Hermenias dirupta spec. nov. (fig. 353) 
$ 19 mm. Head white, sides suffused with blackish. Antenna brownish- 
black, scape white, blackish below. Palpus white, basal segment and an 
oblique broad median transverse band of median segment black; this 
segment also with a dark fuscous subapical transverse band less oblique, 
connected below with transverse band; terminal segment irrorated with 
dark fuscous-grev. Thorax white, slightly irrorated in middle with blackish, 
basal half of tegula black, mixed with brown posteriorly. Abdomen pale 
ochreous, apex slightly suffused with grey. Legs pale greyish-ochreous, 
anterior and median tibia and tarsus blackish, white-ringed. Fore wing 
elongate, rather narrow, moderately dilated, costa hardly curved, slightly 
bent at 4 / 5 , apex subobtuse, termen straight, little oblique, rounded 
beneath. White, moderately speckled with black and grey along costal 
third, with light brown elsewhere, tending to form transverse strigulae 
and a thin retination posteriorly. Markings black with dark brown tinge. 
Costal edge black anteriorly; costa transversely strigulated with black, a 
small transverse black mark beyond 1 / 4 , clavate below; a round dot on 
middle of costa and three smaller round dots along posterior fourth of 
costa to before apex; a denser blackish irroration along and below third 
fourth of costa forming more distinct transverse strigulation ; a wedge- 
shaped, inwardly oblique transverse streak on dorsum beyond base 
reaching to above fold; an elongate longitudinal, somewhat inwardly 
oblique patch below middle of disc along about second fourth of wing; 
anterior edge of this patch truncate, upper edge with a small median 
projection; posterior edge of patch inwardly oblique, thus upper angle 
acutely projecting; lower edge of patch with a narrow stalk from middle 
to 2 / 5 of dorsum ; a subtriangular slightly inwardly oblique spot on dorsum 
before tornus, with top truncate, not reaching middle of disc; anterior 
edge of this spot somewhat undulate, oblique, posterior edge straight, 
hardly inwardly oblique; a moderate streak from disc above middle at 4 / 6 
of wing length to apex, anterior half dilated to a subquadrate patch, with 
upper edge bent, lower edge of patch with two slightly curved vertical 
streaks; anterior streak brown, narrowed below, to tornus, posterior streak 
black, narrow, to termen below middle; a narrow black line from lower 
edge of patch to termen below apex and along upper 3 / 4 of termen. Cilia
