﻿THE CITRUS MEALY BUG 291 



Two years ago the mealy bug was re,ported in two orchards in Santa 

 liarbara County, but to date Mr. C. W. Beers, Horticultural Commissioner,

 mealy bug (Pscudococcns citri Risso) as simply a troublesome greenhouse 

 jiest, which would scarcely be able to thrive in the orchards, though it was
