Art. XIII.—Notes on New Zealand Pyralidina.

[Read before the Philosophical Institute of Canterbury, 6th October, 1887.]

Pyralididæ.
Diplopseustis, Meyr.

Ocelli present, concealed. Antennæ in male moderately ciliated. Labial palpi long, second joint porrected, rough-scaled,

– 63 –

terminal joint obliquely ascending. Maxillary palpi moderate, much dilated with dense scales towards apex, obliquely truncate. Forewings with veins 4 and 5 stalked, 8 and 9 stalked out of 7. Hindwings with veins 4 and 5 stalked, 7 out of 6 near origin, anastomosing moderately with 8.

Besides the following species there are three others peculiar to Australia.

Dipl. minima, Butl.

(Cymoriza minima, Butl., “Proc. Zool. Soc.,” 1880, 684; Diplopseustis minima, Meyr., “Trans. Ent. Soc. Lond.,” 1884, 285.)

Male, female.—13–16 mm. Forewings elongate-triangular, apex rounded, hindmargin oblique, with rather deep sinuous indentation above middle, and obtuse bidentate median projection; whitish-ochreous, partially brownish tinged, irrorated with dark fuscous; costa dotted with dark fuscous and white; first line obscure, pale, angulated in middle, posteriorly margined partially with dark fuscous; a black discal dot; second line whitish, anteriorly margined with dark fuscous, from ¾ of costa to ⅘ of inner margin, sinuate-curved outwards above middle; a small double blackish spot on hindmargin in indentation, and two or three dots towards anal angle: cilia ochreous-white, terminal half white, separated by a sharp dark fuscous line. Hindwings grey-whitish, greyer towards apex; a very indistinct pale posterior line; a blackish spot on hindmargin below middle; cilia as in forewings.

Auckland, Wanganui, and Christchurch, from December to March, tolerably common. Also occurs in South-east Australia, Fiji, and Formosa.

Siculodidæ.

For reasons developed elsewhere, I now include this group as a family of Pyralidina.

Siculodes, Hs.
Sic. subfasciata, Walk.

Also from Wellington. I have recorded what I believe to be the same species from Fiji.

Hydrocampidæ.
Paraponyx, Hb.

I have explained elsewhere that Hygraula, Meyr., is to be merged in this genus; the ocelli, though hardly perceptible in some specimens, are in others quite apparent.

Clepsicosma, n. g.

Forehead flat, very oblique. Ocelli present. Tongue well-developed.

– 64 –

Antennæ ¾, in male—? Labial palpi long, straight, porrected, with long loosely projecting scales, attenuated to apex, terminal joint concealed. Maxillary palpi rather long, triangularly dilated with scales, not resting on labial. Posterior tibiæ with outer spurs half inner. Forewings with veins 8 and 9 stalked, 10 closely approximated to 9 towards base, 11 oblique. Hindwings somewhat broader than forewings; veins 3, 4, 5 tolerably approximated at base, 7 from a point with 6, anastomosing with 8 to ⅓; lower median naked, internal area loosely haired.

A singular genus, presenting a combination of characters which encourages the opinion I have latterly entertained, that the Hydrocampidœ and Scopariadœ ought to be united as one family.

Cleps. iridia, n. sp.

