Commissioner, Harold J, 3yan, Specimens of the insect sent 
to the State Department of Agriculture, r.-ere in t - arwarded 
by that Department to Washington, D. C, -'here a positive 
identification was made. The infestation appears to be of

that grape vines in the plot found infested have been dying 
back for some: time.

been introduced into the State of California about 75 years 
ago and has spread quite v/id.ely in the northern part of the 
State, it has never gained a foothold in the south. The only pre- 
viously recorded infestation in the southern part of the State 
being in San Diego County.
