196 PIERIUJE. 



Hob. Assam; Cachar ; Burma; Tenasserim ; extending to Siam 

 and into the north of the Malay Peninsula. 



Race andamana, Moore. <f $ . Closely resembles the typical 

 form both in wet- and dry-season specimens, but is larger with 

 brighter colours ; the orange patch on the fore wing distinctly a 

 rich orange-red and proportionately narrower than in 1. verna. 

 The dry-season form (/. lena, Swinhoe) has the ferruginous discal 

 series of spots, and on the fore wing the reddish-brown tornal 

 patch characteristic of dry-season specimens, very conspicuous 

 and prominent. 



Exp. <$ 2 04-74 mm. (2-54-2-94"). 



Hab. The Andamans.

Wet-season brood. tf . Upperside : chalk-white ; apical half of 

 fore and terminal margin of hind wing broadly black, the black 

 on the latter broadest anteriorly. Fore wing: a broad rich 

 orange patch obliquely across the black area extended to the upper 

 apex of the cell, narrowed posteriorly and spread above the tornus 

 into interspace 1 ; opposite the apex of the cell this orange patch 

 is very broad and leaves only the apex of the wing and a compara- 

 tively narrow band along the termen and costa black ; base of the 

 wing irrorated with black scales. Underside : rich sulphur-yellow 

 as in most of the forms of the genus, irrorated with fusco- 

 ferruginous, short, transverse strigse and minute dots. Fore wing : 

 the orange patch of the upperside plainly seen by transparency 

 on the disc ; a broadly triangular area below the cell white ; 

 discocellular spot large and prominent, centred with white. Both 

 fore and hind wings with the discal transverse series of reddish- 

 brown spots, in other forms characteristic of the dry-season 

 broods, present and more or less conspicuous, the spots always 

 centred with white ; on the fore wing the patch above the tornus 

 prominent and in some specimens very large. Antenna? reddish 

 brown, head and thorax anteriorly with reddish-brown hairs, thorax 

 above with white hairs, abdomen black ; beneath : head, thorax and 

 abdomen white. $ Upperside : similar. Fore wing : the orange 

 patch on the black apical area narrower, posteriorly truncate, not 

 extended below interspace 2 ; an outer transverse series of four 

 black spots on the orange parch in interspaces 2 to 5. Underside : as 

 in the d , the markings slightly larger. Antennae, head, thorax 

 and abdomen similar. 



Dry-season brood In both sexes this differs less from the wet-
