All my specimens of this extremely rare and fine species 

 were collected in Uppei Amazon, by Buckley. 



I should not be surprised that D. iris and hesperiis, should 

 turn out to be the same species, all the adult male specimens 

 being those with the upper and underside green, and all the 

 others with chestnut on back and abdomen, female or young.
