220 THE CANADIAN ENTOMOLOGIST 



wet, and it was getting late, so that I was not discouraged in 

 Ending only a few specimens of Ccenagrion resoliitiim, a little pale 

 blue damsel-fly, which is widely distributed across Canada and 

 already known from Newfoundland. I also took from the creek 

 a single n>mph of a Lesles, apparentU- im'^uiciilatus, and one of 

 ^shna umbrosa, neither of which had been pre\"i()usl\- reported 

 from the island. 



On the following day 1 found a small lake, a mere expansion 

 of a trout stream, the upper end of which was bordered by an 

 open marsh covered with short sedges and similar marsh plants. 

 It looked favourable, but dragonflics were exceedingly few, C. reso- 

 liilum being the only species that could be called common. Enal- 

 lagma calverti, another blue damsel-fly of wide distribution in the 

 north, was taken in small numbers, and I also got two specimens 

 of Somatochlora albicincta, the first of the genus which formed the 

 chief objective of my trip. The most interesting find, however, 

 was another little Coenagrion, of which 1 had taken a pair the 

 preceding year at Nipigon, Ont.. and which proved to be the 

 Agrion interrogatum of Selys, previously known only by a single 

 imperfect fem.ale from Saskatchewan, described in a Belgian 

 journal 40 years ago. (See Can. Ent., XLVII, 1915, pp. 174-181). 

 I searched here for more specimens of this rarity on this and the 

 following day, but succeeded in getting only two more specimens. 

 Along the wood road leading to this lake from the railway a few 

 large dragonflits of the genus ^tshna were occasionally seen, but 

 they were so few that I considered myself lucky to have captured 

 one of them. It was JEshna interriipta E. Walk., another species 

 of transcontinental range. 



This lumlxr road was a good general collecting ground, but 

 collecting was difficult owing to the swarms of black flies (Simulium 

 venustum ? ), "punkies" or sand-flics (Culicoides sp.) mosquitoes 

 and deer-flies iChryscps). I collected a few of the latter which 

 were kindl\- deternined for me by Mr. M. C. Van Duzee, and I 

 was surprised to learn that five species were represented among 

 them, viz , C mcerens Wlk., C. frigiuus O S., C. celer, O. S., C. 

 excilans Wlk., and C. mitis O. S. The only other Tabanid I noticed 

 w as the commion Tcbanus affinis, cf which I took but c ne specimen.
