Tortrix melanosperma n. sp.
♂ 21 mm. Head, palpi, and thorax light grey, palpi moderate, ascending. Antennal ciliations 1. Abdomen pale ochreous-grey, anal tuft ochreous-whitish. Forewings elongate, costa moderately arched, without fold, apex tolerably pointed, termen nearly straight, rather strongly oblique, pale grey, with scattered black scales tending to form rows; costa rather broadly suffused with whitish, a conspicuous black dot m disc at ¾: cilia whitish-grey. Hindwings light grey: cilia whitish-grey.
Arthur's Pass, 3,000 ft, m December (Hudson); one specimen. Allied to indigestana.
Harmologa trisulca n. sp.
♂ 29–31 mm. Head, palpi, and thorax with ferruginous hairs, beneath these dark fuscous, palpi 3. Antennae without ciliations. Abdomen dark fuscous, segments margined with grey-whitish scales, anal tuft grey-whitish. Forewings elongate, moderate, posteriorily dilated, costa gently arched, with narrow fold on basal sixth, apex obtuse, termen straight, little oblique, rounded beneath, deep ochreous-yellow; a broad pale ochreous-yellowish median streak from base to ⅘, suffused beneath and posteriorly, sharply defined above, costal area above this wholly deep red-brown, costal edge suffused with dark leaden-grey, dorsal third of wing suffused with ferruginous: cilia light leaden-grey, basal third with yellowish scales, tips whitish Hindwings dark grey, towards apex and termen blackish-tinged. cilia grey-whitish, basal third grey.
♀ 33 m. Head and palpi pale ochreous, palpi 4. Thorax with pale-ochreous hairs, blackish-scaled beneath. Abdomen whitish-ochreous Forewings elongate, moderate, slightly dilated, costa gently arched, apex obtuse, termen faintly sinuate, little oblique, pale ochreous-yellowish; two dark-fuscous dots in disc before and beyond middle, just below upper margin of cell. cilia whitish, basal third pale-yellowish. Hindwings pale whitish-yellowish sprinkled with grey, dorsal ⅖ suffused with grey: cilia yellow-whitish.
Arthur's Pass, 3,500 ft., m December (Hudson), four specimens. The ♂ is much like siraea, but a larger and finer insect, more brightly coloured, the costal area of forewings very much darker than dorsal, the head and thorax without grey suffusion, whilst in siraea the costal and dorsal areas are nearly the same in colour, the costal edge distinctly whitish, and the median streak forms a distinct projection along fold; the ♀, however, are entirely different, siraea having grey-whitish forewings and white hindwings, whilst this species is much more like aenea. A ♂ sent by Mr Hudson from the Hunter Mountains is true siraea.
Harmologa lychnophanes n. sp.
♂. 28 mm. Head dark fuscous, with some ferruginous hairs. Palpi 3, dark fuscous mixed with brownish. Antennae minutelv ciliated. Thorax dark fuscous, with ferruginous hairs. Abdomen dark fuscous, segments margined with whitish-yellowish scales, anal tuft pale ochreous-yellowish mixed with fuscous. Forewings elongate, moderate, posteriorly somewhat dilated, costa gently arched, with moderate fold extending from base nearly to ¼, apex rounded-obtuse, termen slightly rounded, hardly oblique; ochreous-yellowish, somewhat paler in middle longitudinally, dorsal area deeper, with a ferruginous-brown dorsal streak from ¼ to near tornus; costal third bright deep ferruginous, along costa rather broadly and irregularly deep leaden-grey: cilia pale ochreous with grey median shade, towards base ferruginous-yellow. Hindwings ochreous-yellowish sprinkled with grey, becoming yellowish-ferruginous towards apex and termen, base somewhat suffused irregularly with light grey: cilia pale-yellowish, basal third ferruginous-yellow.
Mount Arthur, 4,500 ft, in January (Hudson); one specimen. Formerly identified by me incorrectly as siraea, of which my series was taken by myself in the same locality (broadly speaking); I now see that it must be regarded as quite distinct. There is evidently a not inconsiderable group of allied species, and other mountains should be searched for them. As the sexes are always very dissimilar, both should be obtained from the same locality if possible.
