During the year some good work has been done in this important order. 

 Dr. E. M. Walker writes: "I have examined some 800 specimens from the 

 Prairie Provinces and British Columbia, collected chiefly by Messrs. T. N. 

 Willing and N. Criddle, Prof. W. J. Alexander and the late Dr. Fletcher. 

 These will form the basis of a paper which I have about completed. Besides 

 this material I have yet to report on collections m.ade at Go Home, Georgian 

 Bay, the Temagami region, Fort William and Xepigon, Ont."
