(S . Upperside : pale lilac-blue. Fore and hind wings : a very 

 slender black terminal line even in width from apex to tornus 

 on each wing ; centre of the disc of the fore and upper discal 

 area of the hind wing pale, in specimens of the dry-season broods 

 turning to white. Underside : white with a very faint bluish tint 

 in fresh specimens, markings very delicate and slender in shape 

 and in the position usual in all the forms belonging to the genus ; 

 the inner subterminal transverse lunular line on both fore and hind 

 wings. Fore wing : the postdiscal series of markings very slightly 

 oblique, slightly closer to the terminal margin posteriorly than 

 anteriorly, the abbreviated lines or elongate spots composing it 

 en echelon one to the other. Hind wing : the subbasal transverse 

 series of three black spots and the subcostal spot in interspace 7 

 not much larger nor very much more prominent than the others. 

 Antennae, head, thorax and abdomen brown, the antennae ringed 

 with white as usual ; beneath : the palpi, thorax and abdomen 

 white. $ . Upperside : white, tinged with lilac at the bases of the 

 wings. Fore wing : costa, apical third of wing and termen very 

 broadly brown. Hind wing : the anterior third from a line that 

 passes from base through the upper portion of the cell to the 

 termen, brown ; a subterminal row of rather distinct brown spots 

 enclosed between a series of obscure lilacine lunules and a black 

 anticiliary line. Underside: ground-colour and markings as in 

 the c? , but on the fore wing the transverse postdiscal series of 

 markings placed comparatively more inwards. Antenna?, head, 

 thorax and abdomen similar to those of the c? 



Exp. c? $ 30-34 mm. (1-18-1-34").

c? . Upperside : purplish -blue or lilac of a deeper shade than 

 in C. dilecta. Fore wing : a much broader dusky black ter- 

 minal margin that widens at apex and is somewhat diffuse along 

 its inner edge. In specimens of the dry-season brood there is a 

 diffuse but prominent discal white patch. Hind wing : costa dusky 

 brownish ; termen with a comparatively narrow black border 

 edged on the inner side by a more or less obscure subterminal 

 series of black spots, each spot centred in a background which is 

 slightly paler than the lilac ground-colour. Underside : pale greyish- 

 white or bluish-white, with the usual pale brown markings which 

 are small, delicate and regular. Antennas, head, thorax and
