THE SAX JOSE OR CHINESE SCALE. 



repeatedly reared from the San Jose scale, but it is also known to 

 attack CJirysumpho.Jus ilcU'^ Ashm. and C. aurantii Mask, variety 

 citrrn 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. 



AnopJits gracilis Howard, which was reported in Bulletin Xo. 3 as 

 originally reared from specimens collected at Ri\'erside. Md.. and 

 later from twiofs received from Charlottesville. Va.. has not acrain 

 been reared in this office from the San Jose scale, and the doubt 

 exprest in our original note may 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 e&g parasite only.

The four species just mentioned were recorded in Bulletin No. 3. 

 During the summer of 1^05 three other species have been reared by 

 Messrs. Quaintance and Girault. These are as follow.s: 



Physcus caricornU Howard was reared from ujaterial collected by 

 Mr. Quaintance, ^lay 30. 11^05. at Hampton. Fla. There remains a 

 little doubt as to the parasitism of this species on perniciosm, as 

 according to the note there may possibly have been other hosts present. 

 The known hosts of this species are Asp/dlotus ancyhis Putn., Chion- 

 aspis quercus Comst.. and Chionaspis ammeona Johnson. 



Prospalto aurantu Howard (tig. S) was reared from the ^an Jose 

 scale July 31. VM)h, from material collected from an infested pear tree 

 on the grounds of the Department of Agriculture, at Washington. 

 This parasite atfects 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.
