The coffee berry-borer [Stephanoderes hampei] occurred on many 

 estates, having been previously noted on one only in the Salatiga 

 district. One planter is testing the effect of smearing the berries 

 with an adhesive with the object of killing borers within them and 

 of capturing individuals seeking to attack healthy ones.

Myelophilus {Blastophagus) piniperda does not always mate in the 

 open. The mating chambers, which are best seen in mines made in 

 March and April and lie partly in the bark and partly in the sapwood. 

 are described.

It is reported from Bohemia that the nun moth [Liparis monachal 

 has attacked fruit-trees to such an extent that the defoliated branches 

 died. Apples suffered most, pears less, while plums escaped. Larvae 

 placed on plum trees migrated to others.

 p. 6.) 



During the outbreak of the pine moth, Bupalus piniarius, in Galicia 

 in 1915-17, trees in high situations suffered most from defoliation. 

 Up to 1,000 caterpillars were counted on one trunk. Artificial measures 

 were hopeless. The author studied the following parasites : — Hetero- 

 pelma calcarator, Wesm., Ichneumon nigritarius, Gr., Lydella nigripes. 

 Fall., Parexoristes rutila, Rond., and, more particularly^ Anomalon 

 hignltatum, Gr., which was a factor in checking the infestation. 

 Development in this Ichneumonid only requires 8-10 days, a constant 

 degree of moisture being necessary. In the winter of 1916-17 

 27 per cent, of the pupae were infected with a fungus, Botrytis 

 bassiana. The pupal stage lasts 2-3 weeks.

Euxoa {Agrotis) segetum is a dangerous pest of sugar-beet in Czecho- 

 slovakia. It is favoured by heat in summer and autumn. Its 

 natural enemies include a fungus, Tarichiuni megaspermum, which
