224- 
Minnesota, '(June hatch of M, mezicanus , M, hivlttatus , and M. 
femur-ruhrum is reported to he from 50- to 50-percent Qompleted for 
the first two species, and about '5-percent completed for M* femur-ruhrum . 
The hatch of pellucida is reported to he -about 50-j-percent completed* 
In most counties M. femur- ruhrum is the dominant species* (June l6-22): 
M. mezicanus and M* hivittatus have nearly completed hatchijig in 
Kittson County. The latter species comprises about 70:p-ercent of the 
infestation and the majority of specimens are nov^r in the fourth instar 
with the last instar of M, hivittatus becoming common* In Polk County, 
M. hivittatus , M. mexicanus , M* f emur-rubrum, _C. pellucida , and 
Melanoplus packardii are the dominant species. JC. pellucida are found 
in the second and third instar while the remaining species are .mostly 
in the third and fourth. In the eastern four-fifths of this county, the 
hatch is about 6o percent complete* About 70 percent of the grasshoppers 
present in Marshall Coxinty are M, hivittatus ; M. mexicanus comprises 
about 20 percent of the infestation. The hatch is 90 to 95 percent 
complete. The majority of the njonphs are in the third and fourth 
instars with the.la.st instar of M, hivittatus becoming quite common. 
Throughout the remaining areas in the infested counties in Minnesota, 
the hatch varies from 20 to 80 pr 90 percent complete*. In most of 
these areas first and second instar JM* diff erentialis comprises the 
vast majority of the grasshoppers present. 
Wisconsin, (June 9-15) s Populations of M. hivittatus ranged from 15 to 35 pe* 
square yard in the infested counties in the State and are in. the first, 
second, and third instars* (June l6-22): No general hatch has occurred 
as yet in the .State, Most of the- hoppers present are in a sandy area 
south ".of -Wausau in Marathon County. Grasshoppers were found here to run 
as high as 60 to the square yard* M, hivittatus and M. femur-rubnim 
'.are' the only two species reported. Only about half of the- grasshoppers 
have hatched. 
Michigan. R, Hutson (June 22): M, mexicanus was about 85- to 90-percent 
hatched in Isabella, Clare, ”losco, Alcona, Alpena, Montmorency, and 
Oscoda Counties this week, .Prom 10 to 15 percent were in the first 
instar, from 5^ to 75 percent in second instar, and about 10 to .20 
■- percent were in the third instar, £, pellucida was found to be 
practically 100-percent hatched wherever found, -being mostly in the 
first and second instars, .All other specie,s were in about the same range 
of hatching development. .Small numbers of Ageneotettjx deorum Scudd, 
occurred on some sites, (June l6-22): .M, mexicanus constitutes about 
65 to 85 percent of the grasshopper populations in the infested counties* 
A* deorum is present in all coxmties except Iosco, Alcona, and Alpena, 
In the latter county, .only M, mexicanus is reported. In Iosco and Alcona 
Counties, C. pellucida is to be found, 
Illinois, W, P, Flint (June I9): Relatively scarce. No damage reported from 
any. section of the State*
