 caused hj Sriojihi/rs rihis. Ormerod describes the galled buds (1) as 

 drying up and falling ofl'. I have never yet 

 seen this ; old buds of the preceding year ai-e 

 of common occuri'ence on tlie nut. 



The mite is about 0'21 mm. in length in 

 the female, 0"18 mm. in the male. The 

 fenrales lay their eggs in the buds in the same 

 way as the currant species does, and as the 

 old buds decay they nrigrate to otliers. In 

 July and August a second growth becomes 

 prominent, easily noticed by tlieir size and 

 often bright colouring.

 winter. 



Nalepa's figure of 

 the mite is reproduced

 mucli fatter and rather 

 broader thair the 

 female ; in colour they 

 are very similar to the

bristles tov\'ards the head, followed by two 



long ones close to them ; then are seen two 



long and two small caudal setie ; veutrally 



are three pairs of short seta' in both male and 



female. The ova are more lien's egg shaped 



than those of E. rihix.
