26 Transactions.— Zoology. 
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 suffu- 
sion 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 Thina- 
sotia, 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. Antenne 
dark fuscous. Thorax ochreous-brown, posteriorly on sides paler and 
whitish-tinged, with a broad central longitudinal white stripe. Abdomen 
whitish-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 longi- 
tudinal 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, pos- 
teriorly 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 fuscous- 
grey, 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 hind- 
margin. 
Occurs at Hamilton, Christchurch, and at the foot of Mount Hutt, 
frequenting swampy places in January.
