towards base, especially round apex. Hindwings whitish, faintly yellowishtinged posteriorly, and spotted with grey; cilia whitish, with a grey basal line.
Remote from all its congeners in superficial appearance; the peculiar angulated subcostal mark at base, (differing in the sexes), is unique in its way, but only conspicuous in the male.
Common at Christchurch, Wellington, and Dunedin, generally in gardens, in January, February, March, and August.
7. Cacoecia, Hb.
Thorax smooth. Antennæ in male ciliated. Palpi moderate or rather long, porrected, second joint triangularly scaled. Forewings in male with strong costal fold. Hindwings broader than forewings. Forewings with 12 veins, 7 and 8 separate, 7 to hindmargin. Hindwings with 8 veins, 3 and 4 from a point, 5 approximated at base to 4, 6 and 7 separate (rarely stalked).
Distinguished from Harmologa by the origin of veins 3 and 4 of the hindwings from the same point, from Tortrix by the costal fold of male. Of the species which I originally referred here, four have been satisfactorily determined to be mere varieties, three have been transferred to the neighbouring Harmologa, one (of which the male had been unknown) to Tortrix, and one is removed to the Grapholithidæ, the basal pectination of the hindwings having been overlooked. I have now only two true species of Cacoecia from New Zealand; the genus is numerously represented in Australia.

Male, female.—19–28 mm. Head and thorax varying from ochreous to dark fuscous or purple-fuscous (sometimes discolorous); palpi rather long. Forewings moderately broad, posteriorly dilated, less in female, costa moderately arched, in female straighter posteriorly, hindmargin sinuate, not oblique; varying from ochreous to dark ochreous-fuscous, finely strigulated with darker, sometimes wholly suffused with purple; markings very ill-defined, hardly darker than ground-colour, often wholly obsolete; outer
