THE MOTH. 



Thia lesson may be made inteDsely interesting by nsing large 

 moths and bntterflies and comparing them at every step. It U 

 not necessary that all the batterfliea or all the moths should belong 

 to the same species. The common milkweed butterfly, Danais 

 Archippui (Fig. 1), or the large ypUow and black swallow-tail, 

 Papilio Turnus, will be ezcelKnt in comparison with the American 

 silkworm moth, Telea Polyphemus (Fig. 2), or either of the large 

 moths somewhat resembling it. If some of the class have hawk- 

 mothe (Fig. 6), it will be all the better, especially if they can tell 

 from their own observation that these are more rapid fliers than the 

 others, and thus see the use of the longer, more pointed, and more 

 powerful fore wings and the small hind wings working with them. 

 The Polyphemus is here taken first as the basis of the lesson.

 The body of the moth is broader and stronger than 

 that of the butterfly. It has a thicker coating of hair. 

 The wings are larger and not so brightly colored. The
