Head and palpi blackish brown. Thorax concolorous, rather rusty brown, with a small metathoraeic 

 black tuft. Abdomen black, with dispersed bluish scales along the dorsum, with the basal segment banded 

 with brown and three large orange yellow spots on the sides of the basal segments ; beneath and between 

 these spots are short white marks. The legs and undersurface of thorax and abdomen blackish gray and 

 whitish in the middle. Anterior wings are brown in the greater part, separated by an exceedingly irregular 

 outline from a black costal portion covered with dispersed pale blue scales, and which is dilated from the 

 costa into an angular basal, a large nearly square median and an apical irregularly oval patch ; the brown 

 portion has two broad dilations toward the costa, both extending to the sub-costal nerve. The median 

 black patch contains a small white discal dot and is edged beneath and behind by pale brownish. The 

 post-apical nervule and sub-costo inferior are pale colored, and toward the termination of medio-central and 

 posterior nervules are four small black spots, two on either side of each. The fringes are brown, broadly 

 spotted with black. Posterior wings are pale brownish and grayish from the middle to the base, with a 

 large black patch at base, two central black bands, and between the latter and the former an oblique demi- 

 line ; a moderate, black marginal band having a bluish one in its centre. The fringes black, spotted with
