190 PIERIDJE. 



palpi ochraceous with some black hairs, thorax ochraceous brown, 

 abdomen white. ? . Upper and under sides : very similar to those of 

 the wet-season ? , but the blackish-brown colouring on the upper- 

 side paler and duller in tint. Underside: differs in the yellowish- 

 green suffusion on both fore and hind wings, which is replaced by 

 ochraceous brown. Antennae, head, thorax and abdomen as in 

 the c?. 



Exp. 3 $ 58-74 mm. (2-28-2-92").

liace andamana, Swinhoe. A slightly differentiated but, 

 because insular, very constant form. The <$ may be discriminated 

 from the wet-season form of typical nadina as follows : on the 

 upperside by the greater extent of the black on the apex and termen 

 of the fore wing ; on the underside of the same wing, by the width 

 and prominence of th& black inner border to the greenish-yellow 

 area on the apex ; on the hind wing by the reduction of the 

 white markings to a large yellowish-white spot on the discocellulars, 

 also by the greater prominence of the broad dark discal band. 

 These differences seem constant. The $ is a much lighter 

 coloured insect on the upperside than the $ of typical nadina. In 

 fact it closely resembles its own c? , but differs as follows : 

 Upperside : base broadly of both fore and hind wings and the 

 greater portion of the latter wing also, posteriorly dusky-grey and 

 irrorated with black scales ; black on apex and termen of fore 

 wing more extended ; it commences on the costa above and reaches 

 the upper apex of the cell. On the hind wing the anterior veins 

 are broadly black-margined towards their apices, where they form 

 an irregular anterior black terminal band. Underside : precisely as 

 in 'the rf 



Exp. d $ 64-73 mm. (2-52-2-88"). 



Hab. The Andamans. 



There seems to be no dry -season form corresponding to that in 

 typical nadina, but certain specimens taken in March and April 

 have the black on the upperside of the fore wing much restricted. 



liace remba, Moore. Wet-season brood. J $ . Eesembles the 

 wet-season brood of typical nadina, from which it differs as 

 follows: J . Upperside: ground-colour similar. Fore wing: outer 

 half from the middle of the costa obliquely, to before the 

 tornal angle, intense black, the base with a bluish shade. Hind 

 wing : base, terminal margin broadly below vein 5 and costal margin 

 above vein 6, irrorated with black scales ; termen anteriorly from 

 apex to vein 4 decreasingly black. Underside : white, costal margin 

 and apex broadly suffused with greenish yellow ; a large prominent 

 bright yellow preapical spot, below which is a larger black irregular 

 patch angulated at and touching the lower apex of the cell. Hind
