removed and replaced with rich soil and the weevils were searched for 

 •daily. The vines were treated with ammonium sulphate and 40 per 

 •cent, potash salts. This treatment must be carried out repeatedly 

 during the summer and stable manure should not be used in the years 

 following. Puhinaria vitis may be controlled by thorough scrubbing 

 and spraying mth a 15 per cent, carbolineum solution. Nysius 

 senecionis was recorded for the first time as a vine pest in Germany at 

 Walporzheim, where, owing to lack of food, it migrated from Senecio 

 vulgaris to the vines. Cydia pomonellu and C. funebrana are specially 

 ■dangerous in Rheingau because they have two generations ; the second 

 generation of moths occurs in August and is usually more numerous 

 and harmful than the first. The first appearance of Cheimatohia 

 brumata is usually between 28th October and 4th November. Sparrows 

 do useful work in destroying this moth, especially at nesting time. 

 The raspberry beetle, By turns fumatus, was noticed on apple blossoms.

In the dry autumn of 1914 large numbers of a mite, Phyllocoptes 

 Jockeni, appeared on Primus dmnestica. Many of the insecticides tested 

 proved ineffective. Kellers spray for Aphids only gave insufficient 

 results, and both " katakilla " and " contraphin," prepared by Messrs. 

 MacDougal, of Manchester, rec^uire to be used at a greater concentration 

 against plant lice than recommended in the instructions.

A detailed description is given of the occurrence of Cepkaleia abietis, 

 L. {Lyda hypotrophica, Htg.) in the forest of Roggenburg, Suabia, and 

 the damage it has occasioned of recent years. The observations were 

 made in the Royal Forest of Breitenthal, but are typical of the whole of 

 8uabia. In August 1911, in a stand of Epicea 119 years old, many 

 trees were remarked with their tops and sides entirely stripped 

 of needles. The injury was at first ascribed to the excessively 

 dry weather, but on felling the trees, it was found to be due 

 to this sawfly. Stands of from 60 to 1 20 years old suffered most, as 

 the majority of the larvae generally live in that part of the soil which 

 is shaded by the largest trees. A series of observations were made as 

 to the average number of larvae present in the soil. No stand 

 throughout the Royal Forest District, comprising 5,683 acres; was 

 entirely free from larvae, independently of the age of the trees. Taking 

 100 as the basis of the number found in 1911, this had fallen 19-5
