C. R. Crosby and assistants report this insect as being quite numerous 
in Erie County the middle of August. In Wayne County some fields were 
damaged to the extent of 40 to 50 per cent by the middle of July, and 
by the end of July practically- ail of the loaves wore tip-burned in 
Wayne County. Rather plentiful and destructive in Orleans, Steuben, 
Genesee, Onondaga, Cayuga, Ulster, and Washington Counties. Present 
in small numbers in Nassau County. Dusting with 2 per cent nicotine 
dust and Bordeaux has .proved of little value in repelling this pest." 
Wisconsin S. B. Fracker (July 26). "About asnumerous as during the season of 
1919 and 1920 throughout the State." (August 25). "The leafhopper 
became a serious limiting factor in the commercial growing of potatoes 
in the northern counties for the first time this year." 
.Minnesota A. G. Ruggles (August 19). "Perhaps oneof the most abundant and de- 
structive insects of this summer has been the apple leafhopper on po- 
tatoes. It has done a tremendous amount cf damage throughout the pota-

bers in Nassau and Steuben Counties and about in normal numbers in 
Albany County." 
THREE-LINED POTATO BEETLE ( Lena trilineata Oliv.)

numbers this year in Wayne, Steuben, and Chautauqua Counties. 
NORTHERN TOBACCO R0RNW0RL1 (Phle gethontius quinquemaculata Haw.) 
C . R. Crosby and assistants (August 15). "Present in small numbers in 
Erie County; were quite numerous during the latter part of July. Lar- 
vae fGund in destructive numbers in several fields in Genesee County, 
first two weeks in August, in many cases stripping the foliage of at 
least 10 per cent of the plants, also unusually common on tomatoes. 
More numerous than usual inOrleans County. Causing considerable injury 
in one 6-acre field in Onondaga County. Present in about normal num- 
bers in Chautauqua and Ulster Counties . This pest is also doing con- 
siderable damage in Nassau County on Long Island." 
S. B. Fracker (July 26) . "A very sudden and unusually serious outbreak 
of this insect occurred during the last week of July in Fond du Lac 
and Lincoln Counties. This outbreak attracted much newspaper attention. 
Many growers are now sp raying and dust in ."