Female.—25 mm. Head, antennæ, thorax, and abdomen whitish-ochreous; shoulders rather dark fuscous. Palpi ochreous-fuscous, maxillary paler and ochreous-whitish towards apex. Legs whitish-ochreous, anterior and middle pair rather infuscated. Forewings elongate-triangular, costa moderately arched, apex obtuse, hindmargin obliquely rounded, somewhat waved; whitish-ochreous, sprinkled with brownish-ochreous, towards middle of inner margin suffused with whitish; a streak along basal third of costa irrorated with blackish-fuscous; first line slender, blackish-fuscous, rather irregular, partially interrupted, from ⅓ of costa to ⅖ of inner margin, acutely angulated above middle; a small blackish discal spot; second line slender, white, anteriorly finely margined with blackish, serrate except on sinuation, from before ¾ of costa to ⅔ of inner margin, rather strongly curved, below middle with a very deep sinuation which is at first very narrow and parallel-sided but expands circularly to touch angle of first line and discal spot; a hindmarginal series of small cloudy blackish spots: cilia whitish-ochreous, mixed with whitish, with an interrupted fuscous line. Hindwings white, towards costa slightly ochreous-tinged; a pale ochreousgrey suffusion in disc towards base; a small cloudy grey discal spot, from which proceeds a twice sharply dentate fine dark fuscous line to middle of inner margin; a slender white serrate somewhat curved line from ¾ of costa parallel to hindmargin to middle, becoming prismatic-metallic on two lowest serrations, anteriorly margined finely with blackish, posteriorly margined with a black suffusion opposite metallic portion; space between this line and hindmargin light greyish-ochreous; a dark fuscous line along upper half of hindmargin; cilia ochreous-whitish, with a fuscous line, on lower half of hindmargin wholly whitish.

Auckland (Waitakere Ranges); one specimen, in December.

– 65 –

Scopariadæ.
Scoparia, HW.

Scop. minualis, Walk.

Also from Napier, in December.

Scop. dinodes, Meyr.

Also from Wellington.

Scop. cymatias, Meyr.

Also from Nelson.

Scop. encapna, n. sp.

Male, female.—18–20 mm. Head, palpi, antennæ, thorax, abdomen, and legs dark fuscous; palpi 2, basal joint white; antennæ in male pubescent, ciliations ⅓; legs banded with white, posterior tibiæ irrorated with white. Forewings elongate-triangular, costa almost straight, apex rounded, hindmargin straight, somewhat oblique, rounded beneath; rather dark glossy fuscous, with bronzy reflections, and a few scattered white scales; veins partially irregularly marked with black; first line slender, whitish, indistinct, posteriorly black-margined, indented in middle; orbicular small, suboval, outlined with black, touching first line; claviform small, round, black, detached, conspicuous; reniform 8-shaped, obscurely outlined with darker, separated from second line by a stronger white irroration; second line slender, whitish, anteriorly dark-margined, rather irregularly sinuate; subterminal line slender, whitish, somewhat interrupted, not touching second line: cilia fuscous, with a darker subbasal line, tips obscurely spotted with ochreous-whitish. Hindwings 1 ⅓; fuscous-grey, with a suffused dark fuscous hindmarginal band; cilia light fuscous, with a darker line, tips whitish.

Mount Arthur (3,800 to 4,000 feet), in January; local, but abundant where it occurred, flying wildly over the tops of bushes in the sunshine. In my tabulation of the genus it falls under the same head with the very different S. cymatias, from which, as well as from almost all other species of the genus, it may be immediately distinguished by the very dark hindwings. It may be placed between S. ergatis and S. critica.

Scop. pongalis, Feld.

Also from Auckland, in December.

Scop. colpota, n. sp.

Male, female.—17–18 mm. Head and thorax whitish mixed with fuscous; shoulders dark fuscous. Palpi 2 ½, fuscous, with

– 66 –

an oblique black median band, basal joint white. Antennæ fuscous, ciliations in male ½. Abdomen grey-whitish. Legs dark fuscous, banded with white, posterior pair suffused with white. Forewings elongate-triangular, costa posteriorly gently arched, apex obtuse, hindmargin oblique, slightly rounded; basal ⅗ ochreous-brown, terminated by a straight line from ⅗ of costa to ⅗ of inner margin, terminal ⅖ light-grey; a thick very oblique black streak from base of costa to ¼ of disc; first line thick, black, almost straight, preceded by a white irroration; orbicular and claviform obsolete; space between ochreous-brown colour and second line suffused with white; reniform 8-shaped, faintly outlined with grey; second line slender, whitish, anteriorly margined with grey, sinuations indented, central portion strongly curved; subterminal cloudy, whitish, interrupted and touching second line in middle; an interrupted white hind-marginal line: cilia ochreous-whitish, with a grey subbasal line. Hindwings 1 ⅓, very pale whitish-grey, postmedian line and hindmargin suffusedly darker grey; cilia whitish, with a grey line.

