DIPTERA. 15 



August 27, 1921; and the writer August 8, 1918. Dr. Allen 

 also collected on Tuckernuck, July 21, 1910; and Dr. Cushman, 

 August 6, 1909. Mr. W. S. Brooks collected a number of Dip- 

 tera on Muskeget, July 7, 1916 and July, 1924. 



31. The Martha's Vineyard area. — This should comprise all 

 of Duke's County but work has been confined to Martha's 

 Vineyard, although an exhaustive study of the insect fauna is 

 yet to be made. Dr. J. A. Cushman, while collecting fossils at 

 Gay Head in 1904 and botanizing in 1911, collected a number of 

 insects at North Tisbury, July 20-21, and at Chilmark, August 

 14-17. The writer collected at Edgartown, June 28 and 29, 1910, 

 August 22 and 23, 1912, and at Oak Bluff, June 13, 1917. Mr. 

 A. P. Morse has collected at West Chop, July 4 and August 5, 

 1893. 



32. The Bristol County area. — This includes the entire County, 

 but collecting has been mostly confined to the southern half, 

 which yields many austral species. Dr. Gary de N. Hough made 

 a most interesting collection of Diptera at New Bedford and 

 Horse Neck Beach between 1894 and 1900, and published a 

 number of valuable papers. Mr. N. S. Easton has collected a 

 number of species in the vicinity of Fall River. In company 

 with Mr. Easton the writer has collected at Horse Neck Beach, 

 July 30; Westport Factory, July 31, 1913; and near Fall River, 

 July 12, 1916. Dr. J. A. Cushman and Mr. S. N. F. Sanford 

 have also collected at Fall River and Mr. H. M. Holt at Goose- 

 berry Neck. 



RHODE ISLAND. 



33. The Rhode Island area. — For convenience it seems best to 

 include the entire State, although east of the Sakonnet River 

 would more naturally belong to the Bristol County area. I 

 have studied the large collection made by Professor John Barlow 

 at Kingston. The writer has collected at Buttonwoods, July 25, 

 1911, and June 12-22, 1912; Washington, June 19, and Apponaug, 

 June 21, 1912; Tiverton, July 31, 1913, and July 12, 1916; New- 

 port, June 5; and Wickford, June 9, 1914. Newport is the type 

 locality for several species collected by Baron Osten Sacken. 

 Through the kindness of Mr. Howard L. Clark I had an oppor- 

 tunity of collecting at Bristol, June 20, 21, 1918. 



CONNECTICUT. 



34. The Litchfield area. — This area includes the upper portion 

 of Litchfield County, northward of the towns of Litchfield and 

 Kent, having a general elevation of over a thousand feet. Dr. 

 W. M. Wheeler has collected a large number of interesting species 

 at Colebrook. Mr. K. F. Chamberlain has collected some 

 Diptera at Cornwall, Mr. L. B. Woodruff at Litchfield and Mr. 

 A. P. Morse a few at Kent. Some species have also been received
