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 Obraz- 

 tsov (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 Kear- 

 fott 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 Cellifera, new subgenus 



Subgenus Hedya Hiibner, 1825, new status
