and southern part of the State, from Bloomington and 
gn to Alton and Centralia. It was first noticed this year, 
, on strawberry plants at Normal, only the wingless form 
y at that time. It was collected at Centralia, August 6, and 
as late as September 25, at which time it still occurred 
;m the under sides of the leaves. It has not thus far done 
reciable injury as far as known.

pecies, treated as a strawberry insect at considerable length 
ist year’s report, has been carefully observed this season, to 
ie some unsettled points respecting its life history and its 
to the strawberry. Our notes began April 1, when Mr. 
was sent to Southern Illinois to collect the facts relating 
fe history of this species in spring. At this time he found 
t abundant among the young and tender leaves of mullein, 
strawberry fields and elsewhere,—not down among the older, 
ives, where they would naturally have resorted if in search

lies were distended. Very few specimens were found except
