Rh. aurifera Btlr. (= castor Bsd. nec Wkr.) (68 e). The typical form with a fallow darker colouring aurifera. 
and intensely lustrous golden brown abdominal sides likewise occurs in North India and Assam. sumatranus sumatranus. 
Clk. is the Sumatran form which, however, exhibits a still larger and more distinct median spot of the forewing *). 
— chinensis Mell is smaller than the North-Indian form without or with much less brown and more olive on the chinensis. 
wings and thorax, the ochreous brown abdominal stripes being paler, sometimes, especially in the insects of the 
latter part of summer, much less extensive and dense; beneath the chest and abdomen are less light, dotted dull 
red; from Kwangtung. — formosanus Clk. approaches sumatranus by the darker colouring, but the stigma of formosanus. 
the forewing is smaller than here, the distal-marginal band is more distinctly marked than in aurifera and 
chinensis ; Formosa. — Larva green, in the sides the oblique stripes are so broad that their white colour predo¬ 
minates; the sham-eye on the 4th ring is large; horn graphite-grey, very thick; probably on Polygonum 
japonicum. 
Rh. rubetra B. & J . (47 f). Thorax and forewing considerably darker than in aurifera-, head and thorax rubetra. 
edged with a whitish band extending above the eyes to the palpi. On the forewing sooty black clouds excepting 
only the distal area and the distal portion of the median area. Hindwing, except the abdominal area, deep 
blackish-brown. I. of Nias. 
Rh. confusa B. & J. (= albomarginata Hm/ps. nec Bothsch.) (68 e) is one of the larger species, forewing confusa. 
rather monotonously nut-brown, marginal area scarcely lighter in the apical region, with a large stigma which, 
however, is often covered by a nebulous band; hindwing in the basal half black, but before the centre of the 
nut-brown marginal band lighter yolk-colourecl. Sikkim and Khasia Mts. in Assam. 
Rh. castor Wkr. nec Bscl. (68 e) is one of the more variegated species, the apex being very falcately castor. 
produced; very similar to olivacea (68 e), but the forewing narrower, the distal margin not so long as in olivacea. 
Body and forewing olive, abdomen with golden brown sides though not so bright as in aurifera (68 e). Between 
the undulate oblique lines of the forewing and the margin there are whitish layers, before the margin of the 
hindwing golden yellow ones. From Java. » 
Rh. olivacea Mr. (= castor Mr. nec Wkr.) (68 e) is quite similar; beside the differences mentioned in olivacea. 
castor there are two red straighter oblique lines on the forewing instead of 3 or 4 blackish brown, strongly notched 
ones. — Larva leaf-green, with a large yellow-edged sham-eye on the 4th ring; from this eye to the head a 
yellow longitudinal line. In the sides white oblique stripes alternating with green triangles. On Impatiens, 
Balsamina etc. — North-West India, Himalaya, and Khasia Mts., to the north as far as Southern China, in 
many places common. 
Rh. lunata Bothsch. (47 h). Above and beneath still more variegated than the preceding ones; forewing lunata. 
with a greyish-yellow brightening in the apical area, hindwing with an orange red macular band. Stigma of 
forewing large, but not very conspicuous in the dark ground of the wing. Beneath bright rusty red, the marginal 
areas of both wings violet, proximad irregularly defined. The typical form occurs in the Khasia Mts. in Assam. 
— sikkimensis B. & J . differs from the type in the absence of red-brown spots at the metanotum, the abdomen sikkimensis. 
is laterally less bright red, and the wings are broader. From Sikkim. 
Rh. gloriosa Btlr. (47 g). Forewing magnificently purple brown with uniform light chestnut transverse gloriosa. 
bands; hindwing with an orange band parted by dark. On the whole very similar to lunata. From Sikkim, 
Bhutan, and the Jaintia Mts. in North India. 
Rh. swinhoei Clk. described according to a single from Siam (?), is said to be still more beautifully swinhoei. 
coloured than gloriosa. Forewing Morocco-red, behind the middle strewn with small purple scales. Stigma 
small, black. The wings are traversed by 3 fine darker antemedian, median and postmedian lines. In the 
marginal band the Morocco-red remains on the veins as far as the margin. Hindwing dark red-brown, along 
i the veins and margin darker. 
Rh. albomarginatus Bothsch . (47 e) is easily recognizable by the distinct white costal stripe of the forewing, albomargi- 
Otherwise very similar to rubetra (47 f), but without the white metathoracal edge and with a brighter ochreous 
spot on the hindwing. From Sikkim and the Khasia Mts. in Assam. everetti B. & J., from Sumatra and everetti. 
Borneo, has differently shaped palpi; the white costal stripe is not distinctly prominent. dichroae Mell, dichroae. 
from South China, is smaller, more olive and with hardly any brown on the wings and thorax. The coppery 
golden brown on the metathorax and chest as well as the lateral stripes on the abdomen are lighter yellowish- 
brown. Stigma mostly indistinct. Southern China **). — Larva grey, sham-eye on the 4th ring not so large 
as in the other larvae known of Bhagastis. On the sides very thick and long white oblique stripes, the last of 
which begins at the horn and extends to the last prolegs. The horn itself is slightly flawed and with an insigni¬ 
ficant swelling above the base. On Dichroa febrifuga or Hydrangea and other plants. Imagines not rare at 
most of their habitats. 
*) Beside this Sumatran form another Bhagastis being unknown to me was described from Sumatra and deno¬ 
minated: Rh. mjobergi Clk. 
** It may be that Rh. leucocraspis Hmp.s. described from -India" and being unknown to me belongs to this or 
a neighbouring form.
