 Observed in Germany, but the mite has not been identified. 



Lin ARIA VULGARIS. Leaves rolled or folded at the margins, 

 often bent and puckered. Beddick, Mr. E. Bagnall, September, 

 1915. Similar galls have been found in France and Germany, and 

 are supposed to be caused by mites. 



Veronica Cham^drys. Stems, petioles, and leaves bearing 

 tumours of variable size. Dr. Ernest J. Schwartz reports these 

 galls from Swanage. They have been observed in Germany, and

 elongated larval cavity in the pith, with a small circular opening 

 through the bark. [Hymenopteron ?] Penshaw, E. Bagnall,

 stems of knapweed (in France and Germany), but live in the wood 

 beneath the bark, not in the pith.
