This species was in the Horsfield Cabinct, mixed up 
with H. intacta of Walker, from which it differs chiefly 
in the want of the central longitudinal white streak of 
primaries: the two insects may, I think, be variations of 
one species. 
2. Hypsa intacta. 
Hypsa intacta, Walker, Lep. Het. 2, p. 451, n. 10 
(1854).
