I have received from Mr. Frank W. Langdon, of Madisonville, Ohio, a specimen (♀ ) of a new species of Botis, which I name Botis Langdonalis after its discoverer. It is one of the largest and most striking forms yet made known, and belongs to the group of flavidalis, with which it agrees in the general color of body and wings. The fore wings from base to first transverse line are clouded with fuscous, and stained with ochreous. The two discal marks are present, the orbicular a dot, the reniform a streak. The space between the exterior transverse or elbowed line and the subterminal line is much wider than usual, and this space is filled in with a broad fuscous band crossing the hind wings as well ; the lines are only indicated by the contrast of color
