1915] Britton — Macrosargus cuprarius Linn. 31 



America and was not represented in any of the older collections, I was inclined to 

 consider it a recent introduction, but this theory has been somewhat shaken since 

 collecting it in considerable numbers at Niagara Falls, N. Y., June 24-28, 1901, 

 and receiving specimens the same year from Mr. G. Chagnon who collected them 

 at Rigaud, Quebec, July 27. In 1903 I came to Boston and was surprised to find 

 it quite common in the vicinity (Blue Hill, May 30, and Auburndale, July 19- 

 Aug. 13.). Since then I have collected it at the following localities: — Hyannis Port, 

 July 4, 1904; Calais, Me., July 10, 1909; Middletown, Conn., June 17, 1909 and 

 Bretton Woods, N. H., June 27, 1913; near Newport, R. I., June 5, 1914. Recently 

 I have received specimens from Brother Germain, taken at Ottawa, Canada.