Wellington; three specimens in January. Closely allied to S. periphanes, and very similar; best distinguished by the form of the second line, which has both sinuations rather strongly marked and indented, and the median portion rather strongly curved, whilst in S. periphanes the upper sinuation is very slight, the lower imperceptible, and the median portion very slightly curved; in S. colpota the first line is less oblique, and not distinctly white as in S. periphanes.

Scop. periphanes, Meyr.

Also from Whangarei, in December.

Scop. psammitis, Meyr.

Also from Mount Arthur (4,000 feet).

Scop. epicomia, Meyr.

Also from Auckland and Nelson (to 3,800 feet), in December.

Scop. axena, Meyr.

Also from Mount Arthur (4,000 to 4,500 feet).

Scop. exilis, Knaggs.

Also from Wellington, in January.

Scop. deltophora, Meyr.

Also from Mount Arthur (4,500 feet).

Scop. trivirgata, Feld.

Also from Mount Arthur (3,800 feet), in January.

– 67 –

Xeroscopa, Meyr.

Xer. astragalota, Meyr.

Also from Mount Arthur (4,000 feet).

Xer. niphospora, Meyr.

Also from Mount Arthur (4,000 to 4,500 feet).

Xer. nomeutis, Meyr.

Also from Mount Arthur (4,000 feet).

Crambidæ.
Orocrambus, Meyr.

I have explained elsewhere that, as in some individuals of O. melampetrus, vein 8 of the hindwings is free, whilst in others it anastomoses with vein 7 in the usual way, this character cannot be used to define the genus; but that the genus is, notwithstanding, good and tenable if the distinction from Crambus is made to consist in the densely hairy undersurface of the thorax and coxæ. As thus defined, the genus will include O. melampetrus, Meyr.; O. catacaustus, Meyr., O. tritonellus, Meyr. (the two latter having been formerly placed in Crambus), and the following new species.

Or. mylites, n. sp.

Male, female.—23–25 mm. Head whitish-ochreous, fuscous on sides. Palpi 3 ½, whitish-ochreous, apex mixed with blackish. Antennæ dark fuscous, ciliations in male ¼. Thorax ochreous-fuscous, shoulders and a suffused longitudinal dorsal streak ochreous-whitish. Abdomen grey, posteriorly irrorated with ochreous-whitish, anal tuft mixed with yellow-ochreous. Legs dark grey, suffusedly irrorated with whitish-ochreous. Forewings elongate, posteriorly gradually dilated, costa hardly arched, apex obtuse, hindmargin obliquely rounded; bronzy-fuscous, more or less ochreous-tinged; a moderate straight white central longitudinal streak, irregularly irrorated with fuscous-grey, from base to hindmargin, margined above with dark fuscous from before middle to near hindmargin, and beneath by a dark fuscous attenuated streak from near base which diverges in middle and runs to hindmargin above anal angle, often accompanied at divergence by a few white scales; a white irroration towards costa about ¾; a narrow white irroration along inner margin from base to anal angle, towards base margined above with dark fuscous: cilia glossy light grey. Hindwings grey; hindmargin suffusedly darker; cilia light grey, tips whitish.

Mount Arthur (4,000 to 4,800 feet), in January; common, frequenting swampy places. Nearest to O. catacaustus, but easily distinguishable by the whitish dorsal streak of thorax, and the grey irroration of the white median streak of forewings.

– 68 –

Or. catacaustus, Meyr.

Also from Mount Arthur (4,500 feet).

Crambus, F.

Cr. heliotes, n. sp.

