 the meeting in Washington of the Entomological Club of the American Association for the Advance- 

 ment of Science. 



Five numbers of the 24th volume have been issued during the current year, each of them with an 

 increased number of pages ; 59 new species of insects have already been described, and several papers 

 of more than ordinary value and interest have been published. 



In addition to the monthly magazine, the society presents an annual report to the Legislature of 

 Ontario. The twenty-second was published by the Department of Agriculture in January last. This 

 report (for 1891) contains an account of the proceedings at the annual meeting of the society, the 

 president's annual addiess, the i-eports of the officers, the Montreal branch and the sections, and the 

 papers read on the occasion. 



The president, in his address, drew the attention of the society to the most serious Insect attacks 

 of the year, and gave an account of the ravages of the " Eye-.spotted Bud-moth " (Tmetoeera ocellana), 

 the "Le-sser apple-leaf folder" {Teras minuta), the " Oblique-banded Loaf-roller" {Cacœsia rosaceana), 

 the Canker-worms {Anisopteryx vernata and powetaria), Cut-worms, the Pearwcevil {Bruchuspisi), the 

 Turnip Flea-beetle, the Striped Cucumber-beetle (Diabroiica vitiata), and other more or less injurious 

 insects. 



Among the papers published in the annual report may be mentioned the following : " Can Insects 

 Survive Freezing?' and "Pamphihi Manitoba and its Varieties," by H. H. Lyman; "Nenatus 

 Erichsonii," the Larch Saw-fly, whose destructive ravages among the tamarack swamps of the Province 

 of Quebec are fully related by the Eev. T. W. Fyles ; ' A Microscopical Examination of an Unex- 

 panded Wing of Callosamia Promethea," by J. A. Moffat; " An Account of Some of the Collections of 

 Insects in England and Germany," by G. Geddes; "The Northern Mole Cricket," by J. Fletcher; 

 "Notes on Japanese Insects," by W. H. Harrington ; "The Moose-fly," by W. A. Snow. 



The various sections of the society, which were organized about two years ago, report very satis- 

 factory progress. The Ornithological section state that their " membership, while not large, is 

 enthusiastic; " they have prepared a list, which is published in the annual report, of 97 birds known 

 to breed in the county of Middlesex, Ontario, and of 20 other species observed in the same neighbour- 

 hood, and which will probably be found breeding there. The species are distinguished into those 

 which are decidedly beneficial on account of their feeding habits, those which are neutral, and those 

 which are open to doubt as being possibly injurious. 



The Microscopical section have held numerous regular meetings and several popular exhibitions. 

 The objects to which their attention has been chiefly devoted, were the manipulation of the micro- 

 scope and the preparation of objects, and the examination of ferns, algœ and fungi, including the 

 destructive Black-knot on fruit trees. The Botanical Section held weekly meetings throughout the 

 greater part of the year, and have begun the formation of a collection of native plants, which is 

 deposited in the rooms of the society ; a floral calendar has been kept; two messes new to Canada 

 have been discovered, and seventy species of fungi have been added to the North American list. 



The members of the Geological section have held evening meetings every week, at which they 

 applied themselves to the serious and methodical study of the science, and when the season admitted, 

 frequent field excursions were made for practical work. During these they covered a large area of 

 country, and gathered many rare and valuable specimens of fossils. 



The formation of these sections of an entomological society for the encouragement of work in 

 other departments of science has thus been amply justified. The results have been most satisfactory, 

 and the cheerful assistance given by the members of one section to those of another has been most
