Art. XII.—Notes on New Zealand Geometrina.
[Read before the Philosophical Institute of Canterbury, 6th October, 1887.]
I have collected here such notes of additional localities and descriptions of new species as have accumulated since the publication of my former papers on the group. These bring up the number of recognized species to 113. To those who are desirous of discovering new species of this group, I would recommend (1) examination of the forest country north of Auckland; (2) searching unexplored mountains, at about 4,000 feet, especially in the extreme south; (3) the study of the genus Pasiphila; in the closely-allied genus Eupithecia the numerous similar species are frequently only obtainable by breeding, the small larvæ feeding principally in flower-heads or shoots and requiring special search; the presumption of similar habits here is very strong.
I hope before long to have made sufficient progress with the study of exotic material to modify and improve the classification of the group, but in the present paper I have only touched on it slightly.
Prob. megaspilata, Walk.
Also from Auckland.
The following new species differs in some respects (small points of neuration, noted in the specific description) from A.
euclidiata, but I consider that the two species may at present be advantageously included in the same genus. The relationship of this to Notoreas is thereby rendered so strong that I think the two genera must be placed in juxtaposition.
Arct. chrysopeda, n. sp.
Male, female.—16–20 mm. Head, palpi, antennæ, thorax, abdomen, and legs black, irrorated with ochreous-yellowish or ochreous-whitish. Antennal pectinations of male: a, 2,; b, 3. Forewings with hindmargin rather obliquely rounded; 6 out of 9, 7 from above or below angle of areole, 11 from or below angle of areole; dark fuscous, or dark ochreous-brown; base some-what irrorated with orange; four orange fasciæ, tolerably equidistant; first linear, slightly curved; second narrow, almost straight; third rather narrow, forming a short obtuse angle inwards below middle; fourth subterminal, linear, sometimes interrupted or nearly obsolete, irregularly subdentate; some-times a discal spot partially indicated by fine orange margins: cilia brown, with obscure darker fuscous quadrate spots on basal half, alternating with obscure whitish spots on terminal half. Hindwings with colour, markings, and cilia as in forewings, but first fascia absent; second unevenly angulated in middle; third broader, sometimes preceded by a fine additional orange line; fourth broader in middle. Under-surface similar to upper, but orange markings broader and lighter; cilia barred throughout with white.
Mount Arthur (4,000 feet), in January; six specimens.
Epiphr. undosata, Feld.
Also from Napier, Mount Arthur (2,700 feet), and Lake Wakatipu.
Epic, rubropunctaria, Dbld.
Also from Auckland and Napier.
I am now aware that I confounded three species together under the head of P. bilineolata, and that there are also several other species of the genus; also, that (so far as is known at present) the New Zealand species are all endemic. My previous description may therefore be regarded as cancelled, and I now give amended descriptions of those forms known to me. I am much indebted to Mr. A. Purdie for sending me specimens of some of these; there are doubtless others to be discovered. Besides the New Zealand species, I have three (or perhaps four) from Australia, and one from Tonga and the Marshall
Islands; the genus is not yet known elsewhere. The character of the ciliation of the antennæ in the male separates the genus into three well-marked natural sections: one Australian and the Tongan species belong to section B; the other Australian species belong to section C. In all the New Zealand species, vein 6 of the forewings rises from a point with or near below 9 (varying to this extent within the same species); veins 3 and 4 of the hindwings are remote and tolerably parallel; 6 and 7, stalked.

Wellington and Christchurch, in February; four specimens.
Pas. lichenodes, Purd.
Through the kindness of Mr. Purdie I have received a specimen of this very distinct species, which is much more neatly marked than any other of the genus; I do not, however, describe it, as I make no doubt that Mr. Purdie's own description (which has not yet reached my hands) from bred specimens is much more complete and satisfactory than anything I could furnish. The palpi are 2; ciliations of antennæ in male ½.
Dunedin, in January; taken and bred by Mr. A. Purdie.
§ C. Antennæ of male wholly naked.

