Habitat. — Upper and Lower Burma ; Tenasserim ; Siam ; Malay Peninsula. 



DiSTEiBUTiON. — The type specimens of this race were taken at " Hatseiga, 

 Houngduran, and Naththoung, Upper Tenasserim" (P. Z. S. 1878, 840). Signer 

 L. Fea obtained it at " Bhamo, Upper Burma, in November, and at Malawoou, 

 Lower Tenasserim, in August." Col. C. H. B. Adamson records it, as Panope, " a 

 very common insect in Burma, from May to October, and very variable in the 

 amount of white markings on both wings. It occurs wherever dissimilis is found " 

 (List 1897, 49). Capt. E. Y. Watson found it " common at Rangoon and Beeling " 

 (J. Bombay N. H. S. 1882, 20). Mr. F. B. Dempster took it during the Chin- 

 Lushai Expedition of 1889-90 at Laivar and Launghut, in March " {Id. 1890, 387). 

 Capt. E. Y. Watson records "two specimens taken at Tilin, in March, durino- the 

 same Expedition" {id. 1891, 54), and also found it " common in the Chin Hills and 

 the Upper Chindwin, from March to June, but not found above 3,000 feet elevation. 

 These also include the dissimilis form " (/(/. 1897, 672). Mr. H. J. Blwes records 

 " several males from Tavoy, Pousekai, and the Hills on the Siamese frontier " 

 (J. As. Soc. Beng. 1886, 433).
