THE STATE ENTOMOLOGIST. 63 



Miss()ui-i will doubtless succeed in France. Such of our vines as have 

 already been cultivated there are often differently classified by their writers 

 to Avhat they are by American authors, and confusion consequently ensues. 

 Thus, one of my correspondents, M, Laliman, of Bordeaux, who has cul- 

 tivated a number of them for several years, classes the Clinton and Taylor 

 as cestivalis, and the Norton's Virginia and Delaware as Jjabrusca* 



I will now indicate the susceptibility of different varieties to the disease. 



Vitis vinifera (European). — All European varieties Avith roots badly 

 affected. In many instances decomjjosed and gone, with the vines about 

 dead. No leaf-galls. 



T'. riparia (River Bank). Clinton. — Leaf-galls extremely abundant. 

 Eoot-lice only moderately so. Ta3dor — Where leaf-galls are few, root-lice 

 abundant; where galls are abundant, fewer root-lice. Delaware — A few^ 

 leaf-galls; lice abundant on roots. Othello (hybrid with vinifera) — Both 

 leaf-galls and root-lice, the latter tolerably numerous. Louisiana (some 

 say a seedling of vinifera, others again believe it cestivalis) — Leaf-galls and 

 root-lice, but neither bad. Alvey — Few leaf-galls; plenty of root-lice. 

 Cornucoj^ia (hybrid w^ith vinifera) — No leaf-galls ; roots badly affected with 

 lice. Wild vine — Numerous leaf-galls and a few root-lice; much in same 

 condition as Clinton. 



T'. cestivalis (Summer). Cunningham — No leaf-galls, but a few root- 

 lice. Cynthiana — Occasionally a few galls; lice abundant on roots. The 

 vine has a vigorous growth and the roots are large and strong. Herbemont 

 — A few leaf-galls, and scarcelj- any root-lice. Norton's Virginia — No leaf- 

 galls, but some root-lice. 



V. Labrusca (Northern Fox). Isabella, or seedlings of Isabella — No leaf- 

 galls ; a few root-lice : roots strong and vines flourishing. Martha — No 

 leaf-galls; very few root-lice. Hartford — No leaf-galls; very few root-lice. 

 Concord — No leaf-galls; scarcely any root-lice. Almost entirely exempt. 

 Ives — No leaf-galls; lice tolerably abundant on roots. North Carolina — No 

 leaf-galls; very few root-lice. Maxatawne}' — No leaf-galls; root-lice quite 

 abundant. Creveling — A few leaf-galls; root-lice abundant. Catawba — 

 No leaf-galls; root-lice very numerovis, abounding even on the larger 

 roots as on the European vines. Goethe (hybrid' with vinifera) — No leaf- 

 galls, but lice on roots \qyj numerous. In the vineyards of Messrs. Isidor 

 Bush k Sons, of Bushburg, Mo., this vine was very vigorous and thrifty in 

 1869 and 1870, but has done poorly the present year. Dracut Amber — No 

 leaf-galls ; few root-lice. Wilder (hybrid with vinifera) — No leaf-galls ; not 

 «uany root-lice. Challenge (Iwbrid with vinifera — No leaf-galls ; roots af- 

 fected but moderately. Diana — No leaf-galls, but plentj^ of root-lice. 



Y. vulpina (Southern Fox or Muscadine) — As it is not grown in this local- 

 ity, being considered absolutely worthless here, I know little about it. 



From this experience it would appear that no vines of those named, are 

 entirely free from the attacks of the root-louse; but that the European va- 

 rieties are most suscejjtible to it — the Northern Fox, next in order, the