Napier, Wellington, and Nelson, from December to March; tolerably common.
Pas. inductata, Walk.
(Coremia inductata, Walk., 1322; Scotosia subitata, ib., 1362.)
This is a distinct species; but I have only seen the British Museum specimens, and am unable to say to which section it belonges, or to give a proper description. The hindmargin of the forewings is more bent, and the hindwings are narrower than in any other species; ground-colour light reddish, with the margins of the median band formed by distinct black lines.*
Structure quite as in Pasiphila, except that in male the forewings have a tuft of scales or dilation on costa (variously formed in the different species).
There are four Australian species, besides the one from New Zealand; the latter approaches most nearly to Pasiphila, of which the genus is a development. The generic name was originally written by Butler as Phrissogonus, which is orthographically so horrific in formation that I have been obliged to reform it correctly.
Phrix. denotatus, Walk.
(Scotosia denotata, Walk., 1361; Phibalapteryx parvulata, ib., 1721.)
Male, female.—16–18 mm. Head, palpi, antennæ, thorax, abdomen, and legs dark fuscous, sometimes slightly mixed with pale ochreous; palpi 2; antennæ of male stout, quite naked; apex of tarsal joints ochreous-whitish. Forewings with costa moderately arched, hindmargin obliquely rounded; in male with a small glandular dilation on costa beyond middle, beneath
[Footnote] * Larentia infusata, Walk., 1199, and Eupithecia inexpiata, ib., 1708, are specimens of this genus, but are, in my opinion, too much worn for identification.
which is a naked transversely striated longitudinal mark occupying space between veins 10 and 12, these veins being somewhat distorted; rather dark fuscous, with numerous very obscure waved darker lines, more or less marked with black on veins; sometimes one or two irregular whitish-ochreous fasciæ preceding median band; anterior edge of median band undefined, posterior edge from before ⅔ of costa to ⅔ of inner margin, blackish, obtusely angulated in middle, with a marked sinuation above angle, rendered conspicuous by a white crescentic mark following it, sometimes followed by a whitish-ochreous patch: cilia light fuscous, with a darker line, base spotted with dark fuscous, terminal half whitish-fuscous. Hindwings with hindmargin unevenly rounded, sinuate above middle; fuscous, with waved darker lines; posterior edge of median band angulated in middle; cilia as in forewings.

Hindwings whitish-ochreous, with faint darker greyish-tinged lines; a median band of four more distinct cloudy grey lines, first three straight, fourth well-marked, rather dark fuscous, waved, somewhat prominent in middle, beneath confluent with third; a faint white subterminal line; cilia pale whitish-ochreous, with a faint greyish line tending to form spots.
Mount Arthur (4,500 feet), in January; one specimen. It is conceivable that this may be the other sex of the following species, but they are very dissimilar, and I do not at present think it probable.
Lar. bryopis, n. sp.
Male.—29–32 mm. Head, palpi, thorax, abdomen, and legs pale greyish-ochreous, slightly greenish-tinged, irrorated with blackish. Antennæ whitish, annulated with black.

Hindwings ochreous grey, with waved darker grey transverse lines, except towards base; a dark grey discal dot before middle; posterior edge of median band formed as in forewings, followed by an obscure whitish line and somewhat paler band; hindmarginal dots and cilia as in forewings, but more obscure,
Mount Arthur (4,500 feet), in January; not uncommon. Nearest allied to L. beata.

Hindwings fuscous-whitish; a median band of four cloudy greyish lines, bent near costa; a cloudy grey spot above anal angle; cilia fuscous-whitish (imperfect).
Whangarei; one specimen in December. Immediately recognisable by the peculiar form of forewings.
Lar. falcata, Butl.
This appears to be a good species, allied to L. camelias, but with costa of forewings less arched posteriorly, and posterior edge of median band practically straight, not bent near costa; also much darker in general colouring. I have not yet seen any specimen except the original type.
Lar. chorica, n. sp.
Female.—25 mm. Head, palpi, antennæ, and thorax light brownish-ochreous. Abdomen yellow-ochreous, margins of segments mixed with white and black. Forewings with costa sinuate, hindmargin somewhat sinuate beneath apex, obliquely
rounded; brownish-ochreous; a very slender, curved, whitish line rather near base, preceded by a small blackish spot on costa; a moderate white median band, tinged with grey, towards inner margin, enclosed by two narrow, fuscous, blackish-edged, subdentate fasciæ externally margined with slender white lines, first from ⅓ of costa to before middle of inner margin, somewhat curved, attenuated above inner margin, second from ⅔ of costa to ¾ of inner margin, slightly curved, middle third forming a strong triangular round-toothed projection marginally suffused with black; a faintly traceable clearer white discal spot in centre of band; a slender subdentate subterminal white line; a blackish fuscous spot, finely sprinkled with white, extending along hindmargin from near apex to middle, bordered by subterminal line; an interrupted black hindmarginal line: cilia pale ochreous spotted with white and blackish (imperfect).

Lar. cinerearia, Dbld.
Also from Whangarei, Auckland, and Nelson (to 4,000 feet).
Not. mechanitis, Meyr.
Also from Mount Arthur (4,000 feet).

