of the hindwing may be either entirely yellow (a <$ from Bolivia) , yellow with dark 

 distal band, or almost entirely brownish grey (see description) (5 $ from Peru). 



The type of asara is almost identical with that of flavescens and its genitalia are 

 nearly identical to those of a male from Para. (The abdomen of the type of flavescens 

 is lost.)

Similar to flavescens in many features but distinguished by the following charac- 

 ters. Dark marking on forewing unicolorous (not enclosing yellow area at anal 

 margin of wing), its proximal margin nearly parallel to longitudinal axis of moth. 

 Tarsal segments 2-5 of each leg orange-yellow; segment 1 orange-yellow with distal 

 band of greyish brown. Hindwing yellowish white; more yellowish at apex and 

 anal area, and with pale yellowish brown suffusion in posterior half of wing. (The 

 dorsal surface of abdominal segments 1-5 in both examined specimens is greyish 

 brown.) In the male genitalia the valve is shorter, bears a longer medially directed 

 process, and the vesica is distinctively ornamented. 



The female is unknown.
