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 longipermis. 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 F6 

 Kailroad 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 JSTorlh 

 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
