Insect Pests. 



lu this insect no true scale is fornieil, \vli;it is called the scale 

 is merely tlie hardened skin of the female. 



It will lireed iu this country very rapidly under glass, and it is 

 important to kill it directly it is seen on the wood of the fig, before it 

 gets on to the leaves. 



THE CAMELLIA SCALE. 



."^ignoret. ) 



(Aspijl lol iix I'liiiiill III', 



This limpet-shaped scale is often very common on cultivated figs, 

 and unless kept in hand will spread on them to a dangerous extent. 



Tlie female scale is either oljlong or 

 broadly pyriform, its colour varies from 

 reddish-brown to dusky lirown, with the 

 so-called exu\'ium at tiie apex, paler in 

 cohiur ; there is a distinct pure wliite 

 lower scale. The latter remains on the 

 plant wlieu the insect is removed ; the 

 female is oiange-yellow and the scale 

 reaches alidut ^'^, inch in diameter. The 

 male is unkmiwu. 



It occurs ou many other plants, 

 such as tlie camellia, eupihorliia. be- 

 gonias, myrtles, asparagus fern, luit 

 only under glass in this conntrv. 



It increases with great rapiditj', there 

 being a succession of broods, reproduc- 

 tion always being parthenogenetic. 



THE NARROW FIG SCALE.

'I'his (_'occid is sometimes found nu 

 tigs under glass. Jilorgan (1) refers to 

 it as ha\'iug Vieeu found in abundance

 Society'.'^ (Tardens at I'hiswiclc. Tdie 

 l)lants had been imported frcim France 

 fifteen years pi'c\inusly. 



The scale much resembles that of 

 our Apple ilussel Scale, but that of the 

 I'emale is more elongate, Imv mirrower.
