on p. 119. In the allied pine-gall tortrix ( R. resinella ) the adult has dark 
fore-wings, streaked and mottled with transverse silvery bars and blotches. 
The larva feeds within the stem of the buds of the pine-needles, their ravages 
causing a drop of resin to exude from the twig which grows larger as the 
activities of the internal burrower increase. If the drop of resin be examined 
a small passage at the base will be found passing into the pith of the pine- 
twig, and here the larva may be found. This lump of sticky gum, which attains 
the size of a filbert, and in which the larva passes the pupal-state, has been 
misnamed a gall; but a gall is not an exuding juice or gum—it is a distinct 
outgrowth of the cellular structure of the plant. The woodcut on p. 119 
gives illustrations of the moth, the resin-drop, and the pupa. A figure is also 
given of the ichneumon-ily, which seeks the larva with its long needle-like 
ovipositor; and from its eggs emerge the grubs which will in due course devour 
their nest. An especial interest attaches 
to the pea-moth ( Grapholitha dorsana), 
whose larva is the so - called maggot 
which attacks green peas. When full 
fed it seeks the earth, and constructs a 
cell in which to pass the pupal-stage. 
These larvae also are not averse to a pro- 
vender of dry peas, to which it often causes considerable destruction. The moth 
appears on the wing in May. The well-known codlin-moth (G. pomonella ) takes 
its name from the circumstance that the larva feeds within apple-trees, eating, 
however, not so much the flesh as boring 2 3 
into the heart and feasting upon the pips. 
It is rosy red, paler beneath, with grey 
tubercles, each bearing a long bristle. 
This moth flies in June and conceals 
itself in the daytime in a crevice in the 
bark, with whose tints its grey mottled 
wings readily assimilate. The family of 
the clothes-moths ( Tineidce ) is typically 
represented by the lesser clothes-moth 
{Tinea pellionella), although it must be 
borne in mind that there is not one 
particular moth which destroys clothing, 
but that the larvae of several species are 
equally destructive. T. pellionella is one 
of the smaller of these, whose larvae, of a silky yellow colour, attack all kinds 
of clothing, as well as the upholstery of our furniture. T. tapetzella, a larger 
species, attacks more exclusively furs, skin-rugs, etc. A figure of the larvae of one 
species will be found on p. 121. I 11 the allied corn-moth (T. granella ) the cater¬ 
pillar is very destructive to corn in granaries, feeding indiscriminately upon 
various kinds of grain. The female lays one or two eggs on a single corn-grain; 
and after the deposition of all the eggs, the bodies of the adults may be found in 
numbers in spider-webs in places which they frequent. The presence of the
