THE CANADIAN ENTOMOLOGIST. 297 



BEETLES FROM NORTHERN BRITISH COLUMBIA. 



BY J. H. KEEN, METLAKATLA, B. C. 



About ten years ago (see Can. Ent., Vol. XXVII, Nos. 7 and 8) I 



published a list of beetles taken by me on the Queen Charlotte Islands. 



The beetles enumerated below were, except where otherwise designated, 



taken on the mainland of British Columbia, on the coast between the 



mouths of the Naas and Skeena Rivers. Some of them were determined 



for me through the kindness of Dr. James Fletcher, the Dominion 



Entomologist, whose valuable help and advice I have now for many years 



enjoyed; the remainder by Professor H. F. Wickham, of Iowa University, 



to whose skill and courtesy I am deeply indebted.
