Vertex and thorax with distinct double crests. 



Hoary and somewhat bluish gray. Head and thorax dark gray and paler on the sides, the latter with a 

 few short black lines, or with the disc before blackish brown, and a stripe of the same hue on the sides. 

 Abdomen dusky gray without bands, and two brownish dorsal lines. Anterior wings hoary, or gray tinted 

 with bluish, with blackish markings ; a blackish streak extending from base to the tip, and a short, nearly 

 parallel blackish streak above the interior angle ; a blackish patch on costa at the posterior extremity of 

 the disc, a fainter one about the middle, and another at the origin of the post-apical nervule ; a row of 

 black dots on the lower third of the nervures and another about the middle, each series being connected by 

 a faint acutely angled line ; a row of marginal, black dots in which terminate faint, slender, blackish lines 

 in the interspaces from the post-apical to the medio-central. Posterior wings rust-red or reddish fawn-color, 

 with a dark brown patch on the terminal margin, about the interior angle, and a series of indistinct dots 

 above the nervules. 



In the markings of the anterior wings this species bears a very striking resemblance to Fllo.
