This fixitude of type in neuration is not one of the least important of the many peculiarities exhibited in these insects.
There is great variety in the shape and neuration of the wings.
Wings not covered by the elytra, longitudinally folded, forming nearly the quadrant of a circle: neuration simple.
The cut shows the neuration, which need not be minutely described.
I have found considerable difficulty and uncertainty in examining the neuration of undenuded specimens.
The neuration is shown in the cut, and is very much like that of the preceding genus.
The neuration of the wing is delineated in the figure herewith given, and needs no further description.
Wings two, with winglets attached to them: neuration various.
Wings longitudinally and transversely folded: neuration simple.
The neuration, considerably enlarged, is accurately delineated in the cut.
