BUFFALO TREEHOPPER ( Ceresa bubal us Fab. ) 
A. S. Mills (April 11): Punctures on apple limbs in Greene 
County were found rather commonly in a few orchards. 
G. A. Runner (May 10): Numerous reports have been received of 
injury to young apple trees. The buffalo treehopper is abundant 
in' the commercial fruit growing districts along the South Shore 
of Lake Erie and seriously interferes with the growth of young 
fruit trees in sod or along borders. Severe damage has been 
noted in orchards in alfalfa sod and trouble from this insect 
has prevented the practice of growing alfalfa in young apple 
orchards from becoming more general. 
PUTNAM'S SCALE ( Aspidiotus ancylus Putn. ) ■ 
C. R. Crosby (March 18): Infested bark received from Bennington. 
SAN JOSE SCALE ( Aspidiotus perniciosus Corns t. ) 
C. R. Crosby and assistants: By the middle of April reports were 
received of light infestations in Onondaga, Ontario, and Erie 
Counties. 
G. A. Runner (May 15): No increase in infestation over previous 
years can be noted. Examinations of peach orchards in Ottawa and 
Erie Counties show an extremely light infestation and there seems 
to be no evidence that the usual lime- sulphur sprays are not thor- 
oughly effective. Some of the orchards under observation are in 
a locality where one of the earliest outbreaks of the San Jose 
scale in the Eastern United States occurred. Counts of scales 
from twigs of unsprayed apple made during the period April 20-May 
10 indicate a high winter mortality. Six collections showed a 
survival of 47.2 per cent. 
B. A. Porter (May 21): First crawlers appeared May 20, which 
is 7 to 10 days ahead of normal and 20 days ahead- of last year. 
This early start on the breeding season will probably enable the 
scale to overcome to a large extent the extreme winter mortality 
wtiich has occurred. 
E. J. Newcomer (May l): Counts of scale in the Yakima Valley 
show a mortality of 35 to 65 per cent, due to the prolonged cold 
weather of December 16-27, 1924, during which time the temperature 
was below zero seven nights and reached a minimum of 10 below. 
In the spring of 1924 only 5 to 15 per cent of the scale was dead. 
OYSTER- SHELL SCALE ( Lepidosaphes ulmi L. ) 
P. J. Chapman (February 10): Infested twigs received from Oyster 
Bay. 
D. L. Hayes (April 11): 
in Wyoming County. 
Prevalent in a few orchards at Genesee
