tapestries than in the finer and thinner woolen fabrics. It also affects 
felting, furs, and skins, and is a common source of damage to the 
woolen upholstering of carriages, being rather more likely to occur in 
carriage houses and barns than in dwelling houses. Its larva enters 
directly into the material which it infests, constructing burrows or 
galleries, which it lines more or 
less completely with silk. Within 
these galleries it is protected and 
concealed during its larval life, 
and later undergoes its transfor- 
mations without other protection 
than that afforded by the gallery. 
Fic. 3.—Trichophaga tapetzella: Adult moth. En- The damage is due as much or 
pepe eee te more to its burrowing than to the 
actual amount of the material consumed for food. 
One of the parasites, Apanteles carpatus Say, reared from Tinea pel-

REMEDIES. 
There is no easy method of preventing the damage done by clothes 
moths, and to maintain the integrity of woolens or other materials 
which they are likely to attack demands constant vigilance, with fre- 
quent inspection and treatment. In general, they are likely to affect 
injuriously only articles which are put away and left undisturbed for 
some little time. Articles in daily or weekly use, and apartments fre- 
quently aired and swept, or used as living rooms, are not apt to be seri- 
ously affected. Carpets under these conditions are rarely attacked, 
except sometimes around the borders, where the insects are not so 
much disturbed by walking and sweeping. Agitation, such as beat- 
ing, shaking, or brushing, and exposure to air and sunlight, are old 
remedies and still among the best at command. Various repellents, 
such as tobacco, camphor, naphthaline cones or balls, and cedar chips 
or sprigs, have a certain value if the garments are not already stocked 
with eggs or larvee. The odors of these repellents are so disagreeable 
to the parent moths that they are not likely to come to deposit their 
eggs as long as the odor is strong. As the odor weakens the protection 
decreases, and if the eggs or larve are already present, these odors 
have no effect on their development; while if the moths are inclosed 
with the stored material to be protected by these repellents, so that 
they can not escape, they will of necessity deposit their eggs, and the 
destructive work of the larve will be little, if at all, restricted. After 
woolens have been given a vigorous and thorough treatment and 
aired and exposed to sunlight, however, it is of some advantage in 
packing them away to inclose with them any of the repellents men- 
tioned. Cedar chests and wardrobes are of value in proportion to the 
~.
