This list is not added to in the "Report of the Commission," &c., 

 published at Cape Colony in 1877. Mr. Trimen, in the article cited 

 above, gave the preference to the trees and shrubs of Australian origin; 

 but Mr. J. C. Brown {loc. cit.) quotes him as writing, under date of 

 March 17 (1882?), that the insect had then mainly attached itself to the 

 orange trees. "Many of the finest plantations have been destroyed 

 and others are on the high road to destruction. You will remem- 

 ber," he says, "how good and cheap oranges used to be here; they have 

 lately been three pence and four pence apiece, and often inferior in 

 quality even at such a price." 



Its Food-plaxts in New Zealand. — From the various communi- 

 cations of Mr. Maskell and others in the Transactions and Proceed- 

 ings of the New Zealand Institute we give the following list of plants 

 which have been especially designated. There has been no attempt, 

 however, on Mr. Maskell's part to give at all a complete list, and in 

 fact, he says,* "In Auckland it is attacking all sorts of plants, from 

 Apple and Rose trees to Pines, Cypress, and Gorse": 



Common Furze. 



Orange. 



Lemon. 



Acacia decurrens. 



Acacia armata. 



Apple. 



Wattles. 



Rose. 



Gorse. 



Pine. 



Cypress. 



Its Food-plants in California. — Originally starting upon ^c«cia 

 latifolia at Menlo Park, this insect soon spread to numberless other 

 plants. Dr. Saxe, in 1877, mentioned that it already attacked the 

 Acacias, Australian Pea-vine, Rose, Honey-suckle, Ivy-geranium, 

 Laburnum, Pear, and the weeds in the orchard.
