CAKILE MARITIMA L.:— 
Near junction of root and stem there are lateral swellings about 
the size of half a pea, and very similar in appearance and in 
structure to the galls of Ceuthorhynchus, formerly noticed as so 
common on Turnip and Cabbages; and like them, the work of a 
weevil belonging to that genus. The galls are to be found on the 
sandy beach near Donmouth, north from Aberdeen, in July. (ZV, 
p. 13): : 
EROPHILA VERNA L.:— 
' The galls on this plant, previously recorded by me (1. c., VZ, 
p. 13), were sent me by Dr. White from Perthshire. In May 
1884, I found these galls on plants on the links north of the 
Don, near Aberdeen. They are small oval or roundish swellings 
at the junction of the root and of the stem, usually concealed in 
the rosette of leaves ; they seldom exceed 3 or 4 mm. in diameter. 
Their wall is thin, with a relatively large space tenanted by a 
larva, apparantly that of Ceuthorhynchus Drabae Lab. Owing 
to its position and ‘minute size, the gall is probably far more 
common than it would at first sight seem to be. 
HELIANTHEMUM VULGARE Gaertn.:— 
Besides the Midge-gall described in my former paper in our 
“Transactions,” another gall has been found by me, consisting of a 
shortened and mal-formed condition of the leaves and buds on one 
or more of the twigs, or even on the greater part of the plant. 
The epiderm of all the affected parts is covered with short gray 
hairs, which coating renders the galls moderately conspicuous 
despite their small size individually. They are the work of mites 
of the genus Phyfoptus, and are quite distinct in appearance from 
the galls of Cecidomyia (Diplosis) Helianthemi Hardy, just referred 
to. They are not uncommon on a small area near the highest 
part of Scotston Moor, near Aberdeen ; but I have not met with 
them elsewhere, nor have I met with them before autumn. (VZ., 
p. 4). 
TILIA EUROPA L.:— 
Rolled, thickened, red, fleshy margins of the young leaves, 
usually on the young shoots; each is occupied by one or more 
reddish-orange larvae of gall-midges (Cectdomyia). On one or two 
trees in Old Aberdeen, in July. (V., 274). 
On this tree Dr. White has found, in Perthshire, swellings 
varying in dimensions from the size of hemp-seed to that of a small 
pea; these swellings occur on the flower-stalk at the bract, or where
