straight line, from rather within the middle of the inner margin, to 

 a point on the costa two-fifths from the apex. A similar straight whitish 

 line originates on the costa near the apex and runs to about the middle 

 of the outer margin. The apical space outside this latter line is red- 

 dish-brown. There is a similarly colored semicircular spot at the anal 

 angle, margined inwardly with whitish. Fringes rather paler than the 

 base of the wing. 



Secondaries dark brown, somewhat darker than the primaries. 

 Fringes paler. 



Beneath concolorous with secondaries above, immaculate. 



Expanse of wings, i.oo inch ; length of body, 0.45 inch. 



Habitat. — New York (Edwards). Pennsylvania (Harris). 



For my specimen of this species I am indebted to my friend, W. H. 

 Edwards, Esq. It was accompanied by the cocoon from which it 

 emerged, but I have not been able to find any description of the 

 larva. The cocoon is brown, tough and smooth, broadly oval, almost 

 spherical, with the sides somewhat flattened, and the whole enveloped 

 in a thin flossy web. The imago escaped through a circular hinge- 

 like lid or cap. 



This species is much more thickly scaled than Z. scapha, and has 

 a softer, more velvety, appearance.
