does not predominate. As for M. different ialis Thos. , a very pe- 
culiar situation has developed in this State. The fall survey showed 
that eggs of M. d ifferential s and M. biv ittatus were present in 
nearly equal numbers in the heavily infested sections, and that the 
hatch of M. different ialis eggs, which occurred about two weeks later 
than that of the _M. bivittatus , was about as we expected. In fact, 
in many places there was a very heavy hatch of the latter species. 
At present, however, there arc very few M. d ifferentials hoppers in 
the State. V/hat has. happened to them is conjecture on our part. Ap- 
parently there has been some element in our very unusual weather that 
the young M. diff eren t ialis hoppors could not resist. 
Nebraska. M. H. Swenk (July 17): The grasshopper situation has con- 
tinued with unabated severity during June and up to the present time. 
About the same areas that showed a severe infestation by the middle 
of Juno -are now infested, and all the poisoned bran bait has been 
used that could be obtained through the Federal agencies. 
Oklahoma. C. 3T. Stiles (July 2.3): Grasshoppers are fairly numerous in 
some of the western counties, especially along roadways and fence rows, 
and in some instances have completely destroyed late-planted feed- 
stuffs, such as Sudan grass and grain sorghums. There are several 
species in the fields, but the yellow-legged grasshopper is the most 
prevalent in Kingfisher County. 
Montana. A. L. Strand (June 23): The grasshopper campaign is progressing 
satisfactorily in most counties. In areas where the hoppers were 
more abundant than was expected there is a shortage of bait. Over most 
of the State good crops have demonstrated that the poisoning of the 
grasshoppers was very much worth while. 
Wyoming. C. L. Corkins (July 26): We are now gradually briugi&g to a 
close the grasshopper control campaign which has been under way in 
20 of the 23 counties of the State. When the campaign is completed 
a little over 6,000 tons of dry bait will have been used. So far 
the injury to crops has been only about 1 percent, but most of the 
range area in the eastern part of the State has been severely damaged. 
Idaho. C. Wakeland (July 2h): The grasshopper control campaign is nearly 
at an end. Grasshoppers have not caused extensive serious injury in 
any but isolated small communities because a well-coordinated control 
campaign has been carried out, using Federal bait. Some injury is 
being reported by farmers in areas where grasshoppers are migrating 
into cultivated crops from adjoining range lands. These hoppers are 
in the adult stage and control is not so' satisfactory as earlier in 
the season. However, most communities are obtaining protection and 
there is very little serious injury. 
Utah. C. J. Sorenson (July 27): M. bivittatus and M. f emu, r - rub rum are 
moderately abundant in the- Uintah Basin and in northern Utah. 
Nevada. G. G. Schwcis (July 20): The grasshopper control campaign has
