margin 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 antemedial lines 
conspicuously black ; the postmedial line oblique and I'caching the margin at the anal angle ; 
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 palpi long, 
porrect, and thickly scaled, the scaling apt to wear off the third joint. 
NIPHOPYRALIS, g. n. 
Male. Antennse strongly bipectinated. Palpi slight and upturned. Fore wing 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 nervures. 
Niphopyralis nivalis. (Plate CLXXIV. fig. 6.) 
Expanse f inch. 
Male. Pore wing with the margins narrowly snowy white; the disk slightly suffused 
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 antennse brown. 
Niphopyralis albida. (Plate CLXXIV. fig. 25.) 
Expanse S § inch. 
Male. Wings white, with a slight fuscous suffusion and fuscous antecilial line. Under- 
side of fore wing with the costal and apical areas suffused with fuscous. Antennse brownish. 
Differs from nivalis and contaminata in the antennse of the male being simple; the palpi 
shorter. 
Niphopyralis contaminata. (Plate CLXXIV. fig. 14.) 
Expanse 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
