patagia and mesothorax black streaks; neck-ring carmine; abdomen carmine with a black dorsal line and rows of 
black spots on the sides and beneath. Forewing olive-yellow with very much curved black transverse lines 
and spots; fringes whitish. Hindwing carmine, a discoidal moon-spot, a curved median band from the costa 
to vein 1, an angled, curved postmedian band and a submarginal band as far as the submedian- fold, as well 
as an anal-angular spot black. The $ is dimorphous, one form being exactly like the <$, the other having 
stunted wings which are quite small. Length of forewing: 23 to 25 mm. Tibet. This species has been dealt 
with in Vol. II, p. 97, and figured there. 
D. perornata Moore (Vol. II, t. 17 h) is very much like the preceding, but the head is black, the light perorna/a. 
ground-colour of the forewing very much reduced by the much broader, black transverse bands. The transverse 
bands are not so much bent and more angled, and now and then more distinctly interrupted. Forewing: 18 to 
21 mm. North West India and Cashmir. As to the figure and further particulars see Vol. II, p. 97. 
D. eximia Swinh. (19 c). Antennae black; head orange-red; thorax orange-red; tegulae and shoulder- eximia. 
covers with black spots; abdomen orange-red. Forewing orange-red, a basal spot, a subbasal streak on the 
costa, a curved, antemedian transverse band of spots, a similar median band, and a submarginal row of spots 
black. Hindwing orange-red, a submarginal row of spots and discoidal dots black. Length of forewing: 13 mm. 
South India. 
D. nigrescens Rothsch. (22 b) differs from eximia Sivinh. by its black wings only sometimes showing nigrescens. 
some red at the base. This form may only be an extreme subspecies of eximia , but it differs too much for being 
inserted in it, although it was thus treated in the original description. Khasia[Hills and Native Sikkim. 
D. longiramia limps. (22c). antennae yellowish-brown, with very long pinnae; head and thorax longiramia. 
brownish-yellow; abdomen carmine, except at the anal segment and at the base, with -dorsal and lateral rows 
of black dots. Forewing brownish-yellow, a spot in the cell, a serpentine line from the beginning of vein 2 to 
the proximal margin, a discoidal spot and a bent postmedian transverse line brownish-red. Hindwing carmine 
with a black discoidal luna and submarginal spots from vein 5 to the anal angle. Length of fore wing: 23 mm.

D. montana Guer. (= suffusa Wkr.) (22 c). Antennae blackish; head and thorax reddish-brown; montana. 
abdomen carmine with brown hair at the base and dorsal and lateral rows of black dots. Forewing reddish- 
brown, on the disc of the wing, as well as at the costal margin washed over with carmine, a basal dot, a dot 
above vein 1 before the middle, and a discoidal dot black, 2 very much bent, darker, postmedian transverse 
bands of spots, and a submarginal row of striae. Hindwing ocbreous-brown, with a darker discoidal spot and 
dots at the veins 1 , 2 and 5. Length of forewing: 22, $ 24 mm. South India. — heylaertsi Rothsch. (=brunnea heylaertsi.

D. albicornis Hmps. (22 c). rf: antennae long-combed, shaft white, teeth black, head chestnut-red, albicomis. 
thorax chestnut-brown, abdomen carmine with black transverse bands and lateral spots. Forewing deep 
chestnut-brown, an upper discoidal spot, a bent postmedian transverse line and dots on both sides of the veins 
1 and 2 black. Hindwing carmine, a discoidal spot and submarginal spots on both sides of the veins 1, 2 and 
5 black. $ smaller, distinguished by the chestnut-brown being replaced by a dull brown and the brown hind¬ 
wing being only suffused with red. Length of forewing: $ 26, $ 23 mm. Ceylon. 
D. rubilinea Moore (22 d). Antennae black; head and thorax suffused with an ochreous yellowish-red, rubilinea. 
forehead and stripes on the shoulders black; abdomen, except the base and anal segment, carmine, with dorsal 
and lateral rows of black spots. Forewing ochreous-yellow, intensely hued reddish-brown, with an antemedian 
and a postmedian, bent, scarlet transverse line, in which there are small black dots; there are traces of a sub¬ 
marginal, bent line, also scarlet with black dots. Hindwings more yellow, the inner-marginal area hued rosy-red.

D. coccinea Hmps. (19 d). head white, antennae black; thorax scarlet with 2 white longitudinal coccinea 
streaks, tegulae and shoulder-covers white, margined with scarlet; abdomen scarlet with rows of black dots 
on the middle segments. Forewing scarlet, the discal spaces between the veins semi-hyaline, costa and veins
