Mzvnick.—On New Zealand Micro-Lepidoptera. 25 
base externally brownish - ochreous. Labial palpi long, white, externally 
greyish-ochreous, more fuscous towards apex. Antenne dark fuscous. 
Thorax light ochreous, with a more or less distinct suffused white central 
longitudinal stripe, sometimes obsolete. Abdomen ochreous-whitish, more 
ochreous towards base, apex white. Anterior and middle legs whitish- 
ochreous, suffused beneath with dark fuscous ; posterior legs whitish. 
Forewings moderate, in female narrow, costa moderately arched, less 
strongly in female, slightly sinuate in middle, apex acute, in female 
rather produced, hindmargin rather strongly oblique, slightly rounded ; 
pale ochreous; a very slender white streak from base close beneath costa to 
apex, on posterior half broader and more suffused, in female broader and 
extending to costa ; veins towards hindmargin between median streak and 
costa more or less suffused with white, more strongly in female ; a rather 
narrow central longitudinal white streak from base to hindmargin, rather 
attenuated towards base, very slightly eurved towards hindmargin ; some- 
times a slender white streak along vein 1 towards anal angle; in female, 
veins somewhat suffused with white towards hindmargin beneath median 
streak; a very slender white streak along inner margin from base to beyond 
middle, posteriorly suffused : cilia shining white.  Hindwings very pale 
whitish-grey, in female white, hindmargin faintly ochreous-tinged ; cilia 
white. 
Differs from all the allied species by the clear pale ochreous ground- 
colour ; the white markings (except the central streak) are more suffused, 
the cilia clear white, and the hindwings paler, being quite white in female. 
In this and the allied species the central streak appears dark-margined 
in part, but the effect is illusory, and due to the presence of deep 
folds. 
Very common round Christchurch in November, December, February 
and March, seemingly attached to the tussock-grass.
