THE CANADIAN ENTOMOLOGIST. 319 



about the shallow pond I never succeeded in catching a single specimen. 

 They " dodged " every time. I captured one which had alighted on a 

 stump near the boggy brook, but as I was taking it out of the net it 

 grabbed my finger savagely, whereat I was so taken aback that I let him 

 shp from my fingers, when he, of course, lost no time in " making himself 

 scarce." After this I made many vain attempts to capture specimens of 

 this kind, but got none. On visiting the pond near the Boar's Back, 

 however, I succeeded in capturing three, stealing up and sweeping them 

 in suddenly when they were close under the steep bank at one side of the 

 pond. Five males, one female, 1890— pond half a mile east of Boar's 

 Back, July 12. 



Leticorhinia proxima, Calvert. Two males, July 26, 1889. I saw 

 none, to my knowledge, away from the pond by the Boar's Back, where 

 the two specimens I* sent you where taken. (These were two of the 

 types of the original description of this species in Trans. Am. Ent. Soc, 

 xvii., p. 38, 1890.) One male. 1890. 



Leucorhiiiia hudsotiica, Seiys. One male, one female, June 25, 1889; 

 I never saw any but the two specimens I sent you, which were taken in 

 locality No. 2. (These two were the types of what was too hastily 

 baptized Leticorhinia Hageiii, n., sp., with the first of us as sponsor, in 

 Trans.> Am. Ent. Soc, xvii., p. ^d, Jan., 1890, and as promptly buried in 

 Etit. News, i., p. 73, May, 1890. If there were any hopes of a revivifi- 

 cation, it is only necessary to add that in July, 1890, on the occasion of a 

 visit to Cambridge, Dr. Hagen and myself compared this couple with 

 types of Z. hudsonica in the Museum of Comparative Zoology, and satisfied 

 ourselves that they were specifically identical.) 



Leucorhinia intacta, Hagen. Six males, July 12, J890 — pond half a 

 mile east of Boar's Back. 



Diplax rubiaindula. Say. June 25, July 24, Aug. 21, 1889. 



Diplax obtrtisa, Hagen. July 24, 1889. 



(Mr. Sheraton's notes refer to these two very similar species together.) 

 No. 7 (specimens of B. rubicundida taken June 25) was abundant in all 

 three of the places in which most of my collecting was done, but especially 

 so about the boggy brook, where I first saw it. They were easily caught. 

 They had a curious habit of rising suddenly from the weeds about the 

 brook, flying along a short distance not far off the ground, and then 

 alighting upon it like a locust. The likeness to the latter insect in so 

 doing was much increased by their size, colour, and by their flight, which
