Lifehistory. The flattened "Green Bugs" are found on the 

 tender twigs and leaves, usuall) along the veins on the underside of 

 the latter. The presence of these scales in large numbers gives rise 

 to .1 black FungUS which develops on the Honeydcw falling on the 

 upper surfaces of the leaves, and this usually attracts attention to 

 the scales, which arc not verj conspicuous. 



Foodplants. -Coffee, principally. Also on Guava, Loquat, Cin- 

 chona, etc. 



Status. -A very serious pesl ofCoffee but the an 

 done seems to depend on local conditions or on causes not yet 

 understood. In some districts the Coffee has been absolutely wiped 

 out by the attack of this scale, whilst in other districts, where it 

 occurs commonly, comparatively little dan • to result. 



("in - ind Brushing of leaves where practicable. 



But this scale requires detailed study before any method can be 

 recommended definitely and methods applicable will probably 

 require modification to suit local conditions.
