32 Transactions. — Zoology. 



Not uncommon at light in Christchurch during March ; Mr. E. W. 

 Feveday has also taken it commonly at Mount Hutt in January. 



The species does not hear the slightest affinity or resemhlance to 

 Aphomia, which differs widely in venation, belonging as it does to another 

 family, and further has entirely different, very short, ascending palpi in the 

 male, a character of which Butler, though describing a male, was evidently 

 unaware. 



17. Or. xanthogrammus, n. sp. 



Male. — 22-24 mm. Head reddish-ochreous, mixed with grey on face ; 

 anterior margin of eyes, lower part of face, and a small spot on crown 

 whitish. Maxillary palpi whitish, towards base externally reddish-ochreous. 

 Labial palpi rather long, reddish-ochreous, internally whitish, beneath white 

 at base. Antenna? dark fuscous. Thorax light grey, somewhat mixed with 

 whitish, with a spot on each shoulder and centre of back reddish-ochre- 

 ous. Abdomen grey- whitish, suffused with light ochreous. Anterior and 

 middle legs dark grey, apex of middle tibiae and of first joint of tarsi 

 whitish ; posterior legs whitish, tarsal joints suffused with dark grey except 

 towards apex. Forewings moderate, posteriorly dilated, costa slightly 

 arched, somewhat sinuate before middle, apex rounded, hindmargin rather 

 oblique, strongly rounded ; whitish, becoming clearer white towards costa, 

 and grey towards inner margin posteriorly ; a short dark brownish-grey 

 mark on inner margin at base ; an oblique irregularly oval dark brownish- 

 grey blotch in disc towards base, its anterior extremity connected with base 

 by a short streak, its posterior extremity almost touching inner margin at 

 ^ ; a slender dark brownish-grey transverse fascia from middle of costa to 

 middle of inner margin, becoming much thicker on lower half, suffused on 

 costa, upper half irregularly dentate above middle, sending a sharp tooth 

 inwards in middle ; a second slender dark brownish-grey transverse fascia 

 from costa at f to inner margin at f , strongly and abruptly dilated on lower 

 third, upper two-thirds twice curved inwards, sending a sharp tooth out- 

 wards between the curves, anterior edge below middle emitting two or three 

 slender lines along veins to centre of disc ; this fascia is margined posteriorly 

 by a suffused white fascia, beyond which is a brownish-grey hind-marginal 

 band irrorated with whitish ; a straight slender bright ferruginous streak 

 along submedian vein from base to second fascia, indistinct towards base ; 

 a more conspicuous straight slender bright ferruginous streak from base to 

 anal angle ; both these streaks intersect all the dark markings they meet ; 

 lower half of hindmargin tinged with ferruginous : cilia grey, with a white 

 basal line ou upper half of hindmargin. Hindwings grey- whitish, with a 

 faint cloudy grey line a little before hindmargin, and a grey hind-marginal
