 surfaces the course of the median dark band of tiie hindwing is distinctive. Tiie highly developed (very heavily

A. regilla Philpott (-4li). 24 2.s mni. Very near pcrornaia. to which IMkyrick would with confidence miilld.

 end inclined to become whitish. 4th. (i. e.. outeiinost) complete band .'^lightly les.s angiilar, subterminal often 

 punctiform, in any case forming a streak-like or wcdge-shaped longitudinal mark in cellule 3; fringe with 

 the white spots narrowed and generally more tinged with yellowish. Hindwing with first dark band or line 

 slender, nearly straight. Under.side very sharjily marked: the subcostal sinus of the .subterminal line slightly 

 less deep than in perornata. Dun Mountain (Nelson) etc.: "not very common, but probably to be found 

 in all subalpine localities in the Nelson Province ' and reaching Mount Cook.

(Soo Vol. 4. p. 222: Vol. Iti. p. Sl.) 



Face with projecting scales or tuft below. Palpus moderate or rather strong, rough-scaled. Antenna 

 of J pectinate (sections A and B) or more or less dentate and ciliate (sectioii ( '). Forewing with areole double. 

 Hindwing with discocellulars oblicpie. 2nd radial arising before the middle. or in any case not behind the cell- 

 fold, Ist median not stalked. A genus of almost «-orldwide occurrence. very prominent in the New Zealand 

 fauna. Tyj^e of the genus: montavata Srhiff.

X. pantoea Tnrn. (24 h). Very variable, but mucli smaller than the other species of the section. the panloca. 

 pectinations long, especially tho.se of the outer series. Forewing glossy dark bro\\'n. with the median area little 

 differentiated. the cell-spot large. Hindwing paler. the principal lines indicated. In one aberration the cell- 

 spot is white or whitish. dark-outlined. In another the whole of the disc except the base, anterior part of median 

 band, and a terminal band are brown-whitish. Victoria: Lome (loc. typ.) and Ebor. — viridicans sulisp. jior.. virklinDis. 

 from Queensland National Park (3U0Ü feet), is very dift'erent in aspect but has the same structure and seems 

 clearly conspecific. "Distinctly green. with well-defined basal patch and median band fuscous-brown. but the 

 latter sometimes incomplete; minute white dots are sometimes present on the subterminal line" (TfRXER).

 and Victoria, type from Mount Kosciusko. (iöOi» feet. 



X. argocyma Turn. (24 1). Pectinations comparatively short and the proximal pair on each segment anjori/ma. 

 shorter than the distal imir. thus assimilating to the formation found in a few African Xanthorhoe. Coloration 

 and pattern also more normal for the genus than in either of the jireceding. Hindwing beneath with the dark 

 subterminal clouds at the radials and hindmargin stronger than above. The type cJ came from Mt. Kllery. 

 Victoria. Subsequent material from Mt. St. Bernard and Mt. Kosciusko sliows the ?$ (as also in the preceding 

 species) to be considerably smaller than the ,j.

 obsolete in its anterior part. South Island. New Zealand. at least from Christchurch to Invercargill; Hrüsox 

 adds one or two North Island localities. Frcquents rougli herbage in the vicinity of forests.
