1 84 INSECT ARTIZANS AND THEIR WORK 



known hy this common name in this country. 

 They are insects that have scarcely to be sought, I 

 for, quitting the fields, they have taken to a life 

 in our homes, laying waste our furniture and 

 clothing. Some of them get beneath the covers

 and scarcely in the right frame of mind to admire 

 it. If she were sufficiently calm to examine it 

 before bringing the back of the brush down upon 

 it, she would find that the occupant is a tiny

 occasion requires ; but it is too economical to do 

 so. The question of increased length is a simple
