TRICHOPHYSETIS.— NIPIIOPTRALIS. 181 



margiu near the outer angle; a subapical line from below the costa to the centre of outer 

 margin. Hind wing with the inner portion of the outermost of the double autemedial lines 

 conspicuously black; the postmedial line obli([uc and reaching the margin at the anal ann-le ; 

 an oblique line from the costa before the apex to near the centre of outer margin. 



The maxillary palpi in this genus are large and thickly scaled; the labial pal|)i long, 

 porrcet, and thickly scaled, the scaling apt to wear off the third joint. 



NIPHOPYRALIS, g. n. 



Male. Antennae strongly bipectinated. Palpi slight and upturned. IVire wiug with a 

 costal nervure ; two subcostals from before the end of the cell ; the third and fourth stalked 

 from the end; the fifth from below the end; upper radial from the discocellulars ; lower 

 radial and two medians from close to the lower angle of cell ; the first median from before 

 the angle ; submedian and internal nervures. Hind wing with the costal anastomosing with 

 the first subcostal to near the apex; the cell open; the radial and third median stalked and 

 given off from the same point as the second median ; third median from nearer the base ; 

 interno-median, submedian, and internal nervui-es. 



Niphopyralis nivalis. (Plate CLXXIV. fig. 6.) 



Expanse f inch. 



Male. Fore -wing with the margins narrowly snowy white; the disk slightly sull'used 

 with pale yellowish brown ; an indistinct dark waved antemedial band from the subcostal 

 nervure to near inner margin ; an indistinct dark-outlined lunule beyond the cell ; the apex 

 more broadly white, which colour extends inwards from the margin along the first median 

 nervule forming a small triangular spot. Hind wing, head, thorax, and abdomen snowy 

 white; pectinations of antennie brown. 



Niphopyralis albida. (Plate CLXXIV. fig. 25.) 



Expanse d § inch. 



Male. Wings white, with a slight fuscous suffusion and fuscous antccilial line. Under- 

 side of fore wing with the costal and apical areas suffused with fuscous. Antennae brownish. 



Differs from nivalis and contaminata in the antennae of the male being simple; the palpi 

 shorter. 



Niphopyralis contaminata. (Plate CLXXIV. fig. 14.) 



Expanse /o inch. 



Male. Head, thorax, and abdomen pure white. Fore wing white ; the area beyond the 

 cell suffused with fuscous, leaving the apex and marginal line white ; a blackish blotch on the
