the almost total destruction of the bloom in the acre of early Moore 
grapes noticed above. It is possible that this new American pest 
is an introduced species, brought to the Chautauqua region on re- 
cent importations of grape. It is to be hoped that it will not mul- 
tiply greatly and become a serious menace to this important 
industry. 
Remedial measures. Nothing very definite can be advised in 
the way of control measures. Clean culture, supplemented by lib- 
eral feeding, is the most hopeful method of avoiding serious in- 
jury, as we have yet to find this insect very abundant throughout 
large, well cultivated vineyards. Most of the infested clusters so 
far as our observation goes, occur near the outside of a vineyard 
in the vicinity of abundant natural shelters. The burning over of 
grassy headlands and margins of ditches in early spring could 
hardly cause much injury and might be of service in destroying the 
wandering maggots. The delicate parent insects would succumb 
readily to pyrethrum powder and presumably would be stupefied 
by heavy smoke. These insects fly mostly during the quieter part 
cf the day and it might be practical, in the case of a badly infested 
vineyard, to watch for the appearance of the adults and then 
stupefy or destroy them by generating a heavy smudge throughout 
the vineyard. Attempts to control this midge by applications to 
the vines before the flies appear are very likely to result in failure.

Gladioli aphid 
Aphis gladioli n. sp. 
The abundant occurrence of a plant louse upon gladioli bulbs is 
something unusual. No outbreak of the kind had been previously 
brought to our attention, and Dr L. O. Howard informs the writer 
that he is unable to find any record of an aphid occurring upon 
this showy plant. This new form of injury was first brought to
