transverse line forms 3 high bows, the posterior line being dentate on the veins with white dots behind it; ring- 
macula large, round, the reniform macula distally with 3 yellowish white dots and in the lower proximal angle 
with one; between them a broad, faded discal shade; the undulate line forms below the costal margin and in 
the centre rather large bows turned towards the margin. Hindwing diaphanous light grey with a darker discal 
dot and marginal line which is interrupted on the veins. Base of fringes yellowish. Mexico (City), September. 
H. piacularis sp. n. (18 f). Forewing on the light brownish ground uniformly dusted red-brown across piacularis. 
the whole surface of the wing; the proximal transverse line is finely brown, forming two angular bows distally 
and an acute angle towards the base in the cell on the fold, the posterior line being dentate on the veins; the 
coniform macula is encircled with brown only in the distal half, the upper maculae are faintly lighter 
yellowish, finely encircled with brown, the ring-macula a circle, the reniform macula distally very slightly 
concave, at the distal margin somewhat more distinctly yellow, with a fine, brown, concentric line; the median 
is in the distal half blackish and strewn with whitish; median line on the lower cell-angle almost rectangularly 
flawed; the marginal area is hardly darker than the subterminal area, the undulate line parting both forms 
towards the costal margin a small bow, in the centre a larger bow towards the margin. Hindwing brownish- 
grey with reddish-yellow fringes. 2 $$ from Mexico (City), taken in September by Rob. Muller. Type in 
the Coll. Draudt. 
Sect. II. Antennae with short double combs. 
H. felova Dyar. Here the comb is as long as or somewhat longer than the antennal shaft. Forewing jclova. 
yellow, densely strewn with red-brown, in the distal half dusted with brown, with brown, single transverse 
lines being dentate on the veins; maculae of the ground-colour, surrounded with a plain brown, the reniform 
macula with white dots at the angles; the median shade is flawed at the lower cell-angle; marginal area shaded 
with dark, the undulate line appearing as yellow spots below the apex. Hindwing blackish brown. Expanse 
of wings: 32 mm. Mexico (Jalapa). 
H. danastia Dyar (18 f) has the teeth of the antennal comb shorter than the width of the shaft, danastia. 
Forewing yellow, strewn with red-brown and intensely dusted with purple brown, so that the ground-colour 
remains only in the basal area, the maculae, and subterminally; the transverse lines are but little visible in 
the dark shading, the median shade being angular at the lower angle of the cell; both the upper maculae exhibit 
whitish dots in their bordering. Hindwing blackish-brown with lighter fringes. Mexico (Jalapa). 
Sec t. III. Antennae serrate with ciliary tufts. 
H. zinda Dyar (18 g). Forewing yellow, strewn with red, with fine single transverse lines being dentate zuida. 
on the veins, and a median shade being rectangularly flawed at the lower cell-angle; maculae surrounded with 
red-brown, the round reniform macula is situate in a dark red-brown shade extending subapica-lly farther 
towards the costal margin, and exhibits below 3 white dots; the marginal area is uniformly filled up with dark 
red-brown, and on the middle radial branch it projects pointedly proximad, the veins in it being finely striped 
dark. Hindwing blackish-grey, tinted reddish at the margin. Expanse of wings: 33 mm. Mexico (Zacualpan) 
in August. 
H. multesima sp. n. (18 f) has yellow forewings finely strewn with blackish grey, whereby they multesima. 
exhibit a loam-coloured yellow tinge, only the area of the proximal margin being strewn with somewhat more 
brownish-red; the subbasal line is red-brown, double; the anterior transverse line forms 3 bows, the two upper 
ones being large and flat, that below the inner-marginal vein being much higher; all the three maculae finely 
encircled with brown, the reniform macula with a fine brown concentric line and 2 white dots in the two lower 
angles and a more yellowish dot above distally; the broad median line is on the subcostal rectangularly flawed 
distally, on the cellular fold rectangularly flawed proximally and behind the lower cell-angle in an acute angle 
distally, the space between it and the pointedly dentate postmedian line darkened as a blackish-grey band, 
the subterminal area again lighter; this is the only species in which the subterminal line appears in the grey 
marginal area as a uniform, light yellowish, coherent undulate line. Hindwing blackish grey with yellowish 
fringes. Mexico (City), taken by Rob. Muller in September. 
H. catadea Dyar (18 f). Forewing yellow, strewn and dusted with red-brown; the subbasal line extends catadea. 
as a straight brown line from the cell to the angle of the proximal margin, the proximal transverse line is indis¬ 
tinctly double, almost straight, only forming below the inner-marginal vein, like in multesima , a bow projecting 
far distally, the fine distal transverse line is dentate on the veins, the median line is somewhat angular in the 
cell and forms a very acute angle below the reniform macula; coniform macula only distally surrounded with 
brown, the upper maculae somewhat lighter yellow, distinctly surrounded with dark brown, without white 
dots, the dark marginal area terminates on the penultimate subcostal branch obliquely cut off and is here the 
darkest. Hindwing blackish with reddish fringes. Mexico (City) in October. 
H. parafea Dyar is very similar to catadea (18 f), smaller, the lines are browner and much less con- parafea. 
trasting; the maculae are smaller, the reniform macula below with a white bent spot and a small one in the 
upper distal angle, pupilled with a red line. Subterminal area yellow, traversed by red veins, marginal area 
dark brown, with a pointed projection towards the base on the middle radial branch. Mexico (City).
