larger and deeper red, and have only a trace of a yellowish white border here and 

 there, the black area in which they are situated more sharply defined. 



? . Upperside less yellowish than in isabellae ; the black discai area of the 

 forewing larger and more sharply defined, that of the hindwing being also more 

 extended and more prominent, reaching from C to M- or beyond ; the submargiual 

 patches of the hindwing of about the same size as in isabellae, i.e. smaller than 

 in schoenbergi, the fifth separated from the yellowish grey basi-discal area, the sixth 



also more or less distinct. On the underaide, the forewing is similar to that 



of isabellae, bnt the hindwing presents the same differences as the i in the red 

 patches and the black area.

S. i'pperside, forewing : a snbapical row of four white patches separated from 

 the disc by a blackish shadowy band which is accentuated by black vein-streaks, 

 a fifth spot not isolated ; the black apical and distal border sharply dentate upon 



the veins, very thin between M' and W, disappearing behind M-. Hindwing : 



black marginal border about 2 mm. wide between the veins, dentate upon the 

 veins ; a series of submarginal patches tinged slightly with red, separated 

 from one another, but merged together with the basi-discal area, except the 

 second and third patches, which are more or less bordered with black scaling 

 proximal ly. 



Underside : forewing white ; costal margin black, continnous with an obliijuely 

 transverse band which crosses the wing be3"ond the apex of the cell, isolating a 



row of five white submarginal patches. Hindwing : yellow from base to disc, this 



area excised between SC^ and R^ where the disc is white, the yellow area more 

 or less bordered with white also between R' and SM* ; six orange submarginal 

 patches, partly bordered with white, especially the second, and followed by a double 

 seventh spot which is smaller and white tinged with orange ; proximally of these 

 patches a black band of nearly even width extending from tlie costal to near the 

 abdominal margin, somewhat lunulate between R^ and SM-, curved basad at SC- 

 and produced basad behind this vein, the projection being more or less vestigial 

 to base of wing ; black margin thin, widest at the veins, measuring here about 

 2 mm. 



? . Upperside dull black, grey between the veins from base to apex of cell, the 

 grey area extending more distad between cell and abdominal margin ; a small white 

 dot on cross-vein ; a submarginal row of spots on each wing, the spots much smaller 

 than in D. schoenbergi. 



Underside. Forewing : the black area more extended than in c?, reaching 



to M'', where it is about 6 mm. broad ; basi-discal area yellow, shading into white 



posteriorly ; subapical spots rather smaller than in S . Hindwing : black band 



situated j)roximally of orange spots somewhat broader than in S , with very little 

 white scaling between it and yellow basi-discal area ; black discai margin wider 

 than in cf .
