The occurrence of the grasshopper at times in all agricultural districts in America is very different from the grasshopper or locust plague which we are describing.
The red-legged Caloptenus or the Rocky Mountain locust are provided for lofty flight and pass in myriads over the prairies, lighting whenever a cloud obscures the sun.

At one time the writer saw them in such hordes that they were found from Winnipeg to Edmonton, over a region about one thousand miles in breadth.

In that year they devoured not only crops and garden products but almost completely ate up the grass on the prairie to such an extent as to make it useless for hay.

In the year 1875 they appeared, in the main, for the last time in Manitoba, and in that year their disappearance was as sudden as in the former case of 1821.

Under the wing upon the body of each grasshopper was to be found one or more scarlet red parasites which drew all the juices from the body of the insect and produced death.
