Body long and slender. Head longer than in Acidalia; front very long 

 and full," broad, where that of Acidalia is narrow and sunken between the 

 eyes. Antennae of the male broadly pectinated, plumose. Palpi long and 

 slender, extending well beyond the head; third joint very long and slender. 

 Eyes not so large and full as in Acidalia. Wings large; lore wings falcate, 

 eosta very full, apex sharp, outer edge much hollowed below the apex, scal- 

 loped ; hind wings square, the angle in the middle of outer edge produced into 

 a long sharp point, the edge scalloped, inner angle square. Venation: much as 

 in Acidalia, the subcostal cell longer and the outer end squarish, the first sub-
