Plates IV. to IX. 

 Since the pubhcation of my book on the scale-insects of 

 New Zealand a iew new species of this family have been 

 brought under my notice, chiefly from localities which I have 

 )iot been able to visit, and from trees on which I could make 

 no personal observations. In addition, some insects have been 

 sent to me for identification from New South Wales and from 

 Fiji, and I have included them in the present paper. 



I have to tender my thanks to Mr. G. Bennett, of Sydney ; 

 to Mr. E. L. Holmes, of Bua, Fiji ; and to Messrs. E. Eaithby 

 and T. Cavell, of Inangahua, New Zealand, who have very 

 kindly sent me numerous specimens from their respective 

 localities. Mr. Holmes has sent me a fine collection of 

 Coccids, Aleurodids, and Apliids ; and the two last-named 

 gentlemen have been specially assiduous, and have spared no 

 trouble in their assistance to me.
