PAPIHO. 87 



terminal series of claret-red lunules in interspaces 2, 3, 4 and 5, 

 followed by a series of ochraceous-red obscure terminal narrow 

 lunules in the interspaces, the cilia on the outer margin of each 

 conspicuously white. Underside : fore wing as in paris but an 

 erect ochraceous-white postdiscal band as on the upperside 

 limits ; the series of internervular pale streaks on the outer 

 half of the wing. Hind wing : a well-defined discal ochraceous- 

 white band formed of a series of somewhat lunular marks in the 

 interspaces, these increase in width anteriorly ; a subterminal 

 series of claret-red hmules traversed by violet scaling on the inner 

 side as in paris, but much broader and more prominent ; finally a 

 terminal series of ochraceous-yellow lunular marks in the inter- 

 spaces ; the cilia that border each lunule white. Antenna?, head, 

 thorax and abdomen as in P. paris. 



Exp. tf $ 108-121 mm. (4-24-4-75"). 



Hdb. Recorded from Sikhim and Bhutan only. 



In Sikhim. it is recorded by Mr. Elwes as common " in some 

 seasons at certain places, and found from 3000 to 9000 feet 

 elevation." I procured several specimens at Eungarun, near 

 Darjiling, in May. It was difficult to catch, and only one or two 

 of the specimens were. in good condition.

3. Upperside brownish black, somewhat paler on the fore 

 than on the hind wing. Fore wing irrorated with brilliant 

 golden-green scales that on the posterior halt' of the wing form a 

 broad, not well-defined subterminal band ; the veins and elongate 

 streaks between them on the outer half of the wing velvety 

 black. Hind wing : posterior three-fourths irrorated with 

 brilliant golden-green scales as on the fore wing but towards the 

 base anteriorly these turn to blue ; a conspicuous brilliant blue 

 patch somewhat irregular in shape occupies the apex of the cell 

 and the bases of interspaces 5 and 6, prolonged as a broad streak 

 in the latter interspace up to the terminal margin ; below this a 

 more or less triangular patch on the disc and above it the whole 

 of the costal margin broadly are devoid of the irroration of green 

 scales ; a subtermiual generally incomplete series of large claret-red 

 lunules terminates at the tornal angle in a large conspicuous black- 

 centred red ocellus ; "the latter is encircled above and anteriorly by a 

 narrow band formed by a conflux of the green irrorated scales ; 

 the lunules are bordered outwardly by spots of the ground-colour 

 that are devoid of the green scales ; finally both the lunules and 

 the tornal ocellus are tinged more or less with bluish-purple on 

 their inner margins. Underside dull black, with a somewhat 

 sparse irroration of yellowish-white scales confined on the fore 

 wing to the base and apex, and on the hind wing to the posterior
