On the geographic range and distribution of the 

 genus Trichopoda. 



By C. H. T. Townsend, Las Cruces, N. M. 



The Tachinid genus Trichopoda is, so far as known, exclusively 

 American. It is not necessarily tropical in distribution, though 

 a considerable number of species have been reported from the 

 tropical portions of South America. It is, however, peculiarly 

 limited in range to certain topographical conditions, being found 

 usually only at low elevations, down near the sea-level. It seems 

 to attain its maximum development in the more southerly, but 

 temperate latitudes of the United States, near the Atlantic sea- 

 coast. It is represented on the Pacific coast but by a single spe- 

 cies, T. pennipes Fab. , which is found from New England to the 

 Argentine Republic, in favorable localities situated but little above 

 sea-level. It is notable, also, that this species is the smallest one 

 of the genus. 



So far as my personal observation in collecting goes, I can give 

 the following notes on the range of the genus: I have never found 

 Trichopoda in other than one locality, the District of Columbia 

 on the Virginia side of the Potomac. There it is well repre- 

 sented in both number of species and individuals. I do not re-
