Acknowledgments. — I take pleasure in gratefully acknovi'ledging my obligation 

 to my many correspondents in all parts of the Dominion, to practical farmers who have 

 much aided the work of the Division by promptly reporting outbreaks of injurious 

 insects and noxious weeds, by sending specimens, and at request making observations 

 ■upon points of special interest. My thanks are also specially due to the following 

 specialists who have helped me on many occasions with the exact identifications of 

 species of plants and insects which were unl^nown to me : 



Prof. John Macoun, of Ottawa, for the identification of plants.

 and the ofiicers of his staff, for information concerning parasitic fungi. 



Dr. L. O. Howard, Chief of the Bureau of Entomology, Washington, U.S., and 

 the ofiicers of his staff, for the identification of scale insects and species of various 

 orders. I am under obligations to Dr. Dyar, and Messrs. Marlatt, Coquillett, 

 Chittenden and Busck. 



Dr. J. B. Smith, New Brunswick, N.J., who has examined and named large num- 

 bers of noctuids and other moths for this office and for Canadian collectors. 



Mr. W. D. Kearfott, Montclair, N.J., who has been untiring in his efforts to help 

 our collectors in the identification of microlepidoptera. 



Mr. W. H. Harrington, Ottawa, for identifying coleoptera. 



Dr. E. M. Walker, Toronto, for examining and naming large collections of Cana- 

 dian odonata.
