Dry-season brood — <S $ . Upperside : fore wing : the black on apex and 

 termen much restricted, the lower, subterminal black bar generally absent ; 

 the veins white, concolorous with the ground-colour, so that the bar 

 between veins 3 and 4 does not coalesce with the black on termen. In 

 the extreme dry-weather broods, this bar becomes obsolete. Hind wing : 

 uniform dead white, sometimes the apices of one or two of the anterior 

 veins with a little black scaling. Underside : the veins, except those that 

 limit the cell of the fore wing, not bordered with black ; the suffusion of 

 yellow along costal margin, on apex of fore wing, and over the whole surface 

 of the hind wing pale yellow, with a tendency in the extreme dry-season 

 specimens to become almost white ; on the fore wing, the black, transverse 

 subterminal bars between veins 1 and 2, and 3 and 4 are sometimes indi- 

 cated by mere diffuse small patches of scales ; at other times they are 

 absent. Antennse, head, thorax and abdomen in both seasonal broods much 

 as in the typical form, but paler. Expanse : 44-56 mm. 



Typical S. nerissa does not seem to have been bred ; it is found in 

 Nepal, Sikhim, Bhutan, Bengal, Assam, Upper and Lower Burma, Tenas- 

 serim ; also in Siam and China, There is a race or species called 

 a. lichenosa, Moore, inhabiting the Andamans which is distinguished from 

 a. nerissa by the fact that the dusky black markings along the veins on 

 the underside of the hindwings occupy more of the area than the ground- 

 colour, while in nerissa, it occupies less. 



The Bombay form of Iluphina nerissa is phryne. It has been bred and 

 the history is as follows : — 



Larva. — The first two stages are oily yellowish green with a black head, 

 all the tubercles prominent and comparatively large to what they become 

 later on. 



Third stage. — Body cylindrical, ending somewhat narrowly at anal end 

 in two rounded knobs which bear longish white hairs, one on each side of 

 dorsal line. The head is round, as broad or slightly broader than segment 

 2, the surface rough with minute tubercles, each one bearing a brown or 

 white bristle-like hair, 2 or 4 tubercles on each lobe larger than rest and 

 bearing each a longer hair which points forwards and slightly down. The 

 surface of the body is transversely impressed, lined with 7 fine parallel lines 

 to each segment, each inters^al between every two lines having a single, 

 central row of minute white tubercles, each tubercle bearing a short hair 

 or bristle ; the main tubercles ( one subdorsal, one dorsolateral and one 

 supraspiracular as usual ) being very little larger than others but bear each 

 a somewhat longer hair which often bears a globule of transparent, clear 

 liquid at its tip ; the whole surface is, besides, clothed with extremely 

 minute, brown, erect hairs ; the bristles on segment 2 perhaps longer than 

 on other segments ; a fringe of rather long, fine, white hairs all round the 

 body on the subspiracular and lateral ventral regions. Colour of body dark 

 green ; belly much lighter, grey-green. 



Fifth stage. — Nearly the same as the 4th. Body cylindrical ; anal segment 

 narrow behind, slightly thickened at extremity, the extremity being coarsely 

 bilobed, each lobe short, rounded. Head rounded, face somewhat flattened, 

 slightly less in diameter than segment 2 ; surface finely rough with many, 

 small, white, conical, glassy, setiferous tubercles which are most numerous 

 on the upper portion, the setee erect, brown ; one, dorsolateral, longer than 

 rest, just below vertex of each lobe ; lower part of face sparsely covered 

 with fine, white, erect setfe. The surface of body is transversely lined as in 

 last stage, the intervals with a central row of small, white, conical tuber- 

 cles, bearing each a brown, short hair ; whole surface covered with minute, 

 red-brown tubercles, each bearing a short brown bristle ; subspiracular 

 regions set with long, fine, erect, white hairs forming a fringe round body,
