SOME INSECT WINGS
H. E. Jacques, How to Know the Insects, 2nd ed., Wm. C.
In several orders of insects wing structures play an important

The usual abbreviations have been employed in designating the veins as
follows:—C, Costa; Sc, Subcosta; R, Radius; M, Medius; Cu, Cubitus; A, Anal.
(One of the coolest sites, evar!)
