GEAPE INSECTS. 



We are glad to announce that our 

 State Entonaologist, Mr. C. Y. Eiley, 

 of this city, has consented to keep us 

 posted from time to time on the in- 

 sects which are injurious to the grape 

 vine, and we can also promise our sub- 

 scribers .that any question under this 

 head, if aeeonijianied with specimens, 

 will receive due attention. 



With his permission, we copy the 

 following account of the new root 

 !borer, from his most excellent report. 



THE NEW GRAPE-ROOT BORER. 



(OrthoKoma cylindricum, (?) Fabr ) 



The ad interim 

 committees of the 

 Illinois and Missouri 

 State Horticultural 

 Societies, while vis- 

 iting the orchards 

 and vineyards along 

 the line of the Iron 

 Mountain Eailroad, 

 discovered that s\m- 

 dry grape vines on 

 ])r. C. AV. Spauld- 

 mg's place were dy- 

 ing ; and on digging 

 lip such vines, the 

 loots were found to 

 bo entirely hollowed 

 out, and in many in- 

 ' stances severed, by 

 I a worm which is 

 fiiithfully repi-esent- 

 ((coieoptcra, rrionid;«,)ed at the head of this 

 .article — Fig. 67. At about the same 

 time, Mr. Walsh, of Rock Island, 

 received an immense specimen from 

 W. D. F. Lummis, of Makanda, 111., 

 with the same account of its habits; 



and the following letters, which I 

 have since received, relate to the same 

 worm : 



Mr. Eilky — Dear Sir : Herewith 

 please tind a worm or grub,']which has 

 bothered my grape vines. It cuts the 

 vine off about three or four inches 

 under ground and takes out about an 

 inch. Set vines last spring. Put 

 stakes of oak, green. 



Respectfully, kc, 



Alfred Barter.

Prof. Eiley, State Entomologist : 

 I leave here for jou a specimen of a 

 worm which has proved veiy destruc- 

 tive in my vineyard this season, hav- 

 ing killed twenty-four 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 but one worm, sometimes as 

 deep as eighteen inches below the 

 surface. My vineyard was planted 

 this spring on ground previously cul- 

 tivated; has been thoroughly sub- 

 soiled aud is well drained'; the vines 

 are Hartford Prolifics and Concords. 

 Please send any information of value 

 you may have relating to the above 

 to Col. John H. Hogan, Pevely Sta- 

 tion, I. M. E. r: 



Yciy respectfully, 



John H. HoGxiN.
