Acer pseudoplatanus L. (= Plane tree). From the upper surface of the 
leaf project numerous ‘nailgalls,’ cylindrical, or rather swollen 
upwards, = = 1 inch, externally smooth and bright red; they open 
on the lower surface in a small pit by a narrow hole blocked up_ 
with projecting transparent simple unicellular hairs; the interior 
above is smooth. Galls examined 7/6/75 showed no occupants ; 
others examined 10/7/75 showed multitudes of a mite, Phytoptus 
(Ceratoneon vulgare Bremi = Volwulifer Aceris Amerling), The galls 
are common on some trees at Banchory-Ternan.

Ulex Europeus L. (= Whin, Furze, or Gorse). The galls are altered 
flowerbuds and resemble externally a flowerbud much enlarged 
and inflated; they are oval, about 2 x } inch, externally green, 
and covered with pubescence which is whitish towards the base 
but brown towards the tip of the gall. In the interior is a large 
cavity in which there is not a trace of the inner whorls of the 
flower, but the walls are lined with a short white pubescence. 
Each is tenanted by one larva of Cecidomyia (Asphondylia) Ulicis 
Trail. (HE. M. M, XI. 225, described by Mr. Verrall.) The galls 
are common on Scotston moor, on the Links, at Nigg, &c. They 
have been recorded by Mr. Binnie from near Glasgow, and by 
Mr. Verrall from near London. 
Cytisus Scoparius Link (= Broom). A.; the gall is a distorted pod 
which remains green and seldom grows large; part of it towards 
the base becomes inflated forming an oval swelling about ; x 4 
inch, with rather thin walls, and no trace of the seeds. Each gall 
contains from 2 to 10 larve of Cecidomyia (Asphondylia) Swrothamnt 
Lew. They are abundant around Aberdeen, at Banchory-Ternan, 
in Glengairn, at Alford, at Inverurie, on Scotston moor, &e. 
B. ; The gall is a flowerbud which remains green, though more than 
half the size (+ x 3 inch) of a mature flower bud, it is smooth ex- 
ternally and oval in form. It arises from the axil of a bract™ 
among the flowers on a flower-bearing branch, (often 2—3 on a 
single branch), and frequently shows sepals surrounding its base, 
but no other part of the flowers can be distinguished. The 
central cavity is pretty large, and is tenanted by one (or more ?) 
larva of C. Sarothamm; common at Banchory-Ternan, and on 
Scotston moor. 
C.; tubular galls arise in the axils of the leaves towards the tips of the 
apical branches; they are budlike, === x 74 inch, flattened 
cylindrical, externally green, and smooth or somewhat ribbed ; 
they are bilabiate and open above, and on longitudinal section 
present a smooth-walled cell below, while the walls are lined with 
white hairs above, decreasing towards the entrance. Each cell is 
tenanted by 1 orange larva of a species of Cecidomyia. The galls 
are common at Muchalls, at Rubislaw, at Banchory-Ternan, at 
Inverury and on Scotston moor. 
Trifolium repens L (= White Clover). One (or more) of the leaflets 
remains folded (conduplicate) and becomes hard, rather fleshy, and 
inflated towards the midrib; the inflated part is yellowish-green, 
but the gall is not at all conspicuous; each is tenanted by one 
white or reddish larva of Cecidomyia Trifolu, Fr. Law.. The galls 
are abundant near Old Aberdeen. 
Anthyllis Vulneraria L (= Wound-wort, or Kidney vetch). The gall is
