The Boxnbycidfe, or silk-spinning moths, furnish us with some very large and beautiful 

 species, the most striking, indeed, of all our insects, whether in the caterpillar or perfect 

 state.

Samia cecropia, L., is known by all fruit growers as a depredator upon apple, plum, 

 and other trees. The caterpillar (figure 19) is, when full grown, fully three inches long, 

 and its bright colours and curious spined tubercles render it a very striking and inter- 

 esting object. The moth, like those of the three following species, has been frequently 

 figured in our reports. 



Teleas polyp)hemus, L., the larva of which' is 

 shown in Figure 20, is a somewhat smaller and more 

 modestly colored moth, and the caterpillar has not 

 such a formidable appearance. It is, when fully 

 grown, about three inches long, and correspondingly 

 stout, of an apple green color, and ornamented with 

 bright colored tubercles and short lines. It feeds on 

 a great variety of trees.
