Female, Upperside: similar to that of the male, but the median white trans- 

 verse band across both wings broader, extended on the foro wing up to 

 vein 7 (or not) and with no inner edging of blue or iridescent light blue 

 irroration ; the black at the bases of the wings and on the margins not so 

 intense in shade, more of a brownish-black. Underside t groun'J-colour 

 and markings very similar, the basal two oblique bands on the fore wing 

 generally farther from one another than in the male. A thread-like tail 

 at end of vein 2 of hind wing, black tipped with white. Expanse : Male and 

 female, 28-i}l mm. 



£!(/ff. — Turban-shaped. The surface is only slightly shining ; divided up 

 into irregular, hexagonal cells by coarse walls which are lowest on top of the 

 egg and nearly triangular, also smallest round the central micropyle ; the 

 intersections of the walls each with a rounded, raised knob ; the bottoms of 

 the cells flat and minutely pitted ; sides of the hexagonal cella often of 

 different lengths, sometimes nearly O so that two knobs nearly coalecesce, 

 or even 3 at times ; the rows of cells are diagonal and slightly curved, 

 about 4 of them from the triangular cells of the top of the egg to the base 

 — 7 or 8 small ones surround the micropyle. Colour : green nearly obscured 

 by the whita knobs and ridges. B. O. 70m-m. 



Larva. — The shape is more or less normal though considerably depressed, the 

 dorsal region quite even except that the segment-margins are quite distinct 

 and except for the depression on dorsum of segment 2 ; this depression is 

 somewhat indistinct and quite smooth at the boitom ; segment 2 is semicir- 

 cular in shape ; the anal end is broadly rounded and not in the least flat- 

 tened, its extreme margin perhaps slightly tumid. The head is hidden in 

 repose under segment 2, green in colour, shining, rather small, the eye 

 region jet-black, mandibles light red-brown tipped ; antetinsB, labrum 

 whitish, ligula with a red-brown tinge. Spiracles hardly visible, being sunk 

 in slight depressions, small, round and whitish in colour. /Surface of body 

 is shagreened silvery-white all over because of a dense covering of 

 short, thick, silvery-translucent hairs, generally appressed, sometimea 

 erect, sometimes thickened in the middle, sometimes double, always 

 extremely short ; these thickened hairs disposed all over the dorsal half- 

 somites, most densely on segments 2 and 3 ; rather shorter and sparser 

 on the green, dorsal line ; down each side of the green, dorsal line is a 

 row of 4-6 long and slightly up-curved bristles or hairs mixed with 

 an equal number of shorter ones on each segment ; all these bristles 

 being light red-brown in colour ; also a submarginal (dorsoventral) row 

 of light red-brown slightly longer, down-curved hairs, about 12 to each 

 segment. Colour : light grass-green with a broad, dorsal, dark-green line 

 from front margin of segment 3 to hinder margin of segment 12, flanked on 

 each side by a still broader, light yellow band, below which the body m 

 light grass-green. There is no sign of gland on segment 11 or organs on 

 segment 12. L: 13 mm. B: 3 mm. 



Pupa. — Is normal in shape, like those of the other members of the genus 

 Castalius. The head is high, that is the frons is vertical with part of the 

 vertex of which a very small portion is visible above before the front 

 margin of segment 2, this margin being more or less straight; the thorax 

 is rounded and humped, nearly hemispherical as regards the dorsal 

 portion of the somite ; the abdomen is also convex about segments 8, 9 where 

 the body is fattest both in height and diameter ; there is a wide, though 

 rather accentuated constriction at segments 4, 6 ; the anal end is somewhat 

 ^arrowed and rounded. Spiralcs of segment 2 are longly oval and white 

 in colour ; the rest are small, inclined to be semicircular and are also 

 white. The surface is clothed all over with short, erect, white hairs, 

 longest at anal extremity and on segment 2. The colour is green touched
