The following are species of more than usual interest which have 

 been found at Ottawa, and are among those which have not yet 

 been recorded from the district : 



Desmopachria convexa, Aube, Bidessus lacustris, S ly, Coelambus 

 turbiclus Lee, Deronectes depressus Fab.. Hydroporus pulcher, Lee, 

 H.solitariuSy Sharp, Ilybius pleuriticits, Lee. Agabus semipunctatus,

 stagnalis. Fab., H. peceus, Lee. Dytiscus kybridus, Aube, D. 

 marginalis, Linn, and Acilius setnisutcatiis, Aube. 



The publication of a complete list of the Ottawa Dytiscidae, 

 is most desirable, as that published in Transactions No. V, page 

 J3, is obsolete and several of the determinations were erroneous.

In some places the ground was carpeted with mocnseed, 

 (Menispermum Canadense). It was too early in the season to get
