DRYOPHANTA LONGIVENTRIS. 113 
inability to flatten the gall with pressure between the 
thumb and finger. 
Many specimens are spherical. The normal con- 
dition is slightly longer than broad, and distinctly 
flattened at the top and bottom. It is attached by 
a short, but stout, peduncle. 
The usual number on a leaf is about 10 to 15, but 
25 to 35 is not unusual. On one occasion I found 
three leaves, all on one stem, bearing 32, 32, and 35 
galls. In some seasons they are in such profusion 
that their weight causes the leaves to hang down 
considerably. They are often found in company with 
either, or all, of the Newroterus species on the same 
leaf. 
The name “red pea gall” is indicative of the 
beautiful colour with which nearly all specimens are 
suffused during development; when mature the red 
fades, leaving a pale, but pleasing shade of brown. In 
common with all the globular oak-leaf galls, they 
normally remain attached to the leaf all through the 
winter, although that may have fallen after several 
frosts.
