The basal part of Cu2 in the forewing is free, but Cu2 
coalesces with 7A close to its base, and at the point 
where it coalesces it emits a curved and forward-directed 
crossvein to Cu1. 2A runs wide apart 7A basally, and it 
coalesces with 3A in a point, or for a very short distance; 
before it coalesces, it is connected with ZA by a very con- 
spicuous crossvein, it is forked, but occasionally unforked. 
3A forked. In the hindwing Rs arises rather close to the 
base of the wing, or a little further out than the level of 
the fork of M2. JA long and forked. 2A rudimentary. 
The shape of the wings is rather exceptional. 
The breadth of the wings is almost the same from the 
base to the tip, which is regularly pointed. 
The Myrmecaelurini form a well-defined tribe. The 
free and basal part of Cw2 in the forewing is rather short, 
and from the point where it coalesces with 7A, a cross- 
vein is emitted to Cuz. 2A and 3A are coalescing in a 
point, or for a short distance. 2A unforked. 3A forked. 
In the forewing Rs arises further out wards than the level of 
the fork of Cz7, and in the hindwing the same takes place. 
In the hindwing 7A is forked; 2A rudimentary. 
Still we have to deal with the Myrmeleonini and the 
Acanthaclisini, the rest of the subfamily. A common cha- 
racter for both tribes is the apparent irregularity in the 
nervature of the anal part of the forewing. In the Myr- 
meleonini the Rs of both pairs of wings arises further out 
than the level of respectively the cubital and the median 
fork. In the forewing Cu2 is rather short and coalesces 
with 7A where it reaches the first crossvein emitted from 
Cuz, or a little further outwards. Basal part of 2A runs parallel 
with and very close to JA, and just at the point where it 
diverges from 7A, it coalesces with this nervure in a point. 
2A and 3A coalesce for a distance. 2A forked; 3A un- 
forked (?). In the hindwing 7A is well-separated from Cu 2 
basally, but connected with that nervure by a short cross- 
vein. 7A forked. 2A rudimentary.
