ably as.sisted in 1917 and 1919 by Mr. E. H. Blackmore, who undertook to 

 give instructions in the determination of the important famiHes of the 

 Lepidoptera. 



With the opening of the 1919 season the following officers were actively 

 engaged in economic-insect investigations : Mr. W. Downes, who during 

 1918 and 1919 had been on temporary employ of the Dominion Entomo- 

 logical Branch, was appointed as permanent officer of the Dominion Branch 

 on September ist, 1919; Mr. E. P. Venables, who had recently returned 

 from active military service in Palestine, was placed on temporary employ 

 on the Dominion Branch for six months dating from May 15th until 

 November 15th; Messrs. M. H. Ruhmann and E. R. Buckell under the 

 Provincial Service ; and the writer, who assumed general direction of the 

 work. It will be seen that the Dominion and Provincial services are now 

 co-ordinated so as to prevent overlapping of industry. The necessary 

 projects are now grouped under crop insects: Mr. Downes, located at 

 Victoria, was placed in charge of small-fruit investigations ; Mr. Venables, 

 at Vernon, on tree-fruit studies; Mr. Ruhmann, on vegetables; and Mr. 

 Buckell, on range and cereal insects. In addition, Mr. Hearle, at Mission. 

 is continuing his studies on the mosquitoes, and Mr. Baird, at Agassiz, on 

 natural-control features of certain insect pests. Furthermore, the field 

 officers of the Provincial Horticultural Branch were engaged in collecting 

 data and reporting the existence of insect troubles in their respective 

 districts, and the quarantine and inspection work under the direction of Mr. 

 W. H. Lyne in A'ancouver was productive of many notes of entomological 

 interest. Thus the work was planned for 1919. 



The year 1919 was productive in the following notes of special 

 entomological interest : The writer received the work of Marmara 

 pomonella, a lepidopterous fruit-miner, from Sorrento on October 25th. 

 This same insect was noted by Mr. M. H. Ruhmann in 1917 in apples 

 received from Creston on October 25th. The identification was made by 

 Mr. Quaintance, of the United States Federal Entomological Bureau, 

 Washington, D.C. In midsummer larvae of Mineola tricolorella were 

 taken at Okanagan Landing and bred through to the adult, the deter- 

 mination being made by Dr. J. JMcDonough, of Ottawa. Argyroploce 

 consanguiniana was also reared from apple-foliage at \'ernon. This 

 insect had previously been noted from the Province in 1914, when it 

 was bred from larvae taken on apple at Hatzic, in the Lower Eraser 

 Valley. Mr. Downes, in addition to establishing the identity of many 

 small-fruit insects from Island districts, this year reported Apateticus 

 crocatus, a pentatomid bug predaceous on the caterpillars of the tent- 

 caterpillar and oak-looper at Victoria. During IVIay Mr. Buckell, in 

 association with the writer, was able to establish the very interesting 

 and doubtless important note on the existence of Entpmophthora (Tari- 

 chium) megaspermum, an entomophilous fungous disease on noctuid 

 larvae attacking the Chrysothamnus bushes at Keremeos. The deter- 

 mination was made by j\ir. Speare, Mycoentomologist of the United
