 Grenada, Martinique, and Trinidad, as well as from Mexico, Costa Rica, 

 Nicaragua, Guatemala, Panama, Colombia, Venezuela, Surinam, Brazil, 

 and Peru. I have seen specimens only from Costa Rica, Underwood 

 (Bruner) ; San Mateo del Mar, Tehuantepec, Feb., in lagoons, Sumi- 

 chrast ; and Panama, besides one marked Central America.
