Anterior wings with two submarginal cells and one recurrent nervure.
2
Each space is surrounded by a strong nervure and goffered by slight wrinkles or depressions.
3
NEURATION.-Thearrangement of the veins or nervures in the wings of insects.
4
The crickets stridulate by rubbing together the strong nervures of the fore wings.
5
The anterior wings with two submarginal cells and two recurrent nervures.
6
I see other nervures in the intervals, pale and very fine.
7
Numerous nervures, spreading out fan-wise, cross them in the direction of their length.
8
I see a bundle of moderately strong nervures radiating fan-wise.
9
Finally, still more delicate, and running transversely, a number of very short nervures complete the pattern.
10
It will be found that the two bows-thatis, the toothed or indented nervures-crossone another obliquely.
11
One by one the branching nervures hardened.
12
The instrument by which it produces its music is contrived out of the ordinary nervures of the wing-case.
13
This lateral fold encloses the flank of the abdomen and is covered with fine oblique and parallel nervures.
14
I can plainly recognise the longitudinal nervures, which are already stiff; and I can also see-pale, and without relief-thetransverse nervures.
15
It is, as before, a dry white scale, convex on the outside, and crossed by a bundle of fine reddish-brown nervures.
16
In the dragon-flies, the nervures are minutely netted for the sake of increased strength; in the bees, the nervures are simply parallel.
