DIPTERA. 7 



ander, July 17, 1913. From August 17 to 20, 1905, Mr. Frank M. 

 Jones collected a number of interesting species at Katahdin Iron 

 Works. On September 7, 1907, Dr. Cushman made a collection 

 at Chamberlain Lake. 



5. The Rangeley Lakes area. — This area includes Franklin and 

 the northern portion of Oxford Counties. From July 1 to 4, 

 1922, I collected at Oquossoc, along the stream flowing out of 

 Rangeley Lake. On J^ly 6, 1916, Mr. C. A. Frost collected at 

 Parmachene Lake. From July 18 to 20, 1916, Dr. C. L. Metcalf 

 collected on Saddleback Mt. In June, 1922, Mr. H. C. Dunham 

 collected at Upper Dam, and on August 24, 1922, Mr. S. N. F. 

 Sanford made a small collection at Rangeley. 



6. The Lower Penobscot area. — This area embraces the lower 

 part of the Penobscot River valley. Orono is the center of 

 entomological activity in Maine. Dr. Edith M. Patch, Ento- 

 mologist of the Maine Agricultural Experiment Station, has built 

 up a valuable collection, which I have been privileged to examine. 

 Dr. A. O. Johannsen while at Orono wrote "The Fungus Gnats of 

 North America," and Dr. C. L. Metcalf the "Syrphidae of 

 Maine." Dr. C. P. Alexander has worked on the Tipulidae, 

 describing many new species from the State. Mr. E. F. Hitchings, 

 has a large collection which I have studied. Dr. H. M. Parshley 

 and Mr. A. P. Morse have also collected Diptera at Orono. Dr. 

 G. de N. Hough collected at Eddington, June 25 to July 5, and 

 the writer at Hampden, July 10, 1907. 



7. The Washington County area. — This includes the entire 

 County. From July 10 to 27, 1909, the writer collected at the 

 following places: Calais (above Milltown) July 10; Princeton, on 

 the Indian Reservation, July 12; Eastport, west of the town and 

 in the vicinity of Shackford's Head, July 14 to 16; Machias, along 

 the Machias River both above and below the town, July 17 to 27. 

 Dr. Cushman while botanizing on Mistake Island, August 9, and 

 at Roque Bluff, August 10 and 11, 1907, collected some interesting 

 flies. Mr. A. P. Morse also collected at the latter place, August 



13, 1913. 



8. The Mount Desert area. — This area is restricted to Mount 

 Desert Island. The work of making a faunal list of the insects 

 of Mount Desert has resulted in recording over 1000 species of 

 Diptera from the island. Work was begun in 1918, and from 

 July 10 to 18 the writer collected at Southwest Harbor from 

 Echo Lake and Great Pond to Manset. In 1919, the work was 

 confined to Bar Harbor and vicinity (including Mt. Cadillac) 

 from July 16 to 30. In 1920, collecting was done at both ends 

 of the island, and on the salt marshes at the "Narrows" from 

 August 10 to 24; this was repeated in 1921, from June 7 to 22, 

 and again in 1922, from June 16 to 28 and from September 6 to 



14. In 1923, collections were made at Bar Harbor, Salisbury
