DBYOPHANTA LONGIVENTEIS. 113 



inability to flatten the gall with pressure between the 

 thumb and fino-er. 



Many specimens are spherical. The normal con- 

 dition is slightl}' 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 Neuvotevui^ species on the same 

 leaf. 



The name " red pea gall " is indicative of the 

 l)eautiful 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.
