The author urges the advisabihty of introducing the study of 

 entomology as part of the regular curriculum of schools, more par- 

 ticularly in Canada, where the bulk of the population is agricultural 

 and rural. In his opinion, every teacher should have cpialified in this 

 subject before taking up his profession.

The author reviews the chief insect pests of the northern United 

 States, and the methods most generally employed against them, with 

 a view to their control should they become serious pests in British 

 Columbia. These include : — Cydia pomonella, L. (codling-moth), 

 Eriosoma lanigerum, Haus. (woolly aphis), Eucosma {Tmetocera) 

 oceUana. Schiff. (bud-moth), Taeniothrips inconsequens, Uzel, {pyri, 

 Dan.) (pear thrips), and Eriophyes ribis, Nal. (black-currant bud-mite).

 infest Stored Products. —Pror. i;?. C. Entotn. Soc, Victorw, 1916,

Insects causing serious losses to flour, stored grain, etc., in various 

 parts of Canada, include Ephesiia kuJniiella (Mediterranean liour-moth), 

 Plodia interpunctella (Indian-meal moth), Pyralis farinalis (meal snout 

 moth), Sitotroga cerealella (Angoumois grain-moth) and the weevils, 

 Calandra granaria (grain weevil) and C oryzae (rice weevil). 

 Experiments for their control by superheating have shown very 

 satisfactory results. This is preferable to fumigation, as it reaches 

 places inaccessible to gas. Detailed results of expermients are given, 

 and these show that a temperature of 125° F. maintained for about six 

 hours kills all stages of the insects present.

This paper gives an account of the cabbage aphis. Aphis hrassicae, 

 and the Braconid, Aphidius {Diaeretus) rapae. Curt., which is largely 

 responsible for its control. In dry, cold latitudes, it is possible to 

 encourage this parasite without aiding the Aphid by collecting all old 

 stumps and refuse in the autumn or winter and placing them in a heap
