PROPOSAL OF NEW MUSCOID GENERA FOR OLD 



SPECIES. 



BY CHARLES H. T. TOWNSEND, Ph.D. 



Custodian of Muscoid Diptera, U. S. National Museum. 



This paper is intended to establish in as few words as possible 

 certain new genera to contain already erected species which do 

 not properly fall within any genus so far proposed. Definitions 

 and relationship data are already in manuscript and will be 

 published in a forthcoming treatment of muscoid genera of the 

 world. As the differentiating characters are fixed in the holo- 

 types of the species which stand as genotypes of these new 

 genera, and as the full definitions must appear in the final work, 

 their publication in advance of same is not deemed either 

 essential or advisable. 



For convenience of reference, arrangement is alphabetic by 

 genotypes:
