PRESIDENT BARTON O. AYLESWORTH, A. M., LL. D. THE WESTERN CRICKET. (Anabrus simplex Hald.) LIFE HISTORY AND REMEDIES. BY C. P. GILLETTE. This so-called cricket, which is really a grasshopper with very short wings, attracted attention as an injurious insect in Colorado for the first time last year. The insect is not in any sense new, for it was here long before any white man set foot upon American soil. This grasshopper and its habit of marching in great armies have been written about for more than 50 years.* Judging from many published reports, this insect occurs in greatest numbers over the sage brush plains and hills drained by the Snake river and by Great Salt Lake, in Southern Idaho, and Northern Nevada and Utah. The occurrence of large swarms of the "crickets" in Southwestern Wyoming or Northwestern Colorado is not common, to say the least. Where it was most numerous in Routt county the past summer in the vicinity of Eddy, Dunkley and Hayden, the ranchmen declared that the visitation of the past two or three years in that region is the first in the memory of the oldest inhabitants. Such an unusual invasion is not likely to continue through many years. When the seriousness of the Routt county invasion became known to this office, Mr. S. A. Johnson started on an overland trip through the infested area to learn as much as possible of the migrating habits and the past history of this insect, and the writer went directly to Steamboat Springs, Eddy and Dunkley to study the habits and possible remedies where some of the worst injuries were: being inflicted. I was fortunate in falling into the hands of Mr.. John A. Whetstone and Mr. W. W. Miles of Eddy, who showed me: Some of the more important publications upon this insect are Stansb..
