SCALY WINGED COPEOGNATHA. 45 
stout teeth before the apex there is an indication of a minute blunt 
denticulation ; between the base and the first tooth, on the inner 
side, a row of bristly hairs. 
Hinder tibize 1:12 mm. long; outside with 3 spurs, inside with 
7 spurs, in addition to the terminal spurs of which there are 4 inside 
and 2 outside ; each spur with a ctenidiobothrium which exhibits 
the same structure as in the first posterior tarsal joint. The length 
of the first, second, and third hinder tarsal joints is 0°67 mm., 
0°07 mm., and 0:09 mm., the ratio being as 74: 3:1. First joint 
of the posterior tarsus with about 25 ctenidiobothria, which are very 
broad and arcuate ; the marginal bristles are fine hairs ; along the 
arcuate margin there is a row of very small black pigmented points, 
with two terminal spurs. 
Femora and tibiz, in their whole length, beset with narrow silvery 
scales (coloured brown on the brown tracts), which are abruptly 
truncate behind. 
Fore wing with a tail-like outgrowth at the outer margin between 
m* and m,, whichis short and rounded in the male (fig. 37), long 
and acuminate in the female (fig. 38). 
The extraordinarily dense and differentiated scaling of the fore 
wing occasions an unusual likeness to the marking of a moth’s wing, 
as can be seen from figure 2. The colouration is essentially as fol- 
lows :—The ground colour is brown; four narrow silvery cross bands, 
which are acutely notched outwards in the middle, divide the wing 
into four quarters, the two first bands occurring close beside one 
another at the end of the first quarter, the third in the middle, 
the fourth approximately at the end of the third quarter. The pos- 
terior halves of the two first bands are golden, much reduced and 
interrupted, the first not reaching the fore margin ; the third is 
interrupted in the middle, and is considerably wider in the 
posterior half; the fourth is golden in the posterior half, thin 
and linear, usually much diffused in the middle. The third and 
fourth bands are distinctly seamed with black brown in the anterior 
half ; between them about 5 golden streaks run from the anterior 
margin, in front interrupted nearly equally by brown streaks which 
soon fuse and disappear behind (hardly + of the wing breadth), only 
the most external of them runs into the angle of the notch of the 
fourth silver cross band. Between the posterior halves of the third 
and fourth bands occur irregular golden spots, here and there also 
silver scales. The anterior half of the outer quarter of the wing is 
occupied by a roundish reddish golden spot into which a prominent 
silvery wedge-shaped spot projects from the end of the fore margin, 
the base of the wedge lying upon the fore margin and its catheti
