Capua intractana (Walk.), Char. Het., p. 83 (1869).
This Australian species must now be placed on the New Zealand list. During February and March, 1923, nine or ten of each sex were taken at light. The species is small and obscure, but (owing to its habit of coming to light) it is hardly likely to have been passed over if it had previously occurred in any numbers. In Australia C. intractana is widely distributed, being found in Queensland, New South Wales, Victoria, and South Australia. A short description is appended, which may assist New Zealand lepidopterists to recognize the species.
♂, 11–13 mm.; ♀, 14–17 mm. Forewings rather broad, costa strongly arched, termen straight, oblique; dull brown mixed with ochreous, especially in female; costal patch in male small, ochreous, confined to costal half and frequently obsolete; in female dark brown, margin obliquely outwards to above middle, thence angled sharply inwards; following this is an ochreous fascia, dilated dorsally, usually absent in male; a sub-terminal ochreous fascia, triangularly dilated, on upper half. The markings are often indistinct and frequently absent. Hindwings fuscous-grey with paler mottling.
Epichorista abdita n. sp. (Fig. 2, D and E.)
♂. 11 ½–13 mm. Head, palpi, and thorax bright reddish - ochreous. Antennae in male ciliated, 1 ½. Abdomen dark fuscous. Legs ochreous-whitish, tarsal segments annulated with fuscous. Forewings, costa strongly arched at base, apex rectangular, termen very slightly oblique, rounded beneath; bright ochreous-reddish; markings very obscure; five or six fuscous dots on basal half of costa; traces of some leaden-white fasciae at ⅓ apical half of wing with numerous obscure waved leaden-white
fasciae, visible only under magnification; central fascia indicated by a clear reddish area on costa at middle: fringes ochreous-reddish, tips paler. Hindwings dark fuscous: fringes greyish-fuscous, with basal band and the tips round termen tinged with ochreous.
In one example the markings are quite obsolete and the ground-colour is much paler.

Superficially very like some varieties of E. emphanes (Meyr.), but a smaller and duller species; the longer antennal ciliations form a good distinguishing structural character.
