The form violacea of Edwards seems clearly to be the one described and 

 figured by Boisduval and Le Coute, under the name of Pseudargiolus. North 

 of the southern boundary of New York, the female is always blue.

I have i)laced this and the following species apart from each other, and from 

 pseudargiolus ; yet I cannot help sharing a common opinion (to which Mr. Ed- 

 wards' experiments have given birth) that we shall not be sure of our ground 

 until the complete history of every form is known. See Can. Ent. 8, 61-0.

This genus is very closely allied to Cj-aniris, though its general appearance 

 is very distinct. The club of the antennae is somewhat slenderer. The fore 

 tibiae are four-fiftlis, and the middle tibiae five-sixths the length of the hind 

 tibiae. First supt^ior subcostal nervule of fore wings arising at scarcely three-
