Descriptions are given of Contarinia jyyrivora, Ril., and of the 

 injury caused by it to young pears. The collection of damaged 

 fruit and the cultivation in autumn of the groimd beneath the 

 tree or covering it with caustic lime or kainit, or watering it with 

 carbolineum, are the measures advocated.

The apple must be added to the plants attacked by the Chalcid, 

 Syntomaspis pubescens, Mayr, it having been found in apples of the 

 1915 crop in Swabia.

In addition to being present in Himgary and Russia, Syntomaspis 

 druparicm, Boh., is also found in the larval stage in small apples in 

 Styria and northern Austria, where there is one annual generation. 

 The identity of this pest with S. pubescens has not yet been established.

The red ant, Oecophylla smaragdina, ¥., is of universal occurrence 

 in Java and when present in large numbers in coffee and Hevea 

 plantations its bite is so troublesome to the workers that its 

 extermination becomes necessary. The destruction of the nests by 

 plunging them in hot water is the only reliable remedy.

The increased cultivation of oil-producing plants in Germany favours 

 their insect enemies and the most important of these are therefore 

 briefly described in this article. 



The larva of the beetle, Psylliodes chrysocephala, L., winters in rape 

 and beet crops, feeding on the pith of the stems. From May onwards 

 the adults feed on the leaves and shoots and in autumn they some- 

 times destroy entire fields of winter rape and beet. Oviposition
