: GRASSHOPPERS (Acrididae) 
Illinois. W. P. Flint (June 13): Grasshoppers have "been hatching for the past 
two weeks in central Illinois. They are slightly more abundant than last year. 
Wisconsin. C. L. Fluke (June 19): Grasshoppers are very abundant. 
Minnesota. A. G. Haggle's r ( June 26): Fifty-five counties are organized for control. 
Control has been perfect. 
North Dakota. J. A. Munro (June 15): Grasshoppers are generally prevalent over 
the areas indicated by the 1S32 Federal survey. The situation is very serious 
in the southwestern counties and a few of the north-central counties. 
F. D. Butcher (June 12): Hatching in the ..-astern and northern parts of 
State seems to be almost over. I find a few fourth-instar Melanoulus bivittatus 
Say now, but most of them are younger. Rains of the last ten days, which have 
been intermittent, are responsible for destroying a few of those which had been 
out only a few hours. (June 20): There has been no material change in the 
situation in the State during the past week. All the eggs except possibly 
those of M. dif ferentialis Thos. have hatched. The hatching period has been 
of shorter duration than it was a year ago. Very high temperatures the last 
few days of last week brought many hoppers from the roadsides into the fields. 
(June 21): I saw my first adult M. bivittatus today. E. L. Shotwell reports tb» 
on June 19 he- saw one adult and one f irst-instar nymph near Dickinson, Stark 
County. He also reports seeingan adult M. mexicanus Sauss. on June 15. 
South Dakota. H. C. Severin (June): Grasshoppers are very abundant, chiefly M. 
differentialis , M. bivittatus , and M. mexicanus , but not so abundant as in 1931. 
Iowa. C. J. Drake (June 19) : Grasshoppers have appeared in destructive numbers in 
Woodbury and Plymouth Co\mties, in areas not poisoned last year. M. 
differentialis and M. bivittatus are the principal species involved. 
Nebraska. M. H. Swenk (May 20 - June 20)': Grasshoppers wore hatching in southern 
Nebraska by May 13, but not in the large numbers in which they appeared in 1930, 
1931, and 1932. However, in northern Nebraska, grasshoppers have again ted 
out in the same large numbers as during the past three springs. They became 
much in evidence in the pastures and small grains about June 1, and a week or 
ten days later it became evident that very serious damage to the corn was 
impending. The chief species concerned were M. bivittatus , M. dif-\.:v:-.:ia.lis , 
and M. femur-rub rum DeG. , though there were also ■'unusual numbers of adults of 
Parciclophora ( = Kippiscus ) ha.ld e mar.il Scudd. and P. a.piculata Say as well as 
nymphs of Arphia sp. On June 13 the M. bivittatus nymphs were mostly in the 
third instar, while those of M. differential is wore mostly in the second 'instar. 
Some M. femur- rub rum were adult. Several carloads of poisoned-bran bait were 
shipped into this section about the middle of June. 
Kansas. H. . R. 3ryson (June 22): Grasshopper's are more plentiful at Manhattan this 
year than last. Reports have been received from Madison and. Grenola. M. 
bivittatus' is 'the most numerous.
