developed. The female closely resembles coruscans W.-M. & de N. in the coloration 

 of the upperside. This is an interesting species, forming as it does a good " transit " 

 to the species amatrix de Niceville. 



The hue of the underside varies somewhat, as in centaurus Fab., being occasionally 

 washed with violet or grey, but it is always quite pale in tone. The species has been 

 known for years in the larger collections, having been placed either with amytis Hew. 

 or centaurus Fab., but Mr. Miskin discriminated it in 1890. Until this year it has 

 only been recorded from Queensland, but I have just received from Dr. Staudinger a 

 perfectly typical female from Tokal Key.

This species is a close ally of amantes Hew., but can be immediately distinguished by 

 the broad black borders of the male, while the blue is not nearly so deep and brilliant. 

 So far as is yet known, it is confined to Burma, but probably replaces Hewitson's 

 species there ; de Niceville seems also to intimate this in his original description, for 

 he says " True amantes apparently do not occur in Burma."

De Niceville (Butt. Ind. vol. iii. p. 240) says it is widely spread throughout India, 

 occurring " all along the foot of the Himalayas, in the plains of Bengal, the Central 

 Provinces, and in Bombay, thence southwards to Travancore and Ceylon. Its 

 flight is strong and rapid, and it conceals itself with wings always folded under leaves 

 (Hutchinson)." 



It is readily recognisable from ordinary centaurus Fab. by the brilliancy of the blue 

 and by the brighter females, but it is not so easily separated from coruscans W.-M. & 

 de Niceville. The blue is, however, deeper and more brilliant and the underside
