D. extatura Dist. Body grey, tibiae and tarsi ochreous. Fore wing greyish-brown with 4 dark transverse extatura. 
lines. The antemedian line is almost straight, the postmedian line undulate and distally convex. Between the 
subbasal line and antemedian line some groups of black scales, between the 2nd and 3rd transverse lines a 
ring-macula in the cell, between the 3rd and 4th transverse lines a dark streak at the costal margin. Hindwing 
pale creamy white with a dark spot at the apex. $ more intensely clouded black, particularly at the base and 
around the 3rd transverse line. Hindwing with traces of a dark sub marginal band. Expanse: 35 to 43 mm. 
Transvaal. 
D. pseudosatanas sp. n. (25 b). Markings as in satanas, but ground-colour of forewing red-brown, pseudosa- 
below 1 c before the antemedian line a dark spot, the subterminal line irregularly undulate, hindwing of a 
somewhat yellowish tint. Wings shorter. type from Bosum, Uam District, in the Berlin Museum. 
D. poliotis Hmps. Forewing white, thickly powdered with brown, veins brown. Antemedian line : poliotis. 
slightly undulate. At the cell-end a brown triangular spot at the cross-vein. A brown line from the origin 
of vein 2 to the hincl-margin, below vein 2 distally angled. Traces of a transverse line from the costal margin 
beyond the cell to the posterior margin of the cell. Postmedian line hazy, brown. Traces of a subterminal row 
of spots, and a row of black dots directly before the margin, a fine dark terminal line. Hindwing white. 
Expanse: 54 mm. Abdomen white, dorsally pale reddish-brown, on the sides yellowish. Transvaal. 
D. pyrosoma Hmps. Head and thorax white; tegulae, upper portion of patagia, anterior femora and pyrosoma. 
tibiae yellow. Abdomen white, basal segment with a red dorsal tuft, segments 2 to 6 scarlet with a white 
median line and white posterior margins. Anal end white. Forewing silvery white, antemedian line yellowish 
like the spot at the cross-vein. Terminal area with 4 feebly curved yellow transverse lines. $ with more 
numerous and more distinct transverse lines. Expanse: 52 mm. Transvaal. 
D. confinis Dist. Body chalky white, % of abdomen ochreous-yellow, posterior margins of the three confinis. 
basal segments black, two black spots before the end. Wings white, transverse lines of forewing, if present, 
yellowish, not dark. Expanse: 46 mm. Transvaal. 
D. octophora Hmps. Body white, with black spots; abdomen ochreous yellow with blackish dorsal octophora. 
and lateral stripes. Forewing white, costal margin at the base black. Subbasal line black, angular, a double 
dentate antemedian line, the second of which proceeds from a ring at the costal margin. A ring in the centre 
of the cell, macula at the cell-end 8-shapecl. A stripe proceeding from the centre of the costal margin and a 
Y-shaped marking at the hind-margin. Postmedian line irregularly dentate, strongly bent. A black streak 
at the costal margin with a white dot in it before the apex; a submarginal irregular row of dots, a terminal 
row of black dots, growing larger and triangular towards the tornus. Hindwing white, some dark spots at and 
below the apex; traces of a submarginal line, a terminal row of black streaks. Expanse: 38 mm. South Africa. 
D. bryophilina Hmps. Allied to D. octophora-, body yellowish-white with black spots. Abdomen white, bryophili- 
powderecl with blackish. Forewing yellowish-white. Subbasal line black with a short streak branching off na - 
below the costal margin. Antemedian area with thin black streaks above the hind-margin. Antemedian line 
very much angled black. A black spot at the hind-margin unites the antemedian, median, and postmedian 
lines. A round black spot in the centre of the cell, a macula surrounded with black at the cell-end. Median 
and postmedian lines black. A black spot at the costal margin before the apex, indistinct subterminal vein- 
streaks, a slanting black spot at the tornus. Terminal line black. Hindwing white, powdered with blackish, 
marginal area darker. The spot at the cross-vein and a series of dots and streaks at the margin black. Expanse: 
32 mm. South Africa. 
The following species chiefly described by Holland are often not determi¬ 
nable:; they may often have been wrongly ranged. 
D. clathrata Holt. (25 a) is easily recognised by the claret-coloured forewing with 2 straight vertical clafhrata. 
whitish transverse lines proximally bordered with dark. Costal margin narrow, distal margin broader dark. 
Hindwing varying from light reddish to yellowish. Expanse: 25 to 30 mm. Ogove. Ivory Coast. 
D. argiloides IIoil. (25 b). Body greyish-white, basal third and distal margin powdered with blackish, argiloides. 
2 or 3 black spots at the cross-vein and some black spots on the otherwise yellowish fringe. Hindwing white, 
at the anal angle blackish. Under surface purely white, only the costal margin is brown, and the spots on 
the fringe are black. Gabun. 
D. arctioides Holl. is doubtfully placed to this genus. Body ochreous yellow, abdomen white, at arctioides. 
the end greyish. Forewing pale ochreous, base of discal cell whitish; numerous red-brown lines form a reticular 
marking; in the middle they are denser and form a transverse band. At the distal margin below the apex and 
at the anal angle a dark nebulous spot. Hindwing purely yellowish-white. Expanse: 30 mm. Ogove. 
D. apateloides Holl. is doubtfully ranged here. Body pale grey, abdomen beneath white. Forewing apateloides. 
greyish-white; cross-vein with a narrow streak of erect black scales. Behind it a transverse line of erect white 
scales, distally bordered with dark brown. A submarginal row of dark crescents is proximally bordered with 
white. Margin with black internerval spots, proximally sagittiformly bordered with white. Fringe whitish.
