ISTo insects seem to feed upon the fig in the open in this country, 

 but under glass it is frequently attacked by Eed Spider and Thrips. 

 More rarely we find Mealy Bugs and the Scale insects dealt with 

 here. 



THE SOFT BROWN SCALE. 



(Lecanium licqicridum. Linnseus.) 



This species I have found twice on figs in this country. It is 

 common under glass, and attacks a great number of plants, and also 

 occurs out of doors on ivy, myrtle, holly and bay. 



The female when full grown is about ^ inch long; the colour 

 varies from yellow, when j'oung, to brown when adult. The young 

 female is flattish, and has often brown markings on the yellow 

 ground, forming an irregular network, which coalesces as the insect 

 grows. After death the insect becomes pale brown. In form, it is 

 convex, and there is a trace of a central ridge ; after death the edges 

 become crinkled. The female is viviparous. The male is very un- 

 common. The puparium of the male is said by Newstead to be 

 glossy. 



This species may easily be told by the quantity of honeydew it 

 secretes, and the consequent growth of black smut fungus around it.
