CLASS HEXAPODA.

ORDER DERMATOPTERA (der ma t6p'tS ra). 



The Earwigs have a much higher or- 

 ganism than that which is possessed by 

 the Spring-tails, though terminal filaments 

 (fil'a ments) are retained, these forming a 

 pincer-like organ. The posterior wings 

 are, during the day, folded beneath the 

 hardened anterior wings, the so-called ely- 

 tra (en tra).

ORDER PSEUDONEUROPTERA (su do nu r6p'te ra). 



FIG. 103. 



The members, of this 

 order have an incom- 

 plete metamorphosis, 

 the active pupa stage 

 differing from the larva 

 in the possession of 

 "wing-pads."* The 

 lower lip is generally 

 deeply cleft, and the- 

 wings, when present, 

 are four in number, re- 

 ticulate (re tik'u lat) and 

 membranous. 



The White Ants 

 (Termes), though abounding in the 

 warmer regions, are represented in our 

 country by only a few forms. Differing 

 in many important structural details 

 from the true Ants, they resemble these 

 in their habits, living in large organized 



* Rudimentary wings.
