The right forewing of the type has four well-developed branches to M, 
while the left forewing is normal, with only three branches. 
Habitat.—Dun Mountain, Nelson, 3,000 ft. ; taken by Mr. A. Philpott 
on the 9th February, 1921. A single specimen only. 
Type.—Holotype in Cawthron Institute collection. 
Family MYOPSOCIDAE. 
Antennae with 13 joints. Ocelli present. Maxillary palpi four-jointed, 
the last joint of normal elongate-oval shape. Tarsi three-jointed, the 
basal joint longer than the other two together. Venation of the normal 
type, the forewing with Cu, and 1A ending together. Cubital loop of fore- 
wing present, either just touching M or fusing with M for a short distance. 
This family is divided into two subfamilies, as follows :— 
Forewing with a cross-vein between pterostigma and Rs .. Subfamily PROPSOCINAE. 
Forewing without a cross-vein between pterostigma and Rs Subfamily МҮОРЗОСІХАЕ. 
Only the latter subfamily occurs in New Zealand. 
Subfamily MYOPSOCINAE. 
Genus Mvorsocus Hagen. 
In this genus the median vein is much zigzagged in both wings. In 
the forewing M runs obliquely upwards to meet Rs, then bends sharply 
downwards, at right angles to its former course, until it reaches the top of 
the cubital loop, when it again bends obliquely upwards and runs to the apex, 
dividing into three branches. The basal piece of Rs, the middle piece of 
M, and the distal piece of Cu,, lie almost in one straight line crossing the 
wing obliquely. In the hindwing M fuses with Rs for a short distance, 
then leaves it almost at right angles and curves strongly round to run 
longitudinally to a point below the apex. The forewings of the species of 
this genus are more or less heavily marked with brown, grey, or fuscous. 
Genotype.—M yopsocus lugens Hagen. 
Two species of this genus have been described from Australia, one from 
New Guinea, and one from New Zealand.

_ This species has already been well described by Kolbe and Hutton. It 
is very much larger than any other known New Zealand Psocopteron, 
and can be at once recognized by the dark forewings, mottled brown or 
fuscous, as shown in Plate 18, figs. 5, 6. Points that should be noted are 
_ the following: The males are much smaller and darker in colour than the
