“ Fayette Co., Central Texan, about Oct., 1867. — Grasshoppers appeared in this neigh¬ 
borhood on the 3rd instant in great numbers.” —Ibid., p. 365. 
“ Austin Co., Central Texas, about Nov., 1867. -Grasshoppers, hitherto unknown in this 
locality, have appeared in countless numbers.” Ibid., p. 365. 
In the following Table will be found a chronological synopsis of the various Grass¬ 
hopper-invasions, of which the details have been given above. In every case eggs were 
deposited in the ground in great numbers, which, so far as can be ascertained, hatched 
out in the following spring, so as to cause considerable damage to the crops.

The true Hateful Grasshopper must be carefully distinguished from the common Red- 
legged Grasshopper ( Caloptenus femur-rubrum, DeGeer,) which swarms everywhere from 
Massachusetts to Minnesota, and from Pennsylvania to Illinois. The unpractised 
observer, indeed, would very readily confound the two species ; for in reality they differ 
in nothing but the comparatively much longer wings of the former, which enable it to 
fly vast distances ; whereas the latter does not usually fly more than a few yards at a 
stretch. Harris reports of the Red-legged Grasshopper, (or, as he prefers to call it, ‘ ‘ the 
Red-legged Locust,”) that in certain seasons it almost entirely consumes the grass of 
the New England salt-marshes, and then emigrates on to the uplands, devouring on its 
way grass, maize, garden-vegetables, potato-tops, clover and tobacco-plants. “ These 
insects,” he continues, “ will even destroy in a few hours the garments of laborers, hung 
up in the field while they are at work; and, with the same voracity, they devour the 
loose particles which the saw leaves upon the surface of pine-boards, and which, when 
separated, are termed saw-dust.” (Inj. Ins., pp. 168-170.) As the reader will have 
noticed, the Rocky Mountain species has the same omnivorous propensities. It is prob¬ 
ably to this Red-legged Grasshopper that Mr. S. T. Kelsey, of Kansas, refers, wnen he 
says that he “ has known Grasshoppers in western New York to destroy a large propor¬ 
tion of the growing crops, and then deposit their eggs,” as the other species did m 
Kansas in 1866. (Prairie Farmer, June 15, 1867.) While I was attending the State Fair 
held at Freeport in North Illinois in the year 1859,1 heard (as I have already recorded 
elsewhere) from the farmers of that neighborhood great complaints of the damage done 
them that year by Grasshoppers. And Mr. Arnold, of DeKalb County, which also lies 
near the northern boundary of this State, says that his oat-crop in 1861 wa» dmums ice 
at least 10 bushels per acre by the Grasshoppers, who ate off the heads, the ground being 
literally covered with grain.”* In Fulton Co., Central Illinois, ‘ myriads o young 
grasshoppers ” are reported to have appeared “ in the meadows, so as to be Lke y o 
destroy the crop of clover seed,” on June 23, 1860. (Prairie Farmer, July 5, I860. 
And in Champaign Co., Central Illinois, young grasshoppers are said to have swarmed 
” in countless multitudes” in the middle of June, 1861. (Ibid, Jum 20,1861.) All these 
grasshoppers in North and Central Illinois were also, in all likelihood, the common
