This species was observed at all points visited from the delta 

 region up, as far as I extended my explorations. Like most, if not 

 all. of the species belonging to this family, its presence in any par- 

 ticular locality depends largely on the ripening of the fruits on which 

 it feeds.

 Orinoco.
