at the cell-end a dark strigiform spot; the dark subterminal shadow is indistinct and irregular. On the hindwing 
only the darker veins and a very feeble subterminal shadow are noticeable. The black 2 shows hardly any 
marking. Guatemala; Costa Rica. 
H. vittex sp. n. (113 c) is very similar to frigida, smaller, lighter yellowish-grey, the median area more 
distinctly prominent, brownish-grey, the interior border not straight but submedian, not on the median vein, 
inwardly projecting in a right angle, in the cell fused with the discal streak. Hindwing with a broad, straight 
dark median band. Body blackish, but very thickly covered with rusty yellow hairs, so that only the abdomen 
above shows through dark. Guatemala. According to 2 <$<$; type in the Coll. Hopp-Charlottenburg. 
HL pauper Dyar (113 c) has somewhat narrower wings than the preceding species, with a somewhat 
more produced and slightly falcate apex of the forewing; light drab, transverse lines very feebly whitish; a 
very conspicuous white spot in the cell before the slightly darker discal spot, and a whitish apical spot. Abdomen 
somewhat ochreous. Colombia; Peru. 
H, medifex Dogn. resembles frigida, but it is somewhat smaller, lighter drab, and distinguished by a 
very narrow lighter median band which is only 2 mm broad at the inner margin, 5 mm at the costal margin 
and contains a still darker discal spot; apical area down to vein 4 somewhat darkened. Hind wing in the 
marginal third somewhat lighter with a feeble indistinct discal streak and a subterminal band which is only 
visible in a certain exposure to light. Described according to a $ from Pacho (Colombia). 
H. terranea Schs., described only according to a $, is monotonously dark brown, scantily scaled, no 
markings except faint traces of a discal spot. Abdomen laterally with ochreous hair. Expanse of wings: 53 mm. 
Petropolis (Brazil). 
H. leilex Dyar is drab, shaded somewhat blackish, with fine darker veins, with a large round dark 
discal spot and small irregular shadowy spots instead of the subterminal line, the other transverse lines being 
absent. Expanse of wings: 40 mm. Peru. 
H. ascodex Dyar is similar to leilex but of a softer drab colour, without the blackish shading, on the 
forewing only with a large feeble discal spot and traces of the undulate-dentate distal border of the subterminal 
line. Hind wing with two feeble darker distal bands. Abdomen with ochreous hair. Expanse of wings: 
40 mm. Peru. 
H. metabus Cr. is said by Schaus to belong to this place; the insect is unknown to me, Cramer’s 
figure representing a brown $ without any markings is difficult to determine. Surinam. 
H athlia Dyar (113 c) has broader wings than the preceding species, the apex of the forewing is more 
rounded, the abdomen with brownish ochreous hair. Wings drab with a slight brownish tint and a broadly 
darkened discal spot; transverse lines broad, light, convergent to the inner margin, but the interior one more 
or less extinct, the marginal area behind the subterminal line somewhat lighter with a prominent whitish 
apical spot. Hindwing with a feeble dark cellular spot and only a light distal line which is slightly darker on 
both sides. Peru; Bolivia. 
H. individiosa Dyar is very similar to athlia, somewhat smaller, the apex of the forewing not rounded, 
the markings less distinct, the transverse line oft the hindwing straighter and nearer to the cell. Expanse of 
wings: 32—34 mm. Panama. 
H. valvex Dyar (113 c, d) is a larger species, with a blackish-brown front body, the abdomen with 
ochreous hair. Wings lilac grey with a sooty brown tint, basal area broadly darkened, the broad faded post- 
median band directly passes over into the subterminal band the discal border of which is almost straight; in the 
lighter median area a faded discal spot. Hindwing with a discal spot and 2 distantly separated postmedian 
shadowy lines. The $ is still more indistinctly marked. Guiana, Amazons. 
H„ umbratula Dyar (113 d). Head and thorax ochreous brown, abdomen lighter ochreous. Forewdng 
reddish lilac brown, transverse lines brown, both broad and uniform, the subterminal line undulate, irregular, 
narrow and extinct. On the hindwing the interior line is distinct, the exterior one faded, with a discal spot of 
medium intensity. Allied with valvex and umbrata Schs., but lighter and of a pink ground-colour instead of 
grey. Teapa (Tabasco, Mexico), Guatemala. 
H. latex sp. n. (113 d) may belong to this place. One female from Venezuela (Valencia) shows a marking 
similar to appnoximans-Q, but the wings are much broader, the apex is quite round, the costal margin of the 
hindwing much longer, the inner margin shorter than in approxitnans-Q. Ground-colour browmish-grey, with 
fine dark veins, basal area darkened, discal spot longer, but narrower than in approximans, the postmedian 
and subterminal bands forming a coherent broad dark area, below the costal margin turning rounded towards 
the base with its interior half, whilst the exterior half extends straight on towards the apex, so that a lighter 
triangular spot is enclosed. Discal spot of hindwing small, shortly behind it the whole subterminal and marginal 
area is darkened. Type in the Berlin Museum. A similar $ without denomination in the U.S. Museum of 
Washington. Another $ from Muzo, Colombia, in the Coll. Hopp-Charlottenburg.
