close irroration of dark grey scales, and distinctly ochreous- 

 tinged ; the black dots are also differently arranged. 



Three specimens taken in the swampy forest near Cambridge 

 and Hamilton, on the Waikato, New Zealand, in January. 

 Walker's type is unset, but certainly referable to this species. 



3. Oistophora n. g. 



Thorax smooth. Antennas of male hardly thickened towards 

 base, very finely ciliated. Palpi moderate, porrected, second 

 joint very roughly haired above and below towards apex, 

 terminal joint concealed. Posterior tibia* thinly haired above. 

 Forewings elongate, narrow, costa in male simple, moderately 

 arched, apex acute, hindmargin oblique ; surface with tufts of 

 rough scales. Hindwings broader than forewings, apex rather 

 produced ; a very large expansible tuft of long hairscales towards 

 base beneath lower median vein. Forewings with veins 7 and 

 8 separate, 7 running to hindmargin, secondary cell absent, upper 

 basal fork of vein 1 obsolete (?). Hindwings with 6 veins, 3 and 

 4 short-stalked from posterior angle of cell, 5 from upper angle 

 of cell to apex, 6 free. 



Related to Paramorpha, but abnormal in facies ; distinguishable 

 by the short palpi, and especially by the large expansible tuft of 

 hairs on the hindwings in both sexes.

$ $ . 8"- 8£". Head and thorax white, slightly mixed with

 Legs whitish, anterior and middle tibiae and tarsi suffusedly 

 banded with dark fuscous. Forewings very narrow, costa bent 

 towards apex, hindmargin straight, very oblique; ochreous- 

 whitish, irregularly irrorated with dark fuscous; costal edge 

 blackish towards base ; five short very oblique cloudy blackish 

 strigulse on costa between middle and apex, and one still shorter
