CHINESE DREPANINAE 127 



remain doubtful. However, an examination of the female genitalia and of external 

 characters such as the shape of the antennae, the wing shape, the colour-pattern and 

 the coloration has shown no great discordance between undulifera and the other 

 two species of Thymistadopsis except for the rather abbreviated colour-pattern of 

 the upper surface.

DEROCA Walker 



(PI. 12, fig. 375) 



Deroca Walker, 1855 : 822. Type-species Deroca hyalina Walker, 1855 : 823, by monotypy. 

 Deroca Walker ; Watson, 1957a : 129. [Revision.] 



Probably most closely allied to Callicilix Butler but distinguished from it by the 



colour-pattern and the lack of yellow coloration on the wings, differences in the 



male genitalia, and the presence of well-developed mid tibial spurs on the hind leg. 



Distribution. N. India, N. Burma, China, Formosa, Korea and Japan. (See 



Table I.) 



This genus has been revised by the present author (Watson, 1957a) and no 

 further material has been made available since this revision. The following list 

 includes the species and subspecies known to occur in China together with their 

 known distribution. (All four described species of Deroca occur in China.) 

 Deroca hyalina Walker, 1855 : 823. India, Burma, China. 



D. hyalina latizona Watson, 1957a : 134. China (Kwangtung, Szechwan, 

 Hunan, Kiangsi, Fukien, Chekiang). See Plate 12, fig. 375. 

 Deroca hidda Swinhoe, 1900 : 306. Sikkim, N. India, Burma, China. 

 D. hidda bifida Watson, 1957a : 137. X. India, China (N. Yunnan).

CALLICILIX Butler 



(PI. 12, figs. 376, 377 ; Text-figs. 251-257) 



Callicilix Butler, 1885 : 124. Type-species Callicilix abraxata Butler, 1885 : 124, by monotypy. 



Platypteryx nguldoe Oberthur, 1893, the only species subsequently added to 

 Callicilix, has been relegated to subspecific rank.
