3 miles wide and had about 15 hoppers per square yard; still another was 
■observed in Seward County. First copulation of A, turnbullii was 
observed in Clark County on June 5» ^^id half-developed eggs are now to be 
found in some females* (June l6 to 22): Most of the M, diff erentialis 
are in the third, fourth, and fifth instars* 
Nebraska, (June 2-8); Gravid females of A. turnbullii and M. confusus were 
reported as present in the Republican Valley on June 6, The degree of 
hatch is as follows: M, confusus , 9 ^ to 100 percent; M. mexicanus , 95 to 
98 percent; M, bivittatus , 90 to 9^ percent; M, differentiali s , 40 to 75 
percent; and A. turnbullii , 90 percent. Very little population dispersion 
has occurred to date, and damage has been confined to weeds along road- 
sides and field margins. Only a slight amount of small grain and other 
crop dacaage has been recorded and amounts to less than 1 percent. The 
first adults of M. packardii were observed on June l4 in the Republican 
River Valley east of Benkelman. M, confusus was first observed mating 
near Websterville, in Custer County, on June 10* (June l6-22); In the 
northeastern part of the State, M, bivittatus is the dominant species with 
M. differentialis being almost as numerous. The hatch of both these 
species is complete except in the eastern Missouri River Counties where a 
few M. differentialis remain to hatch. Approximately 2 percent of the 
M, bivittatus are now adult. In western Nebra.ska, M. packardii in the 
fourth instar is the dominant species, M, bivittatus and M. mexicanus 
are principally in the third and fourth instars with a few of the latter 
being adult, M. confusus is adult in all portions of the State, Little 
movement into fields has been noted and' crop damage has not been extensive 
in any area, 
Missouri. (June l6 to 22): Only a few first and second instar nymphs of 
M. bivittatus , M, mexicauus , and M. differentialis have been reported in 
the State. Populations approaching 50 per square yard have been observed 
on field borders. Injury has been limited to barley, garden crops, and red 
clover, 
Iowa, (J\ine 2-8): Heavy rains during the last week in the western part of 
the State are reported to have reduced populations slightly in a few 
areas. In the northwestern border counties the hatch of M. bivittatus 
is about 70-percent complete, and marginal populations average from 100 
to 150 per square' yard. Sioux and Plymouth Counties are the most seriously 
infested, (June 9“I5)s M* bivittatus and M« mexicanus have nearly com- 
pleted hatching in the northwestern part of the State, The early instars 
of M, differentialis have been noticed in much of this area. There has 
been a rapid increase in populations, owing to warm weather, 
Wyoming, (June 2-8): Hatching of M. mexicanus , M, bivittatus , and M. packardii 
is reported to be practically complete in Goshen, Platte, and Laramie 
Counties, No heavy infestations are reported in the above counties, while 
in Crook, Weston, and Campbell Counties, the infestations are reported to 
be even lighter. Hatching of K, differentialis and M, femur- rubrum is 
ej^ected to be completed within the next week, M, confusus adults are 
reported, (June 9-15)! Hot weather during the week has been responsible
