Mr. Riley — Dear Sir: Herewith please find a worm or grub 7 

 which has bothered my grape vines, it cuts the vine off about 3 or 4 

 inches under ground and takes out about an inch. Set vines last 

 spring. Put stakes of oak, green. 



Respectfullv, &c,

Proe. Riley, State Entomologist : I leave here for you a specimen 

 of a worm which h.is proved very destructive in my vineyard this season 

 having killed 24 vines, usually commencing at the bottom eye and 

 eating the entire stem almost to the surface of the ground. I have 

 dug up all the vines and in each case have found bat one worm some- 

 times as deep as 18 inches below the surface. My vineyard was planted 

 this spring on ground previously cultivated; has been thoroughly sub- 

 soiled and is well drained; the vines are Hartford Prolifics aud Con- 

 cords. Please send any information of value you may have relating 

 to the above to Col. John H. Hogan, Pevely Station, I. M. R. R. 



Verv respectfully, 



JOHN h. hogan.

Mr. Riley Dear Sir : The Grape-vine borer has been quite de- 

 structive in our vineyard this season, having killed 15 vines. Except 

 in two cases we found and dispatched him without mercy. We first 

 noticed the effects of the borer about the latter part of July and fre- 

 quently found them until the latter part of August. In some instances 

 we found the root severed within ^ half an inch of the surface, while 

 the borer was found at the bottom of the root. In others the root 

 was eaten off from 5 to 8 inches below the surface. Only Concord 

 vines have been affected, and only those that we obtained from a 

 neighboring vineyard for planting last spring. Not one of our original 

 vines have been destroyed, though we have 4 acres equally exposed 

 to the attacks of this new destroyer. Any information that you may 

 be able to give us upon this subject will be thankfully received. 

 Very respectfully,

Mr. D. C. Peebles, D. D. S., of St. Louis, also brought me a large 

 Concord vine that had been entirely severed from the roots and killed 

 by this worm, and I also received specimens about i grown from T. 

 W. Guy, of Glenwood. 



The above letters convey a very good idea of the manner in which 

 this borer works. It seems to have occurred in the Concord vines 

 more generally than in those of any other variety, but I think that 

 this may be attributed to the fact that more Concords are planted 

 than any other kind, for as the following facts will show the borer is 

 evidently a very general feeder. In the early part of June, 1867, Mr
