FALL ARWYWOBM . 
Daring late June the fall armyworm ( Lapbygma frugiperda S. & A. ) 
started 'at t c acks in outbreak numbers in the Gulf region and the South 
Atlantic States. The infestation in Florida was the most severe since 
1912. Later in the summer this insect also did much damage in the 
Lower Rio Grande Valley of Texas and outbreaks were reported from other 
sections., and by fall it T ras quite generally prevalent over the Middle 
Atlantic and East Central States. Apparently the long, dry summer pre- 
vented the growth of succulent grass in pasture lands and caused the moths 
to lay their eggs on snail patches of any green food available. As a 
result, hundreds of lawns were seriously over- run by an unusual number of 
caterpillars. Fall-sown wheat and other small grains which were planted 
for early fall pasture also became rather heavily infested.

The velvetbean caterpillar ( Ant i car si a gemmatilis Hbn.) was very 
decidedly less troublesome this year in the Gulf region where the r.o'st 
serious outbreak on record was recorded last year. It appeared this year, 
however, in destructive numbers in some districts of Louisiana and Okla- 
homa.

Luring the latter part of April the corn ear worm ( Heliothis obsolete. 
Fab.) was appearing in moderate numbers over the southern part of Florida* 
During May it was reported quite generally prevalent in the southern "art 
of the Gulf States and in southern and central Texas. 3y the middle of 
July it was acr earing in destructive numbers in the Carolinas and cor::
