TiLLYARD.—Psocoptera, or Copeognatha, of New Zealand. 193 
Thorax dark brown, the notal sutures pale testaceovs. Legs testaceous. 
Wings held at a rather broad angle over the back in repose, so as to 
approach the horizontal position much more than is usual in this order; 
subrectangular. Membrane of both wings minutely punctate, hyaline, the 
veins dark brown, except only the basal pieces of Rs and M, which are 
pale testaceous. In the forewing there is a dark blotch at either end of 
the stigma, and smaller blotches at the apices of all the veins and also at 
the point where Rs and M meet. Clavus of forewing short, about as long 
as the stigma. Cu, ending up at about half-way along the posterior border 
of the wing. Stalk of Rs about as long as Ё, +5, the dichotomy of Rs 
occurring exactly below the end of the stigma. М, arising very little distad 
from 3- 
Habitat.—Abundant in many localities throughout New Zealand, both 
in the bush and amongst orchard-trees. Exceedingly abundant around 
Nelson. 
Type.—Holotype (Nelson, 13th April, 1921, R. J. Tillyard) and serie 
of paratypes in Cawthron Institute collection. 
This interesting little insect closely resembles the Australian E. briggsi 
is much longer than Ra+s. 
Mier End. was separated from Ectopsocus McL. on account of 
its hairy wings and some slight differences in the venation. Thus it will 
be seen that, in possessing a few very small hairs on the veins, our new 
species serves in some measure to reunite these two genera. It has been 
placed in Ectopsocus because its venational scheme agrees with that of this 
genus. 
| Genus PERIPSOCOPSIS П. g. 
Characters as given in the key on p. 192, with the addition that the 
wings are entirely hairless and the membrane of both wings minutely 
punctate all over. 
Genotype.—Peripsocopsis maoricus n. Sp. 
This genus is related to Peripsocus Hagen, agreeing with it closely 
in its venational scheme, but differing from it in so far as Peripsocus 
has a fringe of hairs on both wings amd the veins of the forewing are 
hairy. |
