of the leaves were quite clear of infection. The removal of 

 the infected leaves was, therefore, possible, and the lime- 

 sulphur-caustic-soda wash is to be tried in the winter. The 

 other trees in the garden have not yet been infected. A 

 second case, reported from Harpenden, Herts, showed dis- 

 tinct traces of the spread of the pest. The writer stated that 

 he had thirty-seven fruit trees in his garden all free from 

 disease, except four pear trees, a Pitmaston Duchess, a Louise 

 Bonne of Jersey, a Bon Chretien (Williams), and a Duron- 

 deau, each of which was affected by the mite, the first men- 

 tioned generally, the other three very slightly. A neighbour 

 had several pear trees more seriously affected. A third attack, 

 reported from Banwell, in Somerset, is said to have been first 

 noticed in the garden this year. The Board would be glad 

 to receive information of the presence of the pest in any 

 part of Great Britain where it appears. Mr. Theobald has 

 records of it on a few leaves in gardens in Cambridgeshire, 

 Bedfordshire, Sussex, Devon, and Cornwall ; in Somerset at 

 Bruton, Bath, Minehead, Porlock and Clevedon ; in Surrey 

 at several places; in the Wye Valley at Chepstow; and in 

 Wales near Criccieth and near Dolgelly. In his opinion it 

 did not increase much till the last two or three years, but is 

 doing so now, and is very bad this year. Mr. Collinge has 

 records of attacks during 1 907-1909 at Berkhamsted (Herts), 

 Coventry and other localities in Warwickshire; in Worcester- 

 shire; at Bowden in Cheshire, Wellingborough in Northants, 

 and previously to 1907 in Lincolnshire. He believes it is 

 spreading rapidly. 



The Bud Moth (Hedya ocellana). — A case was reported 

 from the Wisbech district of this pest, which is common over 

 the South of England. Insufficient details were given to 

 judge whether it was present to any great extent. 



The Willow Beetle (Galerucella lineola). — Information 

 having reached the Board that a serious attack of this beetle 

 had occurred in Somerset, an Inspector was despatched to visit 

 the district and report. He found that a large number of osier 

 plantations in the neighbourhood of Yeovil were seriously 

 affected, and that the pest had been present in considerable 

 numbers for some three years. Many of the willows had been 

 ruined for commercial purposes; the shoots, which should
