Forewing 11 to 25 mm. long in the male, 14 to 27 mm. long in the 

 female; lateral ocellus separated from the e3^e by about 3.5 its diameter; 

 head and thorax with numerous long suberect hairs, especially dense 

 in the male; clypeus of male with dense long suberect hair, that on 

 its basal part about 0.4 as long as the apical ^vidth of the clypeus; 

 clypeus of female with a subapical row of about 4 to 8 long suberect 

 hairs, above which are many shorter suberect hairs which are more 

 than half as long as the subapical row; nervellus joining the mediella 

 beyond the cubitella by about 0.7 the average width of the sub- 

 mediellan cell ; under side of last segment of female tarsi basally with 

 a median row of bristles that extends not more than 0.4 the length of 

 the segment, or the bristle row incomplete or absent; external longi-
