FLORIDA WAX SCALE. 



Ceroplastes floridensis, Comstock. 



IV. 



[A white scale which appears in and throughout Florida. Has not yet made its appear- 

 ance in this State, and care should be exercised to prevent its introduction; and in order 

 that parties importing trees or plants may be able to identify it, this description and illus- 

 tration is given. Figure IV represents a branch infested with the scale, ^a) Young 

 female. (6) Adult female, enlarged.] 



This scale is a very common species, and is found on wild plants 

 mostly. The development of this scale is quite rapid. This insect is 

 no doubt indigenous to that State. The trees attacked by it do not suf- 

 fer as they do by other scales, such as the Aspidiotus and Lecaniums. 



CHAFF SCALE. 



Parlatoria pergandii, Comstock. 



This is perhaps the most common species of scale 

 found throughout the State of Florida. It is mostly 

 found on the trunks and on the large limbs of the 

 trees, covering them thickly, and is but seldom seen 

 on the leaves and fruit. This is a light colored 

 scale, and is more or less circular. When an insect 

 does settle on the fruit it occupies a pit-like depres- 

 sion in the rind. The scale is so near the color of 



^ bark f the trunk . aild lar S 6 branches that ^ is 



male, enarged.] liable to escape unnoticed.
