OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR "g|jfc, 1931. 
Probably the most serious insect "development of the month is the 
severe armyworm outbreak occurring over 11 counties in north central 
Texas. A similar outbreak is under way in Mississippi and Kentucky 
with lesser outbreaks in eastern Arkansas and the eastern shore of 
Virginia. ...'•".: 
Cutworms seem to be unusually prevalent along the Atlantic Sea- 
board. These insects are also very troublesome this spring in the 
East Central States, and westward to Montana, the Dakotas, and 
Nebraska. The remainder of the country is experiencing about the 
normal cutworm damage. 
Daring the first week in May grasshopper", eggs were found to be 
very numerous in South Dakota and at that time began hatching in 
Montana and Nebraska. By the third week in the month, hatching was 
reported from the Great Basin. The Salt River Valley of Arizona and 
the Antelope Valley and the Klamath Lake district of California are 
having localized grasshopper outbreaks. . 
Owing to the cool weather of late spring considerable wireworm 
injury was reported from scattered localities throughout the United 
States. 
As a whole, the Hessian fly situation does not seem to be alarming, 
although Illinois reports that from 32 to 40 per cent of the tillers are 
infested in certain fields. 
The chinch bug situation in Illinois, Missouri, and parts of 
Kansas appears to be rather serious. Large numbers of the bugs are 
in the fields', and in some cases in Illinois are killing wheat, while 
in Kansas 'reports of the killing of a lot of oats by this insect have 
been received. 
The corn ear worm is commencing to appear in destructive numbers 
in the Gulf States.
