NOTES ON DIPTERA 



In Can. Entom., 1911, p. 130, I described a new species of 

 Laphria as L. dispar; I find that the name is preoccupied and 

 would replace it by Laphria disparella n.n. 



In the fall of 1912 I took two rare Tachinids, Euceromyia robert- 

 soni Towns, at Falls Church, September 14, and Trichopoda plum- 

 ipes Fabr. at Great Falls, October 3. The Euceromyia was un- 

 known to Coquillett, and the genus not in his table.
