AUSTRALIAN NEUROPTERA. VI. * 
(By P. Ksben-Petersen, Silkeborg.) 
Amongst a lot of very interesting material of 
Australian Neuroptera, collected by Mr. L. Franzen, 
Brisbane, 1 have found some new and undescribed genera 
and species, it has given me very much pleasure to work 
out the material, and I express here my most sincere 
thanks to Mr. L. Franzen for the opportunity to examine 
these interesting Neuropterous insects. 
The following genera and species are described:— 
Franzenia irrorata, 11 . g. and n.sp, — Myrmeleontidae. 
Zachobiella submarginata, n.sp. — Hemerobiidae. 
Neurorthus brunneipennis, n.sp. — Sisyridae. 
Theristrielia stigma, n,g. and n.sp. — Mantispidae. 
Franzenia n.g. 
Antennae rather long, stout and strongly clubbed. 
Prothorax longer than broad. Legs of moderate length; 
femora, tibia and tarsus of fore and intermediate legs of 
equal length ; tibiae of intermediate legs strongly and 
conspicuously broadened. No spurs. Fore and hindwings 
nearly equal as to length and shape. In the forewing li 
arises close to the base of the wing and a little before the 
fork of (Til. Basal free part of Cu2 rather long; Cu2 
somewhat sinuate, and its apical tip curved upward and 
connected to < 'nip. 2A and 3A running free of each other, 
but connected to each other by two cross veins. No 
Banksian . line present, and no cross veins in the apical 
areas of the wings. In the hindwing one cross vein before 
origin of R. 
Bono type : Franzenia irrorata. 
This new genus has to be placed in the Demlroleonini. 
The best and most peculiar generic character is the broad- 
ened tibia of the intermediate legs. 
I take the liberty to name the interesting genus in 
honour of Mr. L. Franzen, who. has done so much in 
exploring the Neuropterous fauna of Australia.
