Art. XVI.—New Lepidoptera
[Read before the Otdgo Institue, 1st August, 1916, received by Editors, 30th December, 1916, issued separately, 16th August, 1917.]
Adeixis parvitis n. sp.
One specimen. Expanse 16 mm. Face and head milk-white Palpi elongate. Thorax white Forewings grey-white faintly irrorated with brown; a distinct brown band across wing at ⅔, edged outwardly with white; faint brown irrorations follow, deepening towards termen, which is quite brown, especially at the apex: cilia long, grey, with a shorter row of brown cilia at base. Hindwings grey-white, deepening to grey at termen: cilia white.
This small but well-defined species is the second of the genus to be found in New Zealand, and, like the other species (A inostentata), this may prove to be Australian also. The single specimen was taken by Mr. C. Clarke at Broad Bay, 18th December, 1915.
Xanthorhoe subflava n. sp.
Five specimens, all ♂ Expanse, 38–39 mm. Face and head reddish-ochreous. Antennae ochreous with brown pectinations well developed. Thorax uniform bright ochreous. Abdomen bright ochreous with two grey marks dorsally at the base of each segment. Wings ochreous faintly stippled with grey-brown; an indistinct line at base followed by an indistinct line at ⅓ a very faint grey line at ½, a better-defined but still faint line at ⅔, followed by a paler area forming a band across the wing; subterminal line appears as a series of irregular somewhat crescentic marks between the veins; clavifórm almost obsolete, reniform appears as a slight dark-brown mark distinct, but little more than a dot. Hindwings pale ochreous, clouded on termen with pale grey between veins; underside pale ochreous, with lunule appearing as a well-defined dot.
This fine moth resembles in coloration and markings X. aegrota, but is one-third larger in size, and the underside is free from marking.
Seven specimens showing considerable variation in the extent of markings on the forewings were taken by myself at 4,000 ft. level, in the neighbourhood of Arthur's Pass, 1st February, 1915.
Chloroclystis clarkei n. sp.
♀ 25 mm. Head and appendages, thorax, and abdomen grey-brown. Forewings dark grey-brown, with the veins distinctly shown by being irrorated with black and grey to ⅔ across wing, and from there to termen irrorated with yellow and black; a black line edges costa, interrupted by two white marks at ⅓, followed by three white marks at ½, two white marks at ¾, another close to apex: these marks all rather indistinct. Termen distinctly edged with a thin black line, interrupted by yellow dots at the ends of the veins. Hindwings grey suffused with darker grey, and with a rather indistinct series of transverse irregular lines; termen distinctly edged with a thin dark line, small yellow dots interrupting it on the veins: cilia light grey with a dark-grey line at base.
Taken on Flagstaff Hill, Dunedin, in March, 1915, by Mr. C. Clarke, whose keen steady work is worthy of appreciation.
