48 THE EEPORT OF THE No. 36 



to hearing a number of other papers by our old friends who are not professional 

 entomologists, such as Dr. Eyles' paper this afternoon and Mr, Morris' paper to- 

 morrow. The paper is now open for discussion. 



Mr. Gibson: The study of these Lepidopterous boring larvae such as Mr. 

 Winn has told us about is one which has always given great pleasure to those who 

 are interested in rearing the larvae of our moths. We have not, as yet, found this 

 insect at Ottawa, but now that we know more about the larvae and what they feed 

 upon we hope that we may be able to find the species. The chief boring larva of 

 this family which occurs in the Ottawa district is called the Burdock Borer, 

 Papaipema cataphracta. This is quite a pest, some years attacking soft-stemmed 

 flowering plants, such as dahlia, lily, etc., and in addition, of course, it occurs in 

 burdock and thistle. I am very glad to know that Mr. Winn has donated specimens 

 for the collections here. 



Sir James Grant: Mr. President, I should like to make a few observations. 

 I am happy to inform you that after a very careful survey of the Dominion of 

 Canada, from Victoria on the Pacific to Halifax on the Atlantic, through the 

 whole of Central Canada and Few Ontario, that the work of this Entomological 

 Society has proved of great practical value to Canada in the Department of Public 

 Health. The information that you have given to our people on the part played 

 by the house-fly as carriers of disease has conserved very materially the life of the 

 people of Canada. Those house-flies play, as you know, a very important part in 

 the dissemination of tuberculosis from sputum. There is now, I am happy to 

 inform you, as you will find in my report recently presented to the Canadian 

 Public Health Association at Toronto, a reduction in the past fifteen years of fully 

 twenty-five per cent, in the number of cases of tuberculosis. I have lately gone 

 through whole sections of Central Canada where fifteen years ago the disease was 

 very common, indeed, hundreds of cases in nearly every direction. To-day, with 

 difiiculty, in those sections can you discover a solitary case of tuberculosis, and I 

 am happy to inform this Association that if they continue the good work they have 

 done in the past in the preservation of health by similar measures, and by the 

 destruction of the house-fly, I am confident that the next ten or fifteen years will 

 bring about a reduction of this disease of fully fifty per cent. The head of the 

 Pasteur Institute, Paris, France, has recently announced that throughout the whole 

 of Europe there is now a reduction of fully twenty-five) per cent., and I am very 

 glad, indeed, to have accepted your kind, invitation to attend this meeting to thank 

 you and the members of this Association, for the active part taken in instructing 

 our people, as to the vast importance of the destruction of this house-fly, which is 

 undoubtedly very instrumental in the production of the death rate from tuberculosis. 



Dr. Hewitt: We are very pleased to have Sir James Grant with us and I 

 hope that he will attend as many sessions as he can and hear other papers of 

 interest. 



INSECTS OP STE. ANNE'S, QUE., SEASON OF 1915.
