Gall. These little kidne3^-shaped galls, generally 

 found in great numbers on the under side of the leaves, 

 are arranged in rows attached to the veins. The 

 gall is of a green or yellowish colour sometimes tinted 

 with red. It is formed in September, attains maturity 

 in October, and then falls to the ground. (Fig. 18.) 



Notwithstanding the enormous abundance of the galls, 

 attempts at rearing do not always succeed. When the 

 galls fall in October, the larva has not attained its full 

 growth, and they must therefore be kept on damp sand.
