North Dakota. F. G. Butcher (July IS): Grasshoppers continue to be the 
most important insects in all counties, except in the northeast 
corner of the State, with M. mexicanus the predominant form. Most 
of the important species are in the adult stage. Localized mi- 
grations have been commonly reported during the last 2 weeks over 
most of the infested area but the hoppers have not spread out ex- 
tensively into noninfested areas. Control operations are slowing 
down considerably in some areas, since farmers are becoming dis- 
couraged because of the continued invasion by adult flights. M. 
bivittatus Spy, M. packardii Scudd. , M. mexicanus , and M. femur - 
rubrum Deg. have been observed mating and M. bivittatus has started 
laying eggs. 
South Dakota. H.. C. Severin (July 2): Many grasshoppers are now fully 
winged. Considerable migration is taking place. Hordes of grass- 
hoppers are moving into South Dakota from the south and many are 
leaving the State for regions elsewhere. Owing to harvest, the 
poisoning campaign has lagged. (July 3) : M* mexicanus is the 
species most harmful in South Dakota. Of considerable less im- 
portance are M. differentials and M. bivittatus . A very serious 
infestation covers much of eastern South Dakota, east of the 
Missouri River. Much less serious west of the Missouri, but become 
more abundant near the Black Hills. Considerable damage has alr§ady 
been done to small grain, corn, and garden crops. 
Nebraska. 0. S. Bare (May 20 to July 20): Grasshoppers proved to be 
the outstandingly major pest in the State during the period here 
covered. The grasshopper infestation is unquestionably the heaviest 
and most widespread since the pioneer "grasshopper years" of 187*+- 
76. Every county in the State has experienced serious crop damage, 
with the possible exception of five or six counties in the sandhill 
area, and more or less scattered but somewhat destructive infesta- 
tions have occurred there. M. bivittatus and M. mexicanu s had 
hatched in large numbers by May 20, and hatching of those species 
continued into the early part of Juno. M. different ialis had barely 
started to hatch on May 20, but developed rapidly and continued well 
through June. The first noticeable crop damage was reported about 
May 20, and became increasingly heavy throughout the 2-month period. 
Spring seedings of alfalfa and clovers were badly damaged or destroyed 
and spring-planted grains and older alfalfa and clover fields in many 
sections were badly stripped. Serious damage to corn began early in 
June and has continued to the close of the period covered by this 
report. 
M. H. Swenk (July 20): Po.rasites of grasshoppers have begun to 
appear in force. The amount of parasitization by the sarcophagid 
fly Sarcophaga kellyi Aid. had by July 20 become quite large. Dead 
M. bivittatus , M. different ialis , M. femur-rubrun , .and M. mexicanus , 
collected from two farms near Lincoln from June 25 t^> July 1, began 
giving up maggots of this species within 2U hours. Of the 691 grass- 
hoppers collected on one farm, a total of 125 sarcophagid noggots
