D. fasciata Moore (5b). Forewing uniform pale bluish green, with slight black irroration subterminally; 
a black mark at base; a diffuse shade of deeper green before inner and beyond outer line; lines indicated 
chiefly by difference of tint, faintly black scaled, the inner rounded and waved, ending in a black mark at 
inner margin; the outer lunulate-dentate, incurved below middle; a square black blotch between orbicular 
and reniform stigmata which are pale green, their converse lateral edges slightly marked with black scales; 
clavifonn denoted by a black spot at its apex; subterminal line marked only by a black costal triangle before 
apex; fringe green, the tips mottled black and white; hindwing greenish white, with large grey cellmark and 
some grey spots indicating an outer line; fringe white. From the Punjab and Sikkim, N. India; also found in W. China. 
Sect. II. Antennae of cf 1 serrate with sessile fascicles of cilia. 
D. chrysochlora limps. (8 i). Forewing bright yellow green, with a suffused band of dark green before inner 
and beyond outer line; a short dark basal streak; inner line wavy, double, black filled in with green; stigmata 
green defined by brown, the clavifonn large, the orbicular small and rounded, separated from reniform by a 
brown patch; outer line also double, filled in with green, indented on the folds, angled outwards on veins 4 
and 1: submarginal line pale, defined only by the edge of the prsesubmarginal shade; a row of black and pale 
lunules along termen, the lower ones whitish; fringe green with dark lunulate chequering along tips; hindwing 
reddish brown; fringe brownish grey with a dark line through it. Khasia Hills, Assam. 
Sect. Ilf. Antennae of ? ciliated simply. 
D. muscosa limps. (= imray limps). (8 i). Forewing blue green, the costa black except at base; a 
black edged white spot at base; a short white dash in submedian interspace; a subbasal white point on costa 
followed by a black patch reaching to median vein; inner line formed by a white costal point, a black spot 
in submedian interspace, and a white spot between two black ones on inner margin; stigmata white defined 
by black; the orbicular small and round; the reniform oval, with green centre and black point in upper and 
spot in lower part: a black median bar from costa, below middle oblique and linear; veins beyond cell white; 
outer line marked by a black dot on vein 6 and oblique denticulate line from vein 4 to inner margin; a 
broad black subterminal band broken by white teeth between veins 4 and 2; a white spot at vein 6; termen 
with black bar from apex and blotch at vein 6; terminal striae black; hindwing whitish, suffused with black 
in costal and terminal areas; innermarginal area clothed with brown hairs; fringe white intersected with black;

D. discibrunnea Moore (5c). Forewing grass-green on a whitish ground; a black spot at base; inner 
line black, interrupted, outwardly edged with white; a short rufous brown streak between basal and inner 
lines in lower half of submedian interval; outer line obscure, lunulate-dentate, edged inwardly by white, and 
followed by a blackish green band with dentate edge, externally followed by the white submarginal line; both 
lines and the band between them are interrupted by dull olive rufous streaks, between veins 6 and 7, 3 and 
4. and between submedian fold and vein 1; the top one between 6 and 7 is extended basewards to reniform 
stigma and the space between it and orbicular; stigmata green edged laterally first with white and then with 
black, the space between them dark green; a row of dark green lunules along termen; fringe green with outer 
half chequered whitish and purple; hindwing dull whitish, with grey cellspot and outer line; a grey terminal 
border darker at apex; fringe in basal half delicate pale green, outer half white dotted with purple. A North 
Indian species, found in the Punjab, Sikkim, Bhutan, and Assam; — a form from the Punjab, ab. olivata ab. 
nov. (= ab. 1 limps.) is suffused with olive green. 
D. beryllodes Turner (5d). Forewing grass-green; a black spot at base; the lines black, conversely 
white-edged; the inner angled and interrupted, preceded by an interrupted rufous shade, plainest at costa; 
outer line sinuous, incurved on both folds, followed by a rufous band across wing, the irregular outer edge 
of which is black in places and forms the submarginal line; a waved thick black median shade, touching the 
oblique white-edged black-centred reniform stigma, and preceded by an oblique white spot representing the
