answering to his description. The genital characters are such, liowever, 

 that I think it may be considered a new species, for wliich I prp*]5ose the

 Say, which appear to me sufficiently definite for separation. Lack of 

 material has prevented me from making tl>e detailed study necessary to 

 indicate them minutely, but careful examination of my single specimen 

 leaves no doubt as to their presence./'

 abdomen and legs shining iridescent green. Basal half of front wing and 

 outer half along costa black or very dark brown, heavily overlaid with 

 iridescent green. The dark basal half is outwardly margined by the 

 black ground colour, owing to absence of the iridescent scales at th.is 

 point. All the outer half of wing, except the dark costal streak, is dull 

 ochreous, inwardly margined by a pale yellow line, the latter adjoining 

 the dark line of ground colour outlining the basal half. The ochreous 

 and yellow touch the costa at the middle only, and the ochreous 

 shade encloses the dark costal patch, the latter divides the apex and is 

 one half the width of the wing except at its inner end where it is rounded
