Hydriomenidae.

Tatosoma monoviridisata n. sp.

♂ ♀. 31–32 mm. Head and thorax olive-green. Antennae: proximal third olive-green, tips brownish. Palpi nearly 3 mm. Abdomen varying green above, irrorated with dark-brown scales with lateral dorsal tufts of brown-grey hairs at each segment, especially noticeable on fourth, fifth, sixth, and terminal segments. Forewings olive-green, elongate, costa rounded, hind-margin obliquely rounded, several transverse wavy dentate darker-greenish stripes, convex externally near middle, the most conspicuous being at ⅙, before ½, and at ⅔; a series of double dots around termen. Hindwings in ♀ small, elongate, grey, tinged with greenish terminally; an indistinct greenish band at ⅔; lobe of hindwings in ♀ 3mm. long; all cilia light green.

The palpi of this species are shorter than in T.tipulata, but the lobe of the hindwing is as small as in tipulata

Twelve specimens were beaten from Coriaria on the Waitati Water Reserve in October and November, 1918, and three in 1919.

Micropterygidae.

Sabatinca lucilia n. sp.

12 mm. Head, face, and palpi covered with long bronze-brown hair. Antennae purplish tending to brown at tips. Thorax brown, densely covered with long brown hair. Abdomen grey-blackish along sides. Legs ochreous tinged with grey-blackish. Forewings ovate-lanceolate, costa bent abruptly near base, arched, apex less acute than in incongruella; basal area to nearly ⅓ ochreous suffused with ruby banded by abrupt black transverse line; an ochreous-grey band slightly suffused with ruby reaching to nearly ½ widening on dorsum; a dark fascia bordered blackish-grey, constricted both sides at middle and narrowed on anal margin; at ⅔ another light-grey band slightly tinged with orange but broken in centre by longitudinal blackish stripe; a transverse blackish-bordered ochreous band, beyond which to apex light grey slightly tinged with orange; cilia ochreous with dark-greyish-brown bars in continuation of the dark markings on the wings. Hindwings dark grey suffused with violet, brighter towards apex; cilia dark grey with a few orange hairs.

My first specimen, rather worn, I took at the electric light at Waitomo Hotel on the 25th December, 1916. During the second week of January, 1919, I took six specimens in good condition on a sunny moss-covered clay, bank at Kauri Gully, Auckland. The season was an exceptionally late one, and normally the species would probably be at its best quite a month earlier,
