 ICERYA PURCHASI, Mask. (Fig. 27.) 



Icerya purchasi, Maskell, Trans. Proc. N. Zealand Inst. 

 xi. p. 221, t. 8, f. 20, 21. 



PIG. 27. Icerya Purchasi (female), much magnified; group, magnified 

 S. African ; group on twig and leaf, rather less than life-size 

 N. American (after fig. by Mrs. Comstock). 



The first edition of this paper was published in 1887, 

 as a separate pamphlet, under the title of the ' Australian 

 Bug of South Africa,' but this has now been entirely 

 issued, save one or two copies in the hands of the writer. 

 Therefore I reprint it now in somewhat abridged form, 

 excepting ivith regard to the applications which have been 

 found of use in destroying the pest. These are repeated, 

 as the serviceableness of soft soap application, as one of tit e 

 best insecticides in this case, has since been confirmed, botli 

 in S. Africa and by a vast series of experiments in the 

 United States of America.
