streaks laR rally. Legs yellowish white. Antennae, head, 
thorax; .abdomen and legs strongly haired. Membrane 
of wings hyaline; that of forewings yellowish tinged; but 
the apical .margin narrowly brownish shaded. Venation 
of wings brownish yellow; all the cross veins brown; tlfose 
of th<* disc of forewings dark brown and narrowly shaded.

Of the genus XeurortTius Costa (Xuovi stud. Ent. 
Oala.br. Hit. 32, 1863) two European and two Japanese 
species are known. The Japanese species, pnnetatus Nak. 
and fuscinervis Nak., differ from the European, fallax 
Kami), and iridipennis Costa, by the presence of some 
forked cross veins in the costal area of the forewings. In. 
that respect the Australian species is nearest allied to the 
Ja panese. 
Theristriella n.g. 
Fore tarsus with two claws. Prothorax closed be- 
low. M forks almost just below origin of Rs. its stem 
rather long and straight as in Theristria. In the fore- 
wing M 1 and 2, is connected to K5 by a short cross vein; 
in the hindwing this crossvein touches the stem of M. 
Cu forks regularly as in Theristria. In the forewing 1A 
and 3A is unforked; 2A forked. Costal area, of forewing 
rather broad. The pterostigma very short but very broad, 
opaque. When the wing is held against the light trace of 
one or two cross veins are visible in the pterostigmatical 
area. Few branches from R5. 
Genotype: Theristriella stigma n.sp. 
This new 7 genus is allied to Theristria Gerst. and Calo- 
mantispa Banks, and the three genera may be separated 
in the following way: — 
1. Wings long and rather slender. In the forewing 
the stem of M is straight and does not coalesce with R5. 
1A in the forewing unforked. Forewings without col- 
oured markings. 2. 
Wings short and broad. In the forewings the stem of 
M is curved, and it coalesces for a distance with the basal 
part of Rs. 1A in the forewing forked. Forewings with 
coloured markings. Calomantispa. 
2. Pterostigma of moderate width, but several times 
longer than broad, and with inconspicuous cross veins. 
Many branches from Rs, Theristria.
