350 MOTIONS OF INSECTS. 
and affords as much amusement to the entomologist, as 
the latter to the sportsman.—It is to be observed that 
many insects in this order have no wings, and the female 
glow-worms neither wings nor elytra. 
Many persons are not aware that the insects of the 
next order, the Dermaptera, can fly: but earwigs (For- 
Jicula), their size considered, are furnished with very am- 
ple and curious wings, the principal nervures of which 
are so many radi, diverging from a common point near 
the anterior margin. Between these are others which, 
proceeding from the opposite margin, terminate in the 
middle of the wing*. These organs, when at rest, are 
more than once folded both transversely and longitudi- 
nally. 
Wings equally ample, forming the quadrant of a cir- 
cle, and with five or six nervures diverging from their 
base, distinguish the strepsipterous tribe. When unem- 
ployed these are folded longitudinally. 
Probably in the next order (Orthoptera), the Tegmina, 
or wing-covers—since they are usually of a much thin- 
ner substance than elytra—assist them in flying. They 
are however quite covered by irregular reticulations, 
produced by various nervures sent forth by the longitudi- 
nal ones, and running in all directions. When at rest, 
the inner part of one laps over that of the other‘: but in 
different genera there is a singular variation in this cir- 
cumstance. ‘Thus in Blatta, Phasma, and male Locusta,

ascertained that the spurious elytra of these insects are serviceable 
in their flight. As M, Latreille now allows this, he ought to have 
restored its original name, which he had altered, to this order.
