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: 
ncuration radiating d . 
Anus forcipate. 
4. OitTHOPTErtA e {Ulonota F.). This Order, which 
Linne at first regarded as belonging to the Coleoptcra ', 
and afterwards improperly added to the suctorious He- 
miptera, was very judiciously separated from both by 
De Geer, under the name of Dermaptcra, a name not
