nearly to the base, and resembling distinct 



plumes. 



Some moths fly by day ; but they may be 

 said, generally, to avoid the light, and leave 

 their lurking-places only in the evening. The 

 caterpillars vary greatly in size and shape. 

 Among the most singular is that of the Pha- 

 lana Vinula y or Poplar Moth. It is more than 

 two inches long, with a flat face, and pointed 

 shoulder ; but the tail is the most remarkable 

 feature, being extended into two long tubular 

 processes, which can be further lengthened at 

 the pleasure of the animal. 



Of the chrysalids of moths, some are quite 

 simple, while others are provided with a hook 

 at one end. All of them weave a covering, 

 which, in such as pass their time under ground, 

 is of very coarse materials. Many of the spe- 

 cies attach themselves to the under sides of 

 branches of trees, to walls, or any convenient 

 substance chosen by the insect for that purpose. 

 Of these the web is much finer, and generally 

 contains more silk.
