BITING INSECTS. 



Caterpillars of a large butterfly Brassolis 

 sophorce. 



Palm weevil Rhynchophorus palmarum. 



Giant moth or sugar-cane borer Castnia 

 licus, also C. dcedalus. 



Scale insects and white fly, we are told, may 

 attack young coco-nuts, either in the nursery 

 or in the field. If plants in the nursery are 

 attacked they should receive an application of 

 some insecticide, in order that they may be 

 rendered free from these pests before they are 

 transplanted into the field. The Bourbon 

 aspidiotus, the coco-nut snow scale, the coco- 

 nut mealy-bug, and the white fly may all be 

 satisfactorily controlled by means of an oily or 

 soapy wash, such as kerosene emulsion or 

 whale-oil soap ; while the glassy star scale and 

 the black line scale should receive an applica- 

 tion of one of the rosin mixtures. If several 

 different insects appear on the same plant, a 

 wash such as rosin compound and whale-oil 

 soap may suitably be employed for their 

 control, or possibly one or other of the 

 advertised insecticides and scalicides may be 

 found to be even more effective. 



INSECTICIDES. 



The washes just referred to may be pre- 

 pared as follows : 



Whale-oil Soap. Dissolve i Ib. of whale-oil 

 soap in i or 2 gallons of warm water.
