of prevention ; at the same time there does not seem to be any permanent 

 remedy if you do not close your houses up in the spring time. The cutworms 

 were very abundant and our old stand-bys, the codling moth and onion mag- 

 got were, as usual, destructive. The currant sawfly was also abundant this 

 year, though for two years previously I left some bushes unsprayed and they 

 were not at all eaten. Tent caterpillars were not numerous in the spring, 

 but the Fall Webworm was to be seen nearly everywhere in September. The 

 Tussock moths, though common as moths, do not do much harm as far as 

 noticed here. There has been no complaint of the Pea weevil, though I have 

 asked several intelligent farmers of the neighborhood to inform me of their 

 ravages if noticed. Altogether I might say that this district has not been 

 troubled with any serious outbreak of insect pests. Though the season has 

 been an exceptionally fine and warm one, as I said before, I have not been 

 able to give much time to entomology this year, but I have added one more 

 Plusia, also Harrisimemno, tvisignata and Arsilonche alboverwsa to my col- 

 lection of local moths. I also have to report the second capture of Junonia 

 coenia in Orillia.

The Tussock moth, as usual, did a good deal of damage to the shade trees 

 in Toronto. About the middle of July the caterpillars began to let them- 

 selves down from the trees by a thread to the ground, and then ascended the 

 trunks to pupate. Many of them were very small, and had a sickly yellowish 

 look, and made poor little cocoons. Such, specimens, I imagine, had been 

 suffering from parasites, and on some trees the proportion of these small 

 cocoons that seemed to come to nothing was very large. I saw a cluster of 

 eggs on August 5th, but there do not seem to me to be as many eggs as usual 

 on the infested trees. 



The row of chestnut trees from which I had the c6coons collected last 

 year, had some caterpillars on this year, but they were not nearly so numer- 

 ous as on some neighboring trees, so that the destruction of the Qgg masses 

 last year evidently did some good. 



Apple trees around Toronto have been a good deal damaged by the Cod- 

 ling moth. In two orchards that I examined, one in the city and one about 

 a mile outside, a very large proportion of the apples had been rendered quite 

 worthless by the ravages of this pest. 



1 visited Niagara Glen in September, and found the Walking stick in- 

 sects almost as numerous there as they were two years ago. Several large 

 basswood trees had been completely stripped of their foliage by these crea- 

 tures, and I noticed a Chestnut oak (Quercus prinus) some ten or twelve feet 

 in height, with about two-thirds of its foliage destroyed, but the swarms of 

 Stick insects that were upon it must, in a few days longer, have cleared off 

 every leaf. 



Division No. 4. — Hamilton District. By George E. Fisher, Burlington. 



In making my report of insect conditions in the Niagara District, which 

 as a Director of the Entomological Society of Ontario I am supposed to repre- 

 sent, I can speak advisedly of my own immediate section and of such particu- 

 lars ns came to my notice during occasional visits to other parts of the dis- 

 trict.
