SYSTEM OF INSECTS. 379 



Wings not covered by the elytra, longitudinally 

 folded, forming nearly the quadrant of a 

 circle a : neuration simple. 

 Anus styliferous b . 



3. DERMAPTERA c ( Ulonota F. Orthoptera Oliv.). This 

 is another osculant Order, evidently connecting the Co- 

 leoptera with the Orthoptera. The elytra are of a cori- 

 aceous substance, have a straight suture, and are not 

 veined, and the wings are folded longitudinally as well as 

 transversely, circumstances which connect it with the 

 former Order, while the shape of its wings, its oral or- 

 gans, and its metamorphosis, show its affinity to the latter. 

 It was established at the same time and in the same 

 work with the preceding Order, in pursuance of a sug- 

 gestion of Dr. Leach, and consists solely of the Linnean 

 genus Forficula. 



DEF. Metamorphosis semicomplete. 



Elytra coriaceous, without veins, united by a 



straight suture, so as partly to cover the wings. 

 Wings longitudinally and transversely folded, 



each forming nearly the quadrant of a circle: 



neuration radiating d . 

 Anus forcipate. 



4. ORTHOPTERA e (Ulonota F.). This Order, which 

 Linne at first regarded as belonging to the Coleoptera f , 

 and afterwards improperly added to the suctorious He- 

 miptera, was very judiciously separated from both by 

 De Geer, under the name of Dermaptera, a name not
