West Lynne, Man. (H. Gr. Lewis.) Produced here from the 

 egg, hatching about the 20th of May, and leaving southward 

 toward the end of July. Swarms are said to have arrived from 

 the south, and to have left again going southward, about the date 

 last given. Two-thirds of crop destroyed. No eggs deposited. 



Selkirk, Man. (A. A. Koss.) Produced here from the egg, 

 hatching from the 10th of May, till the 10th of July. Left in 

 latter part of July, going south-eastward. A few swarms arrived 

 on the wing and alighted on the 29th of July. These left with 

 those produced in the district. Scarcely any grain sown. Pota- 

 toes put in late, were harvested without much damage. No egg 

 deposited. 



Winnipeg, Man. (Wm. Hespeler, F. Cornish, C. Inkster.) 

 Produced here from the egg, hatching during latter part of May 

 and first of June. Began to leave in second week in July, going 

 as a rule south and south-east. Winged swarms from the north- 

 west observed about the middle of July; generally passing over- 

 head without alighting. Flew in same direction with those 

 hatched here. Little crop put in, and more than three-fourths 

 of that destroyed. No eggs deposited. 



St. Boniface, Man. (Hon. M. A. Girard) Produced here 

 from the egg, beginning to appear in May. Left during August,

 part passed overhead going north and east. Few eggs deposited. 

 Twenty-four twenty-fifths of crop destroyed.

 the end of August, going south-south-east. Some swarms ar- 

 rived on the wing about the 15th and 20th of June from the 

 north-westward, and left at about the same time, and in the 

 same direction, as those produced here. All crops, save a few 

 fields of pease, destroyed. Eggs deposited during the summer 

 but young insects hatched and destroyed by frost.
