OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR SEPTEMBER, 1930 
Grasshoppers still continue to attract considerable attention through- 
out the greater part of the country. In many places the damage has even 
increased over that done in August. 
Several species of cutworms are reported from the Rocky Mountain and 
the -Vest Coast States. 
The fall armyworm became generally prevalent over the Middle Atlantic 
States during the month, attracting unusual attention by attacking lawns 
in 1 077ns and cities. 
Damage by white grubs is becoming very evident, as the season advances, 
in the Central States from Indiana westward to Nebraska, and southward to 
Missouri . 
In this number of the Survey Bulletin is a summary of the survey work 
on the Hessian fly for the Middle Atlantic, East Central, and .Vest Central 
States. The Hessian fly situation as a "hole is not. alarming. From con- 
ditions in southern and west-central Illinois and parts of Missouri and 
Indiana, however, there is reason to believe that unless checked by adverse 
weather conditions this insect will be decidedly more troublesome next 
year in this region than it has been in several years. 
The cotton leaf worm made one of its very extensive northward flights 
about the middle of September. The moths were observed in large numbers 
in southern Missouri on September 14,, in southern Illinois on September 15, 
in the District of Columbia on September 23, in southern Michigan and New 
York City on September 24, and in Boston, Mass., on September 25. 
Codling moth eggs continued hatching during the first two weeks in 
September in Illinois, Indiana, and Kentucky, and moths were still emerging 
in centr-1 Ohio during the third week of the month.
