what lighter fillings, the maculae inclusive of the coniform macula finely encircled with black, the reniform " f - 
macula filled up with small white spots; through the darker shaded marginal area runs the dark undulate line. 
Hindwing in the $ whitish, in the $ brownish-grey, at the margin darker. From Mexico (Tehuacan, Puebla),

finely encircled with black, the reniform macula whitish, pupilled brown and towards the base concave, between 
them a finely undulate median line; the light undulate line exhibits proximally small black sagittae; in the 
marginal area above and below the middle radial faded black longitudinal stripes. Hindwing greyish-brown,

dusted with grey and strewn with scanty white scales, with single black transverse lines, the posterior line 
dentate. Maculae absent, instead of them there are behind the cell-angles small spots of long white scales; 
of similar small spots the undulate line is composed, and proximally they are bordered with black; at the 
base of the fringes an ochreous-yellow line. Hindwing dark brown, towards the base lighter. Fringes like 
on the forewdng. Expanse of wings: 44 mm. Described from Peru (Acopampa).

H. griseata Hmps. Forewing purple grey, strewn with dark brown, with indistinct blackish transverse griseata. 
lines, the posterior line feebly dentate; all the 3 maculae marked by a border of black scales, the coniform 
macula only at the apex, the ring-macula and reniform macula only laterally; the undulate line consists of a 
row of small dark brown spots in the spaces between the veins, being in the middle shaped like sagittae. Hind¬ 
wing grey, dusted with brown, with darker veins and white fringes. Expanse of wings: 34 mm. From Peru. 
H. modesta Morr. (19 f). Forewing purple grey, strewn with dark brown, in the distal half of the discal modesta. 
area dusted with brown, with single blackish transverse lines and median line; maculae small, indistinctly 
encircled with brown, the reniform macula reddish, in the lower end pupilled blackish and often with a white

H. fasciata Sm. (19 f) has bluish-grey forewings strewm with dark blackish-browm, behind the median fasdata. 
line dusted with blackish-brown, with rather indistinct transverse lines, the posterior line being uncommonly

the ring-macula is absent, the reddish-brown reniform macula is surrounded by blackish; the undulate line 
is represented by black dots in red-brown rings. Hindwing greyish-brown. New Mexico. 
H. plenipotentia Dyar (19 f). Purple-reddish brown, strewn with dark, the subterminal area, the costal pienipoten-

three maculae finely encircled with black, the reniform macula distally bordered with white; undulate line light, 
the narrow marginal area behind it purple black, before it black, white-dotted streaks on the veins. Hind- 
wing whitish, at the margin darkened, in the $ brownish-grey. Mexico (Zacualpan) 
H. umbera Dyar (19 f) is larger with more pointed forewings, without any white at the reniform umbera. 
macula, strewn with a much darker purple black, so that almost only the reniform macula and the undulate 
line show through purple-reddish, the subterminal area is also dark; the posterior transverse line is more dentate, 
very distinctly double. Hindwing whitish, at the margin darkened with darker veins. From Mexico (Zacualpan).
