under surface, of elongate form, when full grown measuring three- 

 eighths of an inch in length; widest at the middle, and tapering 

 toward either extremity. Many larvae are frequently found together 

 on a single leaf, where they eat the upper surface, doubtless because 

 the lower surface of the leaves of the natural food plants rest on 

 the water. As a result of these attacks the leaves become broAvn and 

 unsightly. The white lily is less aifected than yellow lilies. 



As to remedies, the arsenicals are quite effective, and Paris green 

 is reported by Mr. Sudworth as checking the ravages of the beetles 

 on willow. ^Vhen spraying bean plants, arsenate of lead is prefer- 

 able, owing to the danger of scalding the more tender leaves if 

 Paris green is used. AVhen this species occurs in troublesome num- 

 bers on aquatic plants it might readily be destroyed in all stages, 

 and especially as larva, if the ponds, fountains, or other places in 

 which the lilies are growing could be flooded so as to bring the 

 insects to the surface. A few drops of kerosene spilled on the water 

 would then destroy the floating insects. 



GRASSHOPPER CONDITIONS IN NEBRASKA, NORTHEASTERN COL- 

 ORADO, WYOMING, MONTANA, AND WESTERN KANSAS DURING 

 THE SUMMER OF 1904. 



By Lawrence Bruner, Tcmporaru Field Agent. 



In compliance with instructions received last July, the writer spent 

 the greater portion of the month of August in endeavoring to ascer- 

 tain the existing status of the grasshopjoer, or locust plague, through- 

 out the region lying to the east of the main divide of the Rocky 

 Mountains and west of the Missouri River. In order to accomplish 

 this work in a satisfactory manner several journeys were undertaken 

 over the various lines of railroads located in the region under inves- 

 tigation. The officers of all of these roads cooperated in the work 

 by kindly providing all transportation necessary for visiting the 

 various localities known to have been infested by these insects during 

 recent years. 



In order to ascertain more clearly the conditions in Colorado, the 

 entomologist of the State Agricultural College, Prof. C. P. Gil- 

 lette was consulted. Visits were also made to the Agricultural 

 College of Montana and to the State University of AVyoming, where 

 important data bearing on the subject imder investigation were 

 obtained. Some additional records of grasshopper abundance were 

 gathered from the daily press reports, while data l^earing on the 

 presence of locusts in other localities not visited were gleaned from 

 various persons. 



By carefully arranging and studying all the information accumu- 

 lated it would seem that the general status of the locust pest, over
