county, June 17, and twenty-four miles more easterly on the 21st. 
They appeared about noon, on days of sunshine, high in the air, seeming 
in the sunlight to be of asilvery hue, their wings light brown. At first 
scattering widely, the second day at noon they appear in immense num- 
bers, filling the air even to the ground. Gardens are first attacked, 
onions and cabbages fall before their ravages in the beginning, and, fol- 
lowing, all tender plants, even tobacco and wormwood; next barley and 
wheat, the leaves of which they strip in patches. About the fourth 
day, increased in numbers, they make a united attack on nearly all kinds 
of grain—seeming to leave corn and peas comparatively undisturbed. 
About the seventh or eighth day they begin to rise, and, if the sun is 
warm and the weather clear, leave finally about the eighth or ninth day 
about noon. Millions of these insects may at that time be seen flying 
in the air in the wind direction. They began toleave Martin County on 
June 29, and four or five days had elapsed before all had gone. They 
injured but did not destroy the wheat-crop, some pieces being left al- 
most unmolested, while others were badly stripped. Vegetable-gardens 
are generally ruined. <A tract of two thousand acres of beans, planted 
by a company consisting of three Englishmen, who broke the prairie, 
has been to the extent of nearly three-fourths devasted by grasshop- 
pers. 
Our correspondent in Faribault states that the insects had just reached 
the west line of that county, going east. They had laid their eggs in 
the counties westward, where they will hatch next spring, provided the 
conditions of incubation are not disturbed. é 
In Burt County, Nebraska, the young insects were hatched out in im- 
mense numbers. 
In Pocahontas County, Lowa, they appeared, in the fore part of. June, 
in an army thirty miles from front to rear, moving eastward on the 
ground till noon, when they took flight, flying very high. Their rear 
passed two weeks after their front had first appeared. They destroyed 
50 per cent. of the crops. In Emmett the barley was entirely destroyed 
and otber grains seriously damaged. Greater or less injuries are re- 
ported in Cherokee, Calhoun, and Woodbury. 
In Burt County, Nebraska, the young insects were hatched out in im- 
mense numbers too late for small-grain crops, but not too late for corn. 
They also appeared in Boone and Dixon in large force, where they de- 
posited their eggs and did much mischief, Our correspondent in Dixon, 
after careful examination, is satisfied that not over a third of the eggs 
deposited were hatched. They hatched out largely in Larmer County, 
Colorado. In San Luis Obispo, California, they were destructive on 
grain-crops, while in Fresno they were equally injurious to corn and 
cotton. 
Colorado potato-beetle, (Doryphora decem-lineata.)\—This insect is still 
developing eastward and northward. In New York it had appeared in 
four counties, viz, Wyoming, Niagara, Allegany, aud Chautauqua; in 
the latter it was quite mischievous. Pennsylvania received a more gen- 
eral visitation, not less than thirteen counties reporting the presence of 
these pests. They were very severe in Huntington, Fayette, Beaver, 
Jefferson, Crawford, Forest, and McKean; less serious damages are 
reported in Snyder, Cambria, Batler, Cameron, and Berks. In Elk 
County they attacked the early-rose potatoes which had previously been 
exempt from their ravages. In McKean the beetles appeared May 1, 
aud their young began to hatch out in the third week tollowing. The 
ravages of this beetle constituted almost the whole of the casualties to 
the crops from insect enemies in this State.
