percent. The direction of the flight was towarc the southwest and coin- 
cided with that of a slight breeze. Luring the hour after the migration 
was first noticed, nearly IOC butterflies were seen flying at a height 
of H-10 feet across a 2-acre field* Jl being counted during the first 10 
minutes. The flight was stopped by darkening of the sky due to a local 
shower, A few butterflies sought shelter in clumps of bamboo. 
Haiti. A. Audant (June 20): We have noticed the first flight in Port-au- 
Prince, going toward the east. 
CEREAL AO FOE AGE-CROP I IT SECTS 
WHEAT 
HESSIAN FLY ( Phyt ophaga destructor Say) 
Indiana. H. R. Painter and W. 3. IToble (September 23): Hessian fly infes- 
tation has increased considerably this season, favored by the rather abunian; 
growth of volunteer wheat. All stages of larvae as well as puparia are 
present in volunteer. Parasitization is likewise on the increase. In 
the vicinity of La Fayette the degree of parasitization of the summer 
puprria is about 75 percent. Unless unfavorable conditions next spring 
chech development serious damage may be expected. 
Ohio. T, H. Parks (September 2G): Volunteer wheat carries a plentiful 
supply of eggs. Very little wheat has been sowed anywhere in the State. 
There is plenty of volunteer wheat, however, to carry over a heavy fall 
brood. 
Nebraska. M. H, Swenk (September 15): The hessian fly abundance is at a 
very low ebb. 
WHEAT STEM MAGGOT ( Meromyza americana Fitch) 
South Dakota. H. C. Severin (September 20): Wheat stem maggot damage 
ranged from 5 to 27 percent, chiefly to wheat and barley. 
CORN 
CHINCH BUG (Blissus leucopterus Say) 
Indiana. C. 3enton and A, C. Cole, Jr. (September 23): A few second-brood 
adults in cornfields in Tippecanoe County have reached maturity. Num- 
bers of bugs in bunch grasses have gradually increased since August 2?, 
the date they were first found. This date apparently marks the initial 
entrance of bugs into hibernation quarters. Their appearance first in 
clumps of Elymus spp. indicates an apparent preference for the drier 
grasses. Adult females fail to show the presence of eggs but are stor- 
ing up fat. Bugs in a few cornfields are rather heavily infested with 
a fungus.
