Forewinga: pale grey, strongly sprinkled with orange and lilaek scales, giving a decided olive tinge. An indistinct stigma on the discoccllulars, from which a faint dark streak rnns into the cell. Across the disc of the wing runs an indistinct zigzag transverse line, from which horizontally proceed two dark lines abont 5 mm. long between veins 2 and 4. Hindwimji : black, crossed by two bauds of pearl-grey 3 mm. wide; onter margin snffnsed Nvith grey scales ; fringe creamy white. Urulersidp, : as above, bnt more imiform grey. Head and thorax like npperside of forewing ; abdomen dark grey, with five lilack and five light grey lateral spots placed alternately; underside of :i,l)doiiic'n whitish grey, with a median row of small black dashes.

Closely allied to D. hijpothous and magnifica, but easily distinguished from botii by the very differently shaped discal dark green area. The basal edge of this patch is straight; the outer edge' is deeply sinuate between veins 4 and 5, this sinus filled up with white ; in front of the sinns the patch measures only 7 mm. in width, and between veins 2 and 3 only 2 mm. The pale line situated between the dark green patch and the apex of the wing is very strongly curved between veins 4 and 5, the line reaching vein 4 at a distance of 7 mm. from the outer margin ; the space between this line and the discal patch is partly scaled white, especially close to the dark green patch. The cellule between veins 3 and 4 is, in /i>/pot/ious and DKKinifica, olive-green or dark green, except a trapezoidal submarginal sjiot of fawn-colonr; \\\ <loherti)i^\m latter spot is much enlarged and almost ecru-drab. Hind-wing more reddish than in the allied species. Unclcrsidi' : as in In/potlious, the three discal brown lines of the forewing more ]iromini'nt ; hindwing with two white dots at costal margin.
