SicnolccJiia gciivuella, L. [Poccilia nivca, Han.), previous!}' recorded 

 in Switzerland, spread during 1919 throughout the country on Quercus 

 robitr. It causes thickening of the twigs for a length of 2-6 cm. at 

 their ends, the caterpillar being found within the swelled portion. 

 There appears to be only one generation a year.

Baker (A. C). Anuraphis longicauda, a new Aphid injurious to 

 Plum Trees. — Proc. Biol. Soc. Washington, D.C, xxxiii, no. 20, 

 30th December 1920, pp. 93-95. 



The stem-mothers of Anuraphis longicauda hatch about the 1st 

 April, and begin reproducing about 24th April. Apterous viviparous 

 females occur throughout the summer in all generations. The winged 

 viviparous forms appear in the first generation after the stem-mother, 

 after which they may be found throughout the season. 



This species is recorded as injurious to plum trees in Virginia, 

 Nebraska and Montana, both the twigs and leaves being attacked. 

 The eggs are laid in the autumn on the twigs.

 Bark-beetle.] — Schiveiz. Zeitschr. Obst- und Weinbau, Fratienfeld, 

 XXX, no. 1, 8th January 1921, pp. 6-9, 1 fig. 



Examination of a prune tree, of which the upper lialf was infested 

 by a small bark-beetle, Scolytus [Eccoptogastcr) ritgulosns, showed that 

 the lower half was infested by fungi [Fitsarinm sp., Clastcrosporiiim 

 sp., and an unidentified species) that had evidently gained an entrance 

 at the graft and had caused the death of the tree. Injury by the 

 fungi had apparently encouraged the bark-beetle, and such a focus 

 of beetle infestation may prove dangerous to neighbouring trees that 

 are free from fungi.
