ENTOMOI,OGICAL SOCIETY OF ONTARIO. 101> 



Other insects that are working on the foliage and in the stems of our plants we have 

 in great numbers, but enough has been said to give an idea of some of the work we try- 

 to accomplish. Could we have sufficient force to do the work at the proper time there 

 seems to be no reason why our parks could not be kept in the best condition; but with a 

 force of but two men, with the entomologist, the wonder is that even a respectable show- 

 ing can be made and the vegetation kept in as good condition as we now find it. 



Mr. Howard said that he was very much interested in Mr. Southwick's account of 

 the use of water as an insecticide and referred to some experiments in the same line which 

 he had conducted, in which he showed a strong stream of water to be an effective agent 

 against the rose slug and certain other insects. 



Some discussion followed on the nature of the work and the probable species of the 

 sap worm described by Mr. Southwick, which was thought by Mr. Lintner to be probably 

 a species of Sciara. 



Mr. Southwick followed with a second paper on the Wood Leopard Moth in the 

 parks of New York, giving an historical account of the insect, its present status, the 

 nature of the injury, the plants affected, and the means he had adopted to exterminate 

 the pest. He stated that this is a most difficult insect to control, and could only be reach- 

 ed by cutting oil' the aftected limb. In the case of rare trees, he had adopted the plan of 

 putting a little bisulphide of carbon in the larval burrow with an oil can, closing the 

 entrance with putty, which had proved an effective remedy. 



The paper was discussed by Messrs. Smith, Howard and others. 



In the absence of Pruf. F. H. Snow, of Lawrence, Kansas, his paper was read by 

 Mr. Victor H. Lowe, This communication, entitled " Work in Economic Entomology 

 at the University of Kansas for the season of 1894," related particularly to the succesafu? 

 work with the chinch bug disease [Sporotrichtirn (ilob>dif<iruin), and a new alfalfa and 

 wheat pest, which proved, on rearing, to be Agrotis introferanx, Grote. 



Mr. Smith reported that the same noctuid had been found by Mr. Gillette to occur 

 very abundantly the present year in Colorado, and JNIr. Howard referred to the occurrence 

 of the moth in enormous numbers in Nebraska. 



Messrs. Ash mead, Lintner and Hopkins were apppointed by the President a com- 

 mittee lo nominate officers for the ensuing year. 



MORNING SESSION— AUGUST 15th, 1894, 



Mr. Hopkins presented notes on some discoveries and observations of the year in 

 West Virginia. The paper dealt chiefly with wood-working insects, but also covered 

 various garden pests, such as the potato-scab gnat, the melon plant-louse, etc. The 

 paper was discussed at some length by Mr. Smith, Dr. Lintner, Mr. Kaine, and others. 



The President read a letter from Mr. Webster, stating that he was unable to be 

 present on account of b*-ing actively engaged in stamping out an attack of Fidia larvjv 

 on grape roots, by the use of bisulphide of carbon. 



Mr. Howard read a paper on the eastern occurrences of the San Jose scale^ in which 

 he briefly reviewed the history of the insect in the United States and showed that as a 

 result of investigations during the winter of 1893 4 and the summer of 1894, the scale 

 has been discovered in six localities in the eastern United States outside of New Jersey, 

 while in the latter State it occurs at many points. He traced the introduction to two 

 nursery tiims in the state of New Jersey and one in Missouri. He detailed in full the 

 remedial work which has been undertaken by the Division of Entomology of the United 

 States Department of Agriculture in each of the six eastern localities, and showed that 

 by virtue of the active measures which have been taken, the insect will probably be 

 stamped out in the east by the close of the season. 



The next paper was on the same subject, and discussion was therefore deferred.
