This species is a representative of Delias halieri Kenr., Ann. Mag. J. II. (S) 

 iv. p. 178. tab. 6. fig. 4 (1909), from the Arfak Mountains, and differs from it in 

 the much narrower black margins of both wings, in the forewing above bearing two 

 or three white subapical dots and the hindwing beneath having a red spot in the 

 cell along the median vein. Moreover, the black colour on the nnderside of the 

 hindwing is much less extended than in bakeii and the white central area and white 

 submarginal band are consequently much larger, the spots of the submarginal band 

 being in the S about as large as the yellow basal spot. 



The ? differs from the S in the greater extent of the black colour, but even 

 in this sex the black occupies less space than in the o" of bakcri. 



Length of forewing : 26 mm. 



A few specimens from Mount Goliath. 



4. Delias litis luctuosa subsp. nov. 



S. A siibspecie D. iltis iltis dicta alis auticis pro maxima parte nigris, posticis 

 late nigro marginatis distinguenda. 



The white area on the upperside of the forewing extends from the hindraargin 

 to M' and is much shaded with black in the cell. There is no white spot distally 

 to the apex of the cell, excepting three subapical dots ; the black border is 6 mm. 



broad at the hindmargin. The black margin of the hindwing moderately narrows 



behind, measuring .5 mm. in breadth at R^ ; its inner margin is diffuse. It bears 

 three white snbmarsrinal dots. 



On the underside the white area of the forewing reaches to the lower angle of 

 the cell and the base of R^ there being also a faint trace of a white mark beyond the 

 apex of the cell; the black border more strongly narrows posteriorly than above; 



the yellow snha[iical band is slightly broader tlian in D. iltis. The central area 



of the hindwing is more uniformly suffused with sulphur-yellow than in D. iltis, 

 the red line is thinner and the white spots placed at its outer side are smaller and 

 more triangular, and the black marginal spots consequently larger. 



Length of fort- wing : 29 mm. 



One cJ from Mount Grooiue, situated at the boundary between German and 

 Brifi>h New Guinea, elevation 11,000 ft. ; sent by A. S. Meek, who received the 

 specimen from a friend. 



5. Delias weiskei leucias subsp. nov.

 a costa ad marginatu abdominalem albo margiuata distinguenda. 



The inner edge of the black borders to the upperside of both wings is more 

 sharply defined tliaii iu the [iriority form, the white scaling scarcely invading 

 the bbick ; the borders, moreover, are visibly narrower, and that of the forewing 

 has centrally a straight inner edge. The red discal line of the hindwing beneath
