This species, collected by Mr. G. H. Belfrage, in Bosque Co., Texas, Sept. 16th, differs from T. chrysellus by the broader, more olivaceous basal and median fasciae, narrowly united along the hind margin of the wing. The white fields of the primaries are thus less extended than in its congener. Subterminal line diffusely shaded with olivaceous, as is the terminal margin, leaving a whitish apical space. . Fringes whitish, thorax light olivaceous. Hind wings less purely white, with a terminal olivaceous shading.
