moths away. They will not drive away the larvae after they are 

 hatched. 



The Webbing Clothes-Moth. This is a second species of 

 clothes moth (Tineola biselliella Hummel), which is distinguished 

 from the preceding insect by the absence of the larval case. A 

 silken web, however, is spun from the material wherever the larvae 

 are working. The species generally has two broods. The second 

 brood of larvae work in the latter part of the hot weather. When 

 the larva is full grown it makes a cocoon of silk or woollen particles 

 and changes to a pupa within. 



The measures of control are the same as for the preceding 

 species. Figure 299 illustrates the larva and its moth. Figure 300 

 is a clothes-moth larva as seen under a microscope.

Riley.) 



The Carpet Beetle, Buffalo Bug, or "Buffalo Moth." This is 

 a small beetle (Anthrenus serophularice Linn.), not over a quarter 

 of an inch in length, blackish, with red and white markings. It 

 normally passes the winter under the bark of trees. It finds its way 

 into the house in the spring and deposits its eggs in the carpets or 

 on clothing. Two or three broods occur in a single season. The 

 young grubs are hairy creatures and rejoice in the fanciful name 

 of " buffalo bug" (Fig. 301). 



Injury. In the larval stage injury is caused by their feeding 

 on carpets, clothing, or upholstered articles. 



Control. Once established, this pest is difficult to remove. 

 Infested carpets should be taken up and steamed, the floors cleaned, 

 and the cracks treated with gasoline. If the carpets cannot be 

 removed, use gasoline on the infested parts. The usual precau-
