black, white inside. The inner line is black, edged with white inwardly, oblique and indented below costa. It 
bends outwards above the inner margin. Anteriorly below the cell, a white spot and posteriorly above nervure 
1 a conjunction with the outer line. The latter consists of dots, is edged outwardly with white and angulated 
outwards below costa. Submarginal line indicated bv a few large dots. 35 mm. One <$ from New Guinea. 
B. nigrans B.-Bak. (39 a). This and the following 3 species have dark brown hindwings. Forewings nigrans. 
dark brown, still darker below cell, paler behind the submarginal line and on costa behind outer line. The inner- 
line indistinguishable. Central line faintly undulate, double below cell, somewhat indented on nervure 1. At 
disco-cellular 2 black dots. The outer line white outwardly to nervure 4, oblique up to there and undulate; 
thence curving inwards. Submarginal line delicately white, dentate. 32 mm. New Guinea. 
B. varians B.-Bak. (39 a). Forewings green and brown. The inner line white, dentate, placed rather varum*. 
far outwards. Central line black with white inner edge, somewhat oblique, undulate, incurved on nervure l 
and brown anteriorly. A black dot at disco-cellular. The outer line with wide white outer edge, dentate, slightly 
bent outwards to nervure 4, then curved inwards and vertically to inner margin. Submarginal line white with 
bold white dots inwardly. In the $ forewings are whiter, the outer line more heavily dentate. 32 mm. New 
Guinea. 
B. solomonis Swh. (39 a). Greenish white, partially brownish white. The inner line oblique and undulate, solomonis. 
indistinct, it appears to proceed inwards and differs in this from varians. Central line with white inner edge, 
somewhat more oblique than in varians, otherwise similar; rather brownish anteriorly. A black dot on disco- 
cellular nervure. Outer line white outwardly, bolder at costa and more closely inwards than in varians. Sub- 
marginal line scarcely differs. <$ 34-36 mm. New Guinea. 
B. mniois E. Prout. Similar to solomonis (39 a). Forewings pale olive-brown. The inner line does not mniois. 
vary. Central line heavily curved inwards in cell and at submedian fold and outwards at lower edge of cell and 
at inner margin. The outer line curved boldly outwards behind the cell, vertically at inner margin. Submarginal 
line very indistinct. An oblique black streak at disco-cellular. 32 mm. 1 known from Malacca. 
B. lichenopa Meyr. (== calena Swh., exquisita Luc.) (39 a). Forewings somewhat like triphaenopsis (39 b), lichenopa. 
but differing by the darker hindwings. Forewings pale greenish white with brown scales. The inner line oblique 
and undulate. The outer line white, slightly blackish inwardly, somewhat excurved to nervure 4, then turning 
inwards, somewhat more greenish posteriorly except at costa. Submarginal line black, similar to solomonis. In 
$ forewings are pale yellow-green, hindwings being paler at base and at inner margin. 30—35 mm. Queensland.

wings mostly orange-yellow with dark m argi n. 
B. ephesioides Pagst. (= brachyptera Hmps .) (39 a). Forewings short and wide, of striking red-brown ephesioides. 
colouration. The inner line black, somewhat undulate, oblique, edged with green inwardly. Anteriorly a double 
straight black line. The outer line black, green outwardly, curving outwards behind the cell, slightly inwards 
on submedian fold, fine green striations extend thence to inner line, posteriorly there are some white scales near 
to inner margin. Submarginal line delicate, green. 30 mm. Aru Island, New Guinea. 
B. donans Wkr. (----- laportei Fldr .) (39 b). Forewings grey-white, slightly brownish at base and in centre donans. 
of costa. The inner line indistinct, almost straight, somewhat closer inwards. Central line indistinct proceeding- 
outwards until the cell, then curved and vertically, black with white inner edge. A black streak at disco-cellular 
and a radial streak to outer line. The latter delicately black with wide white outer edge, angulated outwards 
below costa and curved outwards behind the lower angle of cell and turning outwards on nervure 1. Submarginal 
line consisting of bold black spots, similarly angulated as in solomonis. There are 4 forms described. — l. grisea grisea. 
Mr. There is a quadrate black spot on forewings above nervure 1 and between the inner and outer lines. 
2. donatis Strd. (39 b) has a very black stripe from disco-cellular to outermargin on submedian fold. — 3. similis donaiis. 
Strd. has forewings suffused with lilac-grey to the above-mentioned stripe. — 4. pannosa Mr. is said to be greener. snnllis - 
The central area is browner in the anterior part. At inner margin the outer two-thirds up to nervure 2 are blackish. 
35—40 mm. India, Cevlon, Tonkin, Andamans, Amboina and the Key Islands. 
pannosa. 
B. triphaenopsis Pimps. (39 b). Perhaps this is only a form of donans. Ground colour greenish white, triphaen- 
anteriorly darker in central area, occasionally a black band at inner margin. The inner line as in donans, the °P si 
central line appears to be curved rather more pronouncedly inwards at inner margin. The outer line is not so 
boldly incurved on submedian fold as in donans. There is also here a short black horizontal streak, which is 
absent in donans, whilst the short streak behind the cell is retained. Contour of wings and hindwings is identical. 
40 mm. Singapore. 
B. metachrysa Trnr. (39 b). Forewings reddish brown. The inner line somewhat closer inwards than mciachrysa 
in donans. Central line obliquely outwards, curving widely outwards between costa and submedian fold. A 
black streak on disco-cellular. The outer line is delicate, bending somewhat outwards at costa, obliquely to
