H. falciiera Him. (= myops Wkr.) (114 b). Wings more falciform; brownish, rather variable; the falciferu. 
interior transverse line more or less distinct, acute-angular below the costal margin and here sometimes bordered 
with whitish, the posterior line very distinct, dull brown, at the costal and inner margins somewhat triangularly 
thickened, almost straight, only below the costal margin slightly flawed; discal spot elongate, subterminal 
shadow very faint; in the shading of the upper marginal half a more or less distinct whitish spot. Hindwing 
in the inner marginal half mostly somewhat blackened, behind the exterior transverse line the margin is 
somewhat lighter. Brazil. . 
H. obtusa Dogn . is a small species characterized by the obtuse apex and straight distal margin of the obtum. 
forewing. Front body brown, abdomen rusty yellow. Wings drab, with 2 darker lines, a straight postmedian 
line being broad on the forewing and running parallel to the margin, and a subterminal line being likewise 
parallel, but only complete on the hindwing, on the forewing only marked at the costal margin; discal spots 
scarcely visible; forewing with traces of a lighter marginal line proximally bordering on the darker margin 
from the apex to 3. Described according to a with an expanse of 32 mm, from Obidos (Amazons). 
H. pallidex Dogn., likewise based upon but 1 $ from Uruguay, is light grey, the thorax somewhat i wlUdex. 
darker, frons, collar and abdomen ochreous. Forewing light grey, apicad somewhat darker, the apex itself 
with a small light spot, with 2 fine dark transverse lines w'hich are only 1 mm distant from each other at the 
inner margin, but 8 mm at the costal margin, thus almost forming a V; between them a thick dark, discal spot; 
subterminal shadow intense, disappearing towards the costal margin. On the similarly coloured hindwing the 
lines are hardly indicated, beneath much more distinct, the exterior line is a broad band. Expanse of wings: 
35 mm. 
H. croex Schs. (114 c). Head and thorax dark grey, abdomen above brownish yellow, beneath grey, croiix. 
Wings thinly scaled, dull grey, the hardly discernible lines on the averted sides whitish, the posterior line at 
the costal margin broader; apically a feeble light shadow; a very feeble subterminal brightening; discal spot 
feeble, shaded. On the hindwing the margin is somewhat lighter behind the subterminal band; the small discal 
spot is feeble. Guatemala. 
H, colombex Dogn. (114 c) is somewhat larger than the preceding species and not quite so thinly scaled, colomhex. 
the lines are only a very indistinct whitish brightening, a scarcely darker median area encloses the shadowy 
discal spot: subterminal band very indistinct, touching the postmedian line between 4 and 6. Hind wing with 
a feeble discal streak and 2 quite indistinct lines. San Antonio (Colombia). It also resembles inficita in which, 
however, the more oblique postmedian line is more remote from the apex at the costal margin, the hindwing 
being without any lines. 
H. tinturex Schs. (114 c) likewise resembles the two preceding species, but the ground colour is more linlurex. 
of a dull pinkish lilac, the very faint antemedian line is whitish, the postmedian line broad and fadedly darker, 
the subterminal area with hardly any marking. Hindwing with a broader median shadow and a narrow sub¬ 
terminal line. Guatemala. 
H. humilis Dogn. (114 b) may be only the Amazons-race of colomhex, somewhat smaller than the latter, humUis. 
the abdomen lighter yellowish, greyer, the transverse lines at the costal margin bordered with a more whitish 
shade. Sao Paulo de 01iven9a (Amazons). 
H. inficita Wkr., as mentioned above, is said to be very similar to colombex, but the postmedian line is inficita. 
more remote from the apex at the costal margin, more oblique and soon ends below the costal margin; the 
marginal line is also farther away from the distal margin. Hindwing without any lines. Brazil; Costa Rica (?). 
H„ alinda Drc. (1 14 c) is a more slender species with a produced falciform apex, the ground colour most alinda. 
variable from an almost pure pink with all tints to brownish or lilac grey, the transverse lines broad, somewhat 
faded, on the averted sides mostly somewhat lighter, with an obsolete discal spot and a more or less distinct 
subterminal band. Hindwing with 2 faint transverse lines. Guatemala, Costa Rica. — colombiana Dogn. colombiana. 
(114 d) is larger and more contrasting, the postmedian line straighter, otherwise coloured and marked the same. 
From Costa Rica to Eastern Colombia. - pernex /. n. (114 d). In Western Colombia the species is represented perne.v. 
by a still more slender form with a still more produced apex of the forevdng and a higher shape of wings owing 
to the longer distal margin. Almost of a pink flesh colour, the two transverse lines more parallel, therefore 
the median area at the inner margin much broader, the subterminal band narrower, the light apical spot long 
and distinct. Hindwing more triangular, the transverse lines nearer together and straight. Type: 1 q from 
Bella Vista (Western Colombia) in the Coll. Niepklt. 
H. zonex sp. n. (114 d) is allied to alinda, fore wing narrower with a more produced apex, hindwing zonex. 
almost triangular, with an acute-angular anal angle and a straight distal margin; ground colour light violettish- 
grey, strewn with white, especially basad, at the costal margin and anal angle; the two transverse lines close 
together, forming a narrowly triangular dark median band which encloses the faded discal spot; subterminal 
and marginal markings the same as in alinda colombiana. Hindwing more blackish, behind the indistinct distal 
transverse line lighter reddish, with a faint discal streak. Abdomen with ochreous hair and blackish bands. 
Legs not pink. Colombia. Type: 1 $ in the Coll. Hopp-Charlottenburg, from Icononzo (Pandi).
