 the angle ; lower radial from the middle, upper radial from near 

 the top of the discocellular ; 3rd, 4th, and 5th subcostals on a 

 common stem fi-om upper angle of cell ; 5th leaving at g, 3rd at f , 

 4th into apex; 1st and 2nd subcostals free. Hind wings with 

 upper half of discocellular vertical, lower oblique ; 1st median at f, 

 2nd at |, 3rd from lower end of cell, which is wedge-shaped; 2

S . Pore wings pale green and dull amethyst, with darker trans- 

 verse flecks ; basal patch dark brownish amethyst, its outer edge 

 distinctly angulated in middle and edged with darker ; the extreme 

 base of the costa green ; central space pale green, broadening along 

 the costa and inner margin, constricted in middle opposite the 

 angle of the basal patch, containing between the veins sundry small, 

 irregular, semitransparent whitish patches ; marginal area dull 

 amethyst, edged internally by an irregularly dentate darker shade, 

 which represents the 2ncl line and curves outwards towards the 

 anal angle, and containing a thick blackish oblique line from the 

 anal angle to the greenish spot which occupies the apical region ; 

 all the veins, where they traverse the green spaces, deeper green. 

 Hind wings similar, but with the central green space restricted 

 and not reaching the inner margin ; fringes concolorous with the 

 green and amethyst sections of the wing. Head, face, and collar 

 greenish ; thorax and abdomen mixed fuscous and amethyst ; 

 antennae, anal tuft, tibiae, and tarsi ochreous, dotted with darker ;
