 Gnathotrichus), found in the United States. 



Grasshopper report for 1895, L. Bruner (pp. 31-35). — A brief account 

 of an excursion into Colorado and the Northwest to investigate the locust 

 conditions of those regions. In the neighborhood of Denver, Golden, 

 and Fort Collins the most abundant insects observed were Melanoplus 

 bivittatus, M. atlanis, M. fa&dus, M. packardi, and Di&so&teira longipen- 

 nis. The damages caused by these locusts, though comparatively 

 light, were sufficient to warrant the settlers in taking decisive action. 

 Numbers of the insects were attacked by Empusa gryllce. To the heavy 

 rains which were followed by a rank growth of vegetation the author 

 attributes the bunching and the eastward and northward spread of the 

 long-winged species. Between Cheyenne, Wyoming, and Oreno Junc- 

 tion, Wyoming, where the hoppers had been particularly numerous in pre- 

 vious years, few were found, in consequence, apparently, of a series of 

 cold rains during the months of May and June. Near Laramie ( Jity ( ■am- 

 nula pellucid a was found very abundant in places, but the other species 

 were not present in even moderate numbers. North of Ogden the most 

 numerous species were Melanoplus bivittatus and M. atlanis. In some 

 places Gamnula pellueida was present in more than ordinary numbers. 

 At Logan most of the commoner species were abnormally abundant. 

 At Pocatello, Idaho, slight indications of locusts were noticed. Along 

 the Snake River and thence to Colfax, Pullman, Moscow, Lewiston, 

 and Waha, they were found to have done more or less injury and in 

 many places were still active. Among the species observed were 

 Melanoplus femoratus, M. foedus, M. atlanis. Gamnula pellueida, and 

 JHssosteira oblitera ta . 



As a result of his observations the author concludes this year was 

 one of unusual drought for this part of the country, and that, as the 

 grass on the hillsides and in the pastures was shorter than usual and 

 consequently sooner grazed off by the stock, the hoppers were forced 

 to move to cultivated grounds; and, taking the region as a whole, con- 

 siderable damage was done, although no single district may be said to 

 have been completely devastated. The hoppers appear to be on the 

 increase, but there is no apprehension of an invasion from the Eocky 

 Mountain locust at any point, although there may, and probably will, 

 be local outbreaks of native species. 



Grasshopper report for 1896, L. Bruner (pp. 36-39). — This records a 

 journey undertaken to investigate reports of grasshopper injuries in 

 Nebraska, Dakota, Kansas, Minnesota, Iowa, and Colorado. Some of 

 the early reports were found to be largely caused by Melanoplus spretus. 

 Later reports from north of the Platte River were found to be caused 

 by the long-winged plains locust, Dissosteira longipennis. Investigation 

 showed the insects were not in such numbers as to cause great injury 

 except in isolated districts. The other species found to be destructive 

 in Nebraska and adjoining States were Melanoplus atlanis, M. femur- 

 rubrum, M. bivittatus, M. differentialis, and M. lalinus. M. atlanis was
