to costa. Hindwings moderate, hindmargin projecting in middle, crenate ; 

 deep ochreous-yellow, hindmargin more reddish-tinged, base paler ; some- 

 times suffused with light purplish-grey, except an ochreous-yellow sub- 

 terminal fascia. 



Apparently somewhat variable in colour. 



Wellington, Christchurch, and Akaroa, amongst bush, in November and 

 January ; three specimens in the collections of Mr. E. W. Fereday and the

 Face with projecting scales. Palpi moderate, triangularly scaled, por- 

 rected. Antennae in male stout, strongly dentate, teeth moderately ciliated 

 (f). Forewings with vein 6 rising out of 9, 7 from angle of areole, 10 ana- 

 stomosing moderately with 9, 11 anastomosing strongly with 10, 12 free. 

 Hindwings normal. 



This genus occurs also in Australia.

 (Aspilates (?) subochraria, Dbld., Dieff. N.Z., ii., 285; Camptogramma subochraria, Butl., 

 Cat., pi. iii., 16; Camptogramma strangulata, Gn., x., 423; Camptogramma fuscinata, 

 Gn., E.M.M., v., 92.) 



Male, female. — 25-28 mm. Forewings moderate, hindmargin rounded ; 

 yellow, faintly striated with darker ; costa narrowly suffused with purplish- 

 fuscous ; a well-defined black discal dot; a narrow purplish-fuscous sinuate 

 fascia or line beyond middle, posteriorly well-defined ; anteriorly suffused, 

 and dilated on inner margin ; a suffused fuscous hindmarginal band, pre- 

 ceded by one or two faint dentate fuscous striae. Hindwings moderate, 

 hindmargin rounded ; yellow, paler towards base, more ochreous or reddish- 

 tinged posteriorly. 



Var. fuscinata. All wings more or less strongly suffused with light 

 purplish-fuscous, fascia darker. 



Constant except in respect of the fuscous suffusion. 

 Wanganui, Nelson, Christchurch, Mount Hutt, Dunedin ; very common 

 in open ground, frequenting the tussock-grass, from November to April ; 

 common also in Tasmania and Victoria ; forty-eight specimens. The 

 variety fuscinata is worth naming, as it appears to be confined to New 

 Zealand ; Mr. Fereday states it to have been formerly locally abundant in 

 the swampy plains ; but it shades gradually into the type. 

 27. Ars. prionota, n. sp.

 in male crenate, in female dentate ; light-ochreous ; numerous indistinct 

 sinuate dentate fuscous or dark fuscous striae ; in male costa and hind- 

 margin suffused with dull light green ; a broad median band indistinctly
