Drepanulides Motschulsky, 1866 : 192. Type-species Drepanulides palleolus Motschulsky, 



1866 : 193, by subsequent designation by Inoue, 1962 : 32. [Synonymized by Kirby, 



1892 : 730, by transference of type-species.] 

 Drepanula Gaede, 1914 : 65. Type-species Drepanula argyrobapta Gaede, 1914 : 65, by 



monotypy. [A junior homonym of Drepanula Frolich, 1828 : n.] 

 Drepanulina Gaede, 1927 : 287. Type-species Drepanula argyrobapta Gaede, 1914 : 65, by 



monotypy. [A replacement name for Drepanula Gaede, 1914 : 65]. [Synonymized by 



Watson, 1965 : 149.] 



This genus is distinguished from all other genera of Drepanidae, except Macrocilix 

 Butler and Tridrepana Swinhoe, by the presence of widely distributed brilliantly 

 lustrous scales on the upper surface of the wings. (In Tridrepana, one bright yellow 

 species, melliflua Warren, has similar lustrous scales on the wings. Macrocilix is 

 a distinctive genus in that the ground-colour of the wings of all the species is white) . 



Callidrepana includes over twenty species. It ranges from India to Japan, and 

 through the Malay Archipelago and New Guinea to the Solomons. Three African 

 species are known (see Watson, 1965 : 149). Four species occur in China : 

 hirayamai, pair ana, ovala and gemina (the latter two described here as new). (See 

 Table 1.) 



Key to the Chinese Species of CALLIDREPANA 

 Both Sexes 



Postmedial fascia on upper surface of both wings simple ; ground-colour very pale 

 yellowish white ; dark marking (where present) at distal end of cell on fore wing 

 small, ovate (PI. 12, figs. 370, 371). Genitalia as in Text-figs. 232-238 



gemina (p. 119) 



Postmedial fascia on upper surface of both wing double ; ground-colour buff or 

 buffish white ; marking (where present) at distal end of cell small and ovate, or large 

 and rectangular (PI. 12, fig. 372). Genitalia not as in gemina .... 2 



Upper surface of fore wing with large, dotted, rectangular marking at distal end of 



cell. (PI. 12, fig. 372). Genitalia as in Text-figs. 239-245 . hirayamai (p. 121) 



Upper surface of fore wing with small ovate marking at distal end of cell, or fore wing 



without cell-marking. Genitalia not as in hirayamai ..... 3 



Genitalia as in Text-figs. 221-227 ...... patrana (p. 114) 



Genitalia as in Text-figs. 228-231 ....... ovata (p. 117) 



Callidrepana patrana (Moore) 



(Text-figs. 221-227) 



Drepana patrana Moore, [1866] : 816. 



This species is separable from ovata, which is closely allied to patrana and forms a 

 superspecies with it, by the less elongate cell-marking (where present) on the fore 

 wing, the slightly more strongly falcate fore wing and by small but distinct differ- 

 ences in the genitalia of both sexes (see ovata). The male genitalia of argenteola 

 Moore (1858 : 369) (India, Burma, Formosa, Malaysia and Indonesia) indicate that 

 though this species is externally similar to patrana, except for the more strongly
