them or 28.12% were found to have been eaten into and destroyed 

 by 5th and 6th stage A', bethunei larvae. On July 12 and 13, of 

 1913, a collection of 201 M. disstria cocoons was made and 70 of 

 them or 34.82% were found to be destroyed in the same manner. 

 On July 12, 1913, 75 Malacosoma americana cocoons from apple 

 at Deepbrook, N. S., were examined and 7 of them were found 

 to have been destroyed by X. bethunei larv». In 1913 .Y. bethunei 

 was no further advanced than M. disstria and so was a consider- 

 able factor in the control of the latter on apple. In 1914 M. 

 disstria was almost as numerous as during the previous season, 

 and was greatly retarded by the season, as were apple trees on 

 which it was feeding. X. bethunei was not so numerous in 1914 

 as in 1913, and for some reason was not very much retarded by 

 the season, consequently most of them had pupated before the 

 M. disstria larva; spun up their cocoons so the percentage killed 

 by X. bethunei was much less than during the season of 1913. Of 

 217 cocoons of M. disstria collected from apple on July 17,. 1914, 

 only 13 or 5.99% were eaten by A', bethunei. 



THE ENTOMOLOGICAL SOCIETY OF ONTARIO. 



The Forty-fifth Annual Report of the Entomological Society 

 has just been issued by the Ontario Department of Agriculture, 

 Toronto. The President's address is a valuable contribution to 

 the history of applied entomology in Canada, by Provinces. The 

 insects of the year (1914), both in Ontario and Quebec, are described 

 by several observers, and valuable suggestions are given as to their 

 control. Among the other practical papers presented are those 

 dealing with "The Army Worm in 1914," Experiments with 

 Poisoned Bait for Locust Control," "An Imported Red Spider 

 Attacking Fruit Trees," and "Control of Forest and Shade Tree 

 Insects of the Farm." The more purely literary contributions 

 comprise a very discerning biographical sketch of the celebrated 

 French entomologist, Jean Henri Fabre, and a chatty article on 

 "Mountains and Hills." The Entomological Record for the \-ear 

 is, as usual, most complete and informing. The many illustrations 

 are a valuable feature of the report, a copy of which will be sent 

 to any entomologist upon application to the Department. — (Press
