whitish, while the leaf is green, but till maturity they are 

 green like the leaf. They are then very difficult to find, 

 the readiest eye-mark being the radii which pass from a 

 small knob in the centre to the circumference. On the 

 upper surface this arrangement is very regular and distinct, 

 . but it is less regular below, and there is no central knob. 

 Both surfaces are naked. The form is oval, about \ x ^. 

 Almost all that I found were empty, but a few contained 

 inquilines. 



Brassica campestris L. (Turnip). — Last February, at Old 

 Aberdeen, I found galls of Ceuthorhynchus sulcicollis Gyll. 

 on roots of turnips. They are scattered irregularly over the 

 root, especially below the surface of the earth; and project 

 rather more than half a hemisphere of \ to \ inch diameter. 

 Walls in consistence and appearance are like the root. The 

 galls are monothalamous and are usually distinct, but some- 

 times two or more are united. 



Hypericum pulchrum L. — The galls on this plant already 

 described have been found by Dr. White at Castleton of 

 Braemar this summer. 



Ulex europ^us L. — On this plant, Mr. Verrall, during a visit 

 to Aberdeen this summer, detected galls on Scotston Moor, 

 near Aberdeen. I afterwards found the galls abundant near 

 Aberdeen, and succeeded in rearing from them an Asphon- 

 dylia which resembles pretty closely Asphondylia sarotham- 

 ni ,but is larger than this species. As it differs in its food- 

 plant from any described species, and is larger than A. 

 sarothatmii, its nearest ally, I now propose for it the name 

 of Asphondylia ulicis. The galls so closely resemble large 

 flowerbuds as to be readily overlooked, though easy of de- 

 tection after once being recognised. They are a good deal 

 larger, and more inflated than the flowerbuds, but otherwise 

 agree with them closely in appearance. Size about ^ inch 

 by % inch. Monothalamous, enclosing a large cavity in 

 whirh there is not a trace of the inner whorls of the flower. 

 Walls lined with a short white pubescence on which the 

 larva feeds. 



Cytisus scoparius L. — (c) During the summer I have found 

 a gall which differs from both kinds (pcd galls and leaf bud 

 galls) already described in consisting of a distorted flower-
