A leaf-gall caused by a moth. 



Thèse galls are situated on 

 the undersurface of the leaves, 

 being mostly directed in the long- 

 itudinal axis of the offsprings 

 of the main-nerve. The gall is 

 bean-shaped fastened to the leaf- 



blade by the concave side. On the transverse 

 section they are circular, the longitudinal 

 section showing oval. The uppersurface 

 shows only a little oval dépression. Internaliy 

 it contains a long narrow larval cavity in 

 the longitudinal axis of the gall. 



A similar gall has been described on 

 Glochidion molle Bl.
