Ozarba fannia. Barnes and McDunnough (1913a) identified material of Ozarba Walker from western Texas as Ozarba fannia (Druce), but later (Barnes and McDunnough 1913b) reidentified it as O. aeria (also as O. aeria in Franclemont and Todd 1983). The holotype of Ozarba fannia from Mexico is a form in which the forewing ground color is reddish brown and this form occurs northward to Arizona and western Texas, whereas typical material of O. aeria from eastern United States (including the holotype of Ozarba aeria from Wisconsin) has a gray-brown forewing. Both forms occur together in many areas of western United States and we see no evidence that they are more than color forms of a single species.
