H. approximans Wkr. (= pollex Dyar) (113 d). Head and thorax brownish-grey, abdomen intermixed approxi- 
with ochreous hairs. Forewing lilac brownish-grey, basal area darkened, without a distinctly prominent ante- mans. 
median line, with a large extinct discal spot; the broad faded postmedian band slightly separated from the 
subterminal band by a faded lighter interspace. On the hindwing with a small discal spot both the lines are 
united into an indistinct broad band. Panama, Venezuela. 
H. darlingi Dyar (113 d) is very similar to the preceding species, the collar of a brighter ochre colour, darling!. 
the markings less bright and contrasting, the costal-marginal portion lighter than in approximans, the discal 
spot more shaded, the abdomen somewhat more brownish. Larva with a cerise head, whitish with black angular 
markings and spots, whitish thorns with light branches; it lives on the Cachu tree (Anacardiacea). Panama, 
tendex f.n. (113 e) is presumably a southern form with narrower more elongate wings with a more produced tendex. 
apex, ground-colour more lilac, more contrastingly marked, the discal spot thicker, rounder, with broader 
transverse lines, but the subterminal shadow much narrower and paler, the apical marginal shadow broader, 
the small white spot in it much smaller. Hindwing more triangular with a longer anal angle and a straight 
margin, distinct discal spot, the two transverse lines much more separated, the interior line almost straight, 
close at the discal spot, the exterior line broader, close at the margin. Abdomen lighter yellow'. Type: 1 
from the Rio Pachitea, Porto Alegre (Rio Grande do Sul). A very similar form with still narrower forewings, 
a more oblique distal margin and a narrower postmedian line, from Surinam, shows the transverse lines of the 
hindwing much closer together: — guayanensis /. n. (113 e). guayanen- 
H. lilacinex sp.n. (113 e) is intermediary between darlingi and umbrata , larger than the latter, m ac - ine 
with a more pointed apex of the forewing, the forewing quite light lilac grey, basal area darkened as in darlingi. 
the lower end of the large discal spot touches the postmedian band which is somewhat narrower than in umbrata 
and likewise bifurcates Y-like between 6 and 7. Subterminal band light as in lendex, but somewhat broader, 
the light apical streak narrow and distinctly contrasting. Hindw ing darker sooty blackish, the two transverse 
lines distantly separated, narrow, the interior line close at the cellular streak, behind the distal line the marginal 
area is narrowly lighter lilac. Abdomen yellowish ochre, collar with long yellowish hair. According to a $ from 
Balzapamba (Ecuador); type in the Coll. Hopp-Chaiiottenburg. 
H. umbrata Schs. (113 e) is closely allied to the two preceding species and variable, but discernible umbrata. 
by the very broad postmeclian band which is distinctly separated from the subterminal band. Thorax lilac 
brown, strongly haired ochreous, abdomen ochreous. Forewing dull pinkish lilac brownish, basal area darkened, 
bordered by the antemedian line, discal spot large, distinct, more prominent than in the preceding species. 
Hindwing with fine dark veins, the two lines separated. Guatemala; Costa Pica; Colombia. 
H. murex Dyar (113 e, f) is a smaller species with somewhat falcate forewings, drab, thorax somewhat murex. 
darker, abdomen with ochreous hair, the transverse lines almost quite obsolete, the exterior one somewhat 
better marked at the costal margin, with a small light spot behind it; subterminal line broadly shaded, nearing 
the margin between 2 and 4. Hindwing between the two lines and before the margin somewhat lighter. Surinam. 
H. nigripes sp.n. (113 f) is somewhat similar, smaller, more slender, apex more produced, the small nigripes. 
hindwing rounded. Forewing purple blackish, marked darker smoky black; basal area darkened, the postmedian 
line confluent with the subterminal shadowy band which projects but little between 2 and 4; the dark discal 
streak in a dark shadowy spot. Hindwing without the discal spot, with 2 shadowy bands which are distantly 
separated, the interior line extends through the cross-vein. Abdomen golden ochreous brown, with blackish 
bands. Tibiae and tarsi black. Muzo (Colombia); type in the Coll. Hopp-Charlottenburg. 
H. cedomnibus Dyar to a certain degree resembles pauper and athlia ; it is larger and the forewing is cedomnibus. 
more quadrangular not falcate at the apex, light drab, with somewhat lighter obsolete transverse lines, the 
absent discal spot is indicated by a light cellular spot before it, at the apex another whitish spot. Hindwing 
quite indistinctly marked, the marginal area somewhat lighter with an irregular interior border. Carabaya (Peru). 
H. pachobex Dogn. is likewise very similar to athlia, forewing less rounded, margin more oblique and pachobex. 
straighter, postmedian line correspondingly also more oblique and nearer to the discal spot. Ground-colour 
less blackish, but in the $ blacker; $ more marked, beside the two light transverse lines another median line. 
Pacho (Colombia). Expanse of wings: 44, $ 60 mm. 
H. schausi Dyar (113 f). Lilac grey, with a slight (in the $ somewhat more) rosy tint, abdomen with schausi. 
ochreous hair. Forewing with somewhat lighter transverse lines, the distal line near the discal spot and inwards 
band-like dark, narrowing down towards the inner margin; behind the indentation of the subterminal line 
in its upper half dark marginal filling with a small whitish apical spot. Hindwing with 2 feeble distal lines 
without a discal spot. Venezuela; Guiana; Peru. 
H. canitia Stoll (113 f) is very similar to schausi, larger, with narrower wings, with an oblique distal canitia. 
margin, of a greyer colour, more intensely marked, the cell before the discal spot light, basal area dark, the 
distinct antemedian line bordered with light towards the base, subterminal line more distinct. On the forewing 
the lines are represented by two shadowy bands. The $ is much larger and greyer. Venezuela; French and 
Dutch Guinea.