Stath. anceps, Butl.
Also from Mount Arthur (4,000 to 4,500 feet).
Das. partheniata, Gn.
Also from Wellington and Mount Arthur (4,000 feet), in January.
Dichr. nigra, Butl.
From an examination of the original type, and also of other specimens taken by Mr. G. V. Hudson near Wellington, I am able to affirm that the insect which I formerly identified with this species is really a distinct species, to which a name is attached below. D. nigra is markedly larger, blackish, without any white suffusion, the markings obsoletely darker. Wellington is at present the only authenticated locality.
Dichr. gypsotis, n. sp.
(Cacopsodos niger, Meyr., “Trans. N. Z. Inst.,” 1883, 94 (nec Butl.)
The species is described under the above reference, and is recognisable by the white ground-colour.
I propose to regard the Œnochromidœ as defined by having vein 8 of the hindwings wholly free, whilst in the Acidaliadœ it is closely appressed to upper margin of cell near base; this genus is therefore to be referred here.
Xyridacma, n. g.
Face smooth. Palpi rather short, porrected, with appressed scales, second joint somewhat thickened. Antennæ in male somewhat compressed laterally, minutely ciliated (¼). Thorax rather hairy beneath. Forewings with vein 10 touching 9 at a point, 11 anastomosing with 12 and then with 10 at a point. Hindwings with veins 6 and 7 approximated at base.
Xyr. hemipteraria, Gn.
(Hemerophila hemipteraria, Gn., ix., 220, pl. vi., 2.)
Male.—29 mm. Head whitish-ochreous, face brownish, a fuscous bar behind fillet. Palpi dark fuscous. Antennæ and thorax whitish-ochreous, brownish-tinged. Abdomen whitish-ochreous, with some dark fuscous scales tending to form apical bands on segments. Legs dark fuscous (posterior pair broken). Forewings with costa slightly arched, hindmargin slightly sinuate beneath apex, bowed, oblique, subdentate; whitish-ochreous, brownish-tinged, with fine scattered blackish scales
towards costa and hindmargin; lines slender, brownish, first from ⅓ of costa to before ⅓ of inner margin, angulated near costa, second from costa near apex to inner margin beyond middle, slightly sinuate, marked with minute blackish dots on veins; second line preceded by a fainter similar line, and towards inner margin by another; a black discal dot beyond middle; subterminal line pale, waved, preceded and followed by darker shades, above middle preceded by two small subcrescentic blackish spots: cilia whitish-ochreous, faintly spotted with brownish. Hindwings with apex acute, projecting, hindmargin almost straight, waved; whitish-ochreous, brownish-tinged, with scattered blackish scales; a cloudy fuscous line from middle of costa to middle of inner margin; four fuscous lines parallel to hindmargin, first straight, second and third slightly waved, third marked with blackish above middle, fourth suffused into hindmargin; cilia as in forewings.
Auckland and Wellington, in December; two specimens. I have no doubt that this curious insect is really Guénée's species; he was not acquainted with the locality of his specimen, merely stating his belief that it was “Oceanian.” The form of hindwings is unique, so far as I know.
Boarmiadæ. Zermizinga, Walk.
Zerm. indocilis, Walk.
This species occurs also in South-east Australia.
I find that the genera Zylobara, Butl., and Pseudocoremia, Butl., are untenable, being not sufficiently distinct from this; the characters of neuration on which they depended are found to vary within the limits of the same species. I include, therefore, under this genus the five species panagrata, Walk., melinata, Feld., productata, Walk., lupinata, Feld., and fenerata, Feld.
Boarm. panagrata, Walk.
Also from Whangarei, Auckland, Wellington, and Dunedin.
Boarm. productata, Walk.
Also from Whangarei, Auckland, Napier, and Lake Wakatipu.
Boarm. lupinata, Feld.
Also from Nelson.
Boarm. fenerata, Feld.
Also from Auckland and Wellington.
I am rather disposed to think that the genera Detunda, Walk., and Epicasis, Meyr., ought to be merged in Declana; the neuration varies in each species, and to a certain extent within the limits of the species, and is probably here to be regarded as of specific value only; the genus would be sufficiently recognisable as a whole by the peculiar palpi. But I have not been able to examine many individuals, and shall be glad if others would look into the question.
Gon. nelsonaria, Feld.
Also from Wellington.
Chal. pelurgata, Walk.
Also from Whangarei, Wellington, and Nelson, in December.
The genus Stratocleis, Meyr., is not sufficiently distinct from this, and should be united with it.
Azel. gallaria, Walk.
Also from Wellington and Dunedin, in November and January.
Azel. fortinata, Gn.
Also from Wellington and Dunedin, in December.
Drep. muriferata, Walk.
Also from Whangarei, Wellington, and Nelson, in December and January.
