5. Simyra argentacea H.S. ab. torosa Guen. 



This seems a distinct form. The forewing is distinctly narrower tlian in 

 argentacea, while the hindwing is pure white. Guen^e says " in both sexes " ; 1 have 

 only c? cT to compare. Hampsou in describing argentacea (Cat. Lep. Phal. B. M. viii. 

 J). 174) calls the hindwing almost pure white in the ? ; this probably refers to the 

 ? of the form ^wosft ; the only ? of ar^e;jtocea in the Tring Museum collection has 

 the hindwings nearly as dark as the Si.
