PLATE U. 

 A branch of Corylus Avellana Linn. 



(Nearly half nat. size.) 

 Galled by 



Eriophyes avellanse Nal., var. ? 



This unique specimen was discovered by the author in a 

 roadside hedge near Guestling, Hastings. 



The centre is a hard, solid, and woody mass from which 

 grow hundreds of small twigs, many of them knobbed and 

 swollen in various places. Unfortunately, it was not possible 

 to identify the species of the mites at the time the specimen 

 was found, and when the opportunity occurred they had long 

 before died and shrivelled. 



The young leaves on many of the twigs indicate that the 

 branch was removed during the month of May. 



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

 of the natural size.
