276 Coco-nuts The Consols of the East 



Paralecaniiim cocophyllce (Banks). This 

 always occurs upon the inferior surface of the 

 leaf. The male puparia are much scarcer than 

 those of the female. 



The best remedy for such pests is to watch 

 for and remove all malformed and defective 

 leaves, and to destroy trees suffering from 

 beetle attacks, as these tend to attract them. 

 Those trees which are the healthiest and best 

 cared for are the ones which will best with- 

 stand the pests. Spraying with lime-sulphur 

 and emulsions do good ; the soap and oil in 

 the latter form a skin over the insects, and so 

 smother them. 



The larvae, pupae, and adults of Silvanis 

 surinamensis (Linn.) and Necrobia mfrpes (De 

 Geer) attack copra. Carbon bisulphide might 

 be used successfully, but would probably prove 

 detrimental to the copra owing to its power 

 of dissolving oil. Mr. Banks includes excel- 

 lent illustrations of all these pests, and of the 

 trees, leaves, &c., attacked, as well as a biblio- 

 graphy of work and reports published up till 

 then on the question of diseases, making 

 these two issues (January and April, 1906) of 

 the Philippine Joitrnal of Science invaluable 

 to anyone studying coco-nut pests. 



According to Progress Report LVIII, 

 dated March 7, 1912, of the Ceylon Agri- 

 cultural Society, Mr. Madanayake, Agricultural 

 Instructor, reported on the diseased condition 

 of large patches of coco-nuts near Padukka
