showed that in dry weather living adults and brood of S. Jimnpei occuiiGd, 

 even after a period of 2 months, m infested berries lying on the ground. 

 This is of great importance in connection with the question whether 

 the removal, at one and the same time, of all infested material should 

 be advised agamst this pest. From one estate, lamtoro [Leucaena 

 glauca] mjured by bark-beetles was received, the infestation being 

 believed to be prmiary.

Nearly all the Hymenopterous parasites reared from Antlioynonus 

 'pomorum infesting the apple in various parts of Holland appear to be 

 Bracon discoideus, Wesm. It is not improbable that B. discoideus had 

 Bycliscus hetulae as its original host, from which it later adapted itself 

 to A. pomorum. As B. discoideus is known to have been bred from 

 the saw-fly, Pontania proxima, Lep., the introduction of the latter's 

 food- plant, Salix amygdalina, into districts infested with A. pomorum. 

 might be worth trying.

Bracon variator, Nees, has been bred from cocoons found in pear 



infested with larvae of Hoplocampa sp., probably //. brevis, Htg. 



Bracon scutellaris, Wesm., which is new to the Dutch faima, is recorded 



from fir-cones.

From a cocoon collected in the winter of 1918-19 a female example 

 ' of Diprion {Lophyrus) nemorum, F., emerged on 2nd August 1919. 

 This seems to show that there is only one generation of this saw-fly a 

 year in Holland.
