(Read before the Philosophical Institute of Canterbury, 26th Nov., 1879.) 
(?) Leucania sulcana, sp. nov.. 
(Plate IX., fig. 8'.) 
Body, stout. Thorax, pale ochreous. Abdomen, extending about one- 
fourth of its length beyond the hind-wings; fuscous; the male with pale 
fawn-coloured tuft; pale fawn-colour beneath. Antenne of male slightly 
serrated, and thickly ciliated. Palpi porrect, slightly ascending, extending 
considerably beyond the head; third joint slender, elongate-conical, about 
one-third the length of the second; thickly clothed; the second joint with 
long, and the third joint with short hairs. Legs rather stout; hind tibie 
with four spurs, each pair consisting of one long and one very short spur ; 
the short spurs with a broad band of black hairs. 
Fore-wings, pale ochreous, very sparsely irrorated with blackish scales, 
more especially in the regions of the postcostal and anal nervures, and apex; 
rather narrow, acute at the tip, outer margin oblique, a deep longitudinal 
depression extending from the base and running midway between the 
median and anal nervures to near the anal angle, the inner margin also 
being depressed, and the anal nervure running along the ridge between the 
depressions; a less deep longitudinal depression between the median and 
postcostal nervures; a brown shade runs longitudinally from near the 
centre of the disk to the hind margin, the shade inwardly dark and termin- 
ating abruptly at the median nervure and its third branch, and anteriorly 
fading away into the ground colour; a similar shade along the anterior side 
of the groove formed by the depression between the median and anal ner- 
vures ; a narrow, dusky shade along the middle of the inner margin, and a 
short dusky streak near the base of the inner margin; the brown shades in 
some specimens incline to red, in others to yellow; margin of costa 
brownish-ochreous, inclining to reddish-ochreous in some specimens ; along 
each side of the nervures, and also midway between the branches of the 
nervures, runs a groove; the grooves forming parallel striæ of ridge and 
furrow; the ridges pale and the furrows dusky; each central furrow 
terminating in a blackish marginal dot or point; the nervures rather paler 
than the disk of the wing ; a blackish central spot at the apex of the acute 
angle formed by the fork of the second and third branches of the median 
nervure; a small cluster of blackish scales in the discoidal cell at the point 
where the third branch springs from the median nervure; the su 
line represented by a blackish point on the first inner subcostal nervure,
