This species, which in all the later lists has been placed in the genus Euxoa, will have to be transferred to Agrotis on the strength of the male genitalia which are typical of this latter genus; the front, furthermore, is only slightly bulging and roughened and does not show the tubercle with raised edges characteristic of most of the Euxoa species.

Form elongate oval, moderately convex. Colour bright blue-green with slight iridescence, purplish reflections predominant, shining. Antennae and legs rufotestaceous. Thorax and elytra finely but distinctly punctured, distinctly alutaceous.

So little has been done or published on Mississippi Rhopalocera that it seems desirable to present a short list. In this list I have included only those species and forms which I have actually collected or seen in the collection at State College.

Female. Length 5.5 mm.; width 2.8 mm. Dark reddish-brown, the antennae, legs, and side margins of the pronotum and elytra paler.
