woollens and furs should be carefully shaken and examined 

 early in June. Dr. Harris states that "powdered black pep- 

 per strewed under the edge of carpets is said to repel moths. 

 Sheets of paper sprinkled with spirits of turpentine, camphor 

 in coarse powder, leaves of tobacco, or shavings of Russian 

 leather, should be placed among the clothes when they are laid 

 aside for the summer ; and furs and other small articles can be 

 kept by being sewed in bags with bits of camphor wood, red 

 cedar, or of Spanish cedar, while the cloth lining of carriages 

 can be secured forever from the attacks of moths by being 

 washed or sponged on both sides with a solution of the corro- 

 sive sublimate of mercury in alcohol, made just strong enough 

 not to leave a white stain on a black feather." The moths can 

 be most readily killed by pouring benzine among them, though 

 its use must be much restricted from the disagreeable odor 

 which remains, and c 



its inflammable na- 

 ture. The use of a 

 weak solution of car- 

 bolic acid is also rec- 

 ommended. Tinea 

 tapetzella Linn., the 

 Carpet moth, is black- 

 ish at the base of the 

 fore wings, the re- 

 mainder being yellow- 

 ish white, while the b Fig. 204. 

 hind wings are dark gray, and the head white. The larva 

 feeds on carpets, etc. 



Tinea granella Linn. (Fig. 264 natural size, and enlarged, 

 with the wings spread ; a, larva, natural size and enlarged ; 6, 

 pupa, natural size and enlarged ; c, grains of wheat held to- 

 gether with a firm web) the Grain moth, is found flying .in 

 granaries during the summer. The female lays thirty or more 

 minute eggs, one or two on each grain of wheat. The white 

 worm hatches in a few days, eats its way into the grain, clos- 

 ing the entrance with its castings, and after it has devoured 

 the interior of one grain, unites others in succession to it, until 

 it binds together by a fine web a number of them. When
