and a median line pale iridescent grey ; a sinuate row of black dots beyond 
middle, generally distinet only on inner margin; an incomplete grey or 
greenish subterminal line. 
Very variable in colour and distinctness of marking. A singular-looking 
species; at rest the wings are not flat, but peculiarly folded longitudinally. 
Christchurch, Akaroa, and Dunedin ; common amongst bush, from 
December to February ; fifteen specimens. 
18. PASIPHILA, N. g. : 
Face with a cone of scales. Palpi rather long, roughly scaled above and 
beneath, porrected. Antenne in male biciliated with fascicles of cilia (24). 
Forewings with vein 6 from a point with 9, 7 from below angle of areole, 
10 anastomosing strongly with 9, 11 out of 10, running shortly into 12. 
Hindwings with veins 6 and 7 stalked, 8 anastomosing with 7 from near 
base to near transverse vein. 
Nearly allied to Eupithecta, Curt.

Male, female.—16—24 mm. Forewings moderate, costa sinuate or arched, 
hindmargin rounded, crenulate ; whitish, whitish-ochreous, reddish-ochre- 
ous, light fuscous, greyish, or green, sometimes coloured with alternate 
bands; numerous irregular sinuate dentate dark fuscous or green lines, 
sometimes partially obsolete ; some beyond middle are angulated in disc ; 
sometimes a broad median band suffused with fuscous, and irregular spots 
towards anal angle, middle of hindmargin, and on costa before apex ; some- 
times dise wholly occupied by a very large irregular transverse snow-white 
blotch. Hindwings short or moderate, hindmargin rounded, erenulate, 
sometimes emarginate towards inner angle; varying from whitish to 
fuscous or dark grey ; a dark fuscous discal dot ; numerous curved dentate 
dark fuscous and green lines, only distinct towards inner margin, one 
beyond middle stronger and blackish. 
Extraordinarily variable ; the shape of wing varies a good deal, and the 
colour infinitely ; the lines are, however, always identical in form when 
perceptible. All the forms are connected by insensible gradations, and I 
consider it certain that there is only one New Zealand species of this genus. 
The varieties do not appear local as a rule, but Mr. R. W. Fereday found a 
constant dark bluish-grey variety frequenting rock-faces on Mount Hutt at 
2,500 feet; it is without doubt a variety only.
