and to satisfy myself that saccliari was really distinct from i)urchasi. 

 This fact, while not absolutely opposed to the idea of the origin of the 

 Fluted Scale from the islands of Bourbon and Mauritius, because both 

 species may occur there, tends, nevertheless, to confirm the prevailing' 

 opinion, and that which I originally held, viz, that the native home of 

 the species is in Australia. 



A limited number of natural enemies and parasites have already been 

 discovered upon it in California. They are as follows:

I^nTow, as the number of these enemies (and particularly of the para- 

 sites) increases, the fruit-growers of California will get more and more 

 relief from the ravages of the Icerya ; but it is an interesting fact that 

 in Australia, which, as we have seen, is in all probability its native 

 country, the species is not so injurious as it is with us, the reason being, 

 doubtless, that it has natural enemies there which serve to keep it in 

 check, and which have not been transported with it to the countries of 

 its introduction. Here we have a case where it would be eminently fit 

 to have these enemies in Australia especially studied and to attempt to 

 introduce them to California ; for the successful accomplishment of this 

 would, without doubt, result in immense benefit to the people of that 

 State. With most of the paiasites this would be an easy matter from 

 the very manner in which they are known to affect the Icerya. In fact, 

 since I delivered an address upon this subject, last spring, at Kiverside, 

 Cal., the people of that State have been alive to the imi)ortance of the 

 subject, and have in county and State conventions appenled by resolu- 

 tion to Congress to authorize the sending of a commission to Australia 

 for this purpose. 



This is nature's method of checking the evil, and one which it were 

 wise for man to adopt. At the present time it is possible for the fruit- 

 growers of California to protect their fruit trees by vigilant mcinis and 

 rather large expenditure of time and money, and where these are not 

 employed ruin stares the orange- grower in the face. The introduction 

 of the natural enemies which kee^) the species in ciicck in its native 

 country would soon bring about a change in this country, and its intro-
