Oeder II. Dermaptera* {Earwigs). 



This small group comprises the earwigs, which are noc- 

 turnal insects very rare in this country, except in the 

 Southern States, but common in Europe. 

 Usually placed among the Orthoptera, the ear- 

 wigs have certain important characters which 

 forbid our placing them in that order. The 

 fore wings are very small and short, like the 

 elytra of the rove-beetles, while the large, 

 broad, transparent, hinder wings are folded 

 under the anterior pair, the process of folding 

 being aided by the large forceps at the end of 

 the body; the latter is long and narrow and fig. 43.— Forfi- 

 much flattened. peium C,oce *" 



Family Forficulidae.— Body long, Forficula; body short. Labia.
