P. ESBEN-PETERSEN, NEUROPTERA AND MECOPTERA. 5 



4. In the hindvving 2 ^ is present as a short thickened ner- 

 vure, distinctly separate from the hind margin; its apical 

 part is curved upwards, and it ends into 1 A. Body and 

 legs stout and strongly haired. Acanihaclisini . 



— In the hindwing 2 A \q mostly running directly into the 

 hind margin and therefore not observable (in Callistoleon 

 2^ is running free of the hind margin as a weak nervure, 

 and it ends into 1 A). Body and legs not very stout or 

 haired. Myrmeleonini. 



1. Dendroleoniiii. 



This tribe seems to be very well-represented in the Au- 

 stralian fauna, apparently better there than in any other 

 fauna of the world. Låter on a sub-division may probably 

 be necessary. The genera Austrogymnocnemia and Acaniho- 

 plectron occupy a special position in the tribe. 



Key to the genera here mentioned. 



1. Rs arises long before fork of Cu^ in the forewing and long 

 before fork of M2 in the hindwing 2. 



-- Rs arises above fork of Cu^ in the forewing and just be- 

 fore fork of if 2 in the hindwing 5. 



2. Hind margin of the wings with one or two excavations. 

 Wings with brownish black or golden shining spöts or bands. 



Periclystus. 



— Hind margin of the wings without excavations. No golden 

 shining spöts or bands 3 



3. Spurs present 4 



— Spurs absent. Forewings a little shorter than hindwings 

 and with rounded apex. Nervature very dense. Anterior 

 Banksian line present in the forewing. Chrysoleon. 



4. The direction of CU2 in the forewing undulating. Anterior 

 Banksian line present. Rather broad-winged species. 



Glenoleon.
