In the order Hymenoptera numerous additions have been made 
to collections, including some of great interest. A feature of the year 
has been the abundance of parasitic species. Mention may be made 
of two which did good service in destroying the eggs of two very in- 
jurious pests of the garden, viz., the imported current sawfly (Nemalus 
ribesii) and the zebra caterpillar of the cabbage and other plants 
(Mamestra picla). An extended notice of these will be found in the 
forthcoming report of the Experimental Farms. A list of our Phyto- 
phagus Hymenoptera is now ready for publication when space permits 
in the Naturalist. 
Several collecting expeditions were made during the summer, the 
most interesting of which was a visit of two of the leaders to Sudbury, 
where in company with Mr. J. D. Evans, a member of the club and an 
energetic entomologist, they spent three days collecting. Although the 
weather for a portion of the time was not propitious, a large number of 
rare and interesting forms were secured.

Report of Observations of Injurious Insects and Common Farm Pests, during 
the year 1892, with Methods of Prevention and Remedy. 
The Sixteenth Annual Report, on the pests injurious to the British 
farmer and gardener, by Miss Eleanor A. Ormerod (a corresponding 
member of our Club), indicates that this talented lady is still indefa- 
tigably prosecuting the useful investigations which have made her 
famous in the field of economic entomology. The present report attains 
a length of 163 pages, and treats of a score or so'of interesting subjects, 
of which a few only can be here indicated. The Sawfly, whose 
injuries to the apple were noted in the previous report, has been bred 
through its several stages and has proved to be Hoplocampa ( Teuthredo) 
testudinea, Klug. This Sawfly inserts its egg in the embryo apple, 
when the fruit is setting, and the larva, when hatched, feeds in the 
interior of the fruit and destroys it. Several European sawfiies have 
already reached Canada, and inflicted a great deal of injury, and it is
