In the present report, I have begun the consideration of the very extensive collections of crane-flies from Alberta that have been received from the Canadian National Collection, through Mr. Curran ; tlie very extensive series collected by Mr. Owen Bryant; a series from Banff, collected by Mr. Garrett; and the collections of the University of Alberta, sent through the kindness of Professor Strickland. I wish to express my sincere thanks to all of the above mentioned gentlemen for this kind co-operation in making known the Tipulid fauna of Alberta, a list that will certainly exceed in numbers that of any other of the Canadian Provinces with the single exception of British Columbia.
