ORDER II. — EUPLEXOPTERA. 



This order, which is the Dermaptera of Leach and Latreille, 

 but not of Retzius, comprises the family of the earwigs, and 

 is distingmshed by having the body of an elongated form, 

 and terminated by a scaly forceps formed of two long and 

 curved horny appendages, pointed at the tip, and having 

 several small teeth on the inner margin ; the tarsi are three- 

 jointed. The wing-covers are short and square, not covering 

 more than one-third of the abdomen ; the wings are of large 

 size, although but seldom seen, being shut up by means of 

 numerous longitudinal and transverse folds, so as to occupy 

 but a very small space. This insect has so much the appear- 

 ance of some of the StaphylinidcB, that Linnaeus was induced 

 to place it in the order Coleoptera, with which it indeed 

 agrees, in having the wing-covers united (when closed) in a 

 straight line ; the transformations, however, which it under- 

 goes do not agree with those of the beetles, the insect re- 

 taining its powers of locomotion, and, consequently, of feed- 

 ing, during the pupa state ; in which respect, as well as in
