The antenncE and palpi of the male are black ; head ochraceous ; 

 thorax and abdomen black tinged with brown, varied with an 

 ochraceous colour. Anterior wings with two large diaphanous 

 spots near the apex, between the second, third, and fourth ner- 

 vures ; the general colour black, varied with gray and ochra- 

 ceous, in the form of waved transverse bands ; the posterior 

 wings black, with the hinder portion varied with ochraceous, 

 and a longitudinal whitish band across the middle ; also a waved 

 bright ochraceous band near and running parallel with the 

 outer margin. 



The lower surface of the fore wings black, with the outer half 

 and anterior margin mixed with gray, and an oblique transverse 

 vdiitish band across the middle ; also two white spots in the 

 discoidal cell, the former nearest the base small and round, the 

 latter somewhat lunate near the band ; the nervures near the 

 outer margin ochraceous. The lower surface of the posterior 

 wings also black, thickly clothed with whitish or ash- coloured 

 scales, with a waved black band and a row of black sjiots, one 

 on each nervure, both of which cross near the middle. 



The colour of the female insect is universally much lighter, being 

 of an ash varied with gray ; the dark uneven marginal band 

 across the middle of the anterior wing is more apparent, but the 

 ochraceous waved band on the lower wings of the male is 

 scarcely visible in this sex.
