PIERIS. 171 



On the hind wing the subcostal black spot before apex much 

 larger, more prominent. Underside: similar to that of the d 1 

 but the apex of the fore wing and the whole surface of the hind 

 wing light ochraceous yellow, not ochraceous brown; the black 

 discal spots on fore wing much larger. Antenna?, head, thorax 

 and abdomen as in the c? 



Exp. <J $ 62-78 mm. (2-46-3-10"). 



Hob. Europe ; Northern and Central Asia ; the Himalayas from 

 Chitral to Bhutan up to 10,000 feet ; descending in the North- 

 west of India to as low as Umballa (fide Lang},

cj . Upperside : white. Fore wing : cosla irrorated with black 

 scales for about two-thirds of its length from base, thence the apex 

 broadly, and the termen to vein 3 more narrowly, black, the inner 

 margin of the black area curved ; discocellulars with a crescentic 

 black mark ; a large elongate black spot in middle of interspace 3 

 produced outM'ards and coalescing with the black on the termen. 

 Hind wing: uniform. Underside: fore wing white, apex ochraceous 

 yellow ; the black markings of the upperside show through by 

 transparency. Hind wing : uniform ochraceous yellow. Antenna? 

 black speckled with white ; head, thorax and abdomen above 

 black, beneath white. 



Exp. 6 54 mm. (2-2"). 



Hub. Assam : the Naga Hills ; Upper Burma. 



This seems to be an extremely rare insect, only two specimens, 

 so far as I know, have been recorded ; the type from the Naga 

 Hills in the Indian Museum, and one taken in Upper Burma by 

 Capt. Watson, now in the British Museum.

^ $ . Closely resembles P. brassicce, from which it differs as 

 follows : c? . Upperside, fore wing : the inner margin of the black 

 area on apex and termen not smoothly curved but sinuate ; an 

 elongate narrow black spot, sometimes faint and ill-defined but 

 always traceable, in interspace 3. Hind wing : termen edged by a 

 narrow continuous black band that extends from the black costal 

 spot to the middle of interspace 3. Underside, fore wing : apex 

 aud upper portion of termen ashy-brown (by reason of the black 

 on the upperside that shows through by transparency), thickly 

 irrorated with black scales ; besides the black spots in interspaces 

 1 and 3 present as in P. brassicce, there is a third black spot from 

 middle of interspace 5 to vein 7 that extends above the latter vein
