III. Myrmeleonidae. 



As far as I know only the Neomyrmeleonidae are repre- 

 sented in the Australian fauna; but here we meet with many 

 old and interesting forms. In continuation of my paper 

 »Help-notes towards the determination and the classification 

 of the European Myrmeleonidae»^ I give here in a short 

 and tabular form my view with regard to the systematic 

 of the Austrahan fauna, but only concerning the material 

 here present. 



1. Rs in the hindwing arises close to base of wing and al- 

 ways before fork of M^. Only one (very seldom two) 

 crossvein in the radial area before origin of Bs. 



Dendroleoninae 2. 



— Rs in the hindwing does not arise so close to base of the 

 wing and always further out than the fork of II^. Two 

 or more crossveins in the radial area before the origin 

 of Rs. Myrmeleoninae 4. 



2. In the forewing Rs arises before or just above the fork 

 of Gu^. The free basal part of Cwj ^s a rule rather long; 

 two or three crossveins between this part and Cu^, 2 A 

 and 3 A not coalescing. In the hindwing 2 ^ is always 

 present and distinct. One crossvein between lA and 2 A. 



Dendroleonini. 



— In the forewing Rs arises further out than the level of 

 the fork of Cu^. The free basal part of Cu^ short; mostly 

 only one crossvein between this part and Cu^. 2 A and 

 3 A coalesce at a point or for some distance. In the 

 hindwing 2 A is sometimes present, but not very distinctly. 

 Between lA and 2 A no crossvein present 3. 



3. Cw,p and Cu^ in the forewing are running parallel with 

 Cu\2^ and with the hind margin of the wing. Creagrini. 



— Ctfcip and Cii^ do not run parallel to Cuu or to the hind 

 margin. Formicaleonini.