Male, female.—15–18 mm. Head, palpi, antennæ, thorax, abdomen, and legs rather dark fuscous; palpi 3 ½; antennal ciliations in male ½; thorax sometimes with a slender ochreous-whitish dorsal streak indicated; posterior tibiæ suffused with whitish-ochreous. Forewings elongate, posteriorly moderately dilated, costa hardly arched, apex obtuse, hindmargin rather obliquely rounded; ochreous-brown; sometimes a few scattered black scales, sometimes a black suffusion forming strong longitudinal streaks in disc and along veins towards anal angle; sometimes an ochreous-whitish streak along submedian fold from base almost to anal angle, and a similar longitudinal streak above middle from middle of disc to near hindmargin; all these markings often quite absent: cilia glossy whitish-grey. Hindwings bright orange; base, costa, and inner margin, sometimes also hindmargin and parts of one or two veins, slenderly suffused with dark fuscous; cilia whitish-fuscous, with a cloudy darker line.

Mount Arthur (3,800 feet), in January; common in a restricted locality in one of the limestone valleys. It varies considerably, but is the only known Crambus with orange hindwings.

Cr. dicrenellus, Meyr.

Also from Mount Arthur (4,000 feet).

Cr. isochytus, n. sp.

Male.—34–40 mm. Head white, sides behind eyes pale ochreous. Palpi 5, light brownish-ochreous, white above and towards base beneath. Antennæ grey, flatly dentate, ciliations ⅔. Thorax pale brownish-ochreous, with a broad white dorsal stripe. Abdomen ochreous-whitish. Legs ochreous-fuscous, posterior pair ochreous-whitish. Forewings elongate, posteriorly gradually dilated, costa slightly arched, apex round-pointed, hindmargin somewhat sinuate, oblique; pale glossy brownish-ochreous, with a slight brassy tinge; a narrow white costal streak from base, rather dilated beyond middle, then attenuated to a point, terminating before apex; a moderate straight white central longitudinal streak from base to hindmargin; a moderate white streak, sometimes indistinct, attenuated at both extremities, along inner margin from base to anal angle, leaving a marginal line of ground-colour on posterior ⅔: cilia snow-white. Hindwings grey-whitish or ochreous-whitish; cilia white.

– 69 –

Mount Arthur (4,500 feet), in January; three specimens. One of the largest species of the genus; most like C. dicrenellus, but considerably larger, and distinguished by the costal streak not reaching apex, and the dorsal streak not being marginal posteriorly.

Cr. crenœus, Meyr.

Also from Mount Arthur (4,000 feet).

Cr. flexuosellus, Dbld.

Also from Whangarei, Napier, and Nelson (to 4,000 feet).

Cr. harpophorus, Meyr.

Also from Mount Arthur (4,000 feet).

Thinasotia, Hein.

The genus formerly called by me Thinasotia I have since characterised as a distinct genus under the name of Hednota; but the following species, differing both from Crambus and Hednota, I think may remain here for the present.

Thin. claviferella, Walk.

(Aquita claviferella Walk., Suppl., 1765; Aphomia strígosa, Butl., Proc. Zool. Soc., Lond., 1877, 398, pl. xliii., 10; Crambus strigosus, Meyr., “Trans. N.Z. Inst.,” 1882, 31.)

I have recently made this synonymic correction; Walker's type is unset, which probably led to my passing it over. The species occurs also in Tasmania and Victoria, and is therefore specially interesting.

Tauroscopa, n. g.

Forehead vertical; ocelli present; tongue well-developed. Antennæ ¾, in male filiform, minutely ciliated, basal joint with a small tuft of hairs. Labial palpi moderately long, porrected, clothed beneath with very long dense projecting hairs, terminal joint concealed. Maxillary palpi rather long, dilated with long rough hairs. Thorax and coxæ clothed with dense rough hairs beneath. Forewings with veins 8 and 9 stalked. Hindwings with veins 4 and 5 stalked, 6 remote from 7 at origin, 7 anastomosing shortly with 8.

Closely allied to Hednota, from which it differs essentially only by the densely hairy undersurface of thorax and coxæ; it therefore stands in exactly the same relation to Hednota as Orocrambus to Crambus.

Taur. gorgopis, n. sp.

