in its characteristic groove, but its abdominal characters differ 

 very clearly. 



Aspidiotus perniciosus, Comstock ; and a variety. Rep. 

 Entom. U.S. Dept. Agric, 1880, p. 30i. 



This insect occurs in Australia on apples and pears. I 

 have received specimens from Melbourne sent by Mr. French, 

 and from New South Wales sent by Mr. Benson. It was 

 reported in that countrv first by Mr. OUiff, in the Agricultural 

 Gazette of New South Wales, 1892, p. 698. 



In a paper forwarded to the Entomologists' Monthly Maga- 

 zine I have discussed the relationships or differences between 

 this species and Aonidia fusca, Mask., 1894. 



In August, 1895, I received from Mr. Quinn, of Adelaide, 

 some twigs of Eucalyptus corynocalyx thickly covered with 

 insects which, after careful examination, I must attach to 

 A. -perniciosus. The puparia in this instance are very dark 

 grey, and the larval pellicle is orange-red. The second pellicle 

 is not visible until the scale is turned over, and then only in- 

 distinctly. But the characters of the adult female are quite 

 clearly those of A. perniciosus, and in this case I have also the 

 advantage of finding some adult males, which are identical 

 with the figure of A. perniciosus given in " Insect Life," 

 vol. vi., p. 369. Mr. Qninn says nothing about the presence 

 of the insects on any European fruit-trees ; but as to the 

 Eucalyptus he remarks, "seems to destroy the bottom 

 branches of young trees where it has been for a year or 

 two." 



It appears to me clear that A. pierniciosus may vary a good 

 deal in the colours of its puparia and of their pellicles. I 

 have therefore placed this insect in my cabinet with the 

 label "A. perniciosus var." ; but I will not add the word 

 "eucalypti," as I have no reason to think that it is peculiar 

 to that family of trees.

I have received specimens of this insect from Adelaide, 

 South Australia, on Lauriistinus. They were sent by Mr. 

 Q-uinn, who says, " fairly common on that plant, though its 

 injurious effects are not very apparent."

This insect has been sent to me by Mr. Lea, on lemons 

 from Perth, Western Australia ; the fruit was imported there
