Notes on Scale and other Parasitical insects.^ 



By R, Ward. 



^"^JHROUGH the nature of my occupation, scale 

 inse6ls and their ravages come, unfortunately, 

 under my daily observation, and it may be 

 of use and interest to those who possess a garden, if I 

 jot down here a few rough notes on the subject. For 

 the past two or three years some trouble has been taken 

 at the Botanic Gardens, by enlisting the interest of 

 scientific men at home, to get these minute predatory 

 creatures identified. In this matter the Gardens are 

 under obligation to several gentlemen who have made 

 scale insefts a special study, with the result — it can 

 hardly, from the cultivator's point of view, be regarded 

 as a matter of congratulation — of the discovery of several 

 new species. 



A fine set of microscopic slides on which specimens 

 have kindly been mounted by S. J. MclNTlRE, Esq., (to 

 whom we are principally indebted in this matter), has 

 enabled me to identify, and give the scientific names of, 

 the several species of which I shall have to speak. They 

 are not the whole, for several are still being worked out 

 by the scientific experts. My remarks will be chiefly 

 confined to what are technically called Scale Inse6is ; 

 but in addition thereto, I shall add a few observations on 



* Figures of the greater number of Scale Insefts referred to in this 

 paper, will be found in the last volume of Timehri (Timekri, Vol. iii.
