Male. Very similar to serraticoris Lint., but on the whole more contrastingly marked on the forewings, the light purplish-gray color being replaced by a whitish gray, heavily suffused with smoky; t. a. and t. p. lines poorly defined, much as in serraticornis, the former showing the usual sharp angle, outlined by a dark streak, above vein I and the latter in this same area with the usual small dark patch, closely approached to t. a. line and separated from it by a palish area. Rather heavy blackish suffusion in median area along inner margin.
