outbreak has been brought under control fairly well. In the north- 
western part of the State, where injury was most severe in 193&> 
grasshoppers have been less numerous than average, except in a few 
spots. Where injury has occurred, the destructive species have been 
M. differentialis and M. femur- rub rum . M. bivittatus , ordinarily 
regarded as an unusual species in northwestern Arkansas, has been 
abundant in a few spots, 
Oklahoma. F. A. Fenton (July 20): Grasshoppers continued to be the most 
injurious insect pest in Oklahoma during the past month. The most 
common species, M. differentialis , has now largely reached the 
adult stage and is prevalent in alfalfa and cotton fields. Most 
of the crops, with the possible exception of alfalfa, are beyond 
the point where they can be injured by these insects. 
C. F. Stiles (July 22): Grasshoppers continue to be very 
numerous in Oklahoma, except in the extreme southeastern counties, 
and in some localities there are outbreaks. Corn, cotton, and 
alfalfa are suffering most at this time. Many cornfields are 
being completely defoliated and the third cutting of alfalfa is 
being seriously damaged, where the hoppers have not been poisoned. 
The species doing the most damage are M. bivittatus , M. differen - 
tialis , and M. mexicanus . The species most prevalent in the western 
Panhandle counties is Dissosteira longipennis Thos. 
Alabama. J.. M. Robinson (July 21): In Jackson County grasshoppers were 
reported on July 17 as being a very serious threat to field crops. 
The bird grasshopper ( Schistocerca americana Drury) is causing 
serious concern at Deatsville attacking over 2 acres of cotton and 
about 1 acre of oat stubble. Adults vrere emerging on July 19* 
Mississippi. C. Lyle (July 2]>) : Schistocerca americana Drury was damaging 
corn and cotton at State College about the middle of July. It was 
necessary to use poisoned bait to control them. Infestations of 
grasshoppers have been found in Warren, Washington, and Quitman 
. Counties, attacking cotton and other crops. 
Texas. F. L. Thomas (July 23): Grasshoppers were damaging wheat on June 
26 and 27 in Hemphill and Ochiltree Counties. Fifty percent of the 
wheat heads were on the ground at Canadian in Hemphill County and 
also in Dallam and Sherman Counties, of the north Panhandle area. 
Idaho. C. Wakeland (July 2l): Small local outbreaks of grasshoppers are 
being baited in Bear Lake, Bannock, and Caribou Counties, south- 
eastern Idaho; in Fremont County, northeastern Idaho; in Lincoln 
and Gooding Counties, south-central Idaho; and in Payette County, 
southwestern Idaho. The population is increasing and we expect 
outbreak conditions in larger areas in 1938. 
Utah. G. F. Knowlton (July 29): Grasshopper conditions are becoming 
increasingly serious as late-hatched nymphs increase in size.
