334 INSECTS 



Adelaide, Melbourne and Sydney, on almost every kind of plant; but 

 the first announcement of its appearance in New Zealand was in 1895, 

 when Captain Broun found it on olive trees at Whangarei. Later the 

 Agricultural Department reported it as occurring on various species 

 of Citrus, and on Camellia. The species, which is cosmopolitan in 

 its distribution, is now common and very troublesome in the northern 

 parts of New Zealand. 



Coccus maculatus, Signoret (Lecanium maculatum} 



This European species was reported by Mr Maskell in 1878, as 

 occurring on Bouvardia in a greenhouse in Christchurch. I do not 

 know that it has been recorded since. 



Coccus mori, Signoret (Lecanium mori) 



Taken by Mr Maskell onAlsophila and other plants in the Botanical 

 Gardens, Wellington, in 1884; and in 1893 on Asplenium and other 

 ferns. In 1895 it was found to be plentiful on gorse (Ulex europceus) 

 and broom (Spartium or Genista) at Fairlie in South Canterbury. 

 (The latter is probably Cytisus scoparius.) 



Coccus longulus, Douglas (Lecanium longulum, Douglas ; 

 L. chirimolice, Maskell) 



In 1889 Mr Maskell recorded this species from Fiji, where it 

 was found on the bark and leaves of the Peruvian Cherimoyer (Anona 

 tripetala). In 1896 he states: 



This insect has come to New Zealand. Captain Broun sent me specimens 

 on Laurus, from Northcote, near Auckland. It has evidently been imported 

 from Fiji, between which place and New Zealand there is a rapidly-growing 

 trade in fruit, etc. 



Coccus hesperidus, Linn. (Lecanium hesperidum, Blanch). 

 Broad Scale ; Holly Scale ; Ivy Scale 



In 1878 Mr Maskell wrote: "This insect is becoming a veritable 

 pest in this country. Hollies, ivies, Portugal laurels, and many other 

 trees in our gardens are every year becoming more and more infested 

 with it." In 1887 he added Camellia, orange, myrtle, box, etc., and 

 stated : " this is the commonest of the Lecanidae in this country." It 

 is also found on oranges, gooseberries, and occasionally on grape- 

 vines. 



In 1888-89 Dr Jas. Hudson recorded this species (under the name 

 of Lecanium hispidum) as occurring on orange and lemon trees in 

 Nelson, and badly infesting the trees. In February, 1890, he observed 

 Rhizobius ventralis preying on the Coccid; and in January, 1891, he
