(For lettering see figs. 1 and 17.) 
Type.—Holotype female in Cawthron Institute collection, also series of 
paratypes. 
Locality.—Holotype taken at Nelson, 6th January, 1921, by Mr. A. 
Philpott. I have also taken specimens at Rotorua, Karori, and Dunedin. 
There are also several other species of this genus to be found in New 
Zealand, but the working-out of them will require the collecting of much 
more material, and therefore they are left for a later paper. 
In concluding this paper I desire to thank Mr. б. V. Hudson, F.ES., 
F.N.Z.Inst., for giving me the opportunity of examining his type of 
Leptoperla grandis, and for giving me specimens of each of the four species 
of Leptoperla described by Hare.

Tur family Berothidae includes only five genera of lacewings, containing 
species which are very rare and widely scattered about the earth. Three 
of these genera—viz., Spermophorella, Trichoma, and Stenobiella—are Aus- 
tralian, but no representative of the family has so far been recorded from 
New Zealand. In this paper the first occurrence of the family for New 
Zealand is recorded, in the form of a new genus an ies. 
The family Hemerobiidae is world-wide, consisting of small lacewings 
whose larvae feed on aphids and psyllids. Two genera have been recorded
