Evbner, Verz. bek. Schmett. 37. (1816). 



Vanessa Fabr., God'., Boise!., fyc. 



Head densely clothed with long hairs ; a distinct tuft of hairs outside the base of the antennas. 



Eyes oval, moderately prominent, hairy. 



Maxilla' slender, scarcely so long as the thorax. 



Labial Palpi porrect, slightly ascending, projecting considerably beyond the forehead, scaly, and 

 densely clothed with long hairs in front, and also behind, except towards the base ; the second 

 joint without any dorsal tuft. First joint subcylindric, curved, about two thirds as long as the 

 second ; second joint subcylindric, rather stoutest in the middle, truncate at the apex ; third 

 joint scarcely half the length of, and slenderer than, the second, tapering to a point at the apex. 



Antenna about two thirds the length of the body, rather slender, terminating in a short pyriform 

 club. 

 Thorax elongate, oval, hairy. 



Anterior Wings subtriangular ; the anterior margin but slightly curved ; outer two thirds the 

 length of the anterior margin, emarginate ; inner longer than the outer margin, slightly sinuate, 

 emarginate. Costal nervure stout, extending beyond the middle of the wing. Subcostal 

 nervure slender ; its first branch thrown off" before the end of the cell ; its second about at equal 

 distance beyond it ; its third about equidistant from the second and fourth. Upper disco-cellular 

 scarcely existing. Lower disco-cellular wanting, yet its position faintly indicated. Third median 

 nervule gradually curved. 



Posterior Wings subtriangular, all the margins about equal in length ; the anterior and outer 

 margins curved, the latter sinuate, slightly dentate; inner margin slightly emarginate above the 

 anal angle. Precostal nervure simple, nearly straight. Discoidal nervure separating from the 

 second subcostal nervule soon after its origin. Cell open. Third median nervule but little 

 curved. 



Anterior Legs of the male clothed witli long slender hairs. Femur and tibia slender; the latter 

 slightly longer than the former. Tarsus shorter than the femur, one-jointed, nearly cylindric, 

 tapering to a point at the apex. Anterior Legs of the female more elongate, scaly. Tibia 

 about three fourths the length of the femur. Tarsus nearly cylindric, fully as long as the tibia, 

 five-jointed ; all the joints, except the fifth, armed at the apex with a stout spine on each side. 

 First joint rather stoutest, one third longer than the rest combined ; second about two fifths the 

 length of the first ; third one half the length of the second ; fourth and fifth combined rather 

 more than equal to the third ; the fourth very obliquely truncate at the apex.
