and a median line pale iridescent grey ; a sinuate row of black dots beyond 

 middle, generally distinct 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. 



13. Pasiphila, n. g. 

 Face with a cone of scales. Palpi rather long, roughly scaled above and 

 beneath, porrected. Antennre in male biciliated with fascicles of cilia (2^). 

 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 Eupithecia, 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 disc wholly occupied by a very large irregular transverse snow-white 

 blotch. Hindwings short or moderate, hindmargin rounded, crenulate, 

 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. E. 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.
