also P. maritimus Ehrh. and P. adonidum L. Liberations of Crypto laemus 
montrouzicri Muls. were necessary" in some, parts of Los. Angeles County for 
these species. The citrophilus mealybug (P.. gahani Green) lias been scarce 
all season with no damage reported. This is believed entirely/- due to the 
Australian' -parasites Coccophagus gnrneyi Comp. and Tetra.cnemus pretiosiis Tittb., 
sucessfully introduced by the University of California Citrus Experiment 
Station. 
BLACK SCALE ( Saissetia oleae Bern.) 
California. H. J. "Ryan (September 26):' The black scale was fully 30 days late 
in completing its hatch throughout Los Angeles County. Ordinarily fumigation 
can be started in some districts by July 1. This year the delayed hatch 
made it necessary to postpone treatment until after August 1. Areas where 
work ordinarily begins July 15 were not able to start until after August 15. 
CALIFORNIA RED SCALE ( Chr-somphalus aurantii Mask. ) 
California. H. J. Ryan (September 26): Infestations are lighter this' season 
•as compared with the last three years. This is generally thought to be due 
to normal cool temperatures last winter which evened the broods so- that 
control measures this season were more effective than in previous, seasons. 
COTTONY- CUSHION SfiAIE (Icerya pure ha si Mask. ) 
Georgia. J. B. Gill (September 25): Within the past three weeks we have had 
several reports of infestations in various localities in southern Georgia. 
Ornamental plants, especially Fittosporum and spira,ea, are infested. 
CITRUS WHITEFLY ( Dialeurodes citri Riley & How. ) 
California. H. J. Ryan (September 26): A new infestation was found by survey 
crews in August about 4 miles northeast of the Pasadena infestation found 
last summer. Infestations were found on two adjoining city blocks. Detailed 
survey of the entire Pasadena area has not been completed and it seems probable 
that the existing infestations have been limited.
