THE ENTOMOLOGIST. 177 



been describing the extent and terrible results of this year's 

 plague of locusts in the Western Stales of the Union. We 

 have now, unhappily, to record its occurrence in our own new 

 province of Manitoba, which adjoins the state of Minnesota, 

 so frequently referred to above. From the following record 

 of visitations previous to this year, it will be observed that 

 they were, in almost all cases, simultaneous with those in the 

 neighbouring States, that we have described in the earlier 

 part of this paper. For this record we are indebted to the 

 letter of the Winnipeg correspondent of the Toronto ' Globe,' 

 which appeared in that paper on the 5th of August last: — 

 ' Grasshoppers first appeared in Red River towards the end 

 of July, 1818, six years after the commencement of the 

 settlement. They covered the settlement belt, but did not 

 utterly destroy the wheat crop, it being nearly ripe at the 

 time. Barley and other crops were swept away. They 

 deposited their eggs and disappeared; and the following 

 spring the crop of young grasshoppers was immense. These 

 departed before depositing their eggs, but devoured all vege- 

 tation on their route, thus destroying all the crops of 1819. 

 Greatnumbers camein duringthe season of 1819, and deposited 

 their eggs ; so that in 1820 the crops were again all destroyed. 

 Thus for three successive years were the crops in this country 

 destroyed by these pests. They then disappeared for thirty- 

 six successive years, the next visitation being in 1857, when 

 they visited the Assiniboine settlement, doing but little injury 

 beyond depositing their eggs. The following season their 

 progeny destroyed all the crops within their reach. In 1864 

 they again appeared in considerable numbers, but did little 

 injury to the wheat crop. The following year the young 

 grasshoppers partially destroyed the crops, leaving many 

 districts entirely untouched. The largest swarm ever known 

 came in August, 1867, but the crops were so far advanced 

 that season that they did but little injury. Their eggs 

 produced such immense swarms the following spring that 

 they destroyed everything that had been sown throughout the 

 settlement, and famine ensued. In 1869 they again visited 

 the country, but too late to do much harm. The season 

 following, however, they destroyed most of the growing crops. 

 In 1872 immense hordes of these winged pests again visited a 

 part of the country about the beginning of August. The
