chick was almost ready to emerge. As these birds doubtless 

 incubate about 30 days, the one egg must have been laid about 

 February 19th, at which time there was absolutely no sign of 

 approaching spring and the thermometer often fell to the neigh- 

 bourhood of zero in the night. The bird must therefore have 

 laid these eggs entirely by fnith in the hope of better weather to 

 come. 



The later breeding birds have also been affected by the long 

 spell of early, fine weather, and the first set of Red-shouldered 

 Hawks eggs for the year was taken on April 5th, five days earlier 

 than the earliest previous record. Another was taken on April 

 iith. Crows were noticed building on March 28th, 



ENTOMOLOGICAL NOTES. 



Tent Caterpillars [Clisiceampa disstria) in Rat Portage 

 District, Ont. The Rat Portage district suffered severely from 

 the above pests during the latter part of June, when an area of 

 many miles in extent, covering both the mainland and the islands 

 on Lake of the Woods was devastated by immense numbers of 

 these caterpillars. They fed very generally so that all classes 

 of deciduous trees and shrubs suffered, and the trees were literally 

 stripped. During the first week in July the larvae were full fed, 

 and, helped by the unusual amount of rain, the trees at this writing 

 are putting forth some scanty supply of leaves. No parasites were 

 noticed in the larvae collected. 



The Negundo Leaf-roller [Cacoecta semiferana Walker) 

 IN Winnipeg, Man. The Ash-leaved Maples or Negundos were 

 seriously threatened with this pest early in the season, the trees 

 being covered with rolled leaves. The very wet weather of June, 

 however, seemed to completely exterminate them. The affected 

 leaves shrivelled up hard, seemingly under the influence of warm 

 sunshine following rain, and afterwards no larvae were seen. 

 Search failed to reveal any parasites or other enemies. 



A Plant-louse on Willow. From a point west of Portage 

 came reports of considerable damage to a grove of young poplars. 

 No specimens were sent, but the description given seems to indicate 

 the Willow-grove Plant-louse, Melanoxantlius salicis, Harr., or a 

 related species. 



The Cock's-comb Elm Gall-louse (Colopha ulmicold, Titch.) 

 was extremely prevalent on elms throughout the city of Winnipeg 

 this season.
