Salix nigra (black willow) 



133 A bud deformation of the flower catkins (fide Walsh '64, 

 p.6o8) and leaf buds or parts of leaves (fide Cook) producing a 

 large irregular crumpled mass, or core covered with filaments.

 Evidently a variable form, but Walsh's and Cook's descriptions 

 are much at variance. Of course the name transferred from the 

 gall to the undescribed mite has no standing. 



134 A pocket or capsule-gall, irregularly hemispherical, green- 

 ish yellow, with a projecting aperture; on either surface of the 

 leaf but chiefly above.

 This seems fully identical with no. 127, etc. The mite is un- 

 described. Cook appears to have recognized this and the preceding 

 on other species of willow, not specified. 



*I35 Small and very crowded pocket-galls upon the leaves.

136 '' A small, rather irregular more or less spherical gall occur- 

 ring in great abundance on the upper surface of the leaves."

The identification is of course erroneous, see our nos. 127 and 

 131. Although Cook separated this frpm Pur no. 134, no distin- 

 guishing marks are given,
