Type-locality. — Vienna, Virginia. Described from one male re- 

 corded under Bureau of Entomology No. Hopk. U. S. 10161. This 

 specimen was reared from a larva which Avas collected on Gastanea

 is an edge eater; in the last feeding stage it is yellow with black 

 lateral spots; it is about 20 mm. long; in the prepupal condition it 

 is pinkish with black stigmatal spots and a faint, small blackish 

 subdorsal spot on each segment ; head pale.

 third transverse cubitus is not about twice the length of the second 

 transverse cubitus and is not bowed; the second joint of the hind 

 tarsus is much longer than the third; abdomen is deep black; the
