purplish or reddish-purple in the old ones, while the 

 younger ones are lighter, the newly-hatched ones being al- 

 most colorless or straw-colored. 



The eggs are bright red in color and are deposited 

 mostly on the under side of the leaves in proximity to 

 the midrib. They are attached to the leaf by a number 

 of silken threads attached to a stalk fastened to the egg 

 at right angles on the upper surface. Eggs hatch rather 

 irregularly, but generally take between one and two 

 weeks. As soon as the young are out of the shell, they 

 commence to such the juices of the plant and continue 

 feeding throughout their whole existence. 



Remedies. The insect disappears in Florida with the 

 coming of the rainy season, but much damage is wrought 

 in all citrus districts during dry weather. Spray with 

 formulas (14) and (11) alternately every two or three 

 weeks until damage ceases.
