NOTES ON THE RECENT OUTBREAK OF DISSOSTEIRA LONGI- 
PENNIS. 
By E. A. PoPENOE, Manhattan, Kans. 
| Secretary’s abstract. ] 
July 10 to 19 the author visited the northern part of Lincoln County, 
Colo., on account of newspaper reports of the stopping of trains by 
grasshoppers. He found a strip of country 16 by 25 or 30 miles in 
extent fairly covered with locusts, which proved to be Dissosteira lon- 
gipennis, a western isotype of the eastern D. carolina. They were con- 
gregated especially in the boundaries of this area. The country is 
poor and planted here and there to Corn and Sorghum, and there are 
occasional patches of garden vegetation. The season has been favora- 
ble and cool. The locusts are said to have come in swarms from the 
South last fall and to have settled along the Big Sandy Creek in a patch 
two or three miles in circumference, in which they layed their eggs in 
great numbers. Upon hatching this spring the young spread outwards. 
At the time of his visit in the northern part of the strip the insects were 
in the last larval and pupai stages, with very fewimagos. At the south 
line, however, the winged individuals were very abundant and flew like 
birds. The young hoppers had the habit of crawling up the side of 
buildings for a few feet, presumably for warmth. They were not 
strictly confined to roads, but traveled over bluffs and rounded hills, 
eating the buffalo and gramma grass. The winged individuals flew 
always to the south, but the others spread regularly outwards in all 
directions. The line of march was quite visible at some distance on 
the hillsides, and sheep-growers had to change the localities of their 
flocks. In marching, as a general thing, they preferred to follow the 
roads, moving quite rapidly, about 1 mile in 6 hours for 6 or 8 hours in 
a day only. They are credited with all the destruction which has been 
done by all kinds of insects, and he thinks that they did but very little 
damage to potatoes and corn, although marching through the fields in 
great numbers. At the time of his visit they were marching through 
wheat fields in the same way, but since he left they have done some 
damage to this crop. Many dead ones were noticed in one locality, 
but no signs of parasitism were found. It is supposed that they were 
destroyed by hail. In his opinion the ingect occurs generally upon 
low ground rather than upon high ground. 
Mr. Bruner said that this species is very seldom found below 3,000 
feet or above 5,500 feet elevation: It occursin Nebraska, Kansas, Col- 
orado. Wyoming, and northeastern New Mexico. It preferably locates
