104 THE CANADIAN ENTOMOLOGIST. 



post along this route were baited. After the first few applications a crust 

 is formed and only a little refreshening need be applied every evening. 

 On days when the atmosphere is damp the moths will be strongly attracted 

 without any additional applications. The lure should be put on a little 

 before dusk, as the moths start flying quite early in the evening. 



To give a fair idea of what is missed by neglecting the opportunities 

 of late collecting, I have appended a list of the species taken by Mr. 

 Marloff and myself during the last fall and winter. The kinds which 

 occurred in one locality only are followed by the name of the collector. 

 A little discourse, however, on several remarkable evenings experienced, 

 seems appropriate and may lead others to experiment when similar con- 

 ditions of weather prevail. 



On October 4th and 5th we had rather warm and sunny days. 

 Shortly after starting on my luring expedition on the latter date a thunder, 

 storm suddenly came up. A lively shower freshened things up and a 

 drizzling rain continued for about an hour. When the rain commenced I 

 started on the homeward journey, somewhat disappointed at the inter- 

 ference with an evening's recreation. Happily the reverse proved to be 

 the case, for I learned that evening how congenial a damp atmosphere is 

 to the moths. The black clouds caused darkness to settle quickly. 

 Induced by this, and, no doubt, by the moisture in the air, which appears 

 to give a greater range to the aroma of the lure, the moths were noticed to 

 appear so abundantly on the baited trees that I resolved to stay and see 

 the affair through. Nearly one hundred specimens were collected, includ- 

 ing some good species. Of the commoner kinds hundreds might have 

 been taken, but only the desirable varieties were selected. 



Collecting was continued every evening with variable success ; a 

 capture of one or two moths some evenings new to my list making the 

 matter interesting until October 17th. On the following three days very 

 warm weather prevailed and some good material was taken. I collected 

 every evening on these days until about 10.30 p. m., when I was quite 

 tired of travelling up and down the hill. Early on the morning 

 of October 21st a good rain fell and after a cloudy and windy 

 day the temperature was quite cool towards evening. At 5 p. m. 

 rain again set in, accompanied by high wind. Recollecting my experi- 

 ence on the other rainy evening I ventured outdoors about dusk to take 

 a peep at the baited fence posts. The weather was abominable, but on 

 every post were nice newly-emerged examples of Scopelosoma. These
