Hoiotype: No. In 45518 (obverse), British Museum (N. H.), 
London. Collected in Upper Permian, Belmont, N.S.W. 
Genus Elytrathrix, new genus 
Fore wing: tegminous, darkly pigmented; sutural margin nar- 
row; wing surface covered by dense granulation and sparse tubercles, 
which become very conspicuous in the basal part; setae bordering the 
yard in the presence of conspicuous, large tubercles, developed in the 
costal area; costal expansion projecting, covered by large tubercles; 
main veins strong in the basal third, but completely lacking in the 
more distal part of the wing. 
Relationship. Elytrathrix n. gen., differs from Permophilus Till- 
yard in the presence of conspicuous, large tubercles, developed in the 
basal third of the wing and on the costal expansion. 
Stratigraphic occurrence: Upper Permian of Australia ( N.S.W. ). 
Type-species: Elytrathrix hirsuta n. sp.

Fore wing: about 15 mm. long and 5 mm. broad; granulation 
dense, coarse; tubercles at the base numerous, large, pointed, irregu- 
larly covering the veins, the areas between veins, and costal expansion ; 
setae distinct, strong, especially near the anterior margin; costal ex- 
pansion projecting, circular; apex in the longitudinal axis of the 
wing; anterior margin strengthened in the basal third, not concave 
before apex; posterior margin very strong; veins reduced but very 
strong, especially in the anal area; 4 anal veins.

Stenelytridae, new family 
Diagnosis. Fore wing: tegminous, almost flat, darkly pigmented; 
sutural margin bordering the whole posterior margin; wing surface 
covered with dense, fine granulation; setae forming a patch in the 
subcostal area and perhaps also along the proximal part of the pos- 
terior margin; costal expansion large, projecting; apical part nar- 
rowed and prolonged; anterior margin strengthened; venation of 
normal protelytropterous pattern; Rs originating late; subcostal area 
unusually broad. 
Relationship. The family Stenelytridae is closer, on the basis of
