1. Polyhymno subaequalis, sp. n. 
Antennae whitish, slightly tinged with bronzy brown. Palpi whitish. Head white. Thorax white, tinged 
with bronzy brown along the middle. Forewings shining bronzy brown, with a broad white median 
streak from the base, attenuated to a point beyond the end of the cell where it nearly coalesces with a 
small elongate white spot beneath its apex, which is succeeded by a white triangular patch before the 
termen ; the lower angle of this is produced in a narrow marginal line along the base of the dorsal cilia, 
its upper angle also produced towards the apex, but shortly meeting, at an acute angle, two white costal 
lines, the one starting nearly from the base and leaving the costa beyond the middle, the other coming 
from the costa a little beyond it, and only slightly less oblique ; at the angle where they meet are some 
silvery scales; above the acute angle which they form are three, white, wedge-shaped costal streaks, each 
wider than the other as they approach the apex, the third, pointing inward through the apical cilia, 
separated from the second by a blackish streak and ornamented at its outer end by two minute black 
dashes in the extremity of the apical cilia, which have thus a caudate appearance ; the cilia below the 
bronzy brown pointed apex of the wing are also much ornamented, their base white in contrast with the 
narrow bronzy brown termen, some black spots lying along their middle beyond which their extremities 
are shining silvery grey; dorsal cilia dull greyish. Zap. al. 16 mm. Hindwongs and cilia greyish 
brown, the latter tipped with whitish around the apex. Abdomen brownish cinereous. 
the tarsi with four brownish spots.

The brown ground-colour of the forewings is distinctly more bronzy than in 5648
