colour without white dusting, and the denser yellow on the secondaries." If this is all, 

 it is evidently a variety of that species with a wrong locality; and, judging by the state 

 of the localities in the Rhopalocera of Kaden's collection, I should say this was highly 

 probable.

I cannot agree with Mr. Grote in thinking Cramer's figure to be intended for this 

 species ; the distinctive apical and inner marginal pale areas of primaries are not marked 

 in that figure, whilst the transverse wavy lines are far more like the S. melancliulica of 

 Grote.
