second joint reaching base of antennae, 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 

 -J to -§. Abdomen moderate. Posterior tibiae clothed with rather short 

 hairs above. Forewings with vein 7 to costa, 2 from rather considerably 

 before angle of cell. Hindwings normal. 



Nearly allied to (Ecojrfwra, from which it is separated by the absence of 

 the basal pecten of antennas, 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 (Ecophora.
