222 THE CANADIAN NATURALIST. [Vol. Vlil. 



McKenzie says it is reported that eggs were deposited west of 

 Manitoba Lake, about one hundred miles north-west of Burnside. 



Portage la Prairie, Man. (C. Mair, J. Cowan, M.P.P.) 

 Produced here from the egg, hatching from the middle of May 

 to middle of June. Began to leave about middle of July, going 

 south-east. Winged swarms passed overhead from the latter 

 part of July till the middle of August, coming generally from 

 the south-west and going south-east : few alighted. Two-thirds 

 to four-fifths of crop destroyed. In Portage la Prairie, Electoral 

 Division, about 12 miles square, the grain crop should have been 

 200,000 bushels; 40,000 bushels actually harvested. In High 

 Bluff Electoral Division, loss greater in proportion, only 10,000 

 bushels of grain saved and a half crop of potatoes. Mr. Cowan 

 writes that some winged swarms appeared from the south early 

 in June, long before those hatched here could fiy. 



High Bluff, Man. (J. A. K. Drummond) Produced here 

 from the egg, hatching May 15th to June 15th. Left about the 

 middle of July, going for the most part south-east. A winged 

 swarm arrived from the west July 19th, and swarms continued 

 arriving from this direction, and departing, generally south east- 

 ward till the latter part of August. Greater part of crops de- 

 stroyed. No eggs deposited. 



Gladstone, Man. (C. P. Brown.) Produced here from tfye 

 egg, hatching June and July. Left about the last of August,, 

 going south-eastward. About July 17th a few winged swarms 

 arrived from the west, leaving in same direction as those pro- 

 duced here. Crop, amounting to from 20,000 to 30,000 bushels 

 destroyed. No eggs deposited. 



Poplar Point, Man. (L. W. McLean.) Produced from the 

 egg, hatching from the 20th of May till the 10th of June. 

 Took flight about the 2nd of July, and continued flying till the 

 10th of August or thereabout ; went south-east. Some swarms 

 seen on the wing at dates above given were supposed to have 

 hatched in the western and north-western parts of the province, 

 or beyond the province line. These appear to have mingled 

 with those produced in the locality itself, in their flight. Only 

 crops planted, potatoes, which generally gave pretty good re- 

 turns. No eggs deposited.
