]^2 B. C. ENTOMOLOGICAL SOCIETY 



Much of the material in this latter section is as yet unidentified, but 

 when thoroughly worked over, there will probably be found amongst 

 them several new to science as well as many new to B. C. The col- 

 lectors who have assisted Mr. Downes with material, etc., are : E. M. 

 Anderson, E. R. Buckell, A. W. Hanham, Mrs. W. W. Hippisley, A. W. 

 Phair, M. H. Ruhman, R. Sherman, R. C. Treherne, E. P. Venables and 

 R. C. Woodward. 



Mr. E. R. Buckell, who has been making a special study of the 

 grasshopper outbreak in the Chilcotin country, has added considerably 

 to our knowledge of the order Orthoptera, and has recorded several 

 species new to British Columbia. 



The order Thysanoptera is one of the most neglected orders in 

 Canada, but Mr. R. C. Treherne has made an exhaustive study of one 

 of its chief families., i.e., the Aeolothripidae. In No. 12 of our Pro- 

 ceedings (Feb. 1918) Mr. Treherne gave a very interesting paper on 

 this family, which was of great taxonomic value. It contained refer- 

 ences to all the known species, with keys to the genera and species, also 

 a plate of diagrammatic outlines of the wing and female antenna, shaded 

 to show the specific characters of 10 different species. 



In a further article in the Can. Ent., August, 1919, Mr. Treherne 

 described a new species of Thrips from Vernon, under the Aeolthrips 

 auricestus. As some of the species of this family are of great economic 

 importance, Mr. Treherne's work in this group is very valuable. 



I think, gentlemen, that you will agree with me that this Society 

 has justified the twenty years of its existence, and that we have a record 

 of which -We can be justly proud. 



In conclusion I wish to thank you for giving me so patient a hearing, 

 but as this is probably the last time that I shall address you as your 

 President, I would like to say that this recapitulation of our past efforts 

 should be a stimulus to every one of us to do his best in his own selected 

 field, for much work yet remains to be done.
