Agrotis nanalis, n. s.
♀. The smallest species known to me. All the tibiæ spinose ; eyes naked; body untufted. A slender species which may be compared with opaca. The fore wings are blackish with the lines lost. The stigmata are concolorous, difficult to make out. The orbicular is elongate, the reniform vague, upright, broad; the spots are picked out by a brown shading which fills the cell and marks the subcostal and median veins.