Male.—22 mm. Head, palpi, and thorax grey, densely mixed with black. Antennæ and abdomen blackish-grey. Legs blackish-grey, apex of joints ochreous-whitish. Forewings rather elongate-triangular, costa hardly arched, apex obtuse,

– 70 –

hindmargin rather obliquely rounded; grey, densely irrorated with black; a black dentate line near base, preceded and followed by a white irroration; lines whitish, dentate, margined with black; first from ⅓ of costa to before middle of inner margin, preceded by a blackish band, and followed by a whitish irroration; second from ⅘ of costa to ¾ of inner margin, rather curved, indented beneath costa, preceded by a white suffused irroration on upper half: cilia grey, irrorated with black on basal half. Hindwings and cilia dark fuscous grey.

Mount Arthur (4,000 feet); one specimen, in January.

Diptychophora, Z.

Dipt. chrysochyta, Meyr.

Also from Whangarei, in December.

Dipt. metallifera, Butl.

Male, female.—17–20 mm. Head white, collar ochreous-yellow. Palpi externally yellow-ochreous, suffused with grey towards margins, internally white. Antennæ white. Thorax ochreous-yellow, shoulders fuscous. Abdomen whitish. Legs white, anterior tibiæ, first joint of tarsi, and apex of three terminal joints dark fuscous. Forewings triangular, costa slightly arched, apex rounded, hindmargin oblique, slightly rounded, twice sinuate-indented on upper half; ochreous-orange, somewhat deeper posteriorly; a narrow rather dark fuscous streak along costa; lines fuscous, partially indistinct; first from ⅓ of costa to before middle of inner margin, sharply angulated above middle, rather sinuate and more strongly marked beneath; second from ⅔ of costa to ⅔ of inner margin, preceded and followed by white spots on costa, strongly curved outwards above middle, sinuate beneath; a narrow-transverse inwards-curved leaden-grey-metallic discal spot; between this and hindmargin are four parallel longitudinal leaden-grey-metallic streaks, not reaching discal spot, first terminating in a white dot before apex, second and fourth touching hindmargin; two very short slender longitudinal leaden-grey-metallic marks on second line below middle; three black dots on hindmargin below middle, central subquadrate: cilia shining light-grey, with snow-white subapical, median, and supra-anal patches, and a strong blackish-grey basal line. Hindwings ochreous-white, apex more ochreous-tinged, and with a small faint greyish ante-apical spot; cilia white.

Auckland, Wellington and Nelson, in December and January; several specimens.

Dipt. selenœa, Meyr.

Also from Whangarei and Auckland, in December.

Dipt. auriscriptella, Walk.

Also from Whangarei, Auckland, and Napier, in December.

– 71 –

Dipt. harmonica, n. sp.

Male.—12–13 mm. Head white. Palpi white, externally ochreous-tinged, towards apex slightly infuscated. Antennæ whitish. Thorax white, with a few fuscous scales. Abdomen light grey. Legs white. Forewings triangular, costa slightly arched, apex obtuse, hindmargin oblique, twice sinuate-indented on upper half; white, suffused with pale ochreous-greyish except towards inner margin; lines very slender, dark fuscous, thickened at extremities; first from beyond ¼ of costa to middle of inner margin, strongly curved, nearly preceded on costa by a small dark fuscous oblique mark, and on lower half by a wedge-shaped dark fuscous streak from inner margin; a transverse leaden-grey-metallic discal spot, lower extremity becoming obscurely whitish-ochreous; a small dark fuscous spot on costa above this; second line from ⅔ of costa to ¾ of inner margin, very strongly curved outwards on upper ⅔, below this slightly sinuate, margined on costa with white wedge-shaped streaks, on lower half followed by a fainter similar line enclosing a white line; a yellow-ochreous space extending from discal spot to hindmargin, interrupting second line, cut by three parallel longitudinal leaden-grey-metallic purplish-tinged streaks, not reaching discal spot, upper alone reaching hindmargin; a white almost apical oblique mark from costa, separated from white margin of second line by a fuscous suffusion; space between lower half of second line and hindmargin, yellow-ochreous, suffusedly irrorated with dark fuscous; three black dots on hindmargin below middle, central subquadrate: cilia shining metallic bronzy-grey, with a strong black basal line. Hindwings grey; cilia whitish, with a grey basal line, and a faint cloudy grey median shade.

