(Juno 27) : Possible flight threats from M. mexicanus recently reported 
in Montana not extensive, as weather conditions have forced the hoppers 
to the ground. Most of remaining populations now reaching the adult 
stage and flight anticipated if weather conditions are favorable. 
Very serious problem found in northern Custer, Roosevelt, western 
Prairie, and southern Garfield Counties, Mont., as crops and range 
in that area have been almost completely destroyed and minor flights 
are originating in some sections. High populations of M. mexicanus 
and D. longipennis recently observed south of the Missouri River in 
South Dakota. Control operations started. 
Indiana. J. J. Davis (Juno 21): Young grasshoppers observed as abundant 
in clover and waste land. Expected to be abundant in some parts of 
the State but perhaps not a severe general outbreak. Reported on 
June 11 as damaging flowers in Howard County. 
Illinois. W. P. Elint (June 20): Reduced by heavy rains, which have 
favored growth of vegetation, further tending to lessen damage. 
Minnesota. A. G. Ruggles and assistants (Juno 19) : Infestations scattered 
over the State; more in the western counties than in the eastern. 
Heavily infested counties as follows: Anoka, Becker, Beltrami, 
Carlton, Clay, Dakota, cast Otter Tail, Kittson, Koochiching, Lac 
qui Parle, Morrison, Mahnomen, Pine, Pipestone, Rod Lake, Rock, 
Wadena, Wilkin, and Yellow Medicine. Chortophaga viridifasciata Deg. 
reported from McIntosh on May 5» when third-instar nymphs moderately 
abundant. Reported from Anoka on May 15, where the pink form was 
moderately abundant. Two- striped grasshopper, M. bivittatus Say, 
very abundant at Hallock, Kittson County, on June Uk 
Iowa. H. E. Jaques (June): Heavy infestation throughout western Iowa, 
becoming lighter in the central comities. Scattered light infesta- 
tions in extreme southeastern Iowa. 
Missouri. L. Haseman (June 24): Adults of M. bivittatus began appearing 
in central and northern Missouri around the middle of June. M. 
mexicanus ready to oviposit in central Missouri. M. diff orentialis 
Thos. still immature and less abundant than the other two species. 
Heaviest infestation again centers in a dozen north-central counties. 
North Dakota. J. A. Munro (June 22): Unusually heavy infestations, with 
M. mexicanus predominating, observed in brush or wooded areas along 
rivers and streams. Control difficult. Control work going on mainly 
in the Red River Valley end western counties, whore infestations are 
most serious. 
South Dakota. H. C. Severin (June 5) : M. confusus Scudd. has increased 
in abundance during the last few years until it has become very 
injurious all over the State.
