One ? from the Felder Collection, without locality-label, but collected by Lindig,

One $ from Maraval, Trinidad, July 1891. 



In markings and colouring very much like (S. occultata from Sao I'aulu, but the 

 shape of wings entirely different; the apex of forewings is bluntly subfalcate, and 

 the hindmargin without any excavation; the hindwings with hindmargin much less 

 produced, the tooth quite blunt.
