Tortricidae.

Capua arcuata sp. nov.

♀. 15–16 mm. Head, palpi, antennae, and thorax ochreous-whitish sprinkled with reddish. Abdomen ochreous-grey. Forewings oblong, termen sinuate, dorsum straight; whitish, irregularly mixed with pale ochreous; fasciae reddish-ochreous, becoming blackish on margins; basal patch indicated by obscure irregular fascia, almost obsolete on costa and dorsum; median fascia broad, from costa at ⅓ outwardly oblique to below middle, thence bent upwards again to costa at ¾ enclosing semi-oval area much mixed with white; one or two costal blotches of reddish-black within this enclosed area; a broad fascia from tornus, parallel to termen and touching median fascia at apex; a narrow white interrupted space between these fasciae; two or three irregular white blotches on costa near apex and a series of obscure dark strigulae along dorsum: cilia white mixed with reddish-brown. Hindwings whitish-grey, suffused and spotted with pale fuscous: cilia greyish-white with a darker basal line.

Distinguished from Capua plinthoglypta Meyr. by the shape of the basal patch and the deeper and narrower pale median costal space.

Invercargill, in January. Two specimens.

Eurythecta trimaculata sp. nov.

♂ ♀. 9 ½–11 mm. Head and palpi grey. Thorax grey, with a posterior curved black band sometimes interrupted at middle. Abdomen dark grey. Forewings moderate, costa slightly arched at base, straight, apex obtuse, termen faintly rounded, oblique; whitish-grey, irrorated with black;

markings black or dark fuscous with bronzy reflections; some spots and strigulations near base; a broad inwardly oblique fascia at ⅓, often interrupted or obscure on upper half; three equidistant triangular dots on costa between ⅓ and apex; a broad irregular fascia from tornus, its apex sometimes touching central costal dot; a terminal suffusion beneath apex, sometimes extending to near tornus: cilia usually grey with a darker line, sometimes wholly greyish-fuscous. Hindwings fuscous-grey, darker round apex: cilia fuscous-grey with a darker line, tips paler.

Near Eurythecta robusta Butl., but in that species the fascia are outwardly oblique.

Queenstown, in December, on open hillsides from 1,000 ft. to 2,500 ft.

Harmologa sanguinea sp. nov.

♂. 17–18 ½ mm. Head fuscous mixed with grey. Palpi reddish-brown. Antennae fuscous ringed with ochreous, ciliations 1 ½. Thorax brownish-red mixed with grey. Abdomen pale fuscous, segmental margins grey. Forewings elongate, costa moderately arched, apex subacute, termen rounded, slightly oblique; dark purplish-red; margin of basal patch oblique, almost straight, from ⅕ to ⅓; followed by a shining silvery fascia much intermixed with yellow or orange, its outer margin from just beyond costal patch, very oblique to ¾, thence less oblique to dorsum at ½; a similarly coloured median fascia, rather broad, narrowest on costa, usually becoming obsolete at middle; a similar fascia from tornus, rather oblique inwardly to middle, thence bent acutely downwards and inwards, sometimes obscurely touching median fascia; an obscure subterminal fascia from before apex obliquely to termen at middle: cilia greyish-fuscous mixed with some reddish and with two darker lines. Hindwings dark fuscous: cilia grey with a darker line.

Easily distinguished from the following form by the differences in the tornal and subterminal fasciae.

Mount Cleughearn, Hunter Mountains, in January. Five males amongst Veronica and Cassinia bushes, at an elevation of about 3,000 ft.

Harmologa festiva sp. nov.

♂. 16 mm. Head grey. Palpi ferruginous. Antennae fuscous, obscurely ringed with paler, ciliations 1. Thorax fuscous mixed with ochreous-reddish and grey. Abdomen fuscous, segmental divisions grey. Forewings moderate, rather oblong, costa strongly arched, apex obtuse, termen bowed, hardly oblique; bright ochreous-red; fasciae white; first fascia, defining basal patch, outwardly oblique, almost straight, narrowest towards costa, its edges suffusedly margined with blackish, clouded above and below middle with ochreous, median fascia broad, dilated in disc, lower half almost filled with ochreous blotch; subterminal fascia straight, blackish-margined, from ⅚ costa to tornus: cilia pale ochreous with darker basal line. Hindwings fuscous: cilia as in forewings but paler.

A shorter-winged species than the preceding; the antennal ciliations are also shorter.

Hunter Mountains, in January. Four males taken amongst Veronica and other shrubs, at about 3,000 ft.

Harmologa reticularis sp. nov.

♂. 16 ½–17 ½ mm Head greyish-fuscous. Palpi dark brownish-ochreous. Antennae fuscous ringed with whitish, ciliations 1 ¼. Thorax fuscous mixed with orange and white. Abdomen fuscous-grey. Forewings rather

elongate, costa moderately arched, apex rounded, termen obliquely rounded; pale orange; some irregular leaden-coloured markings within basal patch; first fascia narrow, outwardly oblique, bifid from middle to dorsum, white; median fascia narrow, outwardly oblique, irregular, costal portion white and the lower half breaking up into a network of leaden-coloured fasciae; a narrow fascia from ¾ costa, bifid from middle, anterior limb to ¾ dorsum and posterior limb to tornus, white, leaden-coloured beneath costa and on anterior limb; a white dot, margined beneath with leaden colour, on costa between this fascia and the preceding one; a narrow white subterminal striga, touching termen before tornus: cilia grey mixed with white, tips yellowish. Hindwings greyish-fuscous: cilia greyish-white with darker basal line.

Allied to the two preceding forms, but abundantly distinct in colour and markings. In one specimen the markings are almost wholly leadencoloured.

Longwood Range, in December. Two males on the bare tops, at about 2,800 ft.
