488 L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. [No. 3, 



Upper Burma, and by Colonel C. T. Bingham at the top of Mooleit 

 mountain and at a lower elevation in the Daunat Range, both 

 in Middle Tenasserim, Burma. The Burmese and Sumatran speci- 

 mens in our collection quite agree, and would probably be called 

 var. amarantha, Mitis, by the describer, who gives Darjiling as the 

 habitat of that form. In Sumatra it is very rare, occurring only at 

 Soengei Batoe and on the Central Plateau, Dr. Martin in thirteen 

 years collecting only obtained ten specimens, of which seven were 

 captured in June and July, and one each in January, March, and October. 

 All these specimens shew but little variation in colouring and markings. 

 The single female Dr. Martin possesses has the ground-colour slightly 

 lighter than in the male, more brown than black, the spots on both 

 wings are larger and more yellow, in the male they are whitish, and 

 the anal area is pale yellow instead of dark yellow as in the male. 

 Dr. Martin gives the expanse of his male specimens as 1*8 to 2'4, of 

 the female 23 inches, hence they average somewhat less than specimens 

 from the Eastern Himalayas. Since the above was in type I have seen 

 Heer P. C. T. Snellen's note on this species in Tijd. voor Ent., 

 vol. xxxviii, p. 26 (1895), in which he calls P. chrysorrhcea a small local 

 variety of P. belladonna. 



526. Delias glauce, Butler. 



Snellen as belisama. Hagen as belisama, and belisama, var. glauce. 

 Wallace as belisama. Staudinger as belisama. Kirby as belisama. 

 Grose Smith. The true D. belisama of Cramer, is, I believe, confined 

 to Java, while D. glauce takes its place in Borneo and Sumatra. It 

 is common on the Central Plateau round the Battak kampongs, where 

 it. frequents the red flowers of the "Datap" trees (Erythrina indica, 

 Lam.), according to Dr. Hagen. Dr. Martin has obtained a few 

 specimens also from Soengei Batoe and even from Bekantschan, where 

 they may perhaps have been cai'ried by one of the frequent heavy 

 storms that occur in the mountains. The female is very melanic iu its 

 colouring, as the white areas on the upperside of both wings in the 

 male are very greatly reduced in the female. It occurs most commonly 

 from May to July, but it flies in every month in the year. 



527. Delias hyparete, Linnaeus. 



Hagen. Wallace. Common over the whole of our area, even on 

 the Central Plateau, mostly in orchards near houses, as the species 

 of Viscum on which the larva feeds grows very frequently upon fruit- 

 trees, especially on Anonaceae. If flies throughout the year, but is most 

 abundant in May. The larva is yellow and hairy; the pupa is dark
