CASTALIUS. 425 



and two, each pair coalescent and placed en echelon, the latter of a 

 transverse double series of subterminal black spots and an anti- 

 ciliary black line ; the upper portion of the postdiscal markings 

 touches the inner subterminal line. Cilia of both fore and hind 

 wings white alternated with black at the apices of the veins ; 

 filamentous short tail to the hind wing black tipped with white. 

 Antenna?, head, thorax and abdomen black, the shafts of the 

 antenna ringed with white, the head between the eyes and behind 

 them white ; beneath : the palpi, thorax and abdomen white, the 

 last barred broadly with white on the sides. $ . Similar to the 

 c? but with the black markings on the upper and under sides 

 broader. 



Exp. rf $ 28-34 mm. (M 0-1-34"). 



Hob. Peninsular India south of the outer ranges of the Hima- 

 3, except in desert tracts ; Ceylon ; Assam ; Burma ; Tenas- 

 serim ; the Andamans ; Nicobars ; extending into the Malayan 

 Sub region. 



C. rosimon varies both seasonally and locally according to the 

 amount of dryness or moisture, but the variation occurs in the 

 width and not in the actual character or shape of the black 

 markings on the wings. Some specimens taken in the rains in the 

 Andamans in my collection are the darkest I have seen. In these 

 the markings on the upperside of both fore and hind wings have so 

 spread and joined on one to the other that very little of the 

 ground-colour is left. This consists on the fore wing of a broad 

 medial irregularly shaped transverse white mark that extends from 

 vein 6 sinuately to vein 1 and on the hind wing of a transverse 

 narrow medial band of white from vein 7 to the dorsal margin. 

 On the underside the black spots and bands though larger and 

 broader are proportionately not so much broadened as on the, 

 upperside. Between the ordinary form and the above described 

 extreme examples all gradations can be found in any long series. 

 The iutenseness of the black colour of the markings also varies. 

 In some specimens taken in the hot weather in the dry hot plains 

 of Pegu the colour of the markings is a dull brown both on the 

 upper and under sides. 



Larva. " Feeds on Zizyphus jujuba, and is of a rough texture as 

 if shagreened all over. It is of the usual woodlouse form, much 

 flattened towards the anal segment which is very broad ; head 

 concealed ; colour bright green with a double, dorsal, yellow line 

 and the sides powdered with small yellow spots." (Davidson, 

 Bell # Aitken.) 



Pupa. " Fastened by the tail along a leaf horizontally (the 

 band across the thorax being very lax). It is much contracted 

 at the thorax, while the abdominal portion is large and rounded 

 and much higher than the thorax. It is of a bright green with 

 faint yellow bands on the abdomen and two or three black spots 

 there. It also shows traces of a darker band in the centre of the 

 abdomen." (Davidson, Bell $ Aiiken.)
