furnished by the common Yponomeuta cognatellus. This species, "whose 
natural foodplant in this country is the Euonymas europaeus, seems to 
have taken most kindly to the Euonymus japonicus, -which is so 
abundantly planted in the suburbs. Depressaria cnstosa, which feeds 
on broom and furze, will also flourish on at least one ornamental 
Cytisus, which is, I believe, of south European origin. In the woods, 
the blackthorn furnishes the foodplant to Nepticula plagicolella, but in 
Chiswick its mines may be found in the leaves of the Victoria plum, 
which is so much grown in the market gardens. 
A second set of survivors is formed by those species which are 
more or less polyphagous, and therefore when one foodplant fails they 
readily accustom themselves to another. Thus Coleopliora paripennclla 
will eat bramble, blackthorn, and rose. Carcina quercana is, however, 
a better example. I have found the larva in Chiswick on almost 
every kind of tree. It seems to have taken a special fancy to Arbutus 
and Laurestinus, owing probably to these plants being evergreen, for 
this species is in the larval state throughout autumn and winter. It 
may be worthy of remark that among the Tineina there is a much 
smaller proportion of general feeders than among the Tortrices or 
Macro-lepidoptera. 
A third class of species that will probably continue consists of those 
moths whose larvae feed on plants commonly cultivated in gardens, or 
on shade plants grown in the streets. Gelechia rnalvella, for instance, 
feeds on the seeds of the hollyhock, Nepticula anomalella mines in the 
leaves of roses, and Gracilaria syringella feeds on the lilac. The last 
often makes the lilac bushes quite unsightly by the numerous large 
brown blotches which its depredations cause in the leaves. The 
beautiful red and black Chrysoclista linneella feeds in the bark of lime 
trees, and may be found in July on the trunks, even in the metropolis. 
Of course, Gelechia rnalvella and Gracilaria syringella have accustomed 
themselves to these cultivated foodplants, but they have now become 
so attached to them, and their original fooodplants have become scarce 
in the suburbs, so that hollyhock and lilac have now become their 
natural foodplants. 
A fourth group, not likely to die out, is composed of those species 
which are not dependent on growing vegetation for their sustenance. 
The clothes moths are familiar examples of this group. 
Several species of the genus Tinea and others feed on fur, feathers, 
hair, and other non-vegetable substances, but it appears doubtful 
whether these species always consumed such food. It seems probable 
that the earliest haunts of this group were decaying trees and fungoid 
growths, and that the larvae wandered by chance into a deserted bird’s 
nest, and thus acquired a taste for their present food. It is possible 
that they shared the cave dwellings with Paleolithic man, and they 
were doubtless inhabitants of the huts of the ancient British. Some 
species of this group appear to have spread with commerce, and 
several are now less abundant in the country than in the towns, AAhere 
they can often obtain more congenial surroundings. The clothes 
moth par excellence is undoubtedly Tineola biselliella. This is a small 
pale ochreous moth with a rough-haired bright ochreous head. It is 
well named, as it will make its home in the most palatial residences 
among the finest curtains and carpets that art can produce and money 
procure, but it will flourish apparently quite as happily in the smallest
