Colkoptera. --Several good additions have been made in this order. 

 The more notable of which are the following : Diaelus teter; Oodes 

 Jluvialis, hybernating under moss at St. Louis Dam, with Lachnocrepis 

 paralklus; Donatio, pubescens taken in small numbers on bulrushes along 

 the Rideau river early in June; Toxotus vittiger, twelve males of this 

 handsome longicorn were taken at Casselmanon June 13th ; Hypomolyx 

 pinicola, one specimen, and Ditylns coaruleus, two specimens, with 

 numerous examples of Tritoma humeralis were taken on the same 

 occasion. An interesting addition to the list was made in Aphodius 

 prodromus, a European species recorded from the Northeastern States 

 and as far west as Montreal, but not observed here until last spring 

 when it was taken in some numbers at Ottawa and Caselman. 



Neuroptera. Very little has been done so far by members of 

 the club in collecting and studying the true Neuroptera ; but in the 

 Pseudoneuroptera Mr. T. J. MacLaughlin has continued his collecting 

 again this year. Last summer was particularly favourable for the 

 insects of this family; no less than eight species were taken which had 

 not been taken here before. Several specimens of the rare Diplax 

 costifera were captured late in the summer, the first by Master Stephen 

 MacLaughlin at the rear portion of the Powell property to the north of 

 Bank street ; others were taken later in the same locality and at the 

 Experimental Farm. Previously only one specimen had been taken, in 

 1886. This species resembles the female of Diplax rubicitndula, the 

 most apparent difference is that the anterior margins of the wings of 

 costifera are conspicuously shaded with a yellowish brown tint. 



Hemiptera. Several additions have been made to the list pub- 

 lished in June, 1892. These will be submitted for publication later, 

 when some unidentified species have been determined. Poztilocapsus 

 litieatus and Lygus pratensis were noticeable from their abundance and 

 injuries in gardens. An important discovery has been made by Mr. 

 Slingerland, of Ithaca, that the former of these hybernates in the egg 

 state in the twigs of bushes. This knowledge indicates judicious 

 pruning as a means of checking the increase of this pest. 



1 [ymekoptera. - A list of the phytophagous species observed during 

 the season was published last January. The only species noticed as 

 unusually abundant were the Ash Saw-fly, Monophadnus bardus, Say ;
