H. biterminosa Dyar (19 g) is likewise similarly coloured and marked, but very conspicuous owing 
to the light reddish distal part, which colour appears chiefly in two broad stripes, one from the distal half of 
the reniform macula obliquely upwards to the apex, the other between the submedian fold and lower median 
vein as far as the margin, above it somewhat darker; the blackish colour extends from the margin as a pointed 
triangle to the lower cell-angle, the coniform macula being very large and broad, like a semicircle; the distal 
transverse line is quite extinct. From Mexico (Zacualpan). 
H. degenerans Dyar (19 g). Forewing light coppery reddish or yellowish-brownish, the whole cell 
densely strewn with black, so that it appears as a dark wedge-shaped spot with the apex at the base. Of other 
markings there are only at the costal margin the beginnings of double transverse lines, and the posterior line 
as an indistinct double row of dots. Maculae absent, except the reniform macula being in some specimens marked 
as a whitish brightening behind the lower cell-angle; a black basal ray is present; the undulate line is here 
marked by white dots on the veins, the marginal area is shaded with blackish. Hindwing diaphanous white 
with a dark margin. From Mexico. 
H. disticha Morr. (19 g). Forewing grey, strewn with brown and behind the median line dusted with 
brown, with double transverse lines filled up with grey; of the maculae only the yellowish reniform macula, 
is distinct, in a grey ring and encircled with brown; the grey undulate line is quite indistinct with a dark brown 
spot before it at the costal margin. Hindwing greyish-brown. From Texas. 
H. dilecta Echo. (19 g) has light grey forewings tinted flesh-coloured reddish and strewn with brown, 
with indistinct single transverse lines and behind the median line brown dusting; the reniform macula is in 
the $ reddish-brown, in the $ grey, encircled with black, surrounded with whitish dots in the lower half; before 
the indistinct grey undulate line there are single black dots. Hindwing ochreous-brown, towards the base lighter. 
Colorado, Arizona. 
H. orbiculata 8m. (19 g) is on the forewing grey, dusted and strewn with dark brown, below and 
behind the cell tinted reddish, with a black basal ray; the anterior transverse line indistinctly double, on the 
proximal-marginal vein very pointedly proximally angled with the long pointed coniform macula behind it, 
the posterior double transverse line filled up with white; the whitish, very oblique, triangular ring-macula 
is above and below open, below connected with the reniform macula: before the whitish undulate line small 
black sagittae. Hindwing brown. Colorado. 
H. nivciguttata Grt. (19 g) has grey forewings strewn with black and brown, on the folds and at 
the proximal margin tinted ochreous, with a dark basal ray, double transverse lines and small maculae encircled 
with black, the reniform macula below filled up with black, with 2 white dots therein; the subterminal area 
before the feebly dentate undulate line darker than the marginal area. Hindwing brownish-black. California. 
H. elaeochroa Dyar. Forewing smoothly scaled, yellowish olive-grey, in the basal and marginal areas 
more intensely yellowish; the fine transverse lines are blackish, the proximal line on the proximal-marginal 
vein dentate, the distal line finely dentate; both the upper maculae are filled up with blackish; undulate line 
extinct. Hindwing blackish, in the disc whitish. Expanse of wings: 35 mm. Peru (Cuzco). 
H. ruficana Drc. (19 g). Forewing reddish-brown, basal area, both the maculae forming an at and 
the marginal area greyish-white, of which colour are also 2 fine slightly undulate transverse lines, between them 
in the centre of the proximal margin 2 black spots. Hindwing light brown. Peru and Bolivia. 
H. melanopis Drc. (= cillutincarae Zerny) (19 h) has deep dark brown forewings with fine, broken, 
black transverse lines, at the cell-end an indistinct black spot; marginal area light brown with a submarginal 
black undulate line; fringes dark brown. Hindwing yellowish-white, at the margin somewhat darker. Expanse 
of wings: 35 mm. Peru, Bolivia. 
H. stenorena Drc. Forewing dark red-brown, in the basal area green, a round green spot in the cell, 
at the cell-end with a large, greenisli-white spot; the proximal margin is pinkish-brown; the broad olive-green 
undulate line is bordered with black, at the margin there is a row of white dots. Hindwing dark brown with 
a green marginal line. Expanse of wings: 38 mm. Peru. 
H. olivescens Drc. has an olive-green thorax and forewing with a black dentate anterior transverse 
line; the light ring-macula is quadrangular, the reniform macula whitish, bordered with black; before the light, 
faint undulate line in the centre some black spots. Hindwing brownish-black with olive-green fringes. Expanse 
of wings: 44 mm. Peru. 
H. poliorhoda Drc. Forewing dark red-brown, densely strewn with silvery grey, with a faint grey 
spot at the cell-end and a dark brown distal transverse line. Fringes brown. Hindwing white, costal margin, 
apex and margin dusted with brown. Expanse of wings: 36 mm. Peru.
