DASYPOGON. 



MEIGEN, Illig. Mag., ii, 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.

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

 here, because Rondani makes Scilof i ng<>n identical with his Chcilopogon, 

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

 sense.
