vein 5 whitish; inner line blackish inwardly pale edged, waved and oblique outwards; median shade thick, strongly 
developed, oblique outwards to below 3, then oblique inwards; orbicular stigma round, filled up with brown;

border, of even width from costa to vein 3, the inner edge only continued to anal angle; the fuscous terminal 
lunules broadly edged with pale yellow; fringe mottled yellow and fuscous; vertex and shoulders pale yellow; 
anal segments of abdomen thickly clothed with masses of grey woolly down; the antennae, though a 9, are

low middle edged with yellowish white, the termen and fringe between veins 1 and 2 yellow and white; $ larger 
than (J; in the ab. pallidimacula ab. nov. the space before the outcurved portion of outer line is occupied be- pallidima- 
tween subcostal vein and vein 3 by a large diffuse whitish oval patch. Assam, Sikkim, and the Punjab. c»7a. 
Subsect. IV. Antennae of $ almost simple. 
T. coerulea Btlr. (4 e). Forewing white; the ground colour showing only in a large blotch at anal coerulea.

the basal area, the median area below vein 2, and the praesubmarginal shade in costal half suffused with blackish 
fuscous, and dusted with whitish scaling; lines black, thick; the inner angled outwards on subcostal vein, then 
waved and nearly vertical, marked on inner margin by a white spot; outer line very wavy, outwardly oblique 
to vein 4, then inwardly, also marked on inner margin by a white spot; subterminal line black, outwardly pro¬ 
jecting at veins 7, 6, inangled on 6, then thicker and blacker, acutely angled inwards and forming a double pur¬ 
plish blotch on submedian fold in the middle of the white blotch; stigmata fawn colour, with thick black out¬ 
lines and brown centres; some slight brown pale-edged terminal lunules; fringe mottled brown and whitish;

and black and white dotting along veins; towards inner margin with dark and pale speckling; inner line black, 
oblique from costa to submedian fold, thence inwardly oblique, edged on each side by lines of white and redbrown 
scales, followed by a short streak of white and red scales along submedian fold; outer line black, lunulate, bent 
at vein 4, followed by a snow white line and preceded from costa to vein 5 by a white line swollen into
