central longitudinal silvery-white streak from base to hindmargin, rather narrower towards base, lower edge slightly indented beyond middle; faint indications of whitish lines on veins towards hindmargin; a whitish suffusion along inner margin from base to anal angle, very narrow at base, posteriorly indistinct or obsolete: cilia white. Hindwings whitish-grey, towards apex and hindmargin fuscous-grey; cilia white. A distinct species, immediately known by the dark brown ground-colour, and narrow silvery-white costal streak extending from base to apex. It is perhaps this species which Butler speaks of (Proc. Zool. Soc. Lond., 1877, 400) as lativittalis, Walk.; the true lativittalis (which is a species of Thinasotia, and most certainly does not occur in New Zealand) is superficially somewhat similar, but has the thorax wholly brown, and many other points of distinction. Two specimens taken in a swamp near Hamilton in January. 10. Cr. apicellus, Z. (Crambus apicellus, Z., Mon. Cr., 31.) Male.—24–25 mm. Head snow-white, sides of crown ochreous-brown. Maxillary palpi white, towards base externally reddish-ochreous-brown. Labial palpi moderate, white, externally reddish-ochreous-brown. Antennæ dark fuscous. Thorax ochreous-brown, posteriorly on sides paler and whitish-tinged, with a broad central longitudinal white stripe. Abdomen whithsh-ochreous. Legs whitish-ochreous, suffused with dark fuscous beneath. Forewings moderate, posteriorly dilated, costa gently-arched, apex rounded-acute, hindmargin rather oblique, distinctly sinuate; red-dish-ochreous-brown, much lighter towards inner margin; a slightly curved narrow white streak from costa before middle to costa a little before apex, enclosing a slender brownish-ochreous costal streak; a small triangular white spot on hindmargin above median streak; a moderate central longitudinal snow-white streak from base to hindmargin, rather attenuated at base, slightly sinuate in middle, and very slightly curved towards hind margin, lower edge somewhat irregular beyond middle; a whitish suffusion along inner margin from base to beyond middle, very narrow at base, posteriorly indistinct; three elongate ill-defined black dots on hindmargin beneath median streak; a fuscous hind-marginal line, bordering the white markings: cilia shining grey-whitish, at base white. Hindwings fuscousgrey, towards base suffused with whitish-ochreous; cilia whitish-ochreous. A handsome species, very distinct by the peculiar form of the costal streak, and the sharply-defined small white triangular spot on hindmargin. Occurs at Hamilton, Christchurch, and at the foot of Mount Hutt, frequenting swampy places in January.
