" Statura omnino proecedentis [ C/cem, Fabr.]. Alse antieae obscurce maculis aliquot disci nigris 

 punctisque quatuor aut quinqne minutis, hyalinis, subtus fuscte puuctis hyaliiiis. Posticre 

 rotundatae, hyalinse maculis disci atris, subtus pallidiores maculis aliquot nigris. Anteanae 

 uncinate." (Fahricius, I. c.) 



Occurs in Western China at Omei-shan, Cliia-ting-fii, and Chia-kou-ho. 



Except that they are rather larger, Chinese specimens are identical Avith 

 those from Sikkim and exhibit the same range of variation. The primaries 

 are sometimes traversed by a series of subdiaphanous white spots extending 

 from costa to inner margin. In a few specimens the black spots on 

 lower two thirds of submarginal area of secondaries are well separated 

 and clearly defined, but usually the spots are confluent and form a broad 

 submarginal band. 



Elwes says that the species occurs all along the Himalayas and is found in 

 Sikkim up to 4000 feet, from March to December. In the Malay Peninsula 

 it is represented by a form Avhich Butler has named calUgana (Trans. Linn. 

 Soc. (2), Zool. i. p. 556, pi. Ixix. fig. 11 ; Distant, Rhop. Malay, p. 387, 

 pi. xxxiv. fig. 6.)
