Forewing. — Cream-color; the lines and shadings and the veins toward 

 hind margin dark brown; costa diffusel}^ dark brown; the lines all 

 fine; an oblique line close to base, followed by a brown spot in cell; 

 beyond this the usual basal line is strongl}^ outcurved, running base-

 dentate from three-fourths of costa to a blotch at anal angle; the teeth 

 on veins 6 and 4 especially projecting; it is preceded by three brown 

 less concave shades parallel to it, before the innermost of which is the 

 linear brown cell mark, occupying the whole length of the discocellular; 

 the inner margin from basal line to the outer of the three shades is 

 brown up to the submedian fold; submarginal line thick from seven- 

 eighths of costa to middle of hind margin, blotched at both ends; 

 marginal festoon brown; fringe cream-colored, mottled with brown.

Under side cream-colored flushed with dull reddish; the lines marked 

 but obscure, except toward hind margin; apical half of hind margin
