posterior cell of the wing is very narrow apically but not closed ; the 

 second vein exceeds the level of tp by the length of tp; postvertical 

 bristles are lacking; two well-developed anterior f rentals are present 

 definitely within the tomentose mesofrontal area; the posterior 

 f rontals are about opposite the anterior ocellus ; and the bristles of the 

 mesonotum include 1 dc^ 2 sa, and 2 strong ntfl. The arista is dis- 

 tinctly and abundantly short plumose. 



Remarks. — I take pleasure in naming this genus in honor of the 

 discoverer of its type species, Dr. H. K. Townes.
