 rounded, white, not projecting between eyes. Labial palps with third segment slightly less 

 than 1/2 length of second segment, upturned, almost reaching vertex. Thorax brown. Hind 

 tibia with outer spur of distal pair slightly more than 1/2 length of inner spur. Fore wing, 

 pattern as in PI. 9, fig. 42, brown with lighter, whitish brown areas. Small white triangle 

 subapically. Fringe light brown. Subterminal area pale whitish brown. Median fascia 

 darker near costa with several round yellowish brown areas in median fascia. Patch of darker

Genitalia $ (PI. 33, fig. 183). Uncus simple. Gnathus a thin sclerotized loop, with short 

 central process, lightly sclerotized. Juxta two simple rounded lobes, small median basal plate 

 with minute spines. Aedeagus with rows of cornuti. 



$. Unknown.
