 with narrow lateral and basal pale yellow stripes. Abdomen black, with second and fourth

 Fore wings nearly opaque, the usual vitreous spaces being clothed with scales, purplish brown or 

 golden yellow on the outer part and along the inner margin ; underside more or less golden yellow, 

 sometimes entirely of this color. Hind wings transparent, outer margin purplish or more or less 

 golden yellow with the fringes darker. Underside similar to the above. 



Expanse : 15-17 mm.

Type : One female. Coll. Hy. Edwards, Am. Mus. Nat. Hist. 



The opaque fore wings and two yellow bands on the abdomen will serve to 

 distinguish this species from its nearest ally, S. rutilans. The male and earlier 

 stages are not known.
