H. cotto Dyar (156 h). Forewing broadly triangular with a strongly developed dent in the centre 
of the inner margin and at the anal angle; forewing light purple brown with a bronze shadow in the lower 
half of the median area and from behind the cell to the anal angle, the undulate line is marked by a less 
distinct similar shadow; transverse lines fine, blackish, the interior one twice notched, the exterior one finely 
dentate; a distinct round black spot at the cell-end. Hind wing brown, lighter towards the base, with a brown 
but not contrasting stigma. Mexico. 
H. punctilla Sells. (156 h). Forewing light reddish brown with black, undulate-dentate transverse lines, 
the exterior one more distinct at the costal and inner margins; a red-brown spot at the cell-end with a 
smaller black one above it. Hindwing white, veins and margin reddish-brown, with a small red-brown stigma. 
Expanse of wings: 40 mm. Venezuela. 
H. pagana Schs. has reddish-brown forewings finely strewn with dark grey especially in the median 
area, with a large black cell-end spot and quite indistinct transverse lines, the exterior one punctiform, small 
dark apical shadowy spots behind it. Hindwing white, veins and margin brownish, with a very much con¬ 
trasting stigma. Expanse of wings: 45 mm. Paraguay. 
H. alba WJcr. (156 h). Forewing very light greyish-white, strewn somewhat darker, with very indistinct 
punctiform transverse lines, without a discal spot. Inner margin with a broadly triangular dent, without an 
excision. Hindwing white with a fine brown marginal line and veins, and an ablong reddish-brown stigma. 
Abdomen also reddish-brown. Mexico. 
H. nigrescens Schs. (= obliquiplaga Dyar) (156 i). Forewing violettish-black with a brown distal 
margin, mixed with a somewhat reddish-brown colour at the base, with a dark oblique shadow from the cell 
to the distal margin; transverse lines dark red-brown, some whitish scales behind the exterior line at the 
apex. Inner margin deeply cut out before the anal angle. Hindwing dark brown. Costa Rica. 
H. imitans sp. n. (157 c) is similar to nigricosta, but easily discernible from it by diaphanous white, 
somewhat opalescent hindwings with a narrow light brown margin and veins. Fore wing duller brown, median 
area without a lilac shine; costal margin only very narrowly blackened, the undulate line without any white 
at the costal and inner margins, marked here as very faint grey shadows. 1 $ from the Rio Songo (Bolivia) 
in the Berlin Museum. 
H. nigricosta Schs. (156 i). Forewing red-brown, a slight violet shine in the median area, with a 
broad black costal margin strewn with white, with dark transverse lines, the exterior one dentate, marked 
on the veins by dots; the undulate line is marked by a few white scales apically and above the anal angle; 
an oblique dark line at the cell-end, and a dark shadowy spot below the centre of the margin. Hindwing 
dull brown. Expanse of wings: 53 mm. Costa Rica. 
H. phocas Schs. is near nigricosta from which it is separated by the different shape of the wings. 
Forewing brownish violet, dull violet at the costal margin strewn with bluish-white; anterior transverse line 
chestnut-brown with a white dot on vein 1; an oblique streak at the cross-vein; postmedian line punctiform, 
connected by a fine dentate line, shaded brownish outside above the inner margin; an oblique brown shadow 
in the centre of the margin. Hindwing whitish with a browner inner margin, veins and stigma. Expanse 
of wings: 40 mm. Amazons. 
H. praxides Schs. differs from phocas in the white hindwing and has the same wing-contours as the 
following eustalhia. Anterior body cinnamon-red. forewing more reddish-brown with a dark grey costal margin 
strewn somewhat white, and a fine dark basal line; the fine brown antemedian line extends almost straightlv 
to the inner margin, an oblique streak at the cross-vein; the postmedian line proceeds from before the apex, 
undulate-dentate, below 6 only as black and white vein-dots; a cinnamon-brown oblique shadow between 5 
and 3, and a blackish-brown oblique subterminal shadow between 8 and 5. Hindwing white with a narrow 
cinnamon-brown margin and stigma. Expanse of wings: 42 mm. Brazil (Rio Purus). 
H. eustalhia Schs. Anterior body reddish cinnamon. Forewing with a straight costal margin, a pointed 
apex, margin and anal angle in an oblique rounding as far as the base of the inner margin, reddish-brown, 
with an iron-grey costal margin and a mouse-coloured basal area, of the same colour is the median area 
bordered inside by the dark grey antemedian line, outside by an oval grey cell-end spot, and between 3 and 
the inner margin by the undulate postmedian line which is extinct between 3 and 5; instead of it there is an 
oblique cinnamon-brown shadow; an irregular grey subterminal shadow between the costal margin and 6. and 
a small spot before the anal angle. Hindwing white, inner margin sand-coloured grey, veins and margin 
narrowly cinnamon-brown, stigma deep brown. Expanse of wings: 45 mm. Brazil (Rio Purus). 
H. singula Guen. (156 i) is a very large brownish violettish-black species, very finely strewn grey, 
with dark dentate transverse lines and still deeper shadowy spots, one in the cell-end and one separated from 
it, extending to the anal angle. Hindwing greyish-brown. Mexico to Costa Rica. 
H. violascens Guen. (= singuloides Dyar ) (156 i) is very similar to singula, but the hindwing is more 
whitish, greyish-brown only on the veins, and the marginal shadow of the forewing is confluent in a line 
with the cellular shadow; transverse lines less distinct. Colombia to Brazil.
