not be omitted, as it will be of great benefit to the beginner, and the plates will serve to give a 

 good idea of the general appearance of most of the genera he is likely to meet with. 



In regard to Canadian Orthoptera, it may be mentioned that, since the last instalment of 

 the writer's " Notes on some Ontario Acridiid;e " was printed, he has added four more species 

 to the number, and is now engaged in preparing a complete list of the Acridiidie of Ontario. 

 These four species are the following : — 



Tryxalis brevicor')us, L. Pt. Pelee, Aug. 8, 1901. 



Orphnlella pelidna, Burm. Sarnia, Aug. 12 and 14, 1901. 



Trimerotropis huroniaiia, n. sp. Southampton, Aug. 20, 21, 29, 1901. 



Paroxyn floridana, Thos. Arner, Aug. 9, 1901. 



Nothing of any importance has been written on the other families of Orthoptera in Canada, 

 but the writer has for some years been making a collection of the Ontario forms, and will soon 

 have a preliminary list of the Locustidiw ready for publication. Of the last-named family only 

 eight species have been recorded from Ontario, and the lists from the other parts of Canada 

 are no better. The writer, however, has taken twenty-two species in the province, seven of 

 these having been taken for the first time this season. They are the following : — 



Scndderia te.censis, Pict.-Sauss. Pt. Pelee, Aug. 8 ; Arner, Aug. 9 ; Sarnia, Aug. 12, 14 ; 

 VValpole Island, Aug. 13. 



Conocephalus Nebrascensis, Bruner. Sarnia, Aug. 12. 



Orchelimum nigripes, Scudd. Pt. Pelee. Aug. 7" 



'* indianense, Blatchl. Sarnia, Auf/. 14 ; Arner, Aug. 8. 



" longipenne, Scudd. Pt. Pelee, Aug. 8 ; Walpole Island, Aug. 13. 



Xiphidium aftemiatum, Scudd. Pt. Pelee, Aug. 8 ; Walpole Island, Aug. 13. 



Atlariticvs pachymerns, Scudd. Arner, Aug. 9. 



Of the Gryllidit! and Blattid;e, the writer's collection contains a number of species as yet 

 unrecorded from Canada. Of these, a few Gryllidse were taken this year for the first time, 

 Nemobhis pidvstris, Blatchl., from Sarnia, Southampton, Owen Sound (Aug.), and Lake Simcoe 

 (Sept.) : and N. maadntiis, Blatchl. (ToVjermory, Aug. 25), being noteworthy. The others have 

 not yet been satisfactorily determined. 



Collections of Orthoptera were made at the following localities during the past season : — 



Toronto, Lake Simcoe, Leamington, Point Pelee, Arner, Chatham, Sarnia, Walpole Island, 

 rSt. Clair River) ; Goderich, Southampton, Tobermory, and other points in the Bruce penin- 

 sula and Owen Sound. 



In addition to the above, collections of Orthoptera have been made at Aweme, Man., by 

 Mr. Norman Griddle ; also in Central Manitoba and in the Okanagan and Nicola valleys, in 

 British Columbia, by Dr. Fletcher.
