Xewstead (1) says the second generation of the White Woolly 

 Scale becomes infested with these minute hymenopteru, which 



increased in the third generation under oljservatiou to such an extent 

 that 50 per cent, of the Coccids were destroyed. This parasite is 

 known as Blasfoihi'i.i: scr/ccd (Dalman), 



Many scales are destroyed by the Tits {I'driiJa:), especially liy 

 the Blue Tit (Fui-i/s roji'ii/iti.^); but as they also help to spread several 

 of tliese enemies I am afraid that much of the good they do is counter- 

 balanced. Xewstead also mentioirs the Cole Tit (7'. «/'/'), the Marsh 

 Tit (/'. iiiiliis/i'is), and the Great Tit (/'. iiiajor) as feeding ujion them.
