Extract

During the year 1950 I enjoyed the opportunity of examining the collections of Odonata made by the Northern Insect Survey, a co-operative project of the Canadian Department of Agriculture and the Canadian Department of National Defence. For this privilege I wish to express my thanks to Dr. G. P. Holland and the members of his sraff in the Systematics Unit of the Division of Entomology, particularly to Dr. T. N. Freeman, co-ordinator of the Survev, and Mr. W. A. Brown for “their kindness in providing laboratory facilities during visits to Ottawa and for shipping material to Toronto.
