the -two-striped and lesser’ migratory,’ an present in consid.erable num- 
bers in all of the counties in the western part of the State, border-

Michigan. R. Hutson (May 2l): M. nexicanus was hatching at Bridgman on 
May 7, and first and second instars of M. nexicanus , Cannula pollucida 
Scudd., and. Ageneotettix do 0 run Scudd, were observed, in Clare, Mont- 
calm, Isabella, Wexford, and Osceola Counties in the northern half of

Minnesota. A. G. Buggies (May 19 ) * Grasshoppers hatching generally in the 
northwestern part of the State, where a, 90-percent hatch has occurred. 
North Dakota. B. M. Gaddis and assistants (May 4-10 ) : M. bivittatus and 
M. nexicanus began hatching in favorable situations in eastern and 
south-central North Dakota during the week, (May 11-17)* Cool weather 
throughout eastern North Dakota retarded hatching during the week; 
however, the ha,tch is about 25 percent complete, with populations 
ranging from an occasional nymph to 15 per square yard along field 
margins, 
F. G, Butcher (May 23)1 Eggs are hatching generally throughout in- 
fested areas with most acute developments appearing in the northeastern 
counties , 
South Dakota. B. M. Gadd.is and assistants (May 4-1.0) 1 The hatch ranges 
from less than 5 percent in the northeastern part of the State to 20 
percent in the east-central portion, M, nexicanus , M, bivitt.atus , 
and M. confusus Scudd. are the predominant species. Populations on 
margins range from 5 to 35 per square yard. (May 11-17): A rapid 
hatching of M. bivittatus and M. nexicanus occurred in the State dur- 
ing the week. W Qa ther conditions were highly favorable for . egg and. 
nymphal development. In south-central South Dakota, the hatch of M. 
bivittatus and M, mexicanus is between 50 and 75 percent complete. 
Most of the grasshoppers are in the second instar, with marginal popu- 
lations of 100 to 125 per square yard. No appreciable hatch of M.
