Hew Yovk P. J. Parrott (July 16). "Terminal growth of apple tree heavily infest- 
ed in Ontario County. CU. - raeryman near Gkuisva has just completed 
the fourth treatment of apple plantings." 
L. P. SLric'zlanu (A ;• jt 15). "Almost entirely absent in Niagara 
County." 
I*. Z. Kartzell (August 13). "Much less numerous than usual in Chau- 
tauqua County." 
G. R. Crosby and assistants report this insect as fairly common during 
the middle of July in Nassau County. \t that time it was not very 
abundant in Albany County, but by July 22 terminal grov/th of some 
young trees was noticed to be heavily infested. By August 15 no 
serious outbreak had developed., however. In Ulster County the insect 
was very abundant on occasional trees about the middle of July; they 
were disappearing rapidly by July 23, and had practically disappeared 
from the apple tree hy July 20; however, belated individuals were still 
to be found on young trees by August 17, and the infestation was no- 
ticed to have stunted the growth to a considerable extent. This 
insect was not abundant enough in Clinton County to attract much attan- 
tion. 
Illinois W. P. Flint (August 18) . "Reported as doing some damage in 2 and 5 
year old apple orchards in southern part of State." 
Idaho R. H. Smith (August 15) . "This insect was becoming apparent in younger
