The typical condition of the gall is imilocular and uuilaival. 



The larva pupates in the gall. The imago emerges during 

 the autumn.

The specimens shown in the plate can hardly be 

 considered as typical of this species. They were not 

 fonnd nntil past maturity, and the leaves were begin- 

 ning to wither ; consequently the galls are slightly 

 above the average normal size, and fewer in number 

 than is usual. 



In the Hastings district they are rare, and no other 

 specimens have been found that would serve the 

 purpose of an illustration. 



This species is not mentioned in ' Alternating 



Fig. 11. — Sections of galls caused by (a) Dryophanta agama, (b) D. disticha, 

 (c) D. divisa. All "x 2. Dele, ad nat. E.C. 



Generations,' and very little is recorded about it in 

 anv treatise on o-alls. 



The galls are found mostly on oak bushes in woods, 

 and stunted growths along hedge banks. One year 

 they may be numerous, the next, scarce, and no reason 

 can be assigned. 



Their normal position is on the offshoots of the mid- 

 rib ; they are, however, occasionally attached to that 

 also. They vary in number on a leaf to as many as 

 ten, seldom more than twelve. 



In shape they are oval, or ovoid, occasionally 

 globular, much flattened next the leaf. They are 

 attached by a very short, but stout, peduncle. The 

 position of attachment does not show on the upper 

 surface of the leaf.
