36 THE EEPORT OF THE No. 36 



radislie.5, onions, beans, etc. A few 3'ears ago I found, when studying tlie life- 

 history of Musca domestica, that the flies of the root-maggot (Anthomyia radicum, 

 Meigen), were especially fond of laying their eggs on horse manure in which the 

 larvae were reared. This fact may account frequently for the presence of root 

 maggots on crops, as it has been found that fields heavily manured suffer more 

 from the attacks of root maggots than those on which there is less manure or which 

 have been manured some length of time. Such facts as these have to be borne in 

 mind in cultivating infested areas. 



These few cases of the economy of certain allied insects will illustrate to yon 

 the benefits and injuries that are the result of different modes of life of insects 

 somewhat closely allied and show how the knowledge gained from a careful study 

 of the life-histories and habits of life or bionomics can be applied to further the 

 welfare of man. 



At the close of Dr. Hewitt's lecture, which was illustrated by a number of 

 beautiful lantern slides of the life stages of various species of flies and of their 

 structural and anatomical details (Plate F, page 141), a hearty vote of thanks was 

 ^iven him. President Creelman, in proposing the vote, and Professor McCready, in 

 seconding it, spoke in high terms of the excellence of the address and the gratifi- 

 cation that all felt in the appointment of so well qualified a successor to the late 

 Dr. Fletcher. 



The chairman referred to the measures that had been put in operation for 

 reducing the number of disease-bearing flies in the city of New York, and the 

 encouraging diminution in the percentage of cases of sickness and death during 

 the later months of summer, especially amongst children. The meeting wa=^ 

 brought to a close with a musical performance by the orchestra and the singing of 

 '' God Save the King." 



SECOND DAY'S SESSION— FRIDAY, NOVEMBER 5TH, 1909. 



The President, Mr. Tennyson D. Jarvis, took the chair at 9.30 a.m., in the 

 Biological lecture-room of the Ontario Agricultiiral College. There was a good 

 attendance both morning and afternoon, including many of the students as v/ell 

 as members of the Society. The first order of the day was the reading of the 

 reports of the Council, the Branches at Montreal and Toronto, and of tlie different 

 officers of the Society. The Montreal Branch was represented by Mr. A. P. Winn, 

 and Toronto by Mr. J. B. Williams. The report of the Delegate to the Royal 

 Society was read by Mr. A. Gibson, of Ottawa. This was followed by the election 

 of officers for the ensuing year, 1909-1910 (see page 6). 



EEPORT OF THE COUNCIL. 



The Council of the Entomological Society of Ontario begs to present the 

 report for the year 1908-09. 



The forty-fifth annual meeting of the Society was held at the Ontario Agri- 

 cultural College, Guelph, on the 5th and 6th of November, 1908. There was a
