ders of insects. Mr. Keek explored the Valley of the Mayo 

 River, Yukon Territory, in 1904 and worked along Lansing 

 River, Hell River and Ladue River in the same Territory in 1905, 

 Mr. Wilson was exploring on the Hudson River slope in 1904, 

 and in the Temagami district in 1905. As both of these gentlemen 

 trok great care to label their specimens accurately, even the 

 small number they brought back, have distinct and great scienti- 

 fic value. Mr. Andrew Halkett, who was naturalist on the Nep- 

 tune expedition under Commander Low, in 1903-4, brought 

 back a surprisingly large number of species of insects from the 

 Hudson Bay region. Mr. H. H. Lyman, of Montreal, who 

 joined the Labrador expedition, sent out to observe the total 

 eclipse of the sun, found opportunity to collect specimens and 

 make observations. Mr. Norman Criddle and Mr. T. N. Wil- 

 ling, two of our Northwestern members, have prosecuted their 

 studies of insects and plants most vigorously and with very 

 important results. Many new species have rewarded their ef- 

 forts and a vast amount of useful knowledge has been accumu- 

 lated during the past few years. 



Of our local members perhaps Mr. C. H. Young's work 

 among the micro-lepidoptera is most worthy of mention. The 

 exquisite manner in which Mr. Young prepares his material is 

 well known to us all but the value of his work is chiefly due to his 

 skill in rearing large series of insects so as to compare the limits 

 of variation. Mr. W. D. Kearfott, of Montclair, N. J., has been 

 indefatigable and most generous in helping our members with the 

 indentification of their captures of these minute and most beau- 

 tiful moths. Mr. W. Metcalfe has taken up the study of the 

 order Hemiptera and is gradually compiling a complete list of the 

 Ottawa species. His material has been named by the leading 

 specialists and we hope that it will soon be ready for publica- 

 tion. 



Our two highly esteemed corresponding members, Messrs. 

 J. B. Smith, State Entomologist, of New Jersey, and Prof. H. 

 F. Wickham, of the Lmiversity of Iowa, as in the past, have 

 rendered invaluable service to our members by helping with 

 identifications and sending us fcr the Library their useful publi- 

 cations.
