PLATE 15. 

 A branch of Corylus Avellana Linn. 



(One-fourth nat. size.) 

 Galled by 



Eriophyes avellanae Nal., var. ? 



The specimen illustrated on opposite page is another re- 

 markable example of the work of this species of mite. While 

 searching along a roadside hedge in Hollington, near Hastings, 

 the author discovered it. 



The branch formed part of a low, stunted, and irregular- 

 shaped bush. Several other branches were galled in a similar 

 manner, but not to so great an extent as this one. No other 

 bushes of Corylus Avellana were within several yards' distance. 



It was removed during the month of March. 



The 3-in. measure will assist the reader to form an idea of 

 the natural size.
