58 SPOLIA ZEYLANICA. 
Mesothorax black above, parapsidal furrows and hind border 
yellow, the scaling at these places golden. Abdomen, in spirit- 
specimens dirty whitish, the segmental junctions brown on the 
under side, anterior half brown at the sides, apex brown : finely and 
rather closely pubescent, without scales. 
Legs yellowish grayish white, tarsi brownish yellow. The 
blackish brown coloration is distributed as follows :—The anterior 
margin of the coxe, the basal half of the femora on the under 
side and a spot before the apex, the latter sometimes very 
indistinct especially on the hind legs; on the upper side of the 
extreme base and the extreme margin of the apex ; a ring before the 
apex of the mid tibize, the hind tibie with exception of the base, 
the apex and a narrow ring in the middle ; the base and the apex 
of the first tarsal joint and the second and third tarsal joints. 
Femora flattened, especially the somewhat expanded anterior 
femora. Claws (fig. 54) slender, apex moderately acute, the tooth 
nearer to the apex much stouter than the other ; between base and 
first tooth in the middle a ridge-like prominence, between this and 
first tooth a row of bristly hairs. 
Length of hind tibia 1°34 mm. ; this carries on the outside three 
spurs, on the inside nine very short spurs in addition to the ter- 
minal spurs (four on the inside, two on the outside) ; each spur with 
a ctenidiobothrium, which presents the same peculiar structure as 
that of the first posterior tarsal joint. The length of the first, 
second, and third posterior tarsal joint is 0°83 mm. : 0°07 mm. : 
0'1 mm. ; their ratio is as 84: #5: 1. First posterior tarsal joint 
with about 29 ctenidiobothria and two end spurs ; each ctenidio- 
bothrium very broad and arcuate, overlapping its neighbour, margin 
densely hairy. Second posterior tarsal joint with one end spur. 
Femora and tibie in their whole length beset with narrow silvery 
scales (brown on the brown parts), posteriorly abruptly truncate. 
Fore wing tipped with a somewhat elongated but rounded apex 
in the male (fig. 39), which in the female is drawn out into a long 
trailing tail-like acumination (fig. 40). The marking of the wing 
which is produced by the dense scaling is shown in fig. 3 and is 
essentially as follows :—The ground colour is deep brownish black ; 
the wing is traversed by numerous, irregular, much interrupted, 
wavy, thin cross bands with golden sheen, the base of the wing, a 
zone at the hinder border and at the outer border and a central 
oblique cross band interrupted in the middle remaining free. The 
middle of the outermost cross bands is silvery. The tail-like elon- 
gated wing apex silvery, in the middle at the anterior margin a 
black spot, which indistinctly radiates posteriorly ; behind and
