several oblique zigzag dark lines; not only costa, but also termen is
suffused with pink. Posterior tibiae in erotias bear a brush of long
light grey hairs along the internal side, as was described with the
genus above. The females are very similar in the two species, but in
erotias the basal patch has a concave excision of the upper edge,
while the lower part of that edge is strongly rounded.

Type species: Phalaena Tinea salicella Linnaeus, 1758 (Europa).
This generic name has been reestablished by Heinrich (1926, in
Zeller 's emendated spelling) and is now accepted as Hedya by Obraztsov
(in. litt.) and Hannemann (1961) for several Palaearctic and
Nearctic species. Whether all these species are congeneric, seems
to be open to doubt, e.g., with regard to the Palaearctic Penthina
atropunctana Zetterstedt, and Nearctic Olethreutes separatana Kearfott
and Penthina cyanana Murtfeldt.
On the other hand, a characteristic group of tropical species,
hitherto indicated by generic name Platypeplus Walsingham, 1887,
and having rather uniform male genitalia, undoubtedly belongs
here; however, there are some minor differences which, to my present
knowledge, are constant. Therefore, I propose a division of the
entire group into three subgenera which maybe separated as follows:
1. Gnathos, a variably shaped, broad transverse band, strongly dilated in the
middle downwards and upwards, sometimes even becoming higher than
broad, lower edge simple; Spc2 present, sometimes small, shifted distad
(salicella), sometimes large, proximal and marginal, hindwing with veins 3
and 4 separate or connate .... Subgenus Hedya Hiibner, new status
Gnathos, a rather narrow, transverse band of a constant shape, with upper
edge straight and simple, lower edge forming two semioval finely denticulate
tumescences. Spc2 sometimes present 2
2. Outer edge of the base of cucuUus without modified large spines; females with
two small equal signa; hindwing with veins 3 and 4 usually connate.
Subgenus Platypeplus
Outer edge of the base of cucuUus with a row of very large, spindle-shaped
spines; females with a single large, curved and blunt signum; hindwing
with veins 3 and 4 stalked
