1^4 THE EEPORT OF THE No. 30 



THE ENTOMOLOGICAL RECORD, 1915. 



Aethur Gibson^ Chief Assistant Entomologist^ Department of Agriculture, 



Ottawa. 



It is gratifying to be able to state that the collection and study of insects is 

 gradually but surely increasing every year in the different provinces of Canada. 

 This, I think, is largely owing to the fact that< economic, or applied, entomology 

 is more and more receiving its due recognition. The importance of local collections 

 of insects to the economic entomologist is indeed of great value, providing, as they 

 do, definite information as to distribution, etc. At Ottawa, as we have previously 

 stated, due provision has been made for a national collection of the insects of 

 Canada, and collectors generally could aid materially in building up this collection 

 by forwarding donations of specimens. 



During 1915 much material collected in previous years has been worked over 

 by specialists, in addition to which large collections have been made during the 

 past season in most of the provinces. Many of these are new records for Canada, 

 while the capture of others in certain districts or provinces extend the known 

 range of their distribution. 



As in years past we have received invaluable assistance in the determination 

 of many specimens from the recognized authorities in the United States and 

 elsewhere. Our special thanks are due to Dr. L. 0. Howard and his associates 

 at Washington — Dr. Dyar, Dr. Banks, Messrs. Schwarz, Crawford, Busck, Rohwer,

 Wickham, of Iowa City, Iowa ; Mr. E. P. Van Duzee, of Berkeley, Cal. ; Dr. Henry 

 Skinner, of Philadelphia; Col. Thos. L. Casey, of Washington, D.C.; Mr. C. W. 

 Johnson, of Boston, Mass.; Mr. Chas. Liebeck, of Philadelphia, Pa.; Prof. H. S. 

 Hine, of Columbus, Ohio ; Dr. J. M. Aldrich, of La Fayette, Ind. ; Mr. Chas. W. 

 Leng, of New York, N.Y. ; Dr. W. G. Dietz, of Hazleton, Pa. ; Dr. F. C. Fall, of 

 Pasadena, Cal. ; Mr. M. C. Van Duzee, of Buffalo, N.Y. ; Mr. C. A. Frost, of South 

 Framingham, Mass. ; Dr. E. C. Van Dyke, of Berkeley, Cal. ; Mr. J. R. de la Torre 

 Bueno, of White Plains, N.Y.; Mr. F. H. Wolley-Dod, of Midnapore, Alta., and

Literature. 



Among the books, memoirs, etc., which have appeared during 1915, and which 

 are of interest to Canadian students, the following should be mentioned: 



Bethune, Rev. Prof, C. J. S. Bibliography of Canadian Entomology for 

 the year 1913; Ottawa, Trans. Royal Soc. of Canada, Third Series — 1914, Vol. 

 VIII, Section IV, 1914. In this contribution references are given to 151 papers; 

 43 of these relate to Economic Entomology, 18 to General Entomology, 18 to 

 Lepidoptera, 21 to Diptera, etc. 



Banks, Nathan. The Acarina or Mites; a review of the group for the use 

 of economic entomologists: United States Department of Agriculture, office of the 

 secretary. Report No. 108. Received December 28th, 1915. This is indeed a 

 very useful contribution of 153 pages. In the introduction information is given 

 on the structure, life-history, classification, etc. Then follows a lengthy dis- 

 cussion on the different families, and many keys are given. Notes on collecting.
