Subfamily PERIPSOCINAE. 
To the characters given on p. 187 should be added the following : Ptero- 
a not connected with R by a cross-vein. Rs and M in forewing 
either meeting at a point or fusing for a short distance. 
e genera of this subfamily found in New Zealand may be at once 
recognized by the complete absence of the cubital loop in the forewing. 
Only two such genera are at present known, and these may be separated 
by means of the following key :— 
Rs = М fused for a short distance in both wings; ptero- 
stigma of normal Es with the ponere margin waved Peripsocopsis n. g. 
(Genotype, socopsis maoricus n. sp.) 
Rs and M meeting at one » point only in orewing, and connected 
by a cross-vein in hindwin ga ow —Á 
with the posterior margin straight .. Ectopsocus McLachlan. 
Genus Ecrorsocus McLachlan. 
Characters as given in the above key, with the addition that the wings 
are without a fringe of hairs, the veins of the forewing either quite hairless 
or with only a few very minute hairs _ some of them, and the wing- - 
membrane is minutely punctate all o
