General color a rather rich chocolate brown, often with a purplish or reddish 

 hue; palpi beneath, bright reddish brown : eyes golden. Thorax with the mar- 

 gins of patagise obscurely darker, more distinctly so towards the tip. Abdomen 

 with an indistinct double row of dorsal, dark brownish spots. Under side of 

 thorax and abdomen pale reddish brown, with a tawny line in the middle of 

 the ventral surface of the abdomen : yellow lateral dots on the hind portions of 

 the segments. Primaries with a decided rufous tinge in the middle and toward 

 the apex. An oblique, rigid, pale line margined on each side by a darker shade 

 line from costa two-fifths from base to the inner margin about one-third from 

 base; within this is a somewhat difi'use and indefinite pale line, which is curved 

 and still more oblique than the other; the costal portion of the interval between 

 this latter line and the base rather deeper, richer brown. Discal spot small, 

 black, narrowly edged with yellowish ; beyond this a series of four rather ob- 

 scurely defined dentate lines cross the wing, nearly parallel with the outer mar- 

 gin. A distinct richer brown shade runs from the costa above the discal spot to 

 the outer margin above the anal angle, filling the terminal space to the middle 

 of the space between veins three and four, and extending upward as a margin to 

 a curved line running from the costa near the apex to the outer margin between 

 veins three and four. This line is also margined inwardly with a deeper shade. 

 A bright reddish brown oblong spot on costa near the apex, Secondaries crossed 

 by a broad diffuse brown shade near to and i)arallcl with the outer margin, the 

 veins tipped with deeper, rich brown at the margin, the spots decreasing in size
