ches from Rs are bent in such a manner that an appa- 
rently continuous or nearly continuous, straight line is for- 
med, running through the middle of the apical third of 
the wing; this line is named the anterior Banksian line*). 
In the forewing M is forked about one third from its base; | 
its upper branch, Mz, or only M, continues in an almost 
straight direction of the median stem towards the margin 
of the wing; its lower branch has the shape and the di- 
rection like an oblique crossvein, and it disappears ap- 
parently when it reaches Cuz. In the hindwing M forks 
close to the base of the wing. Mz7 runs like an unforked 
nervure towards the margin of the wing; the anterior 
branch, M 2a, has almost the same direction as Mz; the 
posterior branch, M 27, runs as arule in an oblique direc- 
tion into the hind margin of the wing. M2a emits a series 
of branches towards the hind margin, and the branches 
have almost the same direction as M2p. In several of the 
broad-winged forms the branches from M 2a together with 
a longitudinal series of crossveins form a more or less 
distinct longitudinal line, which I name the posterior Bank- 
sian line. This line is f. inst. very distinct in species of 
the Acanthaclisini. In the Palparid-group M2p fuses 
with Cuz, and from that point a “recurrent” nervure arises. 
The apical part of this recurrent nervure runs parallel to M 2a. 
In the forewing Cw forks close to the base of the wing. 
Cu has almost the shape like M 2 in the hindving; it forks 
at some distance from the base of the wings, and the anterior 
branch, Cara, runs parallel to M7. The posterior branch, 
Cuja; runs in a more or less oblique direction to the 
hind margin. Cuza emits a series of branches, running in 
an oblique direction to the hind margin. In many forms these 
branches together with a series of crossveins form a more 
or less distinct longitudinal line, the posterior Banksian line”).
