226 THE CANADIAN NATURALIST. [Vol. viii. 



Crookston, Minn. (E. M. Walsh.) A few locusts produced 

 here from the egg, hatching from May 15th to June 10th. 

 Left July 15th, going south and south-east. These did little 

 damage. Swarms appeared on the wing from the north, and 

 passed south-eastward, about July 20th. Crops not injured. 

 No eggs deposited. 



North -West Angle, Lake of the Woods. (M. M. Thompson.) 

 No locusts hatched here. Swarms arrived on the wing about 

 August first from the north-west, and left again about the 20th 

 of August, going south-east. Only crops put in potatoes, which 

 were nearly all destroyed. No eggs or young insects observed in 

 the autumn. 



Mr. Thompson writes that these notes will apply equally to 

 Broken Mead, White Mouth, and Birch River. These are 

 stations in the wooded district east of the Red River Prairie, 

 and on the road between Winnipeg and Lake of the Woods.
