Thysanura and Collembola, particularly of the genera Machilis 

 and Japyx of the Thysanura. These were compared with Scolo- 

 pendrella, the typical genus of the class Symphyla, and the closest 

 living relative of the insects. Specimens of these forms were shown, 

 in which most of the features referred to were pointed out. 



The Branch was favoured with the presence at this meeting of 

 Mr. Arthur Gibson, Chief Assistant Entomologist of the Division 

 of Entomology, Ottawa, who gave an interesting outline of the 

 work of the Division both at Ottawa and in the field. He stated 

 that since the new Division- had been established in 1908, under 

 the direction of Dr. Hewitt as Dominion Entomologist, the work 

 had increased very rapidly. This was largely due to the finding of 

 nests of the Brown-tail Moth in importations of nursery stock 

 from Europe, which necessitated the passing by Parliament of the 

 Destructive Insect and Pest Act Sunder the provisions of which 

 nursery stock entering Canada is inspected by inspector; of he 

 Division) and the establishment of Field Stations in the different 

 Provinces. The field work in Nova Scotia and New Brunswick in 

 connection with the Brown-tail Moth was discussed and many- 

 questions asked by members present. Mr. Gibson spoke of his own 

 and Mr. Strickland's work in Alberta in the control of a Cutwrom 

 (Porosagrotis orthogonia) which during the past three years had 

 devastated many wheat fields. A preliminary repor L on the in- 

 vestigation was presented at the recent meeting of the Association 

 of Economic Entomologists. E. Horne Craigie, Sec.-Treas.
