Dr. Fletcher replied that the theory was incorrect, as rye was dis- tasteful to these worms and kept them away. If wheat or oats were plough- ed under instead they would be attracted. A cause of the trouble in the case of melons was that the large quantity of manure employed served as a great attraction to the "Wire-worms. The reason for the ploughing that he recom- mended was that the insect became mature in the second autumn after the eggs were laid; ploughing in August destroys them in the pupa state, and the repetition in September disturbs the beetles in the ground and by bring- ing them to the surface ensures the death of a large proportion. Mr. Evans said that he had known acres of tomatoes to be destroyed by Wire-worms. Mr. Fisher stated that he had observed the same thing. He had also found that if tomatoes were sown early and well-grown in hot-beds before planting out, they were then large, over-grown and tender; if the weather should be unfavorable, the lower leaves became blighted. Much the same thing happened with potatoes which had grown rapidly. This year in his neighborhood the Colorado beetle had in many cases left the potato plants and attacked the tomatoes, causing much destruction; it had also been very bad on egg-plant. Dr. Fletcher said that the Colorado beetle was worst of all on egg- plant, very bad on potatoes and least injurious to Mr. Fisher next referred to the Squash-bug (Fig. 2), commonly called the "Stink-bug" and sometimes ''the Bishop-bug" (Anasa tristis). Though it had been abundant and very injurious for a long time, this year he had seen none. Last year it took
