This, like the preceding one, is a very common species on citrus trees 

 in Florida. It infests the leaves and the bark of the trees, and is usu- 

 ally associated with the purple scale (Mytiiaspis citricola). This species 

 is said to have been introduced into Florida about forty years ago, on 

 some trees purchased of a ship in New York from China, and from those 

 trees the scale has spread. 



Description. The body of the female is light purple in color. The 

 scale differs from that of Mytiiaspis citricola, in being much narrower; 

 is light yellow, and varying to dark brown. The eggs are white when 

 first laid, but become tinged with purple before hatching, and are 

 arranged in regular rows. The young larvae are purplish, the front of 

 the head and the margin of the body light yellow.

Figure III represents a branch infested with the scales. 



This insect is not often met with, neither is it a very troublesome pest. 

 It is not a common species, and is only found in patches. I found this 

 scale on soft wooded plants in gardens and parks, and only saw it on a 

 few orange trees. An Inspector in Los Angeles, however, showed me a 

 number of specimens which he had taken from orange trees imported 

 into that county from Florida.
