spotted with white, head slightly brownish, thorax and abdomen white. 

 Female similar, the black markings on the upper side of the fore wing on 

 the whole slightly broader, but not invariably so. 



Egg. — Cylindrical, slightly swollen in middle, becoming abruptly narrow 

 at top ; 13 longitudinal ridges of triangular section of which only six reach 

 the top where their ends, as minute teeth, surround the flat end. Colour 

 blue. H: l-2mm.; B: 0-5mm. 



Larva. — Head round, with very prominent, shiny, black eyes, covered with 

 black, short, stiff, semi-appressed bristles ; smaller than segment 2 ; colour 

 green. Body cylindrical, broadest at segments 4, 6 and 6, thinning off sud- 

 denly at segment 13. Anal segment narrow, square at end with a colourless, 

 curved, straight hair from each corner pointing backwards, rising from a cy 

 lindrical, white tubercle. The whole length of the body is lined transversly 

 by depressed lines at equal distances from each other ; between these lines 

 are rows of black, erect, short bristles surrounded at their bases by a circular, 

 green mark ; there is a single row between each two lines ; interspersed 

 among these bristles are a few white, cylindrical tubercles bearing, 

 each an erect, white, longish hair generally carrying at its tip a drop of 

 amber-coloured, transparent liquid; these long hairs are most numerous on. 

 segments 2, 12 and 13. Ventrum also haired at sides. Spiracles nearly 

 oval, very small and difficult to distinguish. Colour grey-green with 

 an indistinct, supraspiracular, dark line, below which is a whitish spiracu- 

 lar line ; a darkish dorsal line. L. : 17mm; B : 2*5mm. 



Pupa, — Head small, eyes nearly hidden by the broad base of the short,. 

 conical beak. The pupa is of the type of Terias hecabe. It is slight and 

 delicate-looking. Segment 2 broad and waved as to hinder and front 

 margins, flattish on top. Thorax short, humped, very slightly carinated, 

 as well as segment 2, dorsally. Sides from shoulders to segment 8 

 parallel. Part made up of head and segment 2 parallel-sided and 

 narrower than shoulders. Section of abdomen from segment 9 to end 

 circular. Constriction at segment laterally wide and slight, dorsally 

 ordinary. Cremaster stout, square, with a dorsal depression near hinder 

 margin. Apex of thoracic (ventral) expansion of wing cases, which is 

 parabolic, opposite segment 7. Spiracles oval, light ordinary in size. Na 

 spiracle of segment 2 visible. Surface glabrous, very minutely transversely 

 striated, shiny. Colour very transparent green, often suffused with pink -^ 

 a dorsal and lateral brown line the whole length of pupa, covered with 

 pink-brown spots obsolescently and sparsely ; a lateral row of black spotft 

 on segments 3 to 12, those on segment 5 exuding a black or white liquid 

 which dries like gum ; there is one spot laterally to each segment ; beak 

 yellow with a ring of 7 black spots half way up. L : 13'6 mm. ; B : 3 mm. 

 H. at apex of wing-bulge : 4'4mm.
