218 CKYPTOCOCCUS FAGI. 



Surrey. It is common at St. Albans, King's Langley, 

 and Tring, and on the south coast Mr. T. Shepheard 

 has found it common in the Bournemouth district. 



Quite recently Mr. AY. Cooper has written to me in 

 reference to the extensive injury which this coccid is 

 causing to the beech trees on the Dropmore Estate, 

 Maidenhead, which joins Cleveden on the west. Other 

 recently discovered localities are Lancaster, " infesting 

 a large number of trees in the neighbourhood" (AVyatt) ; 

 Hexham, " it is found here upon beech from 150 to 200 

 years old, and was first noticed upon them eight years 

 ago, when they looked perfectly healthy ; since then it 

 has made steady progress, and the trees named above 

 are now nearly dead " (Robson) ; Hertfordshire (exact 

 locality not given), " it spreads rapidly, and results in 

 the death of the tree " (Dicksons, Chester) ; Matlock, 

 sparingly (Tomlin). 



Distribution. Probably occurs in many parts of 

 Europe, but has not been very generally observed. It 

 occurs in Germany (Barensprung and Beh), and Dr. 

 Sulc has met with it plentifully in Bohemia. 



Remedies. The formula recommended in Vol. I, 

 p. 59, of soft soap and water, is an excellent wash 

 for this pest, but its effectiveness depends entirely 

 upon the thoroughness of its application. It must be 

 applied with a rather long-haired scrubbing-brush, 

 which, for convenience, may be attached to a short 

 handle. The more thoroughly the wash is scrubbed 

 into the crevices of the bark the more effectual will be 

 its application. Spraying the infested trees with this 

 or any other kind of insecticide, however strong, would 

 have very little effect upon this insect, which is so 

 thoroughly protected by its thick, white, waxy coat. 



One of the most drastic measures with which I am 

 acquainted is that given by my friend Mr. A. T. 

 Grillanders,* who says : " A most interesting and 

 successful remedial measure has been brought under
