New Species of Lepidoptera.

[Read before the Otago Institute, 9th December, 1924; received by Editor, 31st December, 1924; issued separately, 10th April, 1926.]

Hydriomenidae.

Xanthorhoe ida n. sp.

♂. 24 mm. Head, palpi, and thorax grey-fuscous. Antennae fuscous, pectinations 6. Abdomen grey-fuscous. Forewings elongate-triangular, costa outwardly rounded, apex bluntly pointed, termen slightly sinuate, oblique; brown-ocherous with admixture of reddish, lines white; an irregular wide transverse band at ¼, outwardly convex in middle, slightly reddish with narrow white edges on either side; at ¾ a transverse dentate white line with largest dentations outwardly about middle; reddish beyond this and then darkening into brown-ochreous towards termen; a blackish discal dot; subterminal line dentate, white, inwardly edged with dark brown: cilia dark fuscous. Hindwings dark grey-ochreous on inner half, externally lighter ochreous, crenulate markings along termen: cilia dark fuscous.

Seven specimens, the first being taken by Mr. W. G. Howes, F.E.S., at the Eweburn Stream, near Mount Ida, Otago Central, in February, 1923.

Hydriomena callichlora harmonica n. subsp.

♂. 31 mm. Head, palpi, thorax, and abdomen orange mixed with grey. Forewings bright orange and pale cerulean blue in many wavy bands bordered in places with blackish; before middle a wide dentate orange band, centrally blue and with blackish edges; at ⅔ a blackish band with bidentate projection in middle; beyond this orange and blue crossed by wavy blackish lines; a bright-orange area posteriorly, crossed by another band of blue; and a row of small black dots along termen. Hindwings moderate, hind-margin rounded, crenate; grey-whitish with several indistinct grey lines across outer half.

Waitati Bush, near Dunedin, in November, 1917.

This beautiful and unique specimen is so different from my other examples, of which I have a good series from various localities, that it seems at first glance to be a new species. However, no structural difference has been noted in it from typical examples of callichlora.

Crambidae.

Crambus corylana n. sp.

♂. 36 mm. Head grey-white. Palpi white above and internally, ochreous externally. Antennae fuscous. Thorax white; patagia ochreous. Abdomen grey-whitish. Anterior legs light fuscous, posterior pair light ochreous. Forewings long, somewhat dilated posteriorly, costa slightly arched, apex bluntly pointed, termen slightly sinuate, oblique; grey-white, extreme costal edge fuscous widening at about ¾ where it is ochreous; a broad ochreous stripe from base below middle to termen above tornus and extending across to dorsum from about ⅓ to tornus: cilia white, ochreous near dorsum. Hindwings pale ochreous-grey: cilia ochreous-grey.

Very close to C. ephorus but less bright. May be distinguished by the wide ochreous stripe extending transversely to dorsum along outer ⅔. A good series in February, 1923, at the base of Mount Ida, Otago Central.

Fore legs black annulated with grey-white at joints, hind legs grey-whitish with blackish annulations on tarsi. Forewings moderate, triangular, costa posteriorly moderately arched, apex obtuse, termen slightly rounded, oblique; white and light ochreous vividly marked with black; a small whitish mark at base bordered by a black transverse band widening on inner margin, followed by a broader white transverse band indented at middle and dotted by some black scales which tend to form two obscure dots; a black transverse band from ⅓ of costa, broken and rather diffused towards dorsum, often connected along costa at ⅔ with a black transverse mark extending nearly half-way across wing, surrounded by a large area of whitish often slightly ochreous outwardly and towards dorsum; a black dot near costa at ¾, and a wide terminal band of black with an obscure whitish sub-terminal line: cilia blackish with narrow black subbasal line. Hindwings grey-ochreous merging into blackish outwardly; disc with a black dot sometimes comma-shaped: cilia blackish with black subbasal shade.

About twelve specimens taken during as many visits to the Waitati Hills and Mount Maungatua, 2,000 ft., in November, during three seasons.
