oblique; white, closely and finely irrorated with dark grey; generally a 
slight brownish or ochreous tinge along basal two-thirds of costa, some- 
times extending over whole wing; sometimes a dark grey suffusion on 
middle of costa; a small dark fuscous elongate mark on inner margin close 
to base; a double indistinct dentate dark grey line from costa before middle 
to inner margin at 2, often wholly absent or obsolete ; a dark grey circular 
ring in disc slightly beyond middle, in centre of which is a dark grey 
elongate dot, both often absent, or the dot only visible; a double often well- 
defined dentate dark grey line from costa at + to inner margin before anal 
angle, shortly angulated inwards immediately beneath costa, and outwards 
above middle, often wholly absent; a dark fuscous hindmarginal line; a 
row of from six to eight small black dots on hindmargin : cilia light shining- 
grey, more or less distinctly narrowly barred with white, with a darker grey 
line near base, and extreme base white. Hindwings ochreous-grey-whitish, 
hindmargin narrowly suffused with light fuscous-grey ; cilia ochreous- 
whitish. 
Very variable, but very distinct by the narrow wings, grey colouring, 
and entire absence of white markings or longitudinal streak. ; 
Abundant on the hills round Christchurch in March; I have also seen 
specimens from Lake Guyon, which were somewhat larger, with the dark 
markings more intense.

Male.—26-27 mm. Head whitish, with a faint ochreous spot in middle

rounded ; grey, very slightly brownish-tinged ; a slender ill-defined central 
streak of white scales from base to beyond middle of disc, its extremity bent 
downwards and then sharply turned inwards to form a strong hook ; upper 
edge of this streak margined by a very slender dark grey line, forming an 
abrupt spot on extremity, lower edge margined by a dark fuscous-grey 
streak, filling up the hook ; a slender ill-defined sinuate longitudinal streak 
of white scales in dise from 3 to 4, its anterior extremity resting on upper 
margin of basal streak, its lower edge broadly and suffusedly margined with
