THE ENTOMOLOGIST. 177 
been describing the extent and terrible results of this year’s 
plague of locusts in the Western States 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 came in during the 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
