26 Transactions. — Zooloyy. 



central longitudinal silvery-white streak from base to hind margin, 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., Mori. 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. Antennae 

 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.
