Classification of Insects: LcphJoptera. 



(Male.) 



102. Bombyx neustrin. 



(Female.} 

 (Perfect Insect.) 



The first of these has, by later naturalists, been merged with others, 

 but, with this exception, these groups have been considered as well 

 marked, and are generally retained. We present a few examples 

 of some of these forms. 



695. The Bomby- 

 ces, or spinners, are 

 thick-bodied moths, 

 Avith feathered an- 

 tennas, at least in the 

 males, tongue short 

 or wanting, thorax 

 woolly but not crest- 

 ed, and the larva? 

 generally spinners. 

 The figures here giv- 

 en show one of nu- 

 merous species of 

 this group. They 

 have sometimes 

 proved exceedingly 

 destructive, by eat- 

 ing off the leaves of 

 trees, while in the 

 larva state. We 

 here present a view 

 of the perfect insect, 

 the Iarva3 of which 

 prove very destruc- 

 tive to the Scotch 

 pine. Whole forests 



103. Larva of the Bombyx neustria. 



104. Bombyx of the Pine. (Female.)
