Deg. , and several range species were dominant in the Northern States. 
Combinations of these named species plus M. differentials were the 
most important hoppers in the Southern States. In Colorado Pis so- 
steira longipennis Thos. was numerous and dominant in a large part 
of the range land in the southeastern quarter. (J. E. Parker and

EUROPEAN CORN BORER 
This insect is treated fully "by A. M. Vance of the Bureau of 
Entomology and Plant Quarantine, in a Supplement to No. 9 °f the 
Insect ?est Bulletin (November 15, 193&) • 
CORN EAR WORM 
The first report of the year of the occurrence of this insect 
was received in January from southeastern Texas. By the third week 
in March egg laying was observed in the coastal sections of north- 
eastern Texas, and by that time the insect was damaging corn in 
Louisiana and other Gulf States, as well as in southern California. 
By the middle of May larvae were observed in Georgia and very heavy 
infestations in tomatoes were observed in parts of Mississippi and 
southern California. During the first week in July egg laying was 
observed in northern Iowa and the insects were severely damaging 
corn as far north as Kansas, Tennessee, and Kentucky, in the Miss- 
issippi Valley, and in Washington, on the. Pacific coast. During 
the spring and summer the insect was generally scarce throughout 
the country, except for a few areas in Texas where considerable 
damage was done to cotton; however, in September populations de- 
veloped rapidly from New England to Iowa and southward to North 
Carolina and Tennessee. Serious crop damage was quite generally 
reported throughout this region to tomatoes and late sweet corn. 
The outbreak on the Pacific coast developed to such an extent that 
in December 65 percent of the sweet corn was infested in some places 
in California. 
CHINCH BUG 
Hibernating chinch bugs wore present in 1936 in moderate-to- 
extreme numbers in northern and central Illinois, southern Icwa.the 
northern half of Missouri, and eastern Kansas. About six counties 
in southwestern Iowa, and an area of similar size in southeastern 
Iowa, extending a few miles over into Illinois, containei extremely 
large numbers of bugs. Infestation was from light to moderate in a
