similar spot crowned inwardly with ochraceous and irrorated 

 outwardly with a few metallic blue scales ; a very slender terminal 

 white line not extended to the apex and an anticiliary dark line. 

 Antennae black, shafts minutely ringed with white ; head, thorax, 

 and abdomen dark brown ; beneath : the palpi fringed with black 

 hairs, thorax fuscous, abdomen dull white. $ . Upperslde : dull 

 leaden blue. Fore and hind wings : anticiliary slender black 

 lines as in the J , within which on the fore wing is an obscure 

 transverse subterminal series of black spots ; on the hind wing a 

 very slender terminal white line, a subterminal row of black spots 

 and a postdiscal series of white lunules, the spots decreasing in size 

 and the lunules obsolescent anteriorly. Underside : ground-colour 

 paler than the markings, more obscure but identical with those of 

 the d 1 . Antennae, head, thorax and abdomen as in the c? but all 

 paler in colour.

d 1 . Upper side : plumbeous blue. Fore and hind wings : anti- 

 ciliary jet-black lines ; on the hind wing subterminal subequal black 

 spots in interspaces 1 and 2, beyond which there is a terminal 

 white thread that does not extend beyond those two interspaces. 

 Underside : f rench-grey ; principal markings chalky-white, some- 

 what diffuse. Fore wing : a pair of short transverse white lines 

 across the middle and another pair at the apex of cell, one on each 

 side of the discocellulars, these latter not extended to the apex but 

 in most specimens indicated there by two white spots ; a complete 

 transverse catenulated discal band composed of two parallel 

 white lines, beyond which the ground-colour looks as if it 

 had been chalked over; the terminal markings however, though 

 blurred consist of an inner and an outer transverse series of white 

 lunules succeeded hy an anticiliary white line. Between the 

 transverse pairs of white lines, medial and discal, and between the 

 subterminal series of lunules, the ground-colour is distinctly 

 darker, between the latter and the anticiliary line it takes the 

 appearance of an incomplete transverse row of dark spots. Hind 

 wing : the following transverse white, somewhat indistinct lines : 

 two basal, a single line on the inner side of: the discocellulars, two
