genus may be looked upon as the eldest or the most archaic 

 one in the Chrysopidae, and it may be placed in a sub-family 

 Dictyochrysinae. In the forewing of this sub-family M forks 

 regularly, and its two branches are running parallel for some 

 distance. No pseudo-media is present. In both pairs of the 

 wings the discal area is filled up irregularly by hexagonal 

 cells. In the forewing 2^ is forked. Two rows of cells be- 

 tween the pseudo-media (rather indistinct) and the pseudo- 

 cubitus in the hindwing. The rest of the Australian genera 

 of the family form a second sub-family, the Chrysopinae. In

the forewing of this sub-family M^ has an irregular direction. 

 Pseudo-media present. The discal area is filled up by more 

 or less quadrangularly formed cells. Series of gradate veins 

 present. Between pseudo-media and pseudo-cubitus in the 

 hindwing one row of cells. 2 A is unforked in the forewing. 

 The genus Chrysoj)a is undoubtedly the most specialized 

 genus in that sub-family. 



Below I give a table of the x^ustralian genera, known 

 to me. 



1. In the forewing M forks regularly, and its two branches 

 are running parallel at least for the distance of the length 

 of the two basal cells enclosed. No pseudo-media in the
