and somewhat darker 

 variety, confined, as far as known, to the Dawnat range and other 

 southern ranges of hills in Tenasserim. It is barely separable from 

 typical avatar, but all the specimens I have seen have in the J 

 a slightly wider black margin on the upperside of the hiud wing, 

 and the $ is on the whole slightly darker. The late Mr. de 

 Niceville separated it in his MS. under the name " paravatar" 



Exp. 3 2 67-81 mm. (2-63-3-18"). 



Hab. Hills of Middle and Southern Tenasserim. 



The type form, P. Valeria, Cramer, so far as I know, is confined 

 to Java. It has the ground-colour of the wings on the upperside 

 of even a paler blue than in P. avatar, almost white, but with broad 

 black terminal margins as in its two Indian representatives, cey- 

 lanica and pinyasa, and like them bears no transverse subterminal 

 series of spots on the fore wing.

 deeper tint than in P. avatar, Moore ; all the veins defined with 

 black. Eore wing : costa broadly, apex and terminal margin 

 very broadly black, this black on the termen narrowed towards 

 the tornus, and traversed by a transverse subterminal series of
