is that in Ephestia the palpi are erect while in Plodia they are porrect. 

 The criticism concerning the larva shown at fig. 30, Vol. II, is equally 

 unfortunate, as we have carefully studied the early stages ofinterpunc- 

 tella and are equally familiar with those of Oelechia cerealella, the early 

 stages of both species being represented in large series in the National 

 Museum collection. 



REPORT ON A LOCAL OUTBREAK OF GRASSHOPPERS IN IDAHO. 



By Lawrence Bruner. 



Lincoln, Nebr,, September 1, 1890. 

 Prof. C. v. Riley, 



U. S. Entomologist, Washington, D. C: 

 Sir: I submit herewith a brief report on my recent trip into the Northwest, for the 

 purpose of investigating the reported locust or grasshopper plague in portions of 

 Idaho, Montana, and Utah. The trip was made in company with Mr. T. H. Marsland, 

 of this city, who acted as an assistant while in the field. 

 Respectfully, 



Lawrence Bruner, 



Special Agent. 



We left Lincoln on the 7th of August and proceded to Soda Springs, 

 Idaho, where the first stop was made. Here inquiry was made of the 

 settlers as to any possible locust depredations within that immediate 

 vicinity or in outlying regions. The country round about was also vis- 

 ited by us, and careful collections made of such locusts and other in- 

 sects as were to be obtained. After three days had been spent in this 

 work, and no locust plague discovered east of the Utah and Northern 

 Eailroad, either through report or by actual observation, we proceeded 

 to Pocatello, Idaho. Here we remained a day, busying ourselves in 

 interviewing various persons belonging to the immediate locality, as 

 well as others who lived in Montana and other portions of the North- 

 west. Collections were also made in the valley of the Portuuff and 

 among the foot-hills adjoining, but none of the destructive locusts were 

 obtained. 



During the day spent here a miner from Butte, Mont., was inter- 

 viewed, who informed us that several weeks previously he had seen 

 large numbers of grasshoppers in the vicinity of Red Rock Lake, Mon- 

 tana, and Henry Lake, Idaho, but was not certain as to the kind. His 

 description of the insects, however, lead me to believe they were 

 " natives," and not the much-dreaded Rocky Mountain Locust. 



From Pocatello we proceeded westward to Shoshone, Idaho, the near- 

 est point on the Oregon Short Line of the Union Pacific Railway, to the 

 Camas Prairie of Logan County, Idaho, and where we had become 

 pretty well satisfied the grasshoppers of which we had come in quest 

 would be found. Upon arriving at Shoshone we accordingly began 

 immediately to investigate, and soon found a number of specimens of
