bud-scales on raised fleshy bases, which are developed into 
leaves towards the apex of the gall; a bunch of crippled, 
densely-crowded leaves grows out of and completely fills the 
mouth of the cup. The vertical section generally shows 
distinctly that the axillar part of the bud has not been 
developed in a longitudinal direction, but has been trans- 
formed into a cup, from the interior of which emanate the 
undeveloped leaves; and we further see that inner galls are 
sometimes formed from such leaves, and sometimes are 
developed from the axis, which proves that, strictly speaking, 
the gall of this species neither belongs to the true leaf- nor to 
the true bud-galls. The wall of the gall is at first sappy, but 
gradually hardens and becomes dry. It is difficult in some 
cases to distinguish this gall from that of A. multiplicatus. 
The flies emerge during the first fortnight of June.—G. L. 
Mayr. 
Dr. Giraud, who found this gall on Quercus cerris at the 
end of May, but rarely, thus distinguishes it. Near A. multi- 
plicatus, but “elle est toujours plus précoce, sa forme est 
mieux déterminée et elle n’est pas couvert des nombreux 
plis de la feuille qui distinguent cette derniére.” One 
inquiline and one parasite are recorded from it by Dr. Mayr 
in Synergus thaumacera, Dalm., and Megastigmus dorsalis, 
Fabr., both of which occur in the summer. Another Turkey- 
oak species not occurring in Britain.— £. A. Filch. 
60. Andricus nitidus, Gir.—Of this species I have but one 
specimen, collected by Von Haimhoffen, 
which I have had figured for want of a 
better, though it differs somewhat from the 
usual shape. According to Giraud the gall 
adheres to a side vein on the under side of 
the leaves of Quercus cerris, has a very 
short and slender pedicle, is spherical (the 
specimen figured is oviform), with a dia- 
meter of from four to six millimetres, is 
light green, and clothed with very short but 
thick matted hairs. The wall of the gall is 
moderately thick, of a spongy substance, 
and surrounds the larva-cell. Lt appears in October, and 
falls in about three weeks, but preserves its freshness for 
some time when on the ground: it gradually becomes gray, 
ANDRICUS NITIDUS.
