This species is a true Aandotheres, and belongs to the group 

 characterized by the naked periophthalmic space, as A. ginginia- 

 nus, A. tristis and A. melanopterus . It is so distinctly defined as 

 not to be easily confounded with any of the other known species, 

 although in some respects it resembles both A. tristis and A. 

 melanopterus. The only specimen forming part of the ' Magenta^ 

 collections was shot near Thu-Duc, a few miles above Saigon, 

 on the 7th of June, 1866. It is now in the Zoological Museum 

 of Turin.

 of Montevideo, but conspicuous, when flying, on account of the 

 reddish colour on the under surface of the wings. I shot two 

 specimens in the garden of the estancia ' Trinidad ' in January
