another on middle of hindmargin, and sometimes a larger one on inner 

 margin before anal angle, sometimes all partially confluent ; a slender 

 cloudy blackish transverse line from costal spot to anal angle, irregularly 

 sinuate, and strongly dentate inwards beneath costa : cilia whitish, with 

 two cloudy dark grey lines. Hindwings grey, apex and hindmargin 

 darker ; cilia grey-whitish, with a faint darker line. 



At once distinguished by the white head and white ground-colour of the 

 forewings ; in the form of the anterior line it approaches T. spartodeta. 



Hamilton, Wellington, and the Bealey Eiver, in January ; four 

 specimens.

Minor, alis ant. albidis, virescenti-suffusis, fascia ad basim, triangulo 

 costa? medio maculaque apicis griseis, linea antica transversa acute angulata 

 nigra ; post, griseis. 



Male. — 13i-14i mm. Head, pale whitish-ochreous. Palpi ochreous- 

 whitish, second joint dark fuscous on basal half, terminal joint with a dark

 round-pointed, hindmargin very obliquely rounded ; whitish, with nume- 

 rous scattered ochreous-green scales, forming an irregular suffusion, and 

 also partially suffused with light greyish; a small blackish spot at base of 

 costa ; basal third of costa dark grey : a slender sharply defined black line 

 from i of costa to ^ of inner margin, very acutely angulated outwards in 

 middle, becoming obsolete on margins, preceded by a tuft of raised scales 

 above and below middle ; a small triangular dark grey patch on middle of 

 costa, beneath which are two raised tufts of scales almost completely 

 margined with black, upper one greenish, lower white ; lower tuft almost 

 connected with inner margin beyond middle by some black scales ; a small 

 cloudy grey spot on costa at f , whence a partially obsolete blackish line 

 proceeds to anal angle, sharply angulated inwards beneath costa ; a cloudy 

 grey spot on upper half of hindmargin ; two or three ill-defined blackish 

 dots round apex, sometimes confluent : cilia grey- whitish, greenish-tinged, 

 with a cloudy grey line obscurely spotted with blackish. Hindwings grey ; 

 cilia grey-whitish, with a cloudy grey line.

 ochreous-green suffusion of the ground-colour. 



Palmerston, and at the foot of the Otira Gorge, in January and Feb- 

 ruary ; three specimens.
