Annual report of the Fruit Growers' Association of Ontario, 1898 . ippi, however, thepotato fields were more plentiful and it began to make better time, actually arriv-ing on the Atlantic coast in 1874, seven years ahead of time, its average rate ofprogress being 88 miles per year. This rate, however, was not uniform, the northerncolumns of the army made the most rapid progress; the southern oolumnstravelling through a country where potatoes were not so much grown, and under abroiling hot sun, lagged far behind. The invasion of Ontario began in July of 1870, at two points on the western frontier,namely, near Point Edward and near Windsor. During 1871 they came on in increasingnumbers, and it was said that during that summer the Detroit river was literally swarmingwith them. They were crossing on ships, chips, staves, boards, or any other floating objectthat presented itself. By June of that year they were common around London, and, informs me, that later that year they had reached as far as Gait. I can well 7 EN. 98 ENTOMOLOGICAL remember the first one I ever saw ; it must have been in the summer of 1872 I was thena little chap attending school on the historic battle field of Lundys Lane, and I little knewthen that I had met an enemv that would refuse to be driven from the country, for theirinvasion was one not only of conquest but colonization wherever they went. A few beetles were sent to us last summer which were covered with a very interestingparasite known as Urupoda Americana. These are little mites about the size of a smallnin head and of a flax seed brown colour. Each beetle was so thickly covered with themthat hardly any part of its body was visible. The infested beetles were placed upon acotato plant along with some of their healthy relatives in hopes that their enemies mightincrease and subdue them, but after a few days the infested beetles had disappeared andthe parasites with them, while the healthy beetles fed on serenely. 6 Grass
