DASYPOGON. 



Meigen, Illig. Mag., 11, 270, 1803. 



Note. — In the restricted sense, this genus does not occur in N. A. There 

 are a few descriptions coming under this genus in the old sense which 

 have never been elucidated, and perhaps never will be. 

 angustus Macquart, Dipt. Exot., Suppl., iii, 20. — Hayti. 

 bilimbatus Bigot, see Callinicus calcaneus.

rubiginosus Bigot, Annales, 1878, 419 (Scilopogon). — N. A. I put the species 

 here, because Rondani makes Scilopogon identical with his Cheilopogon, 

 which in turn Schiner makes a synonym of Dasypogon in the narrow 

 sense.
