At the afternoon session addresses were given by Mr. Arthur Gibson, Do- 

 minion Entomologist, and Dr. A. H. MacKay, Superintendent of Education for 

 Nova Scotia, and a number of papers were read by different members. 



During the past year the fifth " Proceedings of the Entomological Society " 

 was issued. This publication, which comprises ninety-four pages and includes 

 four plates, contains some very valuable data on the various insects studied through- 

 out the year. It also includes an account of the latest insecticide-fungicide com- 

 binations which have been tested in Nova Scotia during the past season*.

REPORTS ON INSECTS OF THE YEAR. 



Division No. 3. Toronto District — A. Cosens. 



With reports from different parts of the province of serious damage done by 

 the Hessian Fly, and from another part of the appearance of the Corn Borer, the 

 Entomological happenings in the Toronto District seem very unimportant. 



The Tussock moth, so much in evidence for several years, has apparently 

 passed the peak of its development and will now decrease in numbers for a term 

 of years. In the western part of the city few caterpillars were seen in districts 

 where the trees have been badly infested for several years. The parasites are clearly 

 establishing a control of the pest, but this natural check has been assisted by the 

 system of spraying and intelligent collection of egg masses carried out by the City 

 Parks' Department. 



Two moths, noted as being unusually plentiful, were the day-flying, black and 

 white Shearmark. Rheumaptera hastata and the Linden Moth, Erannis tiliaria. 

 The latter was common, flitting about the electric street lamps, until the cold 

 spell that commenced October 25th brought its activities to a close. 



The Monarch butterfly was only rarely seen this season and specimens of the 

 Common Sulphur were less numerous than usual. 



Reports from the eastern part of the city indicate that the Soldier Bugs have 

 been more than usually aggressive in their attacks on the Colorado Potato Beetle. 

 These carnivorous insects kill the "Potato Bug" by thrusting their beaks into 

 it, a mode of attack quite different to that of the beetles for which they are often 

 mistaken. 



There is a beetle, Lebia grandis, however, that kills large numbers of the 

 Potato Beetles. It attacks both larvae and adults as well as feeding on the egg 

 clusters of the pest. This insect friend of the gardener is easily recognized by its 

 dark blue outer wings and red-coloured legs and body. 



Other beneficial insects, frequently seen in this district, are the Ground Beetles. 

 There are two common species of them, both of which are distinctly marked. The 

 Searcher or Caterpillar Hunter, Colo soma scrutator, has its outer wings colored a
