Quote from page 262: "Colorado is evidently the northernmost location of this species, which was originally described from Mexico (Eaton, 1892). Allen (1974) showed C. inornata as occurring in southern Colorado on a range map, but provided no specific information. Larvae reported from La Plata Co. by Peters and Edmunds (1961) are probably attributable to this species."
