females especially looked somewhat different from meigenii, and on 

 comparing them with specimens of E. arbustorum from Europe in 

 my collection they were found to belong to the latter species. I then 

 looked over my series of meigenii very carefully, with the result that 

 a number of arhiistoriim were discovered, some of them dating as far 

 back as 1906. 



A few days later the above locality was revisited, when I col- 

 lected about fifty specimens, males and females about equally repre- 

 sented. After this, for a time, I took all the specimens of both 

 meigenii and arbustorum that came in my way, with the result that 

 the latter species soon became much better represented in my col- 

 lection than the former. 



Also, on looking through the collections of the American Museum 

 of Natural History, the Museum of the Brooklyn Institute of Arts 

 and Sciences, the Staten Island Museum and the Cornell University 

 collection, as well as a number of private collections, I found nu- 

 merous specimens of arbustorum masquerading as meigenii. 



A short time ago Mr. Frederick Knabof the National Museum- 

 at Washington wrote to me in regard to the occurrence of E. ar- 

 bustorum in America, as he had found a specimen so labelled in 

 Coquillett's writing in the collections of that museum. This re- 

 minded me that it was time some mention of the occurrence of this 

 species in America should be made in print. 



From my own observations and from the personal study of ma- 

 terial in my own and other collections I can now state that E. ar- 

 bustorum is widely distributed over eastern North America, as far 

 west as Ohio, south to Virginia and north to Labrador. My own 

 collection consists of more than a hundred specimens covering points 

 within this range and I have examined as many more in other col- 

 lections. 



On corresponding with other dipterologists, I find that all of them 

 who have collections from the region mentioned confess to having 

 specimens of arbustorum confused with meigenii. Prof. J. S. Hine, 

 of the Ohio State University, states that he has specimens from 

 northern Ohio. Mr. Chas. W. Johnson, Director of the Museum of 

 the Boston Society of Natural History informs me that he has speci- 

 mens from all the New England states except Vermont and that this 

 species is much more common than meigenii. Mr. E. T. Cresson, Jr.,
