12 FAUNA OF NEW ENGLAND. 



to 16, 1915, the writer collected at Great Barrington, in the valley 

 south and on the mountain east of the town. On July 24, 1917, 

 I collected near the New Lenox and along the road leading to the 

 top of October Mt. Mr. J. W. Beecroft has collected at Cheshire 

 and Great Barrington, Mr. C. A. Frost has collected at Monterey 

 and Professor John Barlow at Peru. 



24. The Connecticut River Valley area. — The part of the Con- 

 necticut valley within the confines of Massachusetts is especially 

 interesting, for its diversified condition presents local environ- 

 ments favorable to both northern and southern species. A great 

 deal of entomological work has been done here. Springfield has 

 for years been the home and collecting ground of Dr. George 

 Dimmock. In July, 1905 (13 to 15), I had the pleasure of col- 

 lecting with him near his home and on Mt. Tom. Amherst, the 

 seat of the State Agricultural College, with its large collection 

 and corps of workers is a "beehive" of entomological activities. 

 To Dr. H. T. Fernald I am indebted for the privilege of studying 

 the college collection and for other assistance. Dr. C. P. Alex- 

 ander has made a special study of the Tipulidae of the valley. 

 In company with Drs. Crampton and Alexander, I collected at 

 Sunderland and Whately Glen, May 29 and 30, 1923. Mr. 

 Stanley W. Bromley has also collected many Diptera in this 

 area. Mr. Owen Bryant collected at Westfield, July 10, 1905. 

 Mr. H. E. Smith collected a number of interesting species at 

 West Springfield; Mr. F. E. Zeissig has collected at Ware and 

 the writer at Williamsburg (August 7, 1911). Miss Fannie A. 

 Stebbins, in her work on the "Insect Galls of Springfield and 

 Vicinity," gives many records for the Cecidomyiidae. 



25. The Worcester County area. — This area should really be 

 confined to the more elevated portions of the County, but it is 

 difficult to draw the line. The late Dr. F. W. Russell collected 

 a number of species at Winchendon. Mr. R. T. Webber collected 

 at Lunenburg, Miss Susan Minns at Princeton and Mrs. Ella L. 

 Horr at Worcester. The writer collected on Mt. Wachusett, 

 May 30, 1914, and at Rutland, June 5 and July 9, 1915; May 

 31, July 31 and September 20, 1916. Mr. Stanley W- Bromley 

 has collected many interesting species at Southbridge. The 

 writer has also collected there July 8 and 16, August 27 and Sep- 

 tember 3, 1912-15. Dr. L. H. Taylor has collected at Petersham, 

 August, 1920. The late Millet T. Thompson's collection of in- 

 sect galls is now the Society's, most of the material having been 

 obtained in the vicinity of Worcester. 



26. The Essex County area. — In this area I am including the 

 valley of the Merrimack as far as Tyngsboro, where Mr. H. C. 

 Fall has captured a number of interesting flies. Beverly was 

 the home of Edward Burgess, who was interested in Diptera. A 

 number of species have been recorded from his collection, which
