enumerated, fully nine-tenths are recorded from Ottawa 

 or its immediate vicinity. The insects are parasitic in 

 their habits, either in the eggs or upon the larvte of other 

 insects. They are all small, and the majority are so 

 minute as to be difficult of identification without careful 

 microscopical study. They, however, exhibit a consider- 

 able and interesting diversity of structure, and a large 

 proportion of the genera are readily recognizable. 

 Descriptions of several apparently new species are 

 included in the paper, as well as some remarks on previous 

 records, and on the habits of certain species. 

 4. — " The Geology of the More Important Cities of 

 Eastern Canada." By Henry M. Ami, M.A., D.Sc. 

 Communicated by R. W. Ells, LL.L>. 

 The paper discusses the geological formations as seen 

 around the cities of Ottawa, Montreal, Quebec, St. John, 

 Toronto, Hamilton and London. In the last named place 

 the information has been largely obtained by means of 

 borings which have been made in the vicinity, since rock- 

 formations do not appear at the surface in that locality, 

 5. — " Origin and History of Some New Varieties of Wheat 

 Produced at the Dominion Experimental Farms." 

 By Wm. Saunders, LL.D., F.R.S.C, F.L.S., Director 

 of Experimental Farms. 

 In this paper the author traces the history of some 

 of the most promising of the cross-bred varieties of wheat 

 which have been produced during the past ten years 

 at the Experimental Farms. The objects in view in 

 undertaking this work are referred to and some of the 

 more striking instances of success given. 



Particulars as to how these varieties compare with the 

 standard sorts in cultivation are also given, together with 

 facts indicating their adaptability to the different climates 

 of the Dominion.
