NOTES ON NOVA SCOTIAN DRAGONFLIES. 



BY PHILIP P. CALVERT, PHILADELPHIA. PA., AND WILLIAM SHERATON, 



TORONTO. 



(In 18S9 and 1890, Mr. William Sheraton, of Wycliffe College, Toronto, 

 collected some Odonata at Pictou, Nova Scotia, for me. At the end of 

 the collecting season of 1889, he sent me a letter containing his field notes 

 on the specimens captured. These observations are so interesting, in my 

 opinion, that any publication in which they appear ought also to bear Mr. 

 Sheraton's name as joint author. He has kindly acceded to my wish in 

 this respect, although modestly protesting that his part has " been only 

 such as any child could have done." All notes in the present paper 

 concerning localities, habits and dates are to be credited to Mr. Sheraton, 

 while I am responsible for the determinations and the few bibliographical 

 notes. With the exception of Aeschna consiricta, none of the species 

 mentioned below had been recorded from Nova Scotia previous to Mr. 

 Sheraton's taking them, although I have since cited the locality, for some 

 of the species, in various papers — P. P. C.) 



The dragonflies which I obtained in Pictou were, with few exceptions, 

 from three localities, (i) a smill, shallow, weedy pond in an open field — 

 "Simpson's pond"; (2) a small, boggy brook, full of rushes, etc., in a 

 back pasture (marked on envelopes, " Brook north of Priest's Barn," or 

 " Mr. Simpson's back pasture ") ; (3) a much larger and deeper pond, 

 surrounded on every side but one with a thick second growth of spruce 

 (marked " Pond on Back Road near the ' Boar's Back "). Most of the 

 kinds I got were found in all three localities, but they all appeared to 

 have some preference in the matter. 



Lestes tmguicuiata, Hagen. Pasture, Aug. 21, 1889. 



Lestes tcncata, Kirby (hamattiy'SitXy^, 1862.) June 19, 1889, common 

 about Simpson's Pond and the boggy brook, and I think were also found 

 at the larger pond, although I have not recorded the capture of any 

 specimens there. July 23, 1889, the pasture; also 1890. 



Enallagma ebrium, Hagen. Exceedingly abundant from the begin- 

 ning (June 19, 1889) to the end of the season in the first locality, and 

 quite abundant also about the boggy brook, particularly in the earlier 

 part of the summer, and at points where it broadened into small pools 

 with more or less open water. They were also abundant at the larger 

 pond by the Boar's Back (a great ridge of gravel, running for some miles
