 the grape-vine Fidia, thns establisliing the identity of the grubs, 

 and in October, 1895, Mr. Are])ster pnblisiied an adniiral)le l)nlletin 

 (Bull Xo. 02, Ohio Kx|). Sta. ) on the insect. Having had but little 

 opportunity to study the pest in Xew York, and as ^Ii". Webster's 

 work has been so thoruUi>-hlv well done, uur statements in this

The pest has done much damage during the past six years in 

 vinevards alonjj' Lake Erie east of Cleveland, Ohio, and in IS99 a 

 serious outbreak was reported at Bloomington. 111. It seems to 

 have spread slowly in Ohio, and probably the outbreak in New 

 York near Ripley, in Chautauqua County, has resulted from the 

 eastward spread of the insect. It is evidently spreading slowly near 

 Ilipley where 10 or 12 acres of one vineyai-d have been already 

 ])ractically ruined. 



It is to be hoiked that its ravao-es mav be 

 limited in our State, for it is the most serious 

 and dangerous insect enemv which has yet made 

 its appearance in our vineyards; it feeds both 

 on the roots and leaves, and it is proving to be 

 a difficult pest to control. It is capable of killing 

 the vines outi'ight, and when present in injurious 

 numbers it usually seriously weakens or stunt> 

 the vines.
