of the plant that should be devoted to vipeuing its fruit, is required 

 to repair the damages inflicted on its leaves. 



If fumigation in the field be tried, its success will be much increas- 

 ed by using a small canvas tent which can be let down over the vines 

 and kept there for a litttle time to retain the smoke, though entirely 

 satisfactory results will hardly be obtained in this way. Another 

 method of some value is to carry lighted torches through the vine- 

 yard at night, beating the vines lightly at the same time. The insects 

 will be attracted to the light as they fly from the disturbed vines 

 and perish in the flames. It is well, also, to remove all rubbish 

 from near the vines, and frequently rake the ground late in the fall 

 and early in the spring, to expose the hibernating insects to the 

 frosts. 



About the middle of August the attention of this Division was 

 called by Hon. J. H. Demond, of Northampton, to the condition of 

 the grape vines in his grapery. A special agent, sent to examine 

 them, reported that the leaves were badly discolored, and that leaf- 

 hoppers were present in large numbers. The remedy used in this 

 case was that of fumigating with pyrethrum. The grapery was 

 tightly closed and the powder scattered on burning coals carried 

 under the vines. The treatment was entirely successful, all the in- 

 sects being destroyed. A similar experiment tried on a vine in the 

 open air in Amherst gave much less satisfactory results. 



The Glassy-winged Soldier-bug (Hyaliodes vitripennis Say) de- 

 vours many of these pests, and is their only insect enemy so far as 

 known. It belongs to the Heteroptera, the other group of the true 

 bugs, and is rather larger than the leaf-hopper, and when mature is 

 pale green with a pinkish head and thorax, and the wings are trans- 

 parent with a pink cross band. This insect should not be destroyed. 



ANTS. 



Small ant hills in smooth lawns, and in the cracks or along the 

 edges of walks, much injure the otherwise neat appearance of the 

 grounds about our houses. During the past year man}- inquiries 

 how to drive away the industrious nuisances have been made, and a 

 number of experiments have been conducted, to discover a remedy. 



In Bulletin No. 11, of the Division of Entomology of the Depart- 

 ment of Agriculture is a report of experiments made in Indiana 

 for the same purpose. These experiments were : 1. Carbolic Acid
