Inoue (1962 : 21, 22) recently transferred to a new genus, Palaeodrepana (p. 92), 

 three species previously classified under Drepana, and it is clear that further re- 

 classification of Drepana, sensu Gaede (1931), is necessary. I consider, however, 

 that the four Chinese species dealt with in the following account are congeneric 

 with the type-species of Drepana. Several species included in Drepana by Gaede 

 (1931) have been transferred in this paper to other genera (see index). 



There are overall similarities between Drepana and Tridrepana Swinhoe (p. 11 1) 

 which suggest possible close phyletic affinities.

This species is closely allied to Drepana falcataria L. (1758 : 519) and is known 

 to be capable of forming hybrids with the latter (see Strand, 1911 : 199). It can 

 be distinguished from falcataria by the colour-pattern and by minor differences in 

 the male genitalia.

The nominate subspecies has been recorded from most European countries. It 

 can be distinguished from acuta by the colour-pattern of the wings.
