DERMAPTERA. 101 



The ear-wigs are terrestrial, very generalized in 

 structure, and placed by Brauer and Packard next to 

 the Thysanura ; but their close relations to the Orthop- 

 tera have been recognized by these authors, and we 

 have placed them next to, though not in, that order, 

 as has been done by several of the best authorities. 

 Their larval and adult characters seem to indicate the 

 primitive origin of the two groups Dermaptera and 

 Orthoptera.
