REPORT OF THE STATE ENTOMOLOGIST 1907 I5I 



Vitis cordifolia (frost grape) 

 157 Small semicircular or nearly circular 'Svart-galls " (cap- 

 sules?) along the veins, about 2 mm in diameter and but slightly 

 elevated on either surface of the leaf. Above paler than the leaf, 

 below with a white nipple surrounded by a furrow. 



Jarvis '08, p.94, second sp. Ont. 



158? A gall of " Eriophyes sp." on this species is figured by 

 Jarvis on plate D, figure 4, but not mentioned in the text. It is 

 evidently quite distinct from the above, being from 5 to 10 mm in 

 diameter and with long white pubescence on the lower surface. 



159 A green pouch-gall with irregular lobed top (as in that of 

 E. abnormis), mostly upon the under side of the leaf. " Not 

 common." 



Jarvis '07, p.62 (''Eriophyes vitis") Ont. 



The reference of this to E . vitis seems to be an error, [see 



the following] and the description is not greatly unlike the galls 



of the well known Phylloxera vastatrix (an Aphid), 



though more slender than the latter usually are. 



Vitis vinifera (grapevine) 



160 An erineum on the under side of the leaf, causing a swell- 

 ing above. Trichomes simple. The mite is Eriophyes vitis 

 (Landois). 



Banks '04. Treatise on Acarina, p. 106 Cal. 



Parrott '07. N.Y. Agric. Exp. Sta. Bui. 283, no. 9 (P h y 1 - 



1 e r ium V i t i s) 



This is probably the Erineum (Phyllerium) vitis of 



Schweinitz '34, no. 2799 (Persoon '22: no. 6). N.C., Pa. 



Persoon's description indicates that the erineum is pinkish and 



later brown. 



161 A leaf curl, or warty, greenish elevations on the upper 

 surface of the leaf, entirely smooth on the inner (under) side; 

 becoming browned or reddened when old. 



Forbes 1885. 14th 111. Repit, p.84 111. 



Referred doubtfully by Forbes to Eriophyes vitis, but 

 the total absence of trichomes seems to distinguish it notably, 

 moreover the mites differ somewhat. 



Vitis sp. (?) (wild grape) 



162 Forbes reports the preceding also on " wild grapes " in south- 

 ern Illinois, (Garman).
