This species rejiresents in the Snow Jloiintains J>. cuningputi Ribbe (1900) 

 from British New Guinea and ]>. ful/'f/inosits Keur. (1909) from the Arfak 

 Mountains. It is easily distinguished in both sexes by the forewing. 



<?. The basal area of the forewing, above, has the peculiar greyish tone of 

 D. cunhu/jjiiti, but reaches only to the j)oint of origin of M', more than half the 

 wing being black ; the black costal border (as in CHiiinyj/nti) does not invade the cell. 

 There are several exceedingly small white sulmjiical dots, and occasionally also 



feeble traces of dots at the euds of some veins. The black border of the hindwing 



is more sharply defined than in cxiungptifi ; measures nearly 10 mm. in front and 

 narrows to a point jmsteriorly. The white marginal spots are smaller than in 

 cuningputi. 



The underside resembles that of cuningputi, but the spots are deeper yellow ; 

 the one or two small spots placed distally from the cell of the forewing are 



yellow. The median band of the hindwing is anteriorly narrower than in 



cuningputi and posteriorly broader, and is so suffused with black in front of the 

 apex of the cell as to be nearly interrupted ; the yellow spots are smaller, the 

 snbmarginal ones being very thin transverse bars ; and the ground-colour has a 

 distinct purple tone. 



? . The upperside of the forewing is black for the greater part. The white 

 area, which has a yellowish tone, is so much suffused with black proximally that 

 it is reduced to a triangnlar patch extending from the hindmargin to the cell and 

 hardly reaching vein M' ; the black outer border measures 4 or i5 mm. at SM* ; in 

 some specimens the white patch is shaded all over with black and is more distinctly 



yellow. There is a snbapical curved row of four pale yellow dots. The hindwing 



has also a slight yellow tone. The black border gradually narrows to a point as in 

 the c? ; it is, however, as a rule narrower anteriorly than in that sex. 



The white area of the forewing beneath is less suifused with black than above 

 and is a little larger, there being also a spot in the cell ; there is a small yellowish 

 subcostal dot beyond the cell and a subapical row of five yellow spots, the margin 



moreover bearing some minute white dots. The hindwing resembles that of the 



i in the yellow spots being smaller than in cuningputi and the median band 

 reaching to the anal margin. The hind portion of this band is in $ and ? more 

 distal than in cuningputi. However, the band differs in some ? ? from that of 

 the S in being essentially broader, posteriorly much shaded witli yellow, and not 

 interrupted in front of the apex of the cell. 



A series of both sexes from Mount Goliath.

This form agrees closely with I), a. aroae Ribbe (1900), but the black outer 

 border of the forewing extends into the cell also on the upperside of the S, the 

 white cell-area being in both sexes much smaller than in the specimens from
