Appearing below buds on the twigs and branches. Gall 
spherical, 12 to 23 mm. in diameter, at first green, then 
yellow, finally brown, often sprinkled with little nodosities. 
Its parenchyma is yellowish-brown, firm, but easily cut 
with a knife. It appears from the side of a bud which 
remains intact. Solitary, gregarious or coalescent. Imago 
appears in August or September. Said (by Beyerinck) to 
be the alternate generation of Andricus circulans. (Text,

Cupule affected. Gall the shape of a truncated cone, 
15 to 20 mm. high, fixed to the cupule by a broad base 
25 mm. in diameter ; substance woody, coloured like the 
cupule. Its surface is marked with 5 to 8 keels, often inter¬ 
rupted by depressions; those at the apex surround a 
circular hole giving access to a chamber—below which is 
another cavity, entirely closed, containing the internal 
gall and larva. Imago, February or March, II. This gall 
has been recorded from Jersey, Channel Islands, but not 
from the United Kingdom.
