and numerous interestincj fossils have been added to the Society's collections ; taken 

 altogether the year's work done by this section has been very satisfactory. The interest of 

 the members has not flagged at any time, but each has seemed anxious to do what he 

 could towards adding to the general stock of information. 



The Microscopical section has also been active. It numbers twelve members, and it 

 has in use eleven first-class micioscopes. Ten meetings have been held by the members 

 for piivate study, and two public entertainments for the benefit of the young people of 

 the cit.y have been given. Special attention has been paid by this section "to fungi, mil- 

 dews upon fruit trees, rust in wheat, etc. Mr. Joim Denton is chairman of the section, 

 and Messrs. Bowman and Dearness, microscopical directors. 



It is generally conceded that the formation of these sections was a happy proceduie 

 that strengthened the Society and increased its usefulness. 



At the last annual meeting the Socif-ty secured the services of Mr. J. Alston 

 Moflfatt one of its member.s who engaged to take entire charge of the Society's rooms, 

 library and collections, and to be a permanent resident official in London. It is felt that 

 the greatest care will be taken by Mr. Mofl[att for the preservation and arrangement of 

 the Society's valuable collections of insects. These have lately been enlarged by the 

 purchase from Mr. Johnson Pettit of Grimsby, of several well filled and well-arranged 

 cabinets of coleoptera, etc., the results of many years' intelligent labor on the part of 

 Mr. Pettit. 



Among the tokens of public recognition of the value of its collections, the Society 

 preserves the medals and diplomas awarded it at the Centennial Exhibition, Philadelphia, 

 in 1876, the Int^n'national Fisheries Exhibition in 1883, and the Colonial and Indian 

 Exhibition in 1886. 



The library of the Society now numbers 1,100 volumes. Among them are such costly 

 works as the Challenger Reports, 20 vols. ; Smith's Collection of Abbott's Illustrations, 2 

 vols. 1797 ; Drury's Exotic Entomology, 3 vols. ; Stephen's P]ntomology, 8 vols. ; Kirby's 

 Entomology, 4 vols. ; Say's Entomology, 2 vols. ; Edwards' Butterflies of North America, 

 2 vols. ; Scudder's Butterflies of New England, 3 vols. ; McCook's American Spiders, 2 

 vols. ; Packard's Monograph of Geometrid Moths ; Lord Walsingham's Illustrations of 

 Typical North American Tortricidaj, 2 vols. ; The American Naturalist, 20 vols. ; Scud- 

 der's Fossil Insects, 2 vols., ete. It is being continually enriched by the printed reports 

 and periodicals from the principal Entomological societies of Great Britain, Australia,. 

 Austria, France, Germany, Inr'ia, Italy, Russia, Switzerland, South America and the 

 United States of America. 



The Society's collections, library, electrotypes, etc., are insured for $3,500. 



The Society reports, through its president, the unwelcome re-appeai"ance of the Hes- 

 sian fly [Cecidomyia destructor, Say), and recapitulates the best methods of dealing with 

 this pest. 



Another intruder that has been brought under the notice of the Society is the grain 

 Aphis {Siphonophora avena;, Fab.), which has appeared in many localities in Ontario. 



The Larch saw-fly {Newaius Erichso7in, Hartig.), after doing incalculable harm to 

 the tamarack forests of Canada, is now diminishing in numbers. A new importation 

 allied to this {Neniatus pallidiventris, Fallen) has made its appearance on willows brought 

 from Russia by the late Mr. Charles Gibb. 



The Mediterranean Flour Moth (Ephestia KiihnieUa, Zeller) whose appearance two 

 years ago in a large milling establishment in Ontario, caused so much consternation, and 

 called forth such vigorous action on tlie part of the Ontario Agricultural Department 

 seems happily to have been stamped out. 



In these days of rapid transit and intercourse with foreign countries, the advent of 

 new insect pests may be looked for. According to a wise provision the directors of the 

 Society must be representatives from the diflerent Aqricultural sections of Ontario. By 

 this arrangement it is hoped the appearance and operations of injurious ie.sects in any 

 part of Ontario will be speedily made known to the Society, and receive careful attention.
