LYCAINIDA., SINTHUSA. 483 
FEMALE. UPPERSIDE, forewing with the costa broadly, the outer margin more broadly, 
the apex broadest of all, black ; the rest of the wing bluish-purple, occupying the lower half 
of the discoidal cell. Azndwing with the costa and outer margin broadly black, the abdominal 
margin pale fuscous, the dise bluish-purple, with the anal lobe black, inwardly marked with q 
dull ochreous line, outwardly with a line of metallic green scales, leaving the middle of the 
lobe black, UNDERSIDE, doth wings pale vinous brown, Forewing with a round dark spot 
near the base of the discoidal cell, a large quadrate spot closing the cell, a discal catenulated 
band consisting of seven spots, the series strongly broken in the middle, the three lower spots 
below the third median nervule being shifted strongly inwards, a spot in the submedian 
interspace just below the origin of the first median nervule, a macular indistinct submarginal 
fascia. Hinawing with a large round rich deep brown spot in the subcostal interspace near 
the base of the wing, a duplex heavy spot on the disco-cellular nervules, an irregular discal 
catenulated macular band, its lower portion shaped like a bill-hook, the handle of the hook 
on the abdominal margin, with a rounded spot above it on the margin near the base of the 
wing ; the anal lobe intensely black, a small round black spot in the first median interspace 
on the margin faintly surrounded with ochreous ; between this spot and the anal lobe is 4 
patch of brilliant metallic green scales, which are continued up to the abdominal margin ; 
a fine anteciliary black line, inwardly defined by an equally fine white line. 
This description has been made from a single female example taken by Mr. R. Wimberley 
in the Andaman Isles. The species must be very rare, Mr. Hewitson’s locality for it, ‘* Kast 
India,” is terribly vague.

‘*MALE. FOREWING, small, somewhat broad ; costa arched at the base, apex pointed 
extertor margin slightly oblique and convex, fosterior margin canvex near the base ; szzdcosta] 
nervure five-branched, /rst subcostal nervule emitted at nearly one-half, second at one-fourth, 
and ¢hird from near the end of the cell, third bifid near its end ; discofdal cell extending to 
half length of the wing ; dsco-cel/ular nervule slender ; discoidal nervule from its middle ; 
first median nervule at more than one-third and second median from near the end of the cell ; 
submedian nervure straight. HINDWING, small, short, broad, costa arched in the middle,

broad, triangular, extending half the wing ; frst sabcostal nervule at one-half before the end 
of the cell ; désco-cellular nervule oblique, slender ; désco¢da/ nervule from its middle ; frst 
media nervule at nearly one-half and second median from near the end of the cell ; sudmedian 
and zzfernal nervures recurved. Pa/fz porrect, second joint long, third joint short, slender, 
pointed ; avfenne with a large thick-pointed club. Type S. zasaka, Horsfield.” (Afoore. 1. c.) 
In the forewing of the type species the costal nervure reaches toa little beyond the apex 
of the discoidal cell, the first subcostal nervule originates at about two-thirds of the length 
of the cell from the base, and is bowed upwards towards the costal nervure, which it almost 
touches for some little distance, the second subcostal is given off aboyt midway between the 
bases of the first subcostal and upper discoidal, the third subcostal is short, and arises nearer 
to the apex of the wing than of the cell; the disco-cellular nervules are upright, 
nearly straight, the middle shorter than the lower; the second median nervule is given off 
some little distance before the lowere nd of the cell; in the male the inner margin is bulged 
out just before its middle,and furnished witha tuft of hairs attached to the margin and 
turned forwards. Inthe hindwing there isa small anal lobe in addition to the single tail; 
the disco-cellular nervules are straight and strongly outwardly oblique, of equal length ; the 
male is furnished with an oval depressed (as seen from above) glandular patch below the 
costa extending posteriorly slightly into the discoidal cell, and occupying the area formed by
