dent, Mr. E. I.. Peirson, Jr., collected on occasional afternoons from April until early June, and his material was determined through the kindness of Dr. P. P. Calvert. Mr. Peirson published in the Proceeding of this Museum (Vol. I, p. 41, 1915) a list of twelve species, a few of which had been collected preceding his work and which had been determined by Mr. C. W. Johnson. Mr. Peirson published this list largely because he had secured the second cap- ture of Williamsonia lintneri in New England (see also Ent. News, 26, p. 238, 1915), a species never before recorded from these states. During the past summer, because of continued residence in Concord, I have had the opportunity to collect almost daily, and have visited practically all the ponds and the river valleys, with the result that I am now able to publish a considerable list of species. No doubt further collecting in April and May will add many species in the Gomphinse. Throughout the summer I had the help of my daughter, Miss Susan A. Howe, and in my deter- minations I have had the continual aid of Mr. Edward B. Will- iamson, and also occasionally that of Mr. Richard A. Muttkowski and Dr. E. M. Walker. To these gentlemen I extend my sincere thanks.
In the present list I have made my comparisons of distribution with Dr. Calvert's List of the Odonata of New England (Occas. Papers Bost. Soc. Nat. Hist., 7, 1915).
