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.
