THE SAX JOSE OR CHINESE SCALE. 
repeatedly reared from the San Jose scale, but it is also known to 
attack Chrysomphalus flcus Ashin. and C. aurantii Mask, variety 
citrin us Coq. It has made its way to the East and has been reared 
from the San Jose scale received from Hampton, Fla.. where it was 
collected by Mr. A. L. Quaintance. This species seems to be found 
only in the warmer countries, and has not been found north of Florida 
in the East as yet. 
Anaphes gracilis Howard, which was reported in Bulletin No. 3 as 
originally reared from specimens collected at Riverside, Md.. and 
later from twigs received from Charlottesville, Va., has not again 
been reared in this office from the San Jose scale, and the doubt 
exprest in our original note ma}" be valid, namely, that this species 
may have been a parasite of some other scale insect, probably the 
oyster-shell scale, present on the twigs at the same time. The type 
of the species was reared from the oyster-shell scale of the apple, and 
it is quite likely to be an egg parasite only. 
Fig. 7.—Aspidiotiphagus citrinus, greatly enlarged (from Howard). 
The four species just mentioned were recorded in Bulletin No. 3. 
During the summer of 1905 three other species have been reared by 
Messrs. Quaintance and Girault. These are as follows: 
Physcus varico?*nis Howard was reared from material collected by 
Mr. Quaintance, May 30, 1905, at Hampton. Fla. There remains a 
little doubt as to the parasitism of this species on pemiciosus z as 
according to the note there may possibly have been other hosts present. 
The known hosts of this species are Aspidiotus ancylus Putn., Ch'<<>n- 
aspis qut reus Comst., and Chionaspis americana Johnson. 
Prospalta aurantii Howard (tig. 8) was reared from the San Jose 
scale July 31, L905, from material collected from an infested pear tree 
on the grounds of the Department of Agriculture, at Washington. 
This parasite affects no less than nine distinct species of scale insects, 
and has been reared from material collected in California, Florida, 
District of Columbia, New York, New Mexico, and Illinois.
