tails edged with white. UNDERSIDE, forewing ochreous-red, with a brighter red pale- 
bordered streak at the base of the cell, a band across the middle of the cell, another at its 
end, and a similar discal band which has a slightly dusky lunulated border at the upper outer 
end, a submarginal slender black slightly sinuous line. Hindwing white, the costal border 
and apex being slightly red, with the basal and subbasal spots entirely black ; a duplex 
slender black streak at the enl of the cell, a similar one above it, a discal zigzag duplex 
line, and a single black submarginal line ; a large anal and a subanal black spot surmounted 
by metallic-blue scales, which also traverse the intervening subanal space. FEMALE, 
UpPERSIDE, forewing somewhat paler brown thanin the male, the red band of the same width 
and quadrangular form. Aézdwing pale violet-brown, the discal area somewhat red-streaked ; 
above the tails are four black spots surmounted by lilac scales.” UNDERSIDE, doth wings as 
inthe male. (Joore, 1. c.) 
This is probably the commonest species of the genus, and seems to be particularly plenti- 
ful at Rangoon. It occurs as far north as the Chittagong Hill Tracts, where it was obtained 
by Mr. H. M. Parish in February and November. The female of this species has 
a strong superficial resemblance to that sex of Biduanda thesmia, Hewitson, and in the 
Mergui Archipelago the two species occur together. They are very similar on the upperside, 
but on the underside D. Joisduvalii may be distinguished by having the apex of the forewing 
concolorous with the rest of the wing, while 2. thesmia has it dusky, and moreover the duplex 
discal band anteriorly filled in with the same colour ; in the hindwing in D. doisduvalii the outer 
double costal bar extends from the costal nervure to the second subcostal nervule, the discal 
double fascia commences from the second subcostal nervule ; in B. ¢hesmia the outer double 
costal bar crosses the subcostal interspace only, stopping short at the first subcostal nervule, and 
the discal double fascia commences from the first subcostal nervule instead of from the second. 
These differences in the hindwing hold good for the males also, I havea strong suspicion 
that B. thesmia is a mimic of D, bozsduvaldi on the underside in both sexes, but on both 
sides in the female, Mr. Doherty being of opinion that Drufadia is a protected genus, of 
which Biduanda is a mimic. 
The figure shews both sides of a male specimen in my collection from Rangoon. 
D. moorei, Distant, occurs in the Malay Peninsula, Sumatra, and Daat Island. On the 
upperside of the forewing in the male it resembles Biduanda thesmia, Hewitson ; the hind- 
wing however resembles D. boisduvalti, Moore, so the male combines the characters of 
both these species. The female of D. moored differs from Burmese specimens of 2B. thesmza in 
having only a reddish suffused spot on the disc of the forewing on the upperside instead of a 
broad orange band, but agrees in this particular with specimens from the Malay Peninsula,

with an irregular reddish spot or suffusion situated at the end of the cell and at the bases of the median nervules. 
Hindwing bright and somewhat pale bluish ; the posterior margin black, inwardly bordered with white near the 
anal angle, where there are two transverse black marginal spots ; the ci/ia white; tazds blackish, with 
marginal white cilia ; costal area pale hyaline, darker near base ; upper portion of cell and basal area between

is fuscous. UNDERSIDE, /ovewing reddish-ochraceous ; a broad basal and a transverse medial fuscous streak 
in the cell, a pale fuscous line at the end of the cell, and two transverse, narrow, waved fuscous fascie between 
the end of the cell and the outer margin. Aindwing greyish-white ; the costal margin more or less suffused 
with reddish-ochraceous, and with ten large fuscous discal spots, the upper six of which are subquadrate but 
irregular in size, and the posterior four are more irregular in shape, and have their centres more or less greyish ; 
a submarginal and marginal fuscous line, the first of which is broken and irregular, and between which 
and the margin is a narrow fuscous streak, leading to a long, pale bluish-fuscous spot ; beneath the sub- 
marginal line near the abdominal margin are two narrow ochraceous fascia, which amalgamate inwardly, 
and between which the colour is pale metallic-bluish. Body above fuliginous-brown, beneath greyish-white. 
Legs greyish-white, annulated and streaked with fuscous. FEMALE. UpvrersIDE, doth wings much paler 
than in the male. Aindwing pale fuliginous-brown, excepting near the anal angle, where there is an obscure 
bluish patch with a few obscure fuscous marginal spots, UNDERSIDE, both wings asin the male, but the 
Jorewing paler in hue,”
