Specific Character. 



S. alis fuscis ; posticarum disco suprd Jiavescente, maculis 2 fuscis 

 fucato, infrcL albente, margine postico fulvo, maculis 2 atris gut- 

 tisque 7-8 argenteis ornato. 



Wings brown ; posterior above with a yellowish disk and two brown 

 spots, beneath whitish, the hind margin fulvous, with two 

 black spots and 7-8 silver dots. 



Without being ornamented by rich or vivid colouring, 

 this is, nevertheless, one of the most chastely beautiful little 

 butterflies found in Brazil. I met with it very plentifully in 

 a small wood not far distant from Cashoera, on the western 

 extremity of St. Salvador's bay : to this particular spot it 

 seemed confined, for I never saw a single specimen in any 

 other part of Brazil. 



No colouring can imitate the richness of the silvery spots 

 on the under wings, which appear embossed, or as if solid 

 drops of silver had fallen on the insect when it first emerged 

 into life. The two sexes are perfectly similar. 



The insects of this genus are usually brown, with dark or 

 paler shadings, and eye-like spots on their upper or under 

 wings. They principally inhabit the woods of tropical regions, 

 and the hedge sides and lanes of European countries ; this 

 circumstance probably induced Latreille to change their name 

 from llipparchia (Fabricius) to Sati/riis; which, although an 

 innovation on the rules of nomenclature, may in this instance 

 be allowed.
