184 Messrs. J. J. Joicey and A. Noakes on 



marginal row of 7 large rounded spots, the first two the larger, pale 

 orange, in 6 and 5, others white. 

 Length of fore wing : (J $ 31 mm. 



A series. 



Since the descriptions of the sexes of this species were 

 written, we have received a pair taken in cop. 



11. Appias albina pulverobasalis, subsp. nov. 

 (Plate XXIII, figs. 5, (^, 6, ?.) 



(^. The base of f orewing and less so the base of hindwing is suf- 

 fused with dark scaling above. Costa of forewing much more 

 thickly scaled. 



$. There are five forms in the series sent. Of the typical white 

 forms there is principalis, Fruh., and semiflava, Fruh. The yellow 

 forms comprise flava, Rob., and two which seem to be intermediate. 

 One of these is similar to flava but larger and base of forewing more 

 scaled with yellow. The other is similar but darker at base of 

 forewing, no apical spots, and a wider marginal band on hindwing. 



We figure this form. The latter and the form semiflava 

 were taken in cop. with the i^ form above described. A 

 long series of both sexes, but only a few of the yellow 

 $ forms, 



12. Appias ega falcidia, Fruh. ,^. 



(Plate XXV, figs. l,<$,2, ?.) 



Seitz, "Macrol." ix, p. 156. $. Smith, Nov. Zool. 

 1, p. 337, as saina $. 



Similar to saina, Sm., which has not yet been properly described, 

 as Smith's " (J '* is a $. Apex and costa narrowly margined with 

 black, veins at apex black at ends and a certain amount of black 

 suffusion between them. Some dark scaling along costal margin 

 increasing at base. The black spots which occur in 3 and 4 as in 

 ega are sometimes quite absent or the one in 2 is much enlarged; 

 there is a tendency for the spot in 4 to become obsolete. 

 Underside with apex, base of forewing and whole of hindwing 

 sulphur yellow. 



A 9 specimen differs from the others in the absence of apical 

 spots on forewing above, a narrower margin on hindwing, and 

 below with apex and distal margin of hindwing brown without any 

 yellow suffusion. 



A series of both sexes.
