the Imperial Valley, work was confined during the fiscal year 1930 to the 
southern part of the county, the only area in which infestation had previ- 
ously "been found. Ninety-two infested palms were discovered on 30 
properties as contrasted with 1,115 infested palms found on 60 properties 
during the previous year. In the vicinity of Phoenix in the .Salt Paver 
Valley of Arizona, 27 infested palms were found during the fiscal year 
on 5 properties, as contrasted' with 43 infested palms found on 12 proper- 
ties in 1929. In the Yuma District, 8 infested, palms, all ornamental, 
were found on 3 properties during the year. Commercial plantings in this 
area were kept under observation hut no scale was found in them. The 
Fr.rlatoria date scale has not "been found in Texas for a number of years," 1 
C I T50 PHILUS MEALYBUG 
The situation with regard to the citrophilus mealybug ( Pseudococcus 
gahani Green) in southern California was more favorable than it has been 
any year since the insect became a major pest in that section of the 
.-State. Only a very small percentage of the properties were reported as 
heavily infested. 
0THE3 CITTiUS INSECTS 
The dry weather that prevailed over parts of Florida was accom- 
panied by decided increases in the populations of the Florida red scale 
( Chrysomphalus ficus Ashm. ), the purple scale ( lepi do sa^he s b ecki i Uewm . ) . 
and the citrus whitefly ( Dialeurodes citri Ashm.). The reporter be- 
lieved that the lack of humidity prevented the development of the ento- 
mogenous fungi which normally check these pests. 
MEXICAN BEA1T BEETLE 
The Mexican bean beetle ( Dmilachna corrunta Muls.) was observed 
emerging from hibernation in the Norfolk district of Virginia and in 
Delaware during the first week in May. During the last week in May and 
the first two weeks in June the insect was observed throughout the 
northern part of the territory known to be infested/ Throughout early 
July, the insect was quite generally reported throughout the infested 
territory, though infestations in the northern part of its-range did 
not seem to be so serious as they were in 1923. - The hot, dry weather 
that prevailed over a large part of the eastern part of the United 
"Sto.tes appears to have been very destructive to this insect and over 
much of the territory it practically disappeared as an economic factor. 
In Massachusetts the insect was found during the year to be well dis- 
tributed over the Connecticut River Valley district northward into 
Hampshire County and has been found in a few instances in Franklin 
County. Otherwise, there was but little extension of the territory 
known to be infested.
