It can accommodate 566 persons and includes a semicircular orchestra divided into three radial sectors.
2.
The radial sector may fork twice.
3.
The radial sector Rs has one or two forks . Additional crossveins are sometimes present in cells r3 an1 and m.
4.
The original purpose of the Mojette Transform was to create a discrete tool to divide the Fourier plane into angular and radial sectors.
5.
The wing venation, although variable within the family, has some common characteristics that can be summarized basically in the particular morphology of the branches of the radial sector and the reduction of the forking of the media.
6.
Toward the middle of the wing, it forks into a first undivided branch ( R1 ) and a second branch, called the radial sector ( Ra ), which subdivides dichotomously into four distal branches ( R2, R3, R4, R5 ).
7.
These insects differ from the somewhat similar Chrysopidae ( green lacewings ) not only by the usual coloring but also by the wing venation : hemerobiids differ from chrysopids in having numerous long veins ( two or more radial sectors ) and forked mimic dead leaves.
8.
Sc2 fuses with radial vein R slightly distal to the base of the radial sector vein Rs an this is not longer than mcu . m1 is sessile, only rarely short and petiolate . mcu is located before the base of the discal cell ( d ).
9.
Corydalinae is distinguished from closely related clades by the following synapomorphies ( with exceptions in a few species ) : quadrate head with a postocular spine, ridge, and plane, non-pectinate antennae, four crossveins between the radius and the radial sector, and distinctive male terminalia with a well developed ninth gonostylus.
10.
The costa is spread over the entire margin and the subcosta is long, often ending on the distal half of the costal margin . The radius is almost always divided into four branches, with fusion of the branches R 2 and R 3, and is characterized by the sinuosity of the end portions of the branches of the radial sector.
