134 THE CANADIAN NATURALIST. [Vol. vili 



were very numerous and destructive, but he noticed that many 

 were attacked with a small red parasite. When mature, the 

 swarms went, in part at least, to the north ; and some were 

 stated to have deposited their eggs near Lake Winnipeg. Other 

 facts contained in Mr. Gunn's letter I hope to include in the 

 report for 1875. 



Stone Fort, M. — (W. Flett.) Appeared in swarms from the 

 south and south-west, generally departing easterly. Eggs depo- 

 sited, and some hatched in autumn. 



Cook's Creek, M. — (G-. Miller.) Not produced here from 

 the egg. Swarms appeared about July 26th from the north- 

 west. Remained about two weeks and departed south-eastward. 

 Many passed overhead without alighting. Crops about two-thirds 

 destroyed. 



St. Ann's, M. — (J. H. Stanger). Not produced from the 

 egg here. Swarms first seen July 22nd, and coming from west- 

 by-south. Continued arriving and departing for about two 

 months, some leaving in the latter part of September, but many 

 remaining till they died. The first swarms went from here east- 

 ward, the last more to the south. Eggs were deposited and some 

 were hatched in autumn. 



Barley, oats, potatoes and vegetables suffered most. Some 

 wheat escaped. Peas suffered least of all field crops.
