Liornuna, n.g. 
[From A£&wc “ smooth,” and QvAa£ “a ease."] 
Male.—Head small; head and thorax pilose; proboscis none; palpi 
obsolete; antenne as long as the thorax, bipectinate, the branches very 
long towards the base, from whence to beyond the middle the branches 
abruptly decrease in length, and thence gradually decrease to the tip ; body 
robust; abdomen extending more than half its length beyond the hind 
wing; stout near the thorax and tapering thence to the tip; legs slender ; 
femora and tibie pilose ; fore-wings diaphanous, thickly clothed with scales, 
narrow, nearly straight along the costa, slightly rounded at the tips, hind 
margin very oblique; discoidal cell closed by a transverse angular nervure, 
the angle of which projects inwards ; median nervure emitting four branches, 
the branches nearly equidistant from each other, the second springing from 
the first at the point of junction of the transverse nervure. Between the 
median nervure and the inner margin are two nervures which unite in the 
dise and form one nervure from thence to the hind margin; discoidal 
cell divided longitudinally by two rather indistinct veins ; hind-wings with 
discoidal cell closed by a transverse irregular nervure and divided 
longitudinally by a forked vein; median nervure emitting four branches, 
the first of which springs from the second at about one-third of the length 
of the latter, which is abruptly curved at its base ; the second branch about 
twice further from the third than from the first. 
Female.—Apterous. 
I cannot, from authorities at hand, find a description of any genus of 
this family entirely applicable to this insect. The nearest appears to be 
the genus Metura, described in the Catalogue of Lepidoptera in the British 
Museum. 
‘Liothula omnivora, n.s. 
Male.—Fuliginous. 
Expanse of wings—14:5 lines. 
Length of body— 8 lines. 
Hab.—Canterbury, New Zealand, especially in the neighbourhood of 
istchurch. 
Fig. A represents the male perfect insect. Larva varying from light 
to dark dull brown, mottled with dirty white, sometimes with a pinkish
