belt of varying width surrounding the nore heavily infested area just 
outlined and extending fron south-central Oklahoma, east-central Kansas, 
and southeastern Nebraska to eastern Ohio, and frcn north-central Iowa 
tc southern Missouri. Early spring reports indicate only about 50 percent 
winter survival in Ohio, northern Indiana, northern Illinois, and southern 
Iowa, but a nuch higher survival in Missouri and Kansas. In northern Ok- 
lahoma winter survival was reported to be only about 21 percent. Spring 
migration to and establishment in small grains was rather slow in the 
more northern areas but spring and early summer conditions were, in gen- 
eral, favorable to development of the first brood. Injurious migrations 
to corn occurred on occasional farms in scattered localities throughout 
the 8crn Belt, fron southwestern Michigan to extreme southeastern Neb- 
raska and south into east-central Oklahoma and northern Arkansas. In- 
jury tc corn was also reported from the eastern Carolinas ond Virginia, 
southeastern Minnesota, Mississippi, and southern Texas. Summer con- 
ditions were also favorable tc the development of the second brood in 
corn in the more eastern part of the affected area, but in Kansas and 
Oklahoma the prolonged drought reduced infestations materially, along 
with the drying up of host plants. As a result of the early fall rains 
and more abundant food, however, the bugs made something of a late-season 
comeback in the Southwest. Fall conditions were fairly favorable to their 
activities and preliminary reports indicate that they are generally from 
moderately to extremely abundant in winter quarters from Western Indiana 
to southeastern Nebraska and eastern Kansas, and from southern leva to 
central Missouri and the Oklahoma-Kansas line. Scant to moderate num- 
bers are reported from Ohio, eastern Indiana, northern and southern 
Illinois, south- central Iowa, southern Missouri, northern Arkansas, and 
northeastern Oklahoma. At the close of the year the situation apparent- 
ly approaches that prevailing at the end of 1933. with a prospect of 
another outbreak in 1937* The accompanying map shows the abundance of 
chinch bugs in hibernation in the fall of 193°« In the central area 
local injury is likely, and, if spring weather favors the bug, general 
injury is anticipated. In the surrounding area local injury is likely 
if the weather favors the bugs. This sunmary is based principally on 
information supplied by the State entomologists of the States concerned 
and on supplementary data from the stations of the Bureau of Entomology 
and Plant Quarantine in the States. (C. M. Packard, Bureau of Entomology
