42 THE REPORT OF THE No. 19 



This library which is one of the most complete entomological libraries in 

 America is continually being used by members of the Society and by 

 students specializing in entomology at the Ontario Agricultural College. 



The collections of insects belonging to the Society have been materially 

 added to during the year and considerable work has been done in going 

 through the cabinets and rearranging the specimens. 



The Canadian Entomologist, which is published by the Society, is now 

 in its 40th volume. Volume XXXIX, which ended with the December, 1907, 

 number comprised 423 pages, with 11 full page plates and 23 figures in the 

 text. No less than 73 dift'erent entomologists contributed to the volume, 

 and 11 new genera, 216 new species and 5 new varieties are described. 



These papers are of a high character and in a report like this it is 

 impossible to mention very many of them. Some of the more important, 

 however, are. "New Micro-lepidoptera," by Mr. W. D. Kearfottj "New 

 species of North American Lepidoptera," by Dr. W. Barnes; "Notes on
