single specimen of the clrj-sea son form {Watson!) at the foot of the Chin Hills, in 

 March" [I.e. 669). Mr. 0. Limborg records taking Watsoni o\\ the road from 

 " Monlmein to Meetan, and at Honngduran, Upper Tenasserim " (P. Z. S. 1878, 839). 

 Dr. N. Manders writes, " I have specimens of Thestylis from Fort Stedman and 

 Bernardmyo, Shan States. The females are mimics of Delias Belladonna. T have 

 not taken Watsoni in the Shan States, and but rarely in Karenee " (Tr. Ent. Soc. 

 1890, 533). We possess both sexes of Thestylis from Sikkim, males from the Khasias ; 

 Manipur ; Upper Tenasserim taken by Col. C. T. Bingham in April ; Upper Mekong, 

 Shan States, taken by Mr. J. Roberts, C.E, ; and of Watsoni, males from Sikkim, 

 Silhet, Monlmein, and Upper Mekong.
