In 1875 (Ann. Lyc. Nat. Hist. N. Y. XI, 108) Grote erecied the new genus Agrotiphila, based on a male specimen collected by Theo. Mead in Colorado and which he had determined as montana Morr. (1875, Ann. Lyc. Nat. Hist. N. Y. XI, 95). His characterization of the genus is as follows: “All the tibiae are spinose. The shape of the abdomen and habitus is as in Anarta. The eyes are naked, encroached upon by the caputal tegument, ovate, narrowed, fringed with lashes, the thorax is thickly and coarsely haired, without tufts. The maxillae are stout. The antennae are simple, thickly ciliate beneath in the male.” Under the specific heading he notes that “my specimen, numbered 28, agrees very well with Mr. Morrison's description, except that the whitish orbicular is open superiorly, somewhat trianqulate, and that the discall marks beneath and on the hind wings above are illegible.” (The italics are mine).
