Young locusts began to appear in noticeable numbers towards the 

 end of May. In Ontario and Quebec the insects occurred in June in 

 exceptional numbers, the chief damage being done by Melanoj)lus 

 atlantis (lesser migratory locust). The modified Kansas bait formula 

 was used, consisting of :■ — Bran, 20 lb. ; Paris green, 1| lb. ; molasses, 

 2 quarts ; oranges, 3 ; water, 2| gals. The farmers of St. Etienne, 

 Quebec, co-operated with one another and the 20,000 acres of this 

 parish were treated with the poison bait in the week beginning 4th June. 

 When the author visited the locality on 23rd June, locusts could only 

 be seen in one or two small areas owned by an outside corporation. 

 The farmers appreciated the results very highly, for many farms had 

 been abandoned owing to the complete devastation caused by the 

 locusts in previous years. Sandy areas that had been reclaimed had 

 reverted to the original condition, as the locusts had destroyed all 

 grasses and vegetation which kept the sand from drifting. Old pasture 

 or meadow land known to attract locusts for oviposition should be 

 ploughed at least 6 inches deep after the eggs have been laid, either 

 in late autumn or in spring before May.

Only six cases of San Jose scale [Aspidiotus perniciosus] have been 

 located this year by the provincial inspectors, and these were found on 

 plants imported prior to the inauguration of the government inspection 

 of nursery importations in 1912, not a single case being met with 

 on subsequent importations. The comparative figures are very striking. 

 In 1912, 750 cases were discovered ; in 1913, 64 ; in 1914, only 4, 

 and in 1915, only 6 cases to date, and these all on plants imported 

 prior to 1912.

 miner in Gaultheria shallon). — Proc. Entom. Soc. British Columbia, 

 Victoria, no. 6, June 1915, pp. 111-114, 1 fig. 



Gaultheria shallon, a shrub which is plentiful in the coast region, is 

 attacked by the leaf- miner Phyllorycter {Lithocolletis) gaultheriella. The 

 mines occur near the upper side of the leaf. The first pupae were 

 collected on 18th July ; these changed to adults on 20th and 21st 

 July. At the time of pupation the leaf becomes puckered up and the 

 pupa is found attached to its surface by a thread. A later brood 

 hibernates in the adult stage. The larval and pupal stages are 

 described.

Beetles of several families were observed on cotton. The Cetoniid, 



Plaesiorrhina trivittata, Sch., was common and the Chrysomelid, Ootheca 



mutabilis, Sahib., fed on the leaves early in the season. A flea- beetle 



which occurred in December and January on the leaves of peas, maize
