68 THE REPORT OF THE No. 19 



2. Calojyteryw aequahilis, Say. In 1902 I saw four or five of this species 

 along the river, but captured only one, a male. In 1903 nine were seen. 

 Among Prof. Macoun's specimens there are two fresh males dated July 6th 

 and 26th, 1900. They are probably much commoner at that season.

 into Ragged Lake. They were associated with Ischnura verticalis and ten- 

 eral examples of SympetruTn vicinum.

13. OphiogoTnphus rupi7is^ilensis, Walsh. This fine green species was 

 quite common on the river, flying over the shallower rapids and frequently 

 settling on the exposed pebbles. 



14. Hagenius hrevistyhts, Selj^s. Four males, all somewhat worn, were 

 captured along the river. Two were taken by Mr. Hahn with one sweep of 

 the net while flying over the water, August 22, 1903. Another was taken 

 while resting in a path in the woods close to the river, August 20, 1903. In 

 addition to these two nymph exuviae were found on the rocks on the shore of 

 Oxtongue Lake, August 10, 1903. 



15. Lanthus alhistylus (Selys). This dainty little Gomphine was fairly 

 numerous locally over rapids. They were difficult to approach and only one 

 male was taken (August 10, 1903). 



16. Gomphus brevis, Hagen. A worn female was captured on the river 

 at Whisky Falls, August 20, 1903, and a few minutes afterwards a male, also 

 worn, was taken at nearly the same spot. Two nymph skins were found on 

 the logs of a timber slide at the upper end of Ragged Lake. 



17. GoTnjjhus exilis, Selys. This nymph skin was found on the timber 

 slide at Ragged Lake. Several others were found by Mr. Hahn on a log hut 

 at the edge of Smoke Lake. 



18. Gomphus Scudderi, Selys. This striking species was common on 

 certain parts of the river, usually where there was a considerable current, 

 but where the water was fairly deep. It was not so often seen over the swift 

 rapids. They ,were usually moving along slowly with swiftly vibrating 

 wings, every now and then making a dash to another spot. They would
