that in the palaearctic species amasinus-Q *) or varius. Ground-colour light smoke-brown or greyish brown, 
but not so transparent as in luteicornis. The broad light fringe speckled dark. 7 or 8 tiny oval round spots 
before the lighter places in the margin. Behind them a long narrow silvery white transverse band beginning 
2 mm below the apex and terminating at the 1st median branch, almost parallel with the distal margin. Di- 
stally bordered by a slightly undulating dark transverse line, inwardly by a twice as broad dark band. The 
latter is followed by a light greyish brown transverse line which is partly bordered with dark inwardly and 
behind which, especially upward and downward, there is an irregular whitish line bordered with dark. At the 
2nd median branch, this white line unites semicircularly with a short whitish linear marking extending to the 
lower part of the discal cell. 2 or 3 tiny oval dark spots below the costal margin, about 6—8 mm distant 
from the apex; somewhat farther inward, below between veins 7 and 8, there is a short white longitudinal 
streak pierced by dark; below the basal half of the costal margin in the upper part of the discal cell which is 
long here, there is a long whitish longitudinal streak bordered with dark above; a similar one seems to have been 
before the inner margin above the submedian vein. This part of the wing is unfortunately rubbed off, but it has 
contained larger dark patches, on the left forewing one notices yet that the basal part between the median 
vein and the median branch was filled with dark. On the dark smoke-brown under surface of the forewing 
only the white distal-marginal band shows feebly through; fringe less speckled dark, only the extreme tips 
remain light. Hindwing dingy greyish brown, somewhat lighter on the inner-marginal part, irregular lighter 
places are hardly discernible; fringe very feebly speckled dark in the middle. Hair of thorax dark olive brown, 
vertex lighter grey. The short slightly serrated antennae dark brown, the thin dark palpi, 1 ]/ 2 mm long, hang 
downward. Legs hairy, olive brownish grey; tarsi and abdomen more violettish grey. 
H. dimidiatus Berg. Description according to Berg. This species of which only 1^ is at hand, collect- dimidiatus. 
ed in Conception (Chile) on the 26th of February 1879, is easily recognizable by the yellow middle part of the 
fore wing somewhat forming a longitudinal band; the costal third and the middle basal part of the inner margin 
is of a dark brownish grey strewn with a few dark dots. Head, palpi, anterior part of thorax, and the costal 
third of the inner margin, the marginal dots of the forewing as well as the legs brownish grey. Length of fore¬ 
wing: 42, of hindwing: 35nnn. Chile. 
The following species are from the neotropical part of America: 
H. helga Schs. Body and forewing pinkish reddish yellow, with very fine dark rings and lines in helya. 
the marginal third and at the inner margin. Hindwing salmon-coloured, more pink at the margin. Broad olive 
grey lines at the veins near the margin are connected by similar shadows. 56 mm. According to 1 $ from 
Sa. Catharina. 
H. munona Schs. Thorax cinnamon red, abdomen paler. Forewing ochreous orange, paler at the margin, munona. 
Costal margin narrowly dark brown, with brownish spots, not extending to the cell, a few spots also at the 
inner margin. Slightly darker from the base of the cell to the middle of the inner margin, pinkish brown below 
it. Hindwing pale orange. 35 mm. 1 $ from Sa. Catharina. 
H. paropus Drc. Forewing yellowish fawn-coloured. Costal margin slightly shaded with yellow, head, paropus. 
thorax, abdomen and legs yellowish fawn-coloured. Antennae dark brown. About 44 mm. Ecuador (Sarayacu). 
H. pharus Drc. (185 a). From Guatemala, Las Mercedes (3000 ft.) and Duenas (Champion); Costa Rica, pharus. 
Irazzu 6'—7000 ft.); the figure according to a specimen from Las Mercedes, somewhat darker than the others; 
the specimen from Costa Rica is much paler; that from Duenas is intermediary. Forewing dark brown, spotted 
lighter. A large brown spot below the cell-end. Behind it an exterior and submarginal dark brown band. One 
short silvery streak each in the base of the cell, at its end near the apex. Hindwing darker, with reddish 
brown hair at the base and inner margin. 56 mm. 
H. pretiosus H.-Schdff. (185 a). Thorax olive brown, abdomen lighter, forewing rather variegated, pretiosus. 
Yellowish brown at the base at the costal margin and inner margin. Of the same colour is the V-shaped band 
from 2 / 5 costal margin to % inner margin and from there again to 2/ 3 costal margin. Beginning from the base of 
the costal margin, the band is set with small red spots. Greenish before it in the cell and behind it at the 
distal margin. Dark brown at the middle of the inner margin and spot-like between the sides of the V-shaped 
band. Hindwing pale yellow, rusty yellow at the margin. $ 52 mm. Brazil. 
b) Phy m a t o p u s Wllgr. 
A circumpolar group represented in the palaearctic region by ganna and macilentus with subordinate 
forms. Forewing brown with white bands, of an Arctiid-like habitus. 
Ph. hyperboreus Mschlr. (= pulcher Grt.). Shape and size of ganna which it resembles so much that hyperboreus. 
some American authors formerly considered all the hyperboreus to be forms of ganna. Forewing pale brownish 
with a salmon-coloured tinge on the forewing; easily discernible from the form mcglashani (99 a) by the light 
angular band being interrupted several times and the other light marking being also broken up into smaller
