Ohio, Indiana, Michigan. A. M. Vance (June 3): Pupation and emergence 
in these States is more advanced in the spring of 1938 than m any 
previous year on record. The first pupa in 1938 was found west 
of Toledo, Ohio, on May U, and the first evidence of moth emergence 
was noted in the same vicinity on May 26. The earliest previous 
records of pupation and emergence in this region were on May 2o 
and June 12, respectively, "both obtained in 1936. On May 11, 1938, 
pupation of 1 percent had occurred in a cornfield examined in 
Allen County, Ind., and on June 1, 2 percent of the larvae had 
pupated at Mouafc Clemens, in southeastern Michigan. Near Toledo, 
in fields probably infested to a large extent "by a second genera- 
tion of the corn "borer in 1937, pupation in 1938 averaged 6 per- 
cent on May 12, 6U percent on May 26, and 8^ percent on May 31, and 
in all cornfields examined, the seasonal development of the insect 
was unusually advanced. The observed mortality in the region in 
the spring of 1938 averaged only 2 percent.
