of the peach-tree. When just born its colour is white, with a pale green tint on the 

 hind part of the body, the eyes only are dark. The body is then linear and flat, but 

 as the insect grows it changes more and more in colour and shape, till it arrives at its 

 full size, when the body is short, oval, convex, shining, dark green, the sides of the ab- 

 domen pale; horns of the abdomen very short : the antennse are slender, setaceous, 

 dark, with a band beyond the middle of each, shorter than the body; the legs are white, 

 the tips of the thighs and of the tibiae, and the whole of the tarsi are dark green. When 

 winged it is black, having the abdomen dark green, the antennae and legs black banded 

 with dark green, and the wing-nervures green. — Id. 



49. Aphis of the Currant. Found during May on the underside of currant-leaves 

 in profusion, and in all stages of growth. The colour is pale green, only the eyes dark, 

 the young ones are almost white, but as they increase in size, the green colour becomes 

 more and more vivid. The winged insect is comparatively rare at this time; it has the 

 disk of the head, of the thorax and of the abdomen black, the antennae black, the legs 

 banded with black, there is a row of black spots on each side of the abdomen, and the 

 nervures of the wings are black. — Id. 



50. The Aphis of the Cherry has a more dilated body than most species of Aphis. 

 It swarms on the young shoots of the cherry in May and June, and is infested by an 

 Allotria, which mounts on the back of its victim and lays eggs within the skin. — Id. 



51. Aphis of the Turnip. Two distinct species of Aphis infest this jilant; the one 

 is bright pale red in colour, the other green, covered with white down, is also abun- 

 dant on the cabbage. — Id. 



62. The Aphis of the Sotv-thistle attains its full size at the beginning of June, 

 when its colour is quite white, like that of the roots of the plant. The same species, 

 or one nearly allied, is common on the roots of grass in July. Its antennfe are short 

 and filiform, but another kind of Aphis that dwells, in June and July, beneath the 

 leaves of the sow-thistle, has setaceous antennae. The latter species is infested by a 

 minute Acarus of a bright orange colour. — Id. 



53. Aphis of the Oak. This species inhabits the underside of oak leaves in May 

 and June. The colour of the young is whitish green ; but afterwards they acquire 

 two bright green stripes along the back, and when they attain their full size, the co- 

 lour becomes pale red, the upper side of the body having a dark red stripe along it. 

 The legs and antennae are short, and the latter also filiform ; the abdomen has two tu- 

 bercles near its tip. — Id. 



54. The Aphis of the Bean appears on that plant in the beginning of July. — Id. 



55. Aphis of the Sycamore. There are two species ; the one appears early in the 

 spring, the other, which also infests some other trees, is more abundant in the sum- 

 mer. The latter has a black body, the legs and antennae are green banded with black, 

 the wings limpid, with green nervures. When young, the body is altogether bright 

 green. — Id. 



56. Aphis of the Apple-tree. Common under the leaves of that tree during spring. 

 It has setaceous antennae, and is very different from Eriosoma Mali, which infests the 

 wood. — Id. 



57. Lachnus. Two species of this genus live on the shoots of the spruce fir, and 

 two more on those of the Scotch fir. — Id. 



58. Orgyia antiqua. The beginning of May is the most favorable time to take the 

 larvffi of this moth. I have found them in Coombe Wood, feeding on the bramble, 

 though I believe the hazel is their favourite food. These larvae, like those of Lasi-
