ally, of which I have a series of twenty to twenty-five specimens 

 from Long Island (Israel Tepper) Chelsea Beach, Boston, Cape Cod, 

 Hampton Beach, N". H., Owl's Head, Maine, etc., and it is found, so 

 far as I know, only near the ocean ; while personata comes from Cen- 

 tral Illinois. The discovery of the male will settle the question of 

 its identity. 



Anterior wings dark gray, with all the markings present, but 

 confused, irregular and pulverulent ; costal, subterminal and anterior 

 half of median space lighter than the ground ; ordinary spots small, 

 the space between them dark; median shade distinct; subterminal 

 line very close to the exterior margin. Posterior wings dark gray, 

 with white contrasting fringes. Beneath, the anterior wings are 

 black with the costal light; the posterior wings white, with distinct 

 discal dots and a regular conspicuous subterminal line. Expanse, 

 30 mm.

 trasting; orbicular spot elliptical, with an outer black ring, within 

 which appears a white annulus, enclosing the gray centre; reniform 

 spot large and of the usual shape, the portion of its black annulus,
