Contrary to the original plan [R.A.E., A, ix, 479], it has been found 

 necessary to devote two parts of this handbook to the description of 

 summer measures against insect pests, each part being again subdivided 

 into two sections. 



The present section contains information and instructions for the 

 collection and preservation of insects. 



The second section will deal with the bionomics of insects, their 

 economic importance and the interrelation between them and other 

 animals.

A detailed account is given of the life-histor}^ and habits of Pieris 



brassicae, L. [cf. R.A.E., A, ix, 552], with particulars of the better 



known remedial measures and a list of the twenty-six parasites of 



this butterfly that have been recorded by various authors.

In some parts of central and south Italy Lytta vesicatoria, L., often 



causes perceptible injury to olive and other fruit trees by rapidly 



devouring the leaves and tender shoots. The only measure hitherto 



employed against this beetle has been jarring the trees in the early 



morning. 



B}^ the advice of the author this treatment has been superseded for 

 some years past, especially in the case of olive trees, by applying a 

 spray with an acid Bordeaux base (3 lb. copper sulphate and 2 lb. 

 slaked lime in 20 gals, water) to which has been added 2-3 lb. lead 

 arsenate. A single application made at the beginning of an infestation 

 has always sufficed to free the trees completely in a few hours. The 

 slight traces of lead arsenate disappear by the time the olives are 

 gathered.

[Received 7th July 1922.] 



Oryctes rhinoceros, L., is an important enemy in Goa of the coconut 



palm, which is one of the principal sources of revenue there. The 



damage it does is usually confused with that due to RhyncJwphorits
