To catch them, place near their haunts several large pill boxes 
containing oatmeal, the lid of the boxes being pierced with several 
holes large enough to allow the insects to crawl in. When caught,

which renders the insects insensible, and therefore easily manipu- 
lated.—/. P. G. 
Tue Fur Moru.—The Fur or Skin Moth ( Zinea pellionella) is 
a little insect with silver-grey wings, marked with one or two spots. 
This moth is worthy the serious attention of dealers in furs and 
skins, because, under certain circumstances, it can cause enormous 
havoc. It lives almost exclusively on the skins, nips the hair off 
close to the roots, and pierces through in countless places, from 
the particles of which it builds a tunnel, serving the insect for its 
habitation.
