conditions for liibernatioii, and even food, if they desired it, in the form 

 of honey, Avas given them, they all died. 



I was at the farm the second week in August last year, 1891, and 

 found many of the moths about the house and outbuildings. In the 

 carriage house, where I had a work table, I could see them running 

 behind the joists and even over my table and under the boxes thereon, 

 their flat bodies enabling them to crawl into very narrow places. This 

 habit of crawling behind and under cover looks as if they were seeking 

 a place to hibernate^ They could be seen behind the blinds on the 

 house, and when these were opened or closed would immediately disap- 

 pear behind them again. 



In December of the same year I again visited the farm, and, determin- 

 ing to see if any of the moths could be found, I searched around the 

 buildings, and behind an old-fashioned lantern I found one of the moths 

 as lively as could be, although the weather was very cold 5 and further 

 search revealed inany of them hidden away behind pieces of boards 

 and old shingles that had been stuck in behind the studding. 'New 

 Year's night, on retiring to our room, Mrs. Southwick discovered one 

 of the moths on the lace curtain, and together we found several of 

 them under the lambrequin over the window, commencing the new year 

 apparently with as much vigor as they had when they emerged from 

 the parsnip stalk. This does not prove they are but one brooded, or 

 that there is only one brood during the year, but it seems to prove 

 that they do hibernate and perhaps may be the same moths I so often 

 saw on the window blinds in August. Yet, I do think it is poor econ- 

 omy to commence to hibernate thus early in the season. Perhaps the 

 moths do go out nights and eke out a precarious living from the flowers 

 until autumn,* but I have collected with lights, and sugared a great 

 deal here, yet have failed to take a single one or see a moth resem- 

 bling it. I 



Discussion of Mr. South wick's paper was deferred, in order to admit 

 of the presentation of a paper on — 



AN EXPERIMENT AGAINST MOSaUITOES. 



By L. O. Howard. 



[This pai>er has beeu already published iu Insect Life, vol. v., pp. 12-14.] 



As Secretary of the Society for Promotion of Agricultural Science, 

 Mr. Howard extended an invitation to the Association to meet with his 

 Society at 2.30 p. m., to listen to entomological papers by. Messrs. Her- 

 bert Osborn and H. E. Weed. 



On motion the invitation was accepted. 



In discussing Mr. Howard's paper Mr. Riley stated that he was glad 

 to note the practical suggestions thrown out by Mr. Howard, in regard 

 to preventing the development of the Mosquito.
