New Forms of Butterflies from Bunt 511 



Length of fore wing : <? $ , 30 mm. 



Habitat. — Buru, Koentoeroen, 3,500 feet, April, two $ $ , four 2 ? . 



This species is apparently allied to stressmanni Eoths., from Ceram. 



6. Delias vidua J. and T. S (pi. VII, figs. 7, 8). 



$ . Upperside white. Fore wing with broad black apical area 

 and costa narrowly black. Hind wing with broad black distal area, 

 in cellules 2 and 3 with indistinct triangular prolongations. The 

 black dusting along the edge of the white area is more uniform but 

 less strongly present than in isse echo. Underside with fuscous black 

 ground-colour. Fore wing with apical area somewhat as in echo but 

 broader ; proximal area pale yellow, paler still posteriorly. Five small 

 submarginal spots in 3, 4, 5, 6 and 8, the two anterior ones the larger. 

 Hind wing with a submarginal series of six yellow spots, the one in 

 6 the larger, the others uniform and somewhat linear. Base to near 

 middle of cell and cellule 8 dusted with yellow, inner margin yellow. 



Length of fore wing : 33 mm. 



Habitat. — West Buru, River Pohatiga, 3,000 feet, April, a single 

 3 only. 



Now that we have the S of this curious form, closely resembling 

 ■isse echo Wall, in both sexes, we may venture to regard it as a relative 

 of caliban Sm., British New Guinea. 



Family NYMPHALIDAE. 



7. Dichorragia ninus Feld., buruensis subsp. nov. 



<y % . Upperside of fore wing with spots better defined and slightly 

 larger. Ground-colour darker-green. Hind wing darker than in ninus, 

 the green markings replaced by blue and larger in the $ , in the % 

 smaller, but owing to increase in size of the white patches. Black 

 marginal border narrower. Underside of fore wing with spots dis- 

 tinctly larger than in ninus. Hind wing with blue discal spots more 

 prominent, the white patches larger, and the black ocelli more strongly 

 edged with lilac distally. 



Habitat.— West Buru ; En Beloro, 1,670 feet, March, 3 $ ; Kako 

 Tagalago, 2,700 feet, May, one ? .
