| There is great variety in the shape and neuration of the wings. |
| I have found considerable difficulty and uncertainty in examining the neuration of undenuded specimens. |
| In this Order it is curious to trace the progress of neuration in the wings of different genera. |
| The cut shows the neuration, which need not be minutely described. |
| The neuration, considerably enlarged, is accurately delineated in the cut. |
| This fixitude of type in neuration is not one of the least important of the many peculiarities exhibited in these insects. |
