258 THE CANADIAN ENTOMOLOGIST 



in the shelter of a bush and waited for a chance to strike with 

 the net from behind. In a few minutes I had netted a male of 

 Cordidia shurtleffi Scudd, and soon afterwards I had several more. 

 This is a beautiful insect with a bronze-green body and brilliant 

 green eyes. It is a ver\' characteristic northern species, C(jmmon 

 across C anada to Vancouver Island. I also took here a fine male 

 of Sotmitochloni ciiv^ulala Selys, the tirst I had ever seen. With 

 its dark bronze body, with white transverse abdominal lines and 

 bright green eyes, it looks very like a large form of S. albicincta, 

 but it is much less common. It was the last dragonfly I captured 

 in Newfoundland, as I was now- obliged to return to the hotel, 

 and. on the same day, to start on my homeward journey. 



1 ha\ e made several allusions to the scarcity of dragonHies 

 in the \ icinit\' of Spruce Brook. How are we to account ior such 

 a scarcity under apparently faxourable conditions.-' Of course, 

 there are good and bad years for dragontiies, as for everything 

 else, bui I am inclined to believe that some other cause than the 

 usual seasonal ones was operating here. It is worth>' of note that 

 all the lakes and ponds where I collected were connected with 

 trout streams, and it is well known that brook trout feed upon 

 dragon-fly larva\ Beaver Pond, particularh', teems with trout, 

 and is a favourite place for trout-fishing. I saw numbers of finger- 

 lings at the spot when I collected most of m\- dragonHies. It is 

 therefore a possibilit>' that the scarcity of dargonHies in this locality 

 was due, in part at least, to the abundance of brook trout. 



There appeared to be a similar scarcity of other acjuatic 

 insects, very few caddis-flies, e.g., ha\ing been obserxed. The 

 little dark Mystacides sepulchralis was rather common about 

 Beaver Pond, but the only other species noted were a few speci- 

 mens of a Limnephilid, not yet determined, and a single example 

 of the large Glyphotcelius hoslilis, found in a spider's web. Like 

 most of the dragonflies noted, this species ranges wideK- across 

 the continent in the north. 



Diptera and Hymenoptera seemed to be fairly plentiful at 

 Spruce Brook, in individuals if not in species, though little efifort 

 was made to collect them. One of the best places to obtain them 

 was a glass-covered passage connecting two parts of the Log
