The mole is generally credited with the destruction of Melolontlia 

 tnelolontha and several authorities have stated this to be the case, but 

 a series of careful observations on this animal, both with captive and 

 free individuals, show that it is absolutely valueless in this connection.

In 1916, 1917 and 1918, Cnethocampa [Thanmetopoea) pinivora, Tr.. 

 was abundant in West Prussia, especially in some parts of the coast, 

 and it was decided to use a poison-spray to destroy it. As the cater- 

 pillars of this moth were not available for the experiments, they were 

 carried out with those of Vannessa io and Dasychira pudibunda. 

 The insecticides tested Avere carbohneum and nicotine, and they were 

 entirely successful in emulsions of 3 per cent, strength, though a 

 somewhat higher percentage is advisable.

Attention is drawn to the practice obtaining in parts of France 

 and Germany and in Carniola of protecting cabbages against Pieris 

 by placing tAvdgs of elderberry (Sambucus nigra) around the plants. 

 Hemp is used for the same purpose in Styria. In the latter case the 

 odour of the hemp plant provides a reason, but the repellent action 

 of the elderberry does not appear to admit of this explanation. 



If the protection is proved actually to exist there is perhaps a 

 possibihty of utihsing the active principle in the preparation of an 

 effective spray.

Among the Cerambycid beetles infesting Ficus elastica in Java 

 [liA.E., A, ii, 533] are Batocera albofasciata and B. gigas, and some 

 supposed hybrids between these species are here described.
