salmon, and the lobster, are not without their 

 company; while every hot-house, and every gar- 

 den is infested with some peculiarly destructive. 



THE LEAF LOUSE. 



THIS animal is of the size of a flea, and of a 

 bright green, or bluish green colour ; the body is 

 nearly oval, and is largest and most convex on 

 the hinder part; the breast is very small, and the 

 head is blunt and green; the eyes may be seen 

 very plainly, being prominent on the fore-part of 

 the head, and of a shining black colour; near 

 these there is a black line on each side; and the 

 legs are very slender. Like many other insects, 

 they cast their skins four several times; and, 

 what is very remarkable, the males have four 

 wings, but the females never have any. They 

 all have long legs, not only to enable them to 

 creep over the long hairs of plants and leaves, 

 but also to travel from one tree to another, when 

 they happen to stand at a distance. Their trunk, 

 or snout, lies under their breast; and this they 

 thrust into the pores of the plant to suck out the 

 juice, for they do not gnaw them, like the cater- 

 pillar; but so hurt them by sucking, that the 

 leaves become spotted, and as it were over-run 

 with scabs: for which reason their edges always 

 nrn towards the middle.
