Insect Pests. 



Xewstead (1) records finding it in Delamere Forest on birchj and 

 in Cheshire it has been found on willow. Newstead also records it 



[F. Edenden. 



FIG. 311. WHITE OR WOOLLY TINE SCALE. 

 (Pulvinaria citix.) 



from Chichester, Doncaster and near Maidstone, from Stonehouse, 



Devon, and records it as being common on peach in a few localities 



in Cheshire. 



Douglas has found it on birch at Lewisham and records it from 



Hereford on vines. Specimens have been sent me from several 

 localities in Middlesex and Surrey and 

 two from Kent, all on vines and peaches 

 under glass. Fernald (2) records it from 

 the United States. 



The young female resembles the 

 Peach Scale (Lecanium persica?), later it 

 becomes transversely wrinkled with a 

 deep cleft at one end with a median pale 

 ochreous or deep brownish-red line and 

 the edge of the scale turned upwards, and 

 a dense pad of white wool appears forcing 

 one end of the insect away from the sur- 

 face of the plant, and the female becomes 

 more wrinkled and often, I find, of a 



leaden-grey colour. It is figured natural size. 



The larv?e have two anal seta? which are about half the length of 



the bodv.
