through the country, and apparently the shore of a now vanished lake) on 

 the one occasion on which I was able to visit it, July 23. 



Cordulegaster diastatops, Selys. One male, June 24, 1889, brook. 



Aeschna cofisfricta, Say. Two males, July 26, 1889; one female, 

 Sept. 2, 1889, may belong here or to the next species. First noticed 

 towards the end of June, and during the remainder of my stay in Pictou 

 was frequently seen everywhere, often far from water, but was difficult to 

 catch. Two of the specimens I sent you were captured in rather unusual 

 ways. One I knocked down with a stick, as I was walking along the 

 road one evening, and I picked him up before he succeeded in picking 

 himself up. The other alighted upon me one morning when I was 

 standing on a ladder untying a clothes line, in such a way that when I 

 lowered my arm (quite unconscious of its presence) it was held securely 

 between my arm and my side. This latter occurrence seemed to me 

 rather indicative of stupidity in the insect, other specimens of which I 

 have known to fly almost in my face when I was not endeavoring to 

 catch them. On the other hand they " dodged " the net with great skill, 

 and on one occasion having found two hovering over a brook, at which I 

 had seen them, when without a net, some hours before, having captured 

 one, I made an unsuccessful sweep at the second, which had flown away 

 a short distance on my scooping in the first, and then returned, when it 

 flew straight away from the brook and did not return, at least to that part, 

 although I waited for some time. 



Aeschna clepsydra, Say. Three males, July 26, 1889. All my three 

 specimens were taken at the deep pond near the Boar's Back, but I think 

 I have also seen them in other localities, and flying about the country 

 like the preceding species, from which it is, when on the wing, to me, 

 indistinguishable at a short distance. (Two of these males are cited in a 

 paper on this species in Ent. News, Vol. V., p. II.) 



Somatochlora Walshii, Scudder. One female, July 23, 1889. I 

 found one female laying her eggs in a little bit of open water, so surrounded 

 and overarched by rushes that her movements were much restricted. 

 (This female, which still remains the only known individual of its sex, has 

 been described by the first of the two authors of the present paper in 

 Trans. Am. Ent. Soc, xvii., p. t,t„ 1890, with a supplementary note in 

 Ent. News, iii., p. 23, 1892.) 



Libelhila quadrimaculata, Linne. One female, July 24, pasture ; two 

 males, one female, July 26, 1889, Abundant in all three localities, but
