 Rico, South America and probably elsewhere.

 shade. It also occurs on the Christ's Thorn and Sunt. 



Coccus (Lecaniwri) viride Green., the so-called green bug of Cey- 

 lon, infests a long series of useful plants, but is especially destruc-

Leucaspis japonica Ckll., occurs in Japan, China, and South 

 Africa, infesting apple, pear, maple, magnolia, etc.
