<3 . Upperside : dark purple, sometimes fuliginous, sometimes 

 bright and shining. Fore and hind wings : terminal margins 

 edged with fuscous brownish-black and an anticiliary jet-black 

 line ; cilia brown ; tail black tipped with white. Underside : more 

 or less dingy white. Fore wing : a broad oblique brownish- 

 black band from base to just before the middle of the costa; 

 from the latter a dark brownish-black bar proceeds vertically 

 down to middle of interspace 3, on the inner side of this and 

 touching it in the middle is a large brownish-black irregular 

 spot that extends posteriorly to vein 1 ; beyond this a broad 

 discal transverse brownish-black band twice interrupted, the 

 posterior portion slightly narrowed below is shifted obliquely 

 inwards and ends on vein 1 ; this is followed by a postdiscal 

 transverse series of brownish-black spots that anteriorly nearly 

 coalesces with the discal band, a transverse subterminal line of 

 similar but smaller spots and a well-marked anticiliary black line. 

 Hind wing : a basal short, brownish-black, anteriorly attenuate 

 bar placed obliquely, a transverse subbasal band of four large 

 coalescent black spots, a transverse curved discal band twice 

 broken as on the fore wing and similar postdiscal subterminal 

 and terminal markings. Antennae black, shafts ringed with white, 

 head, thorax and abdomen dark brownish-black ; beneath : the palpi 

 black, thorax and abdomen down the middle white. $ . Upper- 

 side : fuscous black. Fore and hind wings : in most specimens 

 the markings of the underside show (sometimes very conspicuously) 

 through. Underside : as in the d 1 . Antennae, head, thorax and 

 abdomen similar to those of the cf . 



Exp. c? $ 22-30 mm. (0-85-1-18").

Larva. " Like that of C. rosimon feeds only on the parenchyma 

 of the leaf ... . It is of the usual woodlouse form, slightly 

 flattened head concealed in the second segment ; surface more or 

 less rough ; a fringe of long white bristles all round with an 

 erected ridge of similar bristles along the back from the second 

 segment ; those on the 3rd and 7th segments and the last two 

 much longer than the others ; those on the 2nd segment very few, 

 short and black. It has a conspicuous gland on the 12th seg- 

 ment, and is attended by small species of ants o the genus 

 Cremastoyaster. Its colour is pale green, the dorsal portion of the 

 2nd, 4th, 5th, 6th and last two segments being dark brown, while 

 the centre segments are almost yellow with a darker dorsal line. 

 We found it feeding on Zizyplms xylopyrus and also on Loranthus, 

 where it was attended by Cremastoyaster ants." 



Pupa. " Of the usual Castalius form but narrow and slightly 

 flattened. It is intensely glossy as if covered with gum. It 

 varies in colour, being sometimes black, at others green with 

 inconstant black markings." (Davidson, Bell $ Aitken.)
