In the Dipteres Exotiques the corresponding part of the sys- 

 tem assumes the following shape, about which I have only to ob- 

 serve that in this work Macquart brings in only those genera in 

 which he intended to describe, or at least to mention, exotic 

 species ; the genera Toxoneura, Lucina, Tetanops, Otites, Platy- 

 cephala, etc., although not mentioned in this list, ought, in order 

 to render it complete, to be transferred to it from the former.
