From Barcelona the Coccid, Ceroplastes nisei, L., is recorded on 

 leaves of fig (Ficus carica), while Saissetia [Lecanium) oleae, Bern.^ 

 infests lemon trees {Citrus limonum). Cocoons of the moth, Euhlemma 

 (Thalpochares) scitula, Ramb., which is predaceous upon these two 

 species, were found accompanying them. 



Attention is drawn to the damage caused in cofTee and cacao plan- 

 tations in India by Nezara viridula, L., as this bug occurs also in 

 Spain.

This is the third instalment of reports dealing with the state of 

 viticulture in Russia in 1915, summarised on the lines of the previous 

 ones [see this Review, Ser. A, iii, p. 375 and v, p. 194] ; it covers the 

 months of August-September. No insect pests were rejDorted from 

 the majority of vine-growang districts. In Bessarabia some damage- 

 was done by Clysia ambiguella ; in Taurida by Polyphylla fuUo, 

 Otiorrhynchns and Pseudococcus vitis, against which the stocks were 

 smeared with spirit mixed with hempseed oil. In the province of 

 Don Eriophyes (Phytoptus) was present in several localities in great, 

 numbers, the same pest being also reported from the Black Sea. 

 Polychrosis hotrana, which was controlled with barium chloride, was. 

 reported from Astrakhan and Tiflis.

The greater part of the subject matter of this article has already 

 been noticed from another source [see this Revieiv, Ser. A, v, pp. 343 

 and 345]. Subsequent experimental work during 1917 has shown that, 

 the yello\ving of apple foliage resulting from the use of calcium arsenate 

 with sodium sulphide may be avoided by reducing the quantity of 

 arsenate and adding an excessive quantity of either water-slaked lime 

 or hydrated lime. One combination, four applications of which gave 

 no trace of yellowing or scorching, is composed of 2^ to 3| lb. soluble 

 sulphur (a sodium sulphide), 1^- lb. calcium arsenate, 15-20 lb. of 

 either hydrated or water-slaked lime and 100 gals, water. 



Potassium sulphide or liver of sulphur is one of the old-fashioned 

 fungicides which acts in the same manner as the sodium sulphides ; 

 it is safe alone, but dangerous when used with any of the metallic 

 arsenates. It can be used with perfect safety with calcium arsenate 

 provided that an excess of lime be present. Nicotine sulphate can 

 be used with any of the fungicides or poisons with perfect safety^ 

 but is more efficient with sodium sulphide solutions than with lime- 

 sulphur or Bordeaux mixture.
