THE BROWN MITE. {Jh'ifoh'ui B/Y/Zr/zw/.s, Carman.) 
ddiis insect is also called “Clover Mite,” and in some lo- 
calities it is called “Red Spider” on account of the rust-red 
color, but the last name is applied to another mite treated 
on another page, d'he eggs of this insect are nearly globu- 
lar, of a bright red color, and often occur in enormous num- 
bers on the bark of pear, apple and other orchard trees, 
most often on the pear in Colorado. They give the bark a 
rusty red appearance and will stain the hand if it is rubbed 
over them.* The eggs are so small that, without a glass, it 
would be impossible to discover their real nature. During 
May they hatch and the little mites coming form theiri are.
