Antenna} and palpi as in Halpe. Forewing, hinder margin longer than the outer 

 margin ; cell le.ss than two-thirds the length of the costa ; vein 12 reaching costa well 

 liefore end of cell ; middle discocellular considerably longer than the lower one ; vein 5 

 nearer to 4 than to vein 6 ; vein 3 from close to lower end of cell ; vein 2 a little 

 farther from vein 3 than 3 is from the end of the cell. Hindiving, outer margin 

 evenly rounded, vein 7 from well before end of cell, slightly curved, upper margin of 

 cell slightly curving downwards at the bifurcation, discocellulars slightly outwardly 

 oblique, very faint, vein 5 absent, vein 3 from near lower end of cell, 2 from about 

 one-fifth before the end. Hind tibiae with two pairs of spurs, the upper pair much 

 the shorter. Male without secondary sexual characters. 



Type, Pamphila masoni, Moore. 



Besides having no sex mark in the male, the base of vein 2 of the forewing is 

 nearer the lower end of the cell than it is in Halpe, and in the hiudwing the base of 

 vein 2 is farther away from the lower end of the cell ; this genus differs from Halpe in 

 about the same degree as Watson's genera Actinor and Onriza difier from Halpe ; 

 Onriza chiefly differs from Halpe in the nature of the secondary sexual character, 

 Actinor and Thvressa difier in being without any secondary sexual character.

Imago. — Male. Upperside blackish -brown. Forevjing with some dull ochreous 

 hairs on the basal portion and seven semi-hyaline white spots ; three small ones, sub- 

 apical, in a curve, the uppermost spot very minute ; two larger conjoined spots across 

 the cell towards its end ; two discal spots, one in each of the median interspaces, near 

 their bases, the lower one usually double the size of the other and quadrate. 

 Hindiving mostly covered with dull ochreous hairs, but without any markings. Cilia 

 of forewing brown, becoming pale towards the anal angle of the hiudwing, whitish
