other countries, but is seems to be only really dangerous to agriculture 

 in Austria, Rumania, and especially Russia, Under normal conditions 

 the first insects appear at the beginning of April and there is 

 only one generation a year. L. cyanella, L. {lichenis, Voet.) is also 

 known in Hungary as an injurious insect, but is less common.

The appearance of Pidvinaria vitis in Uruguay in November 1914 is 

 reported — it is beheved for the first time. Serious damage was done 

 in the vineyards. Information is given on the morphology and 

 biology of this scale and on the usual methods of control.

This paper is a detailed account of the author's work in the district 

 under his charge in the anti-locust campaign in 1915. The main facts 

 and conclusions obtained in the campaign have been dealt with in a 

 joint report [see this Revieiv, Ser, A, iv, p. 45]. All the birds in the 

 region preyed upon the locusts. In May numerous pupae of Anthomyia 

 were noticed, other parasites being the larvae of Cebrio and Anthrax 

 fenestrata. In June, pupae of Stomatorrhina (Idia) fasciata, larvae 

 and adults of Staphylinids, and Oligochaetes, were all present in 

 numbers. In the Sebdou region the infection was not fatal to Schisto- 

 cerca peregrina ; this failure is thought to be due to the presence of an 

 indigenous infection, caused by two distinct bacteria of the same 

 group as d'Herelle's virus, which apparently rendered the insects 

 immune to the American form.
