not conspicuous consisting only of a flowerbud which becomes 
somewhat inflated, and remains unopened while the other buds in 
the head are in flower, but externally differs little from an ordin- 
ary flowerbud. It also becomes fleshy and hard, (the calyx alone 
excepted); each contains several orange larvae from which I have 
reared Cecidomyia (Diplosis) Loti, DeGeer. The galls are common 
on the sandhills along the coast. 
Lotus corniculatus L. (= Crowsfoot, or Bird’s-foot-trefoil). A. The 
galls like those on the last mentioned plant are deformed flower- 
buds which either do not flower at all, or produce a very much 
distorted flower. They become much inflated (3 x %-4 inch) 
ovate, fleshy, smooth externally, and deep red on the side most 
exposed to light, elsewhere yellowish. Internally all the organs 
are present, but they are much thickened, and between them live 
several larvee of Cecidomyia (Diplosis) Loti, De Geer. (Sometimes a 
larva of one of the Tortrices ? is also to be found inside as an in- 
quiline). The galls are abundant on the sandhills along the coast; 
I have also found them at Muchalls, and in Glengairn. 
B.; The galls are terminal, and consist of an ovate cluster of imbricate 
leatlets which are slightly thickened and fleshy, but do not other- 
wise differ from young healthy leaves. The gall is about} x 3 
inch. It contains one or more reddish orange larve of Cecidomyia 
(Loti De Geer ?). Occurs along with the last. 
Lotus major Scop (Narrow-leaved Bird’s-foot-trefoil).—On this plant 
I have found galls like A. on L. corniculatus, L. consisting of 
swollen flowerbuds which become hard and fleshy, deep red on 
the side exposed to the light, and usually do not attempt to flower. 
They enclose several orange larve of a Cecidomyia (probably C. 
; Loti De Geer), At Murcar, near Aberdeen, in August. 
Astragalus hypoglottis L. (— Purple Milkvetch).—The gall consists of 
the leaves of the terminal (or axillary) buds, the leaflets of which 
remain folded (conduplicate), and become hard, fleshy, and some- 
what inflated; externally they are light green, and usually are 
covered with whitish hairs. Each leaflet is inhabited by one or 
more larve of Cecidomyia (Onobrychidis, Bremi?). The galls are 
conspicuous as they form masses sometimes over 4 inch in dia- 
meter, sometimes so compact that the individual leaflets can be 
made out only with some difficulty. They are abundant on the 
: coast south from the bay of Nigg. 
Vicia sylvatica L (—Wood-vetch).—The galls consist of individual leaf- 
lets, which are affected as in the last species, but less markedly 
so; the swelling and thickening is but slight; their colour is 
' reddish-brown, tinged with green. Frequently several leaflets 
on one leaf are affected, and it is usually the middle leaves that 
are attacked. Each leaflet contains several white larve of 
: Cecidomyia (Onobrychidis Bremi?) Not uncommon at Muchalls 
. in August. 
Vicia Sepium L. (= Bush-vetch).—The galls like those on Astragalus 
hypoglottis, form a terminal mass, the leaflets in which are folded 
upwards, inflated, hard, fleshy, and green, or greenish-yellow. 
Each contains one or more white or orange larvae of Cecwdomyia 
(Onobrychidis, Bremi?) I have found these galls on V. sepiwm 
at Banchory-Ternan, and at Braes of Gight in Fyvie. 
Vicia Cracca L. (Tufted-vetch)—A. gall quite similar to that just de- 
scribed on V. sepium. I have found it near Aberdeen, at Muchalls, 
and at Ballater.
