Questions Lintner’s conclusion that the injurious manifestation 
of the chinch bug in New York is due to an invasion, As the 
species has been found much farther north it seems more rational 
to suppose that it has only unduly increased where, though present, 
it had not heretofore been detected. The apparent lack of sus¬ 
ceptibility to wet weather he attributes to the excessive multipli¬ 
cation of the insect during the very dry seasons of 1880 and 1881, 
and its ability, demonstrated in the West, to brave unfavorable 
weather for a time. This will tell, however, on the hibernating 
Illinois Cnors for 1883. Circular No. 106 [of the Department
