GRAPE LEAFHOPPER ( Ervthroneura comes Say) 
v York E. P. Felt (July 21) . "The grape leafhopper appeared to be somewhat 
abundant in portions of the Chautauqua grape belt and in parts of the 
Hudson Valley. On June 30 considerable numbers of wingless hoppers 
were observed in northern Columbia County." 
C. R. Crosby and assistants (June 24). "Infestation in Ulster County 
does not seem to be very heavy this year. The first eggs were ob- 
served in Chautauqua County hatching on June 17." 
L. F. Strickland (June 10) . "Adult leafhoppers are unusually numerous 
in Niagara County vineyards . Infestation is as heavy as that which 
produced the outbreak in 1916." 
ACHEMON SPHINX ( Pholus acheroon Drury) 
Lifornia A. J. Flebut (July 18). "This insect is far more abundant than usual 
in Madera County. First brood was partially controlled by spraying 
and the second brood is just hatching." 
WHITE-LINED SPHINX ( Celerio line at a Fab.) 
Lifornia A. J. Flebut. "Several instances were noted where full grown cater- 
pillars had left drying up grass field and attacked vineyards. 
Practically all outbreaks were in new vineyard sections in the San 
Joaquin Valley. Hand picking seems to be the only satisfactory 
control." 
ALFALFA CATERPILLAR ( Eurvmus eurvtheme Boisd.) 
Lifornia A. J. Flebut. "These insects are leaving cut alfalfa fields and 
causing some damage in near-by vineyards in the San Joaquin Valley." 
YELL6^¥STRI1?£Bt^5HS^0BlC!( TVSHen£a o drnithogalli v ar. praefica Grote) 
Lifornia A. J. Flebut. "This is a pest throughout the San Joaquin Valley, 
leaving alfalfa, upx>n which it is generally feeding 7/hen cut, and 
entering near-by vineyards. Ditches are generally successful in 
checking inroads. Damage is slight except in case of young vines." 
GRAPEBERRY WORM ( Polvchrosis viteana Clem.) 
to H. A. Gossard (July 2l) . "I judge from material sent in that the 
grapeberry worm is more numerous in the grape districts near Cleveland 
than it has been for several seasons." 
FALSE CHINCH BUG ( Nysius angustatus Uhler) 
Lifornia A. J. Flebut. "This insect has been reported from several new 
sections in Tulare County. No control has been found that was 
successful ."
