Triadenum virginicum (marsh St John's-wort) 

 (E lodes virginica) 

 145 An erineum (?) of very fine and numerous black spots on 

 the upper side of the leaves. 



Hagen '85, no. 43 • 111. 



Very probably a fungus. 



Ulmus americana (American white elm) 



^146 Small green to yellowish pocket-galls, more or less spherical, 

 usually on the upper side of the leaves. The mite is Eriophyes 

 u 1 m i (Garman).

 Jarvis '07, p.59, pi. B, fig. 5-6 Ont. 



Specimens from Catskill, and occurs at Geneva (Parrott in 

 litt.). The mite is reported from Newport (Felt '02). N.Y. 



Ulmus fulva (pubescens) (slippery elm) 



147 A large pouch-gall (up to 2 cm) on the leaves. Differs 

 from the preceding in its unusual size and in often commencing as 

 a cone or deep dimple. 



Jarvis '07, p. 63, sixth sp. Ont. 



This may be one of the three undescribed galls on elm enumer- 

 ated by Walsh [Ent. Soc. Phila.Proc. ¥1:285]. 



*T47^ Irregularly lobed pubescent pouch-galls, resembling 

 those on Tilia (no. 144), and much smaller than the preceding 

 (3 to 6 mm), have occurred abundantly at Catskill this summer 

 (1908), seriously affecting the leaves, although none were ob- 

 served in the previous year. The mites are very numerous, 

 cylindric and whitish. N.Y. 



148 A small greenish pocket-gall on the upper side of the leaves, 

 quite similar to our no. 146, and probably made by the same mite. 



Specimens from Pownal (Mr Burnham). _ Vt. 



Ulmus racemosa (rock elm) 



149 The same as our no. 146.
