57. Genus: ISirihamoides gen.nov. 
Antenna of <$ strongly pectinated basally, suddenly decreasing towards the end, palpi short, porrect, 
posterior tibiae with 2 pair of spurs. Forewing: 7—10 stalked, 10 arises after 7, 11 straight. Hindwing: 6 + 7 
stalked, 8 connected with the anterior edge of cell only near the base, posterior angle of cell slightly projecting. 
Type of genus: B. junctura Wkr. 
B. junctura Wkr. (<$ = circinata Sn.) (88 b). Forewing brownish-red, with an oblique straight antemedian junctura. 
line and, posteriorly convergent with it, a straight line from 4 / 5 of the costal margin to the distal margin above 
the tornus, more or less striped between them. Hindwing paler. Expanse of wings: 40—50 mm. India, Borneo. 
B. birthama B.-Bak. (88 c). Body ochreous yellowish-brown. Forewing lustrous purple brown in the birthama. 
basal portion, defined by a straight oblique line from 1 / 5 of the inner margin to the costal margin before the 
apex, marginal area of the same colour as far as beyond the tornus, bordered inside by a curved line, the space 
between the two areas yellowish ochre, with a dark red cross-vein dot. Hindwing brownish ochre. Expanse 
of wings: 34 mm. New Guinea. 
B. bilineata Swh. (88 b). Dark red-brown, prothorax lighter, forewing with a straight dark transverse bilineata. 
line more or less bordered with silvery white distaily and accompanied by blackish shadows, extending from 
Y s of the inner margin to the centre of the costal margin, another similar line from % of the costal margin to 
the distal margin above the tornus, distaily curved in the + Hindwing red-brown. Anterior tibia with a silvery 
white terminal spot. Expanse of wings: 22—35 mm. Philippine Is. 
B. extincta sp. n. (88 c) is intermediary between bilineata and angustipennis. Forewing short and broad, extinda. 
red-brown, with an almost extinct, straight dark median line not bordered with white, without a distal line, 
but with an indistinct marginal shadow below the apex. Hindwing and under surface dull red-brown. Body 
red-brown, with an orange dorsal line on the abdomen, an orange prothorax which is never so light orange as 
in angustipennis. Expanse of wings: 20 mm. Bougainville. $ type from Arawa in the Tring Museum. 
B. angustipennis sp. n. (88 c) is smaller, wings mostly narrower than in extincta , interior transverse line angusti- 
less distinct, exterior line not at all bordered with silvery distaily, more oblique. Expanse of wings: 28 mm. penms.

B. circulifera sp. n. (88c). Body dark brown, fore wing purple brown to the centre, a purple blackish circulifera. 
transverse streak at the cross-vein. Beyond the lower cell-end we notice a large yellowish ochreous circular 
spot filled somewhat greyish towards the base, bordered towards the apex by a broad light red-brown band which 
narrows down towards the tornus. The margin is equably broad yellowish ochreous, fringe violettish-brown. 
Hindwing violettish-brown, narrowly yellow at the distal and inner margins, fringe yellow, dark at the end. 
Under surface purple brown, with broad yellow margins. Expanse of wings: 27 mm. New Guinea. $ type 
from the Weyland Mts. (British Museum). 
B. rubrimixta sp. n. (88 c). Body brownish ochre. Forewing brownish-red, indistinctly dusted over rubrimixta. 
with blackish purple as far as an oblique line from the apex to vein 2, so that only a broad marginal area 
narrowing down towards the apex remains of the ground-colour which is not distinctly defined. Hindwing 
and under surface dark reddish-grey. All the fringes with a distinct light yellow basal line. Expanse of wings: 
14—20 mm. New Guinea. B type from Mt. Goliath in the Tring Museum. 
B. plagioscia Trnr. (= aspidophora Loiv.) (88 c). Body and fore wing reddish greyish-brown, the plagioscia. 
fore wing with an oblique straight dark line bordered with light distaily and extending from y 2 of the inner 
margin to % of the costal margin, distaily to it two dark shadowy spots before the apex and in the inner- 
marginal half. Hindwing dark grey. Expanse of wings: 22—28 mm. Australia. 
B. dinawa B.-Bak. Body dark red-brown. Forewing red-brown with a pale, distaily dark-edged dinawa. 
straight line from the centre of the inner margin to the costal margin before the apex; distaily to it the wing is 
lighter pinkish-brown. Hindwing dark brown. Expanse of wings: 32 mm. New Guinea, August. 
B. ramosa sp. n. (88 d). Thorax and forewing dark violettish-brown, feebly powdered with bluish ramosa. 
silvery grey, a thick, sharply notched antemedian transverse band distaily bordered with yellowish extends 
from the inner margin to the cell. Postmedian line begins at the costal margin shortly before the apex, projects 
in a sharp dent towards the upper third of the distal margin and extends, in a distaily convex bow, to the inner 
margin before the tornus. The area between this bow and the notched antemedian line is lighter reddish-brown. 
Hindwing and under surface greyish-black. Expanse of wings: 16 mm. Bougainville. $ type from Arawa in 
the Tring Museum. — The $ is apparently allied to plagioscia (88 c), but as the <$ is not before me, I cannot 
decide upon the position definitely. 
58. Genus: IHmacosIlla gen.nov. 
Antennae of B shortly serrate-dentate, the dents nowhere longer than the antenna is thick. Palpi long 
upcurved, almost reaching to the vertex. Posterior tibiae with 2 pair of spurs. Forewing: 10 stalked with 
8 + 9, 7 together with the stalk, or stalked, 11 arises basacl to 2. Hindwing: posterior cell-angle projects little,
