doubtedly the insect described by Dr. Targioni-Tozzetti under the name 

 of D. longispmus, but Dr. Siguoret treated this name as a synonym of 

 D. adonidum, Linn., and I note that Prof. Cockerell, in his " Check- 

 List of Coccidce,'^ follows Signoret in this determination. There is, 

 however, considerable doubt about the identity of Linne's species. The 

 name adonidum has been frequently applied to the very common and 

 widely distributed species now generally recognised as D. citri. It 

 would seem advisable, therefore, to retain the name of longispinus, 

 which has been in use for many years, to designate the species with 

 very long waxy processes, of which the terminal pair are frequently 

 longer than the body of the insect itself ; c/^ri being recognised by 

 its stouter form, and the very short marginal processes. Dr. Antonio 

 Berlese has pointed out many small structural differences between 

 the two species. 



Oethezia insignis, Doug. — This species seems especially partial 

 to plants belonging to the natural Order Acanthacece. The same fact 

 was noticeable in Ceylon, where the insect became a serious pest upon 

 ornamental plants in the Government Botanical Gardens at Peradeniya. 

 It was particularly noticeable at Kew upon Sfrobilanthes gossipinus 

 (an Indian plant), also upon Manettia hicolor (from Tropical America). 

 I was told by the attendants that this insect was known amongst them 

 by the name of "the Kew bug," and that constant attention was 

 required to prevent its increase.

ADDENDA BY K. NEWSTEAD. 



In order to prevent the repetition of names, and to economize 

 space, I have ventured to give, in the form of bracketted notes, a few 

 remarks on the species enumerated in Mr. Green's interesting paper. 

 I have now to add, as the result of my pleasant and profitable visit to 

 the Royal Gardens, the following species as additional to the fore- 

 going list : — 



AspiDioTus CTDONi^, Comstock ; (J and ? scales. — Numerous on 

 the dead wood projecting from the trunk of the large sugar palm 

 {Arenga saccharifera, from the Malay Archipelago) ; but, judging 

 from the appearance of the scales, the insects had long since been 

 dead. They were badly parasitized, and attacked by fungi, which, 

 together with the use of insecticides, had apparently destroyed the 

 whole colonv.
