Argyramoeba duvaucelii, Macq. 



Redescription. 



This species was first described under Anthrax, and I retained 

 it in this genus in my recent paper ; but a number of specimens 

 recently obtained by the Indian Museum afford me the oppor- 

 tunity of recognising it as a true Argyramoeba, the pencil of hairs 

 at the tip of the antennal style being conspicuous, whilst the 

 anterior branch of the third longitudinal vein shows a strong ten- 

 dency to appendiculation , although it is actually appendiculated in 

 one specimen only, in which, moreover, an additional veinlet (in one 

 wing only) produces the particular submarginal cell characteristic 

 of Hyperalonia. As this species was very insufficiently described 

 by its author, I venture to append a redescription.
