tubes firmly to the surface with silk. The pupal stage takes place 
inside the case and lasts from two to three weeks. 
2. The Webbing Clothes Moth, the Tincola biselliella of Hummel, 
is about the same size as the preceding species, and has the front 
wings pale ochreous, and more or less shining, without any spots ; the 
hind wings are whitish and the head reddish-yellow. The larva 
feeds on a great variety of substances, such as woollen goods, furs, 
feathers, the linings of chairs and sofas, and has been found feeding 
on cobwebs. The moth appears from March to October and produces 
two broods in the year. The larva is dirty white, and spins a silken 
webbing as it progresses over its food material ; no true case is 
formed as in the preceding species ; but when mature it spins a 
cocoon of pieces of hair or wool of irregular outline and pupates 
within it. 
3. The Tapestry moth, the Tinea tapetzella of Linnaeus, is also 
known as Trichophaga tajpctzclla ; its fore wings are black from the 
base to the middle, then white clouded with grey towards the tip, the 
hind wings are pale grey and the head is white ; the wing expanse is 
about three-fourths of an inch. It appears during June and July. 
The larva forms galleries in the cloth or other substance it attacks, 
these galleries being lined with silk. It affects carpets, horse cloths, 
upholsterings, especially in carriages, also furs and skins. The pupal 
stage takes place inside the galleries. Heavy and coarse materials 
are attacked mainly by this species, which damages by its actual 
burrowing into the material upon which it feeds. 
Treatment for Clothes Moths. 
Frecpient removal, beating and shaking of clothes, etc., will do 
much to prevent the harm caused by these three pests. Materials 
which are liable to be attacked should be put away in boxes and 
cupboards with pieces of naphthalene in muslin bags placed here and 
there. Exposure to sunlight and plenty of air in May and June will 
do much to prevent clothes being spoiled by them. Benzine has a 
very deleterious effect on these pests and any valuable materials 
might be treated now and then with this substance. 
In the case of cloth-covered furniture spraying with benzine is 
the most successful way of treatment. 
Large dealers of carpets and furs could always keep their stock 
free from attack by adopting cold storage. A temperature of 40° E. 
is protective.
