D. regularis sp. nov. (48 k). Wings and body yellowish-white instead of white as in triangularia ; the regvlaris. 
lines light brown instead of grey, fine and straight instead of diffuse and irregular; all the 3 lines parallel, the 
proximal one single, nearer to the base, the inner arm, which is rarely exhibited in triangularia, recognisable; 
median line straight, obliquely distally; subterminal line regularly undulated. Some specimens from the Khasia 
Hills (Assam), quite different from the typical Sikkim form. 
31. Genus: ]>repana Schrk. 
Proboscis present; palpi feeble, upturned. Antennae in both sexes bipectinate, in the $ far less strongly 
so. Middle tibiae with 1 pair, hind tibiae with 2 pairs of spurs. Forewing with a produced and falciform apex 
and a curved distal margin; hindwing with a rounded distal margin. In the forewing veins 6, 7, 8 are stalked, 
9, 10 stalked, 8 anastomosing with 9, 10 and forming an areola; 10 rises far above the areola. Type: D. falca- 
taria L. 
D. pallida Mr. (48 1). Forewing whitish, in the $ powdered with light grey and in the $ with brown pallida. 
fringes; lines double, light with dark edges, the proximal line dentate and angular on the median, the distal 
line obliquely distally and on vein 7 sharply angular, then obliquely proximad and nearing each other, the 
proximal pair strongly dentate towards the base, the distal line straight, brown, bordered with whitish, an 
intense spot at the base of vein 10, another spot below it in the cell-fold; at the upper branch of the disco- 
cellular an angular mark and at the lower cell-angle a round grey spot; a submarginal light dentate line 
of small crescents with dark markings at the dents; hindwing lighter with a black spot at the upper and lower 
ends of the discocellular; the distal line is curved, uniformly double, dentate, composed of small crescents, 
the dents showing towards the base; median area of forewing in the $ more or less suffused with brown; in 
the $ only towards the costa with grey. Sikkim; in the Tring Museum also a small $ from West China. 
D. dispilafa sp. nov. (48 1). Forewing greyer than in pallida Mr., the distal portion of the double dispilata. 
proximal line much less angular, the space between the two arms darker. At the cell-end no black spots, but 2 
round dark grey spots with deeper grey edges, one of them at the apex of the discocellular encloses an angular 
black mark, the other spot at the lower cell-angle; the distal arm of the distal line is much more bent; light 
rust-coloured, behind it no light line, the angle on vein 7 obtuser and not so near to the distal margin. The 
distal line in the hinclwing is much plainer; before the dark marginal area there is no distinct light line. Sikkim. 
— This species which was taken to be an aberration of pallida seems to me to be entirely different. 
D. hyalina Mr. (48 1). Forewing whitish, slightly powdered with grey; 2 undulating grey proximal hyalina. 
lines and 2 distal ones; the distal arm at the hind-margin is expanded into a band; subterminal lines formed 
of indistinct grey dents; a dark spot at the lower cell-angle; hindwing with but 1 proximal line. Dharmsala 
(Penjab). 
D. subobsoleta sp. nov. (48 1) resembles hyalina with which it was confounded; wings of a purer subobsoleta. 
white, with hardly visible markings. Apparently confined upon Kulu in the Penjab.

B. rufofasciata Hmps. (48 1). Forewing light brownish-grey with a broad diffuse yellowish-brown rufofascia 
median band containing 2 whitish costal spots with a dark red-brown spot between them and 2 less distinct 
ones at- the hind-margin. ' The angular discocellular is dark, at the lower cell-angle ending in a small round 
spot composed of 3 small spots; an antemarginal row of black spots and below the apex a yellowish-red marginal 
cloud. Hindwing less yellowish-red with a black dot at the lower cell-end; a dentate distal line of small 
crescents and a submarginal row of dark vein-dots. Under suiface lighter, the reddish-yellow area of the forewing 
closed by a straight yellowish-red line parallel with the distal margin. Sikkim. 
D. ochreipennis Hmps. Forewing yellowish ochreous, very finely powdered with grey, towards the ochreipen- 
apex dull yellowish-red; the proximal and distal lines are brown, dentate, before the former and behind the ms - 
latter white triangles filling the dents, the subterminal line formed of grey triangles; in the middle and at the 
lower end of the discocellular a small dark dot; at the distal margin a dark brown line. Hindwing lighter. Sikkim. 
— A very small species. 
D. undulifera Hmps. Forewing light ochreous, feebly tinted with ochreous, with 2 dark lines, a proximal undulifera. 
and a distal one, the latter being angular behind the cell, composed of crescents, dentate; at each end of the 
discocellular a small dark spot; hindwing white. 
D. dentifera sp. nov. (48k). Forewing whitish-yellow, speckled with brown atoms; proximal line dentifera. 
dentate, very indistinct, curved, formed of brown atoms, with whitish triangles in the dents. "Distal line 
distally angled on vein 8, then inwardly, oblique and straight, the grey dents showing towards the base, distally 
filled with white triangles;-right- in front of the distal margin a dentate grey subterminal line; the base of the
