B. scaeva Hew. (159 f) is much smaller and more delicate than the preceding, the forewing does not 
exhibit any red or brown discal spot, but the rf has a blue lustrous spot in the disc of the forewing. Hindwing 
in the $ with a light blue gloss almost to the centre of the wing, in the $ beyond the centre. Malacca and 
Sumatra. 
B. thaenia Drc. (147 c as taenia ) resembles scaeva beneath, but above it is quite dark brown with a 
shortened white oblique band in the disc of the forewing; the hindwing only shows in the distal portion a dull 
violet reflection. Borneo. 
B. melisa Hew. (146 B d) is easily discernible by showing a white spot instead of the blue discal spot 
of scaeva- $; the under surface on its dingy white ground shows blackish streak-markings which are only partly 
filled up with brownish. Sikkim, Burma; apparently rare. 
B. nicevillei Doh. above violet, much more abundantly coloured and bluer than thesmia (159 d), 
in the centre of the forewing somewhat lighter; a narrow smooth margin is black. Handwing with 2 black 
subanal spots, proximad an area powdered with white, in the subanal region a black and white marginal line. 
Beneath both wings are like melisa (146 B d), the marking is more yellow ish-red, less dark brown, the basal 
spot is plain, not ring-shaped; transverse bands of forewings yellowish-red or red-brown in various shades; in 
the hindwing the margin is at the apex of a bright rust-colour, the subanal metallic green patch large; submarginal 
line on both wings straighter, less undulate. Myitta in Tenasserim (Burma). — Unknown to me. 
B. cyara Hew. (146 B d) is certainly more closely allied to nicevillei than it appears from the rather 
different upper surface. Beneath the dark markings are likewise only partly filled up with brown. The upper 
surface on the forewing of the $ shows a large orange-red spot of an angular shape; before the anal margin 
there are crescents of small bluish-white scales. Sikkim. — The $ is unknown to me. 
B. namusa Hew. (146 B e) is easily discernible from cyara by the spot on the forew ing above represent¬ 
ing a dull yellow, somewhat undulate oblique band. Hindwing w ith very fine submarginal w hite streaks before 
the anal-marginal area. Beneath the markings are bordered with dark brown streaks, but only those in the 
proximal half of the wing are of a deeper brown, the others being lighter. Celebes. 
B. naenia Hew. (146 B d). Above quite brown, so that a great resemblance to Marmessus sumatranus 
(159 f) is produced. The $ has almost exactly the same upper surface of it, but both sexes have beneath a 
ground-colour of the forewings, which is hardly darker than the (dingy white) hindwing, whereas sumatranus 
shows beneath earth-brown forewings. Celebes. — naenia has so far always been ranged among the Biduanda, 
but it is presumably more closely allied to Marm. moorei. 
B. thaliarchus Stgr. Here the upper surface of the q is dark violettish-black, the veins, particularly 
the median branches are partly red-brown. The $ has behind the centre of the forewing a white or yellow- 
oblique band beginning at about 1 / s of the costal margin and extending tow ards the anal angle without reaching 
it. Beneath similarly marked as naenia: the rows of spots are more band-shaped. Described from the Minahassa 
(Celebes). 
B. theaa Fldr. (159 e) is very easily recognizable by the white discal band of the forewing and the 
white apex of the hindwing in the $, whereas the $ by the forewing beneath exhibiting a brown apical half 
and a white, very little black-spotted proximal half. Above the $ is quite blackish-brown. The typical form 
occurs in the Philippines, the species being before us from Palawan. Rosales. Sibulan, Eastern Mindanao, and 
Davao; it is apparently common. 
B. scudderi Doh. is based upon 1 specimen from Mergui; allied to thesmia , forewing with a red discal 
spot occupying about 1 6 of the surface of the wing, in the subapical area a spot exhibiting a blue gloss in a 
certain light. Recognizable by the upper surface of the hindwdng which is strewn with whitish in the disc. 
66. Genus: Itatliimla Mr. 
A very neat species being above and beneath remarkably coloured and marked has given rise to founding 
this genus. Forewing very broad, already soon after its base, so that the costa appears very convex. Hind wing 
also very broad and its anal portion being still a little more produced than the apical portion exhibits 3 small 
tails the middle one of w hich is the longest. The larva has quite a number of spine-like pointed, but soft cones 
of a glaring colour. The d imago has no scent-spot; both the sexes are also equally coloured. The best place 
to range this genus is presumably after Biduanda. 
R. amor F. (= triopas Hsf.) (146 B f). Above dark brown with a short ochreous-whitish demi-band 
in the disc of the forewing; hindwdng w ith small red submarginal crescents grow ing narrower towards the apex. 
I nder surface light ochreous-grey with a dark brown apical third which is defined in a bow against the light 
ground-colour. On the white under surface there are numerous dark hook-shaped or comma-shaped spots; 
before the margin of the hindwdng an arcuate line proximally bordered with white and decorated with small 
metallic green scales. — Larva green with purple red cones of different length; on Eugenia ceylanica, Hopea,
