Perina, "Walker, Catal. Lep. Het. Brit. Mus. iv. p. 966 (1855), $. 

 Male : forewing transparent from near the base, slightly elongated, costa arched 

 towards the end, apex pointed, exterior margin very oblique, posterior margin and 

 angle very convex ; first subcostal branch emitted immediately before end of the 

 cell, second from the end, trifid, the third from below the second at one-third from 

 its base, and the fourth at one-third from the base of third ; cell extending nearly 

 two-thirds the wing, upper end the longest ; discocellular bent close to upper end 

 and acutely inward below the middle, radial from the upper angle ; two upper 

 medians joined at their base and emitted from acute angle at lower end of the cell, 

 second at a short distance before the end, first or lower at more than one-third 

 before the end ; submedian slightly curved : hindwing short, broad, somewhat 

 quadrate, exterior margin slightly angular in the middle, abdominal margin long ; 

 apex transparent ; costal vein arched at the base, recurved ; subcostal slightly arched 

 before end of the cell, one subcostal branch only from end of the cell ; discocellular 

 bent acutely inward near upper end, lower end very long ; cell very long, lower end 

 extending five-sixths the wing ; two upper medians from angle at end of the cell, 

 second from a very short distance before the end, first or lower at one-fifth before 

 the end ; submedian and internal vein straight. Thorax moderately stout, smoothly 

 pilose, abdomen tufted at apex ; palpi small, porrect, slender, laxly pilose beneath ; 

 antennee broadly bipectinated, the branches decreasing to the tip ; femora and 

 tibiae pilose, middle and hind tibiae with two short terminal spurs. Female : forewing 

 entirely covered with scales ; elongated, exterior margin convex ; venation as in 

 male : hindwing longer than in male, exterior margin convex, abdominal margin 

 short ; cell extending to a little over half the wing ; two subcostal branches on a
