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 whitisli and the head reddish-yellow. The brvn 

 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 tapetzella ; 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. 



Frequent 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° F. 

 is protective.
