in small masses, but both the eggs and the mites are lighter in 

 color, and the latter, under a good glass, will show six odd shaped 

 spots on the back. They make the leaves of the plant turn yellow 

 and fall, beans especially. They also infest the underside of citrus 

 leaves. 



The Silver Mite, while not known in our county, is quite com- 

 mon in a neighboring one, and should be guarded against. They 

 work on citrus trees, on the leaves, much like the Citrus Mite, but 

 on the fruit they extract the oil and coloring matter from the rind, 

 giving the lemon a silvery appearance, and a russet color to the 

 orange. 



There is also the Blister Mite which attacks grapes, walnuts, 

 pears, etc., forming blister like excretions on the leaves, but we 

 know of no trouble from it here. 



Citrus Red Spider (Tetranychus mytelaspides) Male.
