H. caucanex sp. n. (113 h) is allied to remex, ground-colour almost lilac whitish, abdomen lighter caucancx. 
ochreous, antemedian line distinct, below the cell strongly removed basad. submedianly thicker, the subterminal 
shadow much broader, anal angle and apical spot very contrastingly light ; hindwing with a distinct discal 
spot, close at it the interior line, the exterior line thrice as broad, shaded darker. Type: $ from Popayan, Dep. 
Cauca (Colombia), co-type: $ from Icononzo (Pandi, Colombia), both in the Coll. Hopp-Charlottenburg. 
H. livex Dijar (113 h). Thorax brownish-grey, abdomen with ochreous hair. Fore wing similar to livex. 
fulviventris , lighter brownish-grey, more contrastingly marked, the antemedian line proximad, especially at 
the costal margin more profusely marked white, postmedian line narrower. Lines on hindwing close together, 
exterior line broader, with a somewhat irregular distal border. The $ has a more faded marking, thorax and 
abdomen brown, the abdomen laterally and at the end with ochreous hair. It may be H. subcana Wkr. which 
was described only according to a $. 
H. discutex sp. n. (113 h) is likewise very similar to livex and especially to fulviventris, but the abdomen discutex. 
is quite ochreous as in livex. Forewing almost exactly that of fulviventns, the discal spot smaller and more 
distinct, the postmedian line not so oblique, somewhat broader and more faded, behind it at the costal margin 
as small whitish spot, the white apical spot larger and longer, the broad subterminal band receding more between 
4 and 7, the brown marginal shadow opposite it broader, reaching the subterminal band between 6 and 7. On 
the hindwing the two lines are nearer together, the interior one is stronger than the exterior one. $ type from 
Sao Paulo de Olivenpa, $ from C'hanchamayo (Peru) in the Berlin Museum. According to Schatjs a distinct 
new species. 
H. peruvex sp. n. (117 a) is near livex, larger, much more indistinctly marked, the antemedian line peruvex. 
broadly faded, vertical on the inner margin, in livex submedianly distally angular, inwards likewise bordered 
with whitish, the white in the cell extending to the large discal spot indistinctly coherent with the costal margin, 
the latter spot touching the broad faded postmedian line on vein 4; behind it especially at the costal margin 
a spot-like white brightening, also at the apex and behind the subterminal line. Hindwing as in livex, but the 
transverse lines more separated, the interior line crossing the discal spot. Under surface behind the straight 
postmedian line light, with distinct dark veins. Abdomen more olive yellowish-brown, not ochreous. Type: 
1 $ from Marcapata (Peru) in the Coll. Hopp-Charlottenburg. 
H. vialactea sp. n. (114 a) is very similar to the preceding species from which it is at once discernible vialaciea. 
by the light violettish-white median area enclosing the large intense oval discal spot; antemedian line not 
angular, but forming one bow each in the cell and submedianly, below 1 obliquely distad to the inner margin; 
marginal area as in fulviventris. Hindwing with a small discal spot touching the interior feebly curved line. 
Abdomen brown, only at the end more ochreous. Type: $ from the Chaco, La Paz (Bolivia), from an altitude 
of 3000 m, in the Coil. Stgr. (Berlin Museum.) 
H, orbifex Dyar. Thorax brownish-grey, abdomen thickly covered with ochreous hair, the brown orbifex. 
ground only showing through on the dorsum. Forewing exactly as in fulviventris. Hindwing with a large 
discal spot, the two lines far behind it, just as dark, but the exterior one much broader than the interior one. 
Expanse of wings: 38 mm. Rio de Janeiro. 
H. discifex sp. n. (114 a) is very near orbifex, but also similar to vindex. Abdomen brighter golden discifex. 
ochreous than in orbifex, wings blacker though not so black as in vindex: basal area darkened, the transverse 
stripes broad, somewhat hazy, convergent to the inner margin, behind the distal one at the costal margin a 
triangular light spot of the ground-colour, the subUrminal band, moreover, only separated by a very narrow, 
blurred line from the postmedian band which is distally less sharply defined. Hindwing with a large discal 
spot, the lines distantly separated, hazy, the interior one stronger than the exterior one. Type: 1 $ from Rio 
Grande do Sul in the Coll. Stgr. (Berlin Museum). 
H. maurex sp. n. (114 a) is an entirely sooty black species, the ventral side of the abdomen also black, maurex. 
the markings still deeper black, the transverse lines moderately broad, shaded, the posterior one passing over 
directly into the broad subterminal shadow. Hindwing with a discal spot and 2 lines, the interior line stronger, 
touching the spot. and $ from Passa Quatro, Sul de Minas (Southern Brazil); types in the Coll. Hopp- 
Charlottenburg. 
H. muscula Vuillot (114 a) is quite a different larger species which may be best ranged after maurex', muscula. 
it is also somewhat similar to Automeris violascens (114 g), but it does not fit to Automeris. Entirely black, 
thinly scaled, a little more densely in the basal half and the apical part of the costal margin, with a much 
produced apex of the forewing, a thick, deeper black discal spot and a very feebly marked postmedian shadow 
obliquely from the apex to the centre of the inner margin. Hindwing with a very faint discal ring-shadow. 
Abdomen beneath rusty red, above black. The $ is still more thinly scaled, diaphanous blackish-grey, the 
discal spot of the forewing much less developed. Abdomen beneath much darker, only feebly intermixed with 
rusty brown. Sa. Catharina. Larva on the 4 first rings yellowish-green, from the 4th ring on the ventrum 
and sides blackish-grey, from the 5th ring there are laterally large white, oval oblique spots bordered with deep 
black, from the 5th ring on the dorsum purple red saddle-spots with black longitudinal lines; ring-indentations 
yellowish-green, of the same colour the branched thorns.
