1897.] Indo- and Austro- Malayan Regions. 557 



Habitat: North Shan States and North Chin Hills, Upper Burma. 



Expanse: d 1 , TO inch. 



Description: Male. Upperside, both wings white. Forewing with 

 a broad basal black area which is reduced at the middle of the costa to 

 a fine line, and gives off a small black tooth at the end of the discoidal 

 cell ; the outer margin broadly but decreasingly black ; from the second 

 median nervule to the inner margin are two conjoined round black spots, 

 the upper the smaller, the lower joined posteriorly to the outer black 

 margin. Hindwing with a submarginal series of six round black spots 

 placed in pairs ; the outer margin narrowly black. Undekside, both 

 wings white. Forewing with an oblique basal black band which reaches 

 the costa at about its middle ; a submarginal series of conjoined round- 

 ed black spots, the series broken at the second median nervule, the 

 portion posterior to that veinlet being shifted well towards the base of 

 the wing ; the outer margin narrowly black, bearing an obscure very 

 fine macular white line. Hindwing with the base narrowly black ; the 

 three submarginal pairs of black spots as on the upperside ; the 

 margin narrowly black, including a series of small white spots. Cilia 

 black. 



Allied to G. roxus, Godart, differing therefrom (as figured by 

 Horsfield in Cat. Lep. Mus. E. I. Co., pi. ii, figs. 4, 4a (1828), from 

 Java), in having the white area on the upperside of the forewing 

 somewhat larger ; in the hindwing the white area is twice as extensive, 

 permitting the appearance of the three pairs of black spots near the 

 margin which in C. roxus are lost in the outer black area occupying 

 nearly half the surface ; on the hindwing on the underside there are 

 two black spots only in the middle of the submarginal series, in 

 C. roxus there are three ; and the marginal series of white spots on both 

 wings are far more prominent in G. roxus than in 0. roxana. Dr. O. 

 Staudinger in Iris, vol. ii, pp. 95, 96 (1889), has described " Lycazna " 

 roxus, var. angustior from Palawan in the Philippines ; L. roxus, var. 

 celebensis, from Celebes ; and L. roxus, var. cohserens from New Guinea, 

 Timor, and Wetter. None of these varieties agree with the present 

 form. 



Described from a single example kindly given to me by Major 

 F. B. Longe, R. E., w T hich was captured by the donor in the Kokang 

 State in the North Shan States on the Chinese frontier east of Bhamo, 

 at 5,500 feet elevation. Capt. E. Y. Watson possesses another speci- 

 men from the Upper Chindwin Valley in Upper Burma, taken in 

 March, 1893, and Colonel C. H. E. Adamson probably possesses a third 

 specimen from Burma taken at Aloungdan Kathapa, in the Lower 

 Chindwin District, in January.
