In addition to these records for which specimens have been examined, 
the following published records have not been verified by actual study 
of specimens: Cockerell (3) reports the species from Tetnpe, Ariz., in 
1902. Newstead (4) describes this species as new under the name Sphae- 
tococcus d.TQ.p6Tt from the Government Gardens, Delta Barrage, Ivgypt, in 
1906, and his description was reprinted with comments in the Agricul¬ 
tural News (5) for the same year. Draper (6, p. 12) lists this species 
under Newstead’s name in the same year and states that it is common 
throughout lower Egypt. Cockerell (7, p. 191-192) again reports it 
from Tempe, Ariz., in 1907. It is discussed from the general locality 
of Algeria by Trabut (9, p. 68) in 1910. Lindinger in 1912 (n, p. 247- 
248), and again in 1913 (17, p. 68 9 ) reports the species from Algeria, 
Tripoli, Egypt, and Italy. 4 Essig in 1913 ( r 9> P- 94) and again in 1915 
( 2I > P- 1:23-124 ) notes its occurrence in Riverside and Imperial Counties 
in California, as does Cook (20) in 1914. The Notice of Quarantine No. 
6 of the Federal Horticultural Board of the United States Department 
of Agriculture (13) gives Riverside and Imperial Counties in California, 
Yuma, Maricopa, and Pinal Counties in Arizona, and Webb County in 
Texas as localities where the coccid now occurs in the United States. 
Forbes (16) in connection with a discussion of the control of date-palm 
scales gives Phoenix, Ariz., as a place where this species occurs; and, 
finally, Pierce (22, p. 162) in 1917 lists it from Algeria, Egypt, and Sahara 
as among the dangerous insects likely to be imported into the United 
States. 5 All of these published localities are indicated on the accompany- 
1 Federal Horticultural Board (Port ol New York) accession number, unpublished. 
2 Federal Horticultural Board (Washington, D. C.) accession number, unpublished. 
3 Foreign Seed and Plant Introduction accession number. 
4 Em dinger ( 14 ) says (translation) ‘ ‘reported once fromltaly.” It has not been possible thus far to locates 
this report in any other coccid literature, and Eeonardi (22) fails to include the species in his list of Italian 
Coccidae published in 1917. 
6 In an article appearing after the preparation of this description Buxton (25) notes the occurrence of 
this insect in Egypt and Algeria, its importation and establishment in California and Arizona, and his 
failure to locate it in Mesopotamia where he made an investigation of date-palm insects. He gives a 
fairly extended discussion of its habits and calls attention to a paper by Trabut (12) describing an Algerian 
disease of date palms caused by this scale insect.
