(? ) Leucania sulcana, sp. nov. 



(Plate IX., fig. 3'.) 



Bodi/, stout. Thorax, pale oclireous. Abdomen, extending about one- 

 fourth of its length beyond the hind-wings ; fuscous ; the male with pale 

 fawn-coloured tuft ; pale fawn-colour beneath. AntemuB of male slightly 

 serrated, and thickly ciliated. Palpi porrect, shghtly 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 tibiae 

 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, m others to yellow ; margin of costa 

 brownish-ochreous, inclining to reddish-ochreous in some specimens ; along 

 each side of the nervvu^es, and also midway between the branches of the 

 nervures, runs a groove ; the grooves forming parallel striae 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 

 nervu.re ; a small cluster of blackish scales in the discoidal cell at the point 

 where the third branch springs from the median nervure ; the subterminal 

 line represented by a blackish point on the first inner subcostal nervure,
