uniformis ab. nov. (16d) the forewing is uniformly dull rufous with all the markings blurred. Found only in uniformis. 
the Khasia Hills, Assam. 
0. ( ?) dinawa Beth.-Baker. Forewing rufous ochreous, the apical area from middle of costa dinawa. 
to termen above tornus suffused with dark brown; below cell near base is an isolated black point; sub- 
basal line dark, sinuous, from costa to inner margin; lines double, black, filled in with white; the inner 
waved, oblique from costa, and incurved in cell; the outer bent outwards below costa, denticulate, out 
curved above and incurved below vein 4; the subterminal ochreous, preceded by blackish suffusion as 
far as vein 2, below which it becomes obsolescent, and with some blackish scaling beyond it between 4 
and 6; claviform stigma marked only by some black scales at extremity; orbicular with slight white 
annulus, outwardly defined by black scales; reniform with white annulus and white suffusion above it, in¬ 
wardly defined by black, its lower part lost in dark suffusion; hindwing brownish white, darker along ter¬ 
men, with dark cell spot and outer line. Dinawa, British New Guinea. Described from a single $. 
0. ochrofica limps. Forewing ochreous tinged with olive grey, the median area between ochroiiea. 
subcostal vein and vein 1 filled in with deep olive fuscous; the lines black, double at costa; inner line 
obliquely sinuous; outer line bent outwards below costa, lunulate dentate, oblique inwards below vein 4, 
followed by ochreous as the inner line is preceded; subterminal line preceded by a darker shade, externally 
lunulate dentate; orbicular and reniform stigmata ochreous, conspicuous in the dark median area; hind¬ 
wing pale brownish. Formosa. 
16. Genus; Tracheji Tr. 
Tongue present; frons smooth, bearing a tuft of hair; palpi upturned, the second segment broadly 
scaled, the third short; thorax clothed with scales; vertex with a ridge of scales; thorax and abdomen 
crested; antennae of <§ with sessile fascicles of cilia; forewing broad, the termen crenulate; scaling purplish- 
grey and green mixed; the stigmata and lines well-developed. Larva stout, slightly humped on segment 12; 
feeding on low plants in autumn, hybernating as pupa in the ground without coccon. Type T. atriplicis L. 
« 
T. auriplena Walk. (— atriplicis Koll. nec L.) (vol. 3, pi. 43g). Differs from gnonia Btlr., the auriplena 
larger Japanese form of atriplicis L., in being much more overrun with green tints, the purple grey 
shading only remaining clear along the lines, and filling up the space between outer and subterminal 
lines like a band; the stigmata green with black outlines; the orbicular round, the reniform large with 
yellowish green rings; beyond the claviform above the submedian fold is a large diamond-shaped white 
blotch, often continued across the bases of veins and 3 and through cell beyond the orbicular as another 
white blotch; the submarginal line, yellowish green, is more tremulous than in atriplicis ; hindwing dull 
white, with broad blackish marginal border, the inner margin also narrowly blackish; cellspot and veins 
dark. The species, originally described from Ceylon, occurs throughout India, and extends into Kashmir, 
China, and Japan; but the typical form is in these localities comparatively rare, its place being taken 
by the ab. lucia Btlr. which, as far as I know, does not occur in India; in this form the outer line lucia. 
si followed by a thick dentate line, and the subterminal preceded opposite cell by whitish scaling, while 
the basal area of hindwing is more or less tinged with fuscous. 
T. melanospila Koll. (= kosakka Oberth.) (16 e). Differs from auriplena Walk, in having the large melanospila. 
white blotch beyond the claviform stigma reduced to a small whitish, sometimes greenish yellow, tri¬ 
angular mark, not continued upwards across the cell; the orbicular stigma is large, with round dark centre 
and pale green ring; the hindwing has the pale basal portion more extensive, not so clearly separated 
from the terminal border, which is not so dark. A North Indian species, found in the Punjab and 
N. W. Himalayas; like the last extending into Kashmir, China, and Amurland. 
T. microspila limps. (16 e). Differs from melanospila in being paler, the purplish ground colour microspila 
being thickly dusted with blue grey or whitish grey; the yellow green areas reduced, the upper stigmata 
both smaller; the claviform is followed by only a small white spot; the outer line is acutely dentate 
on the veins outwardly, and equally so inwardly between them, instead of forming shallow lunules; hind¬ 
wing with basal area pure white, the terminal border dark fuscous. Occurs at various localities in the 
Punjab, also in W. China. 
T. stoliczkae Fldr. (16 e). Forewing dull greyish lilac varied with olive green, this tint being stoliczkae. 
thickest in basal area, in the median area below subcostal vein, and along the submarginal line; inner 
and outer lines black, conversely lunulate dentate, approaching each other in submedian interval; upper 
stigmata lilac grey washed with pale green, with black outlines; terminal area beyond submarginal line 
generally darker, the line, which is irregularly waved and dentate, being also preceded by darker clouds
