second joint reaching base of antenne, with smooth appressed scales, some- 
what loose beneath towards apex, terminal joint shorter than second, 
slender, recurved. Thorax smooth. Forewings elongate, moderate, apex 
obtuse, hindmargin somewhat concave or rounded, oblique. Hindwings 
slightly narrower than forewings, elongate-ovate, hindmargin rounded, cilia 
1 to 2. Abdomen moderate. Posterior tibie clothed with rather short 
hairs above. Forewings with vein 7 to costa, 2 from rather considerably 
before angle of cell. Hindwings normal. i 
Nearly allied to Œcophora, from which it is separated by the absence of 
the basal pecten of antennæ, differing also in the greater remoteness of vein 
2 of the forewings from the angle of cell. The forewings are more tri- 
angular, and the hindmargin sometimes markedly concave. The genus is 
` endemic in New Zealand, so far as is known, and has attained some degree 
of development ; it is doubtless an offshoot of GZcophora.