Auckland (Waitakere Ranges), in December; two specimens.

Dipt. epiphœ, Meyr.

Also from Mount Arthur (3,800 feet).

Dipt. elaina, Meyr.

Also from Auckland, Napier, and Nelson.

Phycitidæ.

Maxillary palpi not triangularly dilated. Forewings with vein 7 absent, 8 and 9 stalked. Hindwings with lower median pectinated.

Although I am now able to quote species of this and the following families as occurring in New Zealand, they are not to be regarded as forming any part of the truly indigenous fauna.

Crocydopora, Meyr.

Antennæ of male shortly ciliated, with a sinuation above basal joint containing a large tuft of scales. Labial palpi rather

– 72 –

long, porrected, second joint thickened with dense appressed scales, terminal joint short. Maxillary palpi obsolete. Forewings with veins 3 and 4 approximated at base, 5 absent, 7 absent, 8 and 9 stalked. Hindwings with vein 2 almost from angle of cell, 3 and 4 stalked, 5 absent, 6 and 7 stalked, 8 closely approximated to 7 beyond 6 but not Anastomosing.

Nearly allied to the cosmopolitan Anerastia; only one species known.

Croc. cinigerella, Walk.

(Nephopteryx cinigerella, Walk., Supp., 1719; N. stenopterella, Meyr., “Proc. Linn. Soc. N.S.W.,” 1878, 200.)

Male, female.—16–20 mm. Forewings very elongate, narrow, slightly dilated; dark grey, finely irrorated with whitish; lines indistinct, indicated by serrate dark margins; first at ⅓, somewhat oblique, preceded on inner margin by a pale grey-reddish spot margined with dark fuscous; second at ⅘, indented above middle; a pale grey-reddish suffusion towards middle of inner margin; two black dots placed transversely in disc beyond middle. Hindwings grey.

Whangarei and Nelson, in December and January; several specimens. This species is very common in East and South Australia, frequenting dry, usually sandy, places, and coming freely to lamps. I have long been familiar with it there, but never took it in New Zealand until the summer of 1885–86, nor have I seen it in other collections; it is therefore possible that it may be a recent accidental introduction; if so, it will probably be found soon to become more common and generally distributed. But in any case it is to be considered as a strictly Australian insect, which has incidentally found its way to this country.

Homœosoma, Curt.

I have two specimens of a species closely approaching and perhaps identical with the Australian H. vagella, but as they are both females, and differ slightly, I think it necessary to wait for further evidence before pronouncing on their identity. H. vagella has similar habits to the preceding species, and a still wider range; it might therefore very well occur.

Galleriadæ.

Maxillary palpi very small, filiform. Forewings with vein 7 stalked with 8 and 9. Hindwings with vein 8 anastomosing with 7, lower median pectinated.

Achrœa, Hb.

Antennæ of male filiform, simple, basal joint with a triangular projection of scales. Labial palpi very short, in male subascending, in female porrected. Maxillary palpi very

– 73 –

short, obtuse. Forewings with veins 4 and 5 in male separate, in female stalked, 8 and 9 out of 7, 10 absent. Hindwings with veins 3 and 4 stalked, 5 absent, 7 out of 6 near origin, anastomosing with 8 to beyond middle.

Achr. grisella, F.

Male, female.—16–25 mm. Head light ochreous - yellow. Forewings elongate, not dilated, costa moderately arched, apex rounded; light fuscous, unicolorous. Hindwings tolerably pointed, light grey.

Nelson, in January; one specimen. A common European species, introduced into Australia and New Zealand by civilisation; the larva feeds on the wax in beehives (often proving extremely destructive), and also on dried fruits.
