FURTHER NOTES ON THE OCCURRENCE OF HEPIALUS 

 THULE, STRECKER, AT MONTREAL.* 



I'bY H. H. LVMAN, M.A., MONTREAL. 



In 1893 I '■^^d a paper on the occurrence of Hepialus Thule, 

 Strecker, at Montreal, before the Entomological Club of the American 

 Association for the Advancement of Science at Madison, Wis., which was 

 afterwards published in the December number of the Canadian Ento- 

 mologist of that year. That paper embraced everything that was known 

 of this species up to that date, but since then various facts of interest in 

 connection with it have come to light. 



From the above date, I hunted for it in its then only known locality 

 every year when at home in its season, but absolutely without success up to 

 July, 1 90 1 , when, on the 1 1 th of that month, after a hard bicycle ride out on 

 the upper Lachine road, I arrived at the spot on the brow of the old sea 

 terrace where others had seen it, in time to see one swinging back and 

 forth in its peculiar oscillating flight. Hurriedly mounting my net I made 

 a stroke at it, but the tall growth of grass and weeds masked the edge of 

 the bank, and I missed my footing and came down sprawling, the coveted 

 prize, as usual, dropping into the grass. I was up again at once, and 

 when the moth again rose in flight, but this time straight away to escape, 

 I made a more accurate stroke and secured it, but that ended the sport, 

 and no other was seen either on that evening or subsequently. 



In 1902 it occurred to me that there was no reason why the species 

 should not be found at Montreal Junction, situated on the brow of the 

 same old sea terrace, a few miles further to the south-west, at a point 

 where it began to trend to the north-west, and as it was much easier to go 

 out the ten minutes' run by railway than to ride out to the other point on 

 a bicycle, I suggested to Mr. Winn our making a trip out there on the 

 evening of July i6th. We reached that point a few minutes before 8 

 o'clock, and agreed to separate, as we could thereby cover more ground. 

 Mr. Winn went to the south-east, while I went more to the north-west to a 

 pasture on the brow of the terrace just beyond the house of a cousin. 

 There was a steep gully, probably caused by a landslide many years ago, 

 running down to the lower level covered by bushes and scrub of various 

 kinds, and in this gully several large trees had grown up. I had only just 

 got to the place when I saw a number, apparently half-a-dozen or more, 

 swinging back and forth in the air, as though participating in a dance,
