DESTRUCTIVE LOCUSTS OF NORTH AMERICA, TOGETHER WITH 
NOTES ON THE OCCURRENCES IN 1891. 
By LAWRENCE BRUNER, Lincoln, Nebr. 
In introducing this subject it is my intention to speak shortly upon 
the various species of locusts which have appeared in injurious num- 
bers within the limits to be designated with each species. Some of 
these species have covered a vast area of territory and have caused 
extensive injury from time to time, while others have appeared over 
limited areas and have caused but slight injuries; yet these injuries 
have been sufficient to necessitate their mention among the destruc- 
tive species of the country. Taking them all together we have exactly 
twelve destructive locusts within the territory designated. 
Selecting the species as they occur to me, I will mention first the 
Long-winged Locust, Dissosteira longipennis. During the early part of 
July reports came from the eastern and southeastern portions of Colo- 
rado of locust depredations. The first of these was that trains had 
been stopped by grasshoppers getting on the rails of the Santa Fé 
Railroad 100 miles or thereabouts east of Denver. Shortly after this 
reports appeared in the newspapers of serious damage being done 
around the point where they were first mentioned as stopping trains. 
About this time other reports of depredations came in from North 
Dakota and Minnesota and other portions of the West and Northwest. 
On the strength of these reports Professor Riley instructed me to visit 
the localities for the purpose of ascertaining the extent of country over- 
run, the actual and possible future injury which might result, and the 
exact identity of the species concerned. Being a Nebraska man and 
looking out for first interests, I naturally went to Colorado, the nearest 
locality to my home from which reports had been received. I first vis- 
ited Akron, Colorado, the nearest point on the Burlington and Missouri 
line to the region infested. There securing a team and driving to the 
south only about 6 miles, the advance guard of the enemy was en- 
countered. Imagine my surprise at finding here an entirely new insect 
as far as destructive locusts are concerned. Here in Colorado, and in
