This species is very widely spread, and its synonymy almost 

 certainly not yet known. 



So far as can be at present determined Porath's name has the prior- 

 ity ; but there is little doubt, in my opinion, that this name will have 

 ultimately to give way to some other at present not yet identified. This 

 species is very commonly met with in the Oriental Region. Porath has 

 recorded it from Sumatra, Java, and Borneo. The British Museum has 

 examples', from Assam, Burma, Cambodia, China, Cochin-China, Singa- 

 pore, the Seychelles, and from Dominica in the W, Indies. I have 

 carefully compared the type of dominicfS with examples from many loca- 

 lities in. the old world and can find for it no differential characters.
