By R. Heber Howe, Jr., 

 Thoreau Museum of Natural History, Concord, Mass. 



The following list of Odonata includes material collected last 

 summer at Chatham, and also that taken on various excursions to 

 the surrounding towns. Mr. C. W. Johnson had collected a few 

 species at Eastham of which I make mention, and other species 

 have been recorded from Provincetown, Cotuit, Hyannisport, 

 Woods Hole, Martha's Vineyard, the Elizabeth Islands, beside 

 those listed by the author from Nantucket (May, 1919, report 

 Maria Mitchell Association), and from Wareham (Psyche 26: 

 June, 1919) , Specimens of all recorded material are in the author's 

 collection.
