H. petena Schs. (112 g) resembles hamata, thorax almost black, abdomen dark brown, only the anus petena. 
rusty red; forewing dark brown with a slight carmine tint, the double postmedian line shadow-like as in hamata. 
Hindwing in the inner-marginai portion pinkish-brown, at the base with ochreous hair. Abdomen of $ olive- 
brown with yellow hair, wings as in acuta-Q more distinctly marked. From a great number of cocoons in a large 
common web the imagines crept out during a period of 2 years. Guatemala. 
H. tapareba Ky. i. 1. ? (112 g) is dark brownish-grey, the postmedian line quite obsolete, at the cell-end taparela. 
with an oval brownish-grey ring filled with yellowish and with a dark centre; both the transverse lines are 
sometimes feebly bordered with yellowish-white. Abdomen sooty ochreous brown. Guiana, Amazons. The 
species, which is in the British Museum, seems to have been never described. 
H. tapabex Dyar (112 g) is on the forewing, particularly basad, lighter than tapareba. with traces of 3 tapabex. 
indistinct slightly darker transverse shadows, the discal spot as in tapareba. Abdomen of a brighter ochre colour, 
ventrum rusty yellow, with a brownish-grey lateral stripe. The $ is purple brown, forewing with an angular 
apex, at the base darker, with a large discal spot and a broad straight distal band. Venezuela, Colombia. 
H. dyarex Schs. Head and abdomen ochreous, thorax brown. Fore wing loamy brownish as far as the dyarex. 
antemedian line which meets the postmedian line at the inner margin, the area behind it below vein 4 somewhat 
darker brown, above purple grey; at the cell-end a dark streak broadly edged with loamy whitish. Hindwing 
whitish-grey, basad and at the inner margin with dull yellowish scales, with a fine dark discal streak. Expanse 
of wings: 45 mm. Quirigua (Guatemala). 
H. rosacea Schs. Head and thorax yellowish olive brown, abdomen dark brown, with ochreous hair, rosacea. 
Forewing pink with the usual dark olive brown basal oblique band, the veins in the marginal area finely brown, 
at the cell-end with a large olive brown oblique spot; posterior transverse line fine dark, at the margin a 
brownish shadow ending pointed at the margin on vein 3 and touching the postmedian line below 7. Hindwing 
pink, at the inner margin darker with a fine postmedian line and a feeble subterminal shadow. Expanse of 
wings: 46 mm. Costa Rica. 
H. thaumex n. sp. (112 g) is very similar to rosacea, but more lilac pink, anterior body and the basal thaumex. 
oblique band deep dark brown like the narrow oblique discal spot, the almost straight postmedian line very 
distinct, with a feeble antemedian line vertical to the inner margin; behind the postmedian line the whole 
marginal area is dark brownish-grey, at the apex parted by a whitish conspicuous spot, only at the anal angle 
before and behind the subterminal band, which is only here visible, lighter like the ground-colour. Hindwing 
somewhat greyer than the forewing, at the inner margin with pink hair, and with 2 feeble darker postmedian 
shadowy lines. Abdomen ochreous, with blackish-brown bands. Western Colombia (Type in Coll. Niepelt). teratex. 
—- teratex f.n. (112 h) may be a form of it, somewhat smaller and instead of the lilac pink colouring ash-grey, 
the conspicuous greyish brown discal spot larger; the thorax is blacker, the ochreous abdomen with hardly 
darker bands. Surinam; 4 presented by Schatjs to the Berlin Museum, where the type is too. 
H. subfasciata Dogn. likewise belongs yet near hamata. Body brown, base of abdomen with some sulfasciata. 
ochreous hairs. Forewing earthy ochreous grey, basad and in the inner-marginal half somewhat lighter, the 
basal oblique band brown; the fine antemedian line is hardly visible, interrupted below the cell, the postmedian 
line darker, parallel to the margin, behind it a feeble subterminal shadow', at the cell-end a dark streak, the 
apex somewhat darkened. Hindwings likewise darker, with 2 postmedian transverse lines. Beneath the two 
postmedian lines are inclined to form a darkened band, whereby the species is easily separated from hamata, 
beside the different colouring. Expanse of wings: 48 mm. Southern Peru (Chaquimayo). 
H. iilacina Dogn. described according to but 1 female has light lilac wings, the forewing and hindwing lilacina. 
only with an obsolete hardly visible discal spot, the forewing without any transverse lines, the hindwing with 2 
parallel, rounded, feeble postmedian lines. Centre of thorax ochreous brown, patagia lilac, abdomen brown. 
French Guiana. 
H. tiphys Dogn. Anterior body blackish-brown with single ochreous hairs, abdomen bright ochreous, tiphys. 
ventrum brown. Forewing violet-blackish wdth darker veins, with the usual blackish-brown basal oblique 
band and on the cross-vein an intense blackish-brown indistinctly defined strigiform spot; behind the middle 
two very feeble shadowy lines parallel to the distal margin; marginal area in the lower half and at the apex 
lighter. Hindwing without distinct transverse lines, but the space between the two lines somewhat lighter. 
Sao Paulo (Brazil). 
H, gracilex Dogn. (112 h) is a smaller species allied to the preceding ones, the apex of the forewing gracilex. 
somewhat less falcate. Thorax brown, abdomen ochreous. Forewing pinkish or lilac grey, marked brownish; 
the forewing with the usual brown basal oblique band, a discal shadow and a feeble postmedian line behind 
it, the feeble subterminal shadow vanishes in the darkened apex which shows a small lighter spot. Hindwing 
with 2 feeble postmedian transverse lines. Amazons (Sao Paulo de Oliveira). 
H. mymex Dyar (112 h). Thorax black, abdomen ochreous brown, with blackish-brown rings, mymex. 
Forewing hardly falciform, purple brownish or more lilac pink, at the apex darkened; the anterior transverse
