HYEMINA, Walker. 
Hyrmina trailii, n. sp. (Plate XIX. fig. 9.) 
Resembles Leucothyris astrea and is nearly allied to Hyrmina cyma, from wliicli it chiefly 
differs in the absence of the subcostal orange spot in primaries and the different form of the 
subapical hyaline streak. Wings hyaline, black-veined ; primaries with the borders black- 
brown; two oblique brown bands, the first across the middle of the wing, the second (broader) 
towards apex : secondaries with costa brown ; outer margin black-brown, enclosing a well- 
defined submarginal orange streak. Body brown ; abdomen with a dorsal whitish line ; 
venter whitish. Expanse of wings 1 inch 6 lines.
