Braconid(B. 



1. Apanteles niilitaris, Walsh. Present in large numbers at Guelpli and 

 apparently general throughout the Province. The cocoons of this species are 

 placed in a loose white mass. These codoon-masses were found in almost every 

 infested area and were often misitaken hy farmers for the eggs of the Army Worm. 

 As many as 28 Braconid larvie were dissected from one Army Worm. 



2. Apanteles, sp. This species, which has not yet been identified, differs 

 from A. militaris in that it has an elongalte compact sulphury coc'oon-mass. It 

 was frequent at Guelph and in various other parts of the Province. 



3. Meteorus communis, Cress. One specimen reared at Guelph. 



Chalcididce. 



Eupteromalus sp. Beared in large numbers at Guelph from Army Worm 

 larvge and pupge. As many as 74 Chalcid pupa? were dissected from one Army 

 Worm pupa. 



In addition to the above insect parasites the Army Worms were attacked 

 by a bacterial disease. 



The identification of Tachinidse parasitic on the Army Worm were made for 

 the writer by Mr. J. D. Tothill, of the Entomological Branch of the Dominion 

 Department of Agriculture. The Hymeai'Oipterous parasit-es listed were deter- 

 mined by Mr. A. B. Gahan, 'of the Bureau of Entomology, U. S. Department 

 of Agriculture. 



The writer is indebted to Mr. J. P. Henderson, of Toronto, for numerous 

 photographs of the outbreak in Brant County, some of which are repi-ioduced. 



The laboratory and insectary work in connection with the study of the 

 Army Worm and parasites was carried 'on by Messrs. A. E. Burrows and E. S. 

 Hartley, student-assistants 'of the Department of Entomology, Ontario Agri- 

 cultural College. 



Prof. Dearness : I saw the worms in Brant County in 1896. 



Mr. Baker : Brant County has a number of large creeks running through- 

 out the county, and large areas of flat lands stretching on each side of these which 

 provide excellent breeding grounds. In many eases the roads would be black with 

 them passing up from the flat areas to the crops. I can hardly credit the report of 

 Prof. Panton that in 1896 when there was a severe outbreak, Brant and Oxford 

 Counties should be free. 



Prof. Caesar : For fear that it should be overlooked, I want to refer to a letter 

 sent me by Prof. Dean of Kansas in connection with the army worm. I have had 

 some correspondence with him on two or three things, and he made some reference 

 to the army worm in that correspondence. He said he had found the new remedy 

 for the grasshoppers so efl'ective in preliminary tests that he recommended to the 

 various counties in his section of Kansas that they set apart a day for army worm 

 control and that they call it " army worm day " just as they had done in previous 

 years for the grasshoppers. Their outbreak was in the spring of the year. As a 

 result of this remedy — the sweetened poison bran — he said that one day's treatment 

 resulted in complete control of the army worm all over the counties that used the 

 remedy. I think that is very valuable. N"o doubt he will publish a paper on that 

 subject, and we shall have fuller details sometime early in the spring. 



The Secretary : Could you let us know how much they used there. 



Prof. Caesar: I cannot give you the details of it. I intended to write to him 

 for I was especially interested in the control of the army worm in corn fields. Those
