the c? from the corresponding sex of the same insect. Upperside : 

 the interspaces beyond the postdiscal oblique band on fore wing 

 and the cell and basal halves of the interspaces beyond the cell on 

 the hind wing distinctly tinged with yellow. Underside : all the 

 markings more neatly and clearly defined than in hierta, the inter- 

 spaces beyond the oblique postdiscal band on the fore wing bright 

 lemon-yellow. Antennae, head, thorax and abdomen in both sexes 

 as in D. kierta.

c? . Upperside : opaque white. Fore wing : costa and terminal 

 margin very narrowly black ; extreme base, apex broadly and 

 termen submarginally more or less thickly irrorated with black 

 scales, the width of this blackish border decreases posteriorly 

 along the termen. Hind wing : termen narrowly black, the black 

 markings of the underside show dusky bluish through transparency. 

 Underside, fore wingr : black ; an obliquely placed short broad bar 

 along the discocellulars and a subterminal series of outwardly 

 pointed spots, of which the anterior three lengthen into streaks, 

 white ; the anterior and posterior margins of the cell and broad 

 streaks, that do not reach the terminal margin, on each side of 

 veins 1 to 4, grey. Hind wing : rich chrome-yellow ; costa and 

 termen broadly black ; interspaces "1 to 7 with outwardly pointed, 

 broadly triangular, yellowish-white diffuse spots on the black ter- 

 minal margin, the black on the inner side of these spots produced 

 conically inwards ; the black in interspace 7 centred with an 

 elongate, outwardly somewhat diffuse, oval vermilion streak. 

 $ . Upperside : black. Fore wing : a broad oblique apical cell- 

 bar and a curved subterminal series of somew 7 hat hastate spots, 

 white. Hind wing : apical two-thirds of costa and the termen 

 broadly black, the rest of the wing yellowish white sparsely 

 irrorated with black scales ; the vermilion streak in interspace 8 on 

 the underside shows through by transparency, and the broad 

 terminal black border has a subterminal very obscurely marked 

 series of whitish spots. Underside: fore wing as in the rf but 

 the grey bordering restricted to very narrow streaks along the 

 median vein and veins 2 to 4. Hind wing : differs from that of 

 the J as follows : the rich chrome-yellow replaced by dull white 

 touched with yellow along the dorsal margin and in the cell and 

 lightly irrorated in cell and interspaces with black scales, the inner 

 margin of the black terminal border produced in the interspaces 

 into more elongate cones. In both sexes : antennae black, head, 

 thorax and abdomen above greyish ; beneath : white.
